Procedures

Fixes problems:
	- The '-r' option works differently between Info-Zip ans Winzip
"wzzip" Removal of this option allows wzzip to be used as well.

Utilities

Fixes problems:
	- Fix (FAPI) : Improving terminology in header comment to
lib/xlatmap . (lib/xlatmap [1.7]: 2002/11/02 18:03:06 igor)
	- remove the unused SYSTIME_H from the mac headers. Prefer "time_.h"
to <sys/time.h>. Although the Metroworks Standard Library doesn't have
a sys/time.h, keep the definition of HAVE_SYS_TIME_H for now to avoid a
multiple definition problem with struct timeval. (gp_mac.c [1.10]:
2002/11/14 16:55:21 giles)
	- correct an unitialized variable in the mac stream process.
(gp_macio.c [1.9]: 2002/11/14 17:12:53 giles)
	- Replace the previous gp_file_name_is_absolute with
gp_patshtring_not_bare which generally has the same sense, but is more
consistently implemented on platforms and indicates whether or not a
pathstring can be prefixed by a directory and the path_separator string.
Also, fix check_file_permissions to handle the 'bare' pathstring case when
the current directory is one of the permitted paths. Fixes SourceForge bug
#637751. (gp_iwatc.c [1.11], gp_macio.c [1.10], gp_mswin.c [1.14],
gp_ntfs.c [1.11], gp_os2.c [1.16], gp_vms.c [1.14]: 2002/11/17 22:50:32 ray)


Drivers

Fixes problems:
	- Make gdev_t4693d_map_color_rgb a functinal routine. Previously it
returned a constant maximum color value. This would cause problems with
overprint and anti-aliasing. (gdev4693.c [1.8]: 2002/11/13 19:34:56 dan)
	- Update the encode/decode color procedures when the device is
openned. This is required since the device can modify its model settings
inside the open procedure. (gdevstc.c [1.8]: 2002/11/13 19:39:12 dan)
	- Converted from old map_rgb and map_cmyk to new encode_color
routines. (gdevbit.c [1.6]: 2002/11/13 20:24:12 dan)
	- Define a decode_color proc for the cmyk devices.
(gdevcdj.c [1.13]: 2002/11/13 23:33:05 dan)
	- Convert old map_color_rgb routines to decode_color routines for
the stcolor device. Change required due to device API change.
(gdevstc.c [1.9]: 2002/11/14 20:48:47 dan)

Correct some display device map_color_rgb functions, needed for
anti-aliasing. (gdevdsp.c [1.13]: 2002/11/13 07:05:43 ghostgum)

Recorrect display device 4-bit native mode after a correction was reversed
by DeviceN. (gdevdsp.c [1.14]: 2002/11/13 07:24:03 ghostgum)

Remove duplicate call to GlobalLock in Windows printer device.
(gdevwpr2.c [1.14]: 2002/11/16 22:16:49 ghostgum)


PDF writer

Fixes problems:
	- Fix (pdfwrite) : Implement a special check for CMaps which appear
to be identity, and replace them with a standard CMap name. Source Forge bug
"[ 615994 ] CMAP is corrupted". (gdevpdtc.c [1.11]: 2002/11/02 19:16:44
igor)
	- Fix (pdfwrite) : Removing gx_device_pdf_s::random_offset because
it is not longer in use. (gdevpdfx.h [1.55], gdevpdtb.c [1.10]: 2002/11/17
22:18:15 igor)
	- Fix (pdfwrite) : Removing gx_device_pdf_s::random_offset because
it is not longer in use. (gdevpdf.c [1.56]: 2002/11/17 22:27:53 igor)
	- Fix (pdfwrite) : Improving the condition about skipping paths
outside the clipping path. SourceForge bug "[ 628542 ] (pdfwrite) wrong
gs5.98-dragon.pdf". (gdevpdfd.c [1.21]: 2002/11/18 02:53:44 igor)
	- Fix (pdfwrite) : (1) FontMatrix.ty was ignored while computing
glyph positions. (2) Working around AR4,5 bug which ignores FontMatrix.ty .
SourceForge bug "[ 629961 ] (PDF interpeter) 'Ghost' text appears again".
(gdevpdtb.c [1.11], gdevpdtt.c [1.23]: 2002/11/18 03:05:22 igor)
	- Fix (pdfwrite) : Skipping text outside clip path. SourceForge bug
"[ 608520 ] PDFWrite failed for PS File". (gdevpdfd.c [1.22],
gdevpdte.c [1.20]: 2002/11/18 14:29:54 igor)


PDF Interpreter

Fixes problems:
	- Fix for #609488 Problems in DeviceN test file. This resolves
problems that can occur if the transfer function are dependent upon the
halftone. (Which is true for the default hi res transfer function.) We were
getting variable (unpredictable) results due to the undefined ordering in
enumerating graphic state dictionaries via the 'forall' operator.
(lib/pdf_draw.ps [1.62]: 2002/11/05 00:48:01 dan)
	- resourcefont procedure didn't handle correctly font descriptor
without font stream. Bug #633714 (lib/pdf_font.ps [1.51]: 2002/11/14
21:22:22 alexcher)

Move code from pdfshowpage to pdfshowpage_finish for the benefit of GSview
which calls pdfshowpage_init and pdfshowpage_finish, but not
pdfshowpage_setpage. (lib/pdf_main.ps [1.63]: 2002/11/05 20:56:02 ghostgum)


Interpreter

Fixes problems:
	- Eliminate possible negative discontinuity in default hi resolution
transfer function. (lib/gs_init.ps [1.71]: 2002/11/05 00:30:59 dan)
	- The 'bind def' was dropped from the previous commit: Fix:
Eliminate possible negative discontinuity in default hi resolution transfer
function. (lib/gs_init.ps [1.72]: 2002/11/05 08:02:17 dan)
	- When processing an EPS file, remove any left over items on the
operand and dictionary stacks. (lib/gs_epsf.ps [1.8]: 2002/11/12 20:31:30
ghostgum)
	- Use immediate evaluation for forcesetcolorspace operator because
its definition goes out of scope when bind is delayed or disabled. Bug
#635747 (lib/gs_devn.ps [1.3], lib/gs_indxd.ps [1.2], lib/gs_patrn.ps [1.2],
lib/gs_sepr.ps [1.2]: 2002/11/13 20:23:10 alexcher)
	- Skip /ColorValues processing for devices where it is not defined
(typically grayscale devices). Fixes SF bug #636213. (lib/gs_dps.ps [1.8]:
2002/11/14 17:24:00 raph)
	- Restore silent clip of sethsbcolor values to range [0..1].
(lib/gs_cspace.ps [1.4]: 2002/11/15 18:10:24 raph)
	- Replace the previous gp_file_name_is_absolute with
gp_patshtring_not_bare which generally has the same sense, but is more
consistently implemented on platforms and indicates whether or not a
pathstring can be prefixed by a directory and the path_separator string.
Also, fix check_file_permissions to handle the 'bare' pathstring case when
the current directory is one of the permitted paths. Fixes SourceForge bug
#637751. (lib/gs_fapi.ps [1.17], zfile.c [1.23]: 2002/11/17 22:50:32 ray)
	- check_file_permissions did not handle the case where no path
separator is needed after the current_directory_name. PostScript code in
.locksafe (in gs_init.ps) was already correct. Problem would happen on Mac
& VMS. (zfile.c [1.24]: 2002/11/18 17:17:20 ray)
	- Correcting mixed DOS/UNIX line ends introduced in the previous
version. (zcolor.c [1.14]: 2002/11/18 19:14:57 alexcher)
	- FrameMaker produces PS file that assumes that the presence of
/pdfmark in systemdict implies availability of /currentdistillerparams. The
fix hides /pdfmark for all devices except pdfwrite following
set/currentdistillerparams pattern. Bug #638982 (lib/gs_pdfwr.ps [1.21]:
2002/11/18 19:36:57 alexcher)

Modified the setdevice procedure to reset the current halftone (if possible)
when changing devices. This is necessary in the DeviceN code because the
number of device halftone components must be the same as the number of
device color model components. It is also generally a good idea.
(lib/gs_init.ps [1.70]: 2002/11/05 00:10:37 dan)

Post-release cleanup for 7.32: increment version number to 7.33.
(lib/gs_init.ps [1.73]: 2002/11/05 08:31:56 raph)

Correct -dEPSFitPage when the device has non-zero margins.
(lib/gs_epsf.ps [1.7]: 2002/11/07 07:14:28 ghostgum)

Correct some display device map_color_rgb functions, needed for
anti-aliasing. (gdevdsp.h [1.6]: 2002/11/13 07:05:43 ghostgum)

Prevent access to .forceput and friends. Patch by Alex Cherepanov and
Russell Lang. (lib/gs_diskn.ps [1.4], lib/gs_epsf.ps [1.9],
lib/gs_fonts.ps [1.23], lib/gs_res.ps [1.26], lib/gs_resmp.ps [1.6],
lib/gs_type1.ps [1.13]: 2002/11/18 20:23:18 ghostgum)


Streams

Fixes problems:
	- Make init method for ASCII85Encode return 0. Fixes SF #634519.
(sa85x.h [1.6]: 2002/11/13 08:23:13 raph)


Library

Fixes problems:
	- param_check_string now checks is_valid before trying to calculate
the length of the string in question. We now handle a null
color_info.cm_name in all cases. (gsdparam.c [1.12]: 2002/11/02 17:22:29
giles)
	- Fix (pdfwrite) : Implement a special check for CMaps which appear
to be identity, and replace them with a standard CMap name. Source Forge bug
"[ 615994 ] CMAP is corrupted". (gdevpsf.h [1.21], gdevpsfm.c [1.11]:
2002/11/02 19:16:44 igor)
	- Fixing the "members" logic in gs_type1_glyph_info. Arithmetic
operations were erroneously used instead logic ones, sometimes causing a
request of undefined features. Source Forge bug "[ 629116 ] Bad font in
re-distilled PDF". (gxtype1.c [1.20]: 2002/11/02 20:07:46 igor)
	- These are a set of fixes required to make the 2 bit memory device
functional. They are being lumped together since they are all required. The
fix in gdevm2.c was found by customer #760 and is reported as bug #600281
mem_mapped2_copy_mono() incorrect. (gdevm2.c [1.5], gxcht.c [1.11]:
2002/11/05 01:03:14 dan)
	- Make some debug warning messages only occur for DEBUG build. The
most common offender seen was "No encode_color proc defined for device."
(gxcmap.c [1.12]: 2002/11/05 19:13:52 dan)
	- Define color encode/decode procedures for the nullpage and null
devices. This eliminates a "No encode color proc defined" message for these
devices. (gdevnfwd.c [1.8]: 2002/11/13 06:00:29 dan)
	- Change the substitution logic for the decode_color procedure. This
change gives preference to the map_color_rgb proc (if it exists) and the
device is an RGB device. The previous logic gave preference to
gx_default_decode_color if the device was linear and separable.
(gdevdflt.c [1.10]: 2002/11/13 19:31:28 dan)
	- Fix uninitialized memory read; gx_set_device_color_1(pgs) depends
on the value of pg->in_cachedevice, so move up initialization of the
latter. (gsstate.c [1.19]: 2002/11/13 21:51:34 raph)
	- Replace the previous gp_file_name_is_absolute with
gp_patshtring_not_bare which generally has the same sense, but is more
consistently implemented on platforms and indicates whether or not a
pathstring can be prefixed by a directory and the path_separator string.
Also, fix check_file_permissions to handle the 'bare' pathstring case when
the current directory is one of the permitted paths. Fixes SourceForge bug
#637751. (gp.h [1.13], gp_dosfs.c [1.6], gp_unifn.c [1.6],
gp_unifs.c [1.10]: 2002/11/17 22:50:32 ray)

Post-release cleanup for 7.32: increment version number to 7.33.
(gscdef.c [1.30]: 2002/11/05 08:31:56 raph)

Suppress the "No encode color proc" warning for the "null" device (a
forwarding device) where it is expected and acceptable. (gxcmap.c [1.13]:
2002/11/06 23:11:17 ray)

First commit of 7.33 beta release: update dates and version numbers, edits
to News.htm. (gscdef.c [1.31]: 2002/11/18 21:41:51 raph)


Other

Fixes problems:
	- remove the unused SYSTIME_H from the mac headers. Prefer "time_.h"
to <sys/time.h>. Although the Metroworks Standard Library doesn't have
a sys/time.h, keep the definition of HAVE_SYS_TIME_H for now to avoid a
multiple definition problem with struct timeval. (macsystypes.h [1.5]:
2002/11/14 16:55:21 giles)

Turn on 64 bit color indexes in the MacOS build. (macsystypes.h [1.6]:
2002/11/14 17:36:21 giles)







Version 7.32 (2002-11-02)




This is the second beta release in preparation for 8.0. The most
notable new feature is Well Tempered Screening, which now works for
angles of 0 and 45 degrees as well.



To test WTS, set the UseWTS user parameter:


<< /UseWTS true >> setuserparams





Also make sure you're not in a banding mode (setting
-dMaxBitmap=500000000 should work), and that your halftone
dictionaries set /AccurateScreens.



A fair number of bugfixes have also made it into this release,
including a fix for the slow rendering of PDF's in GhostView-derived
viewers.

Procedures

Fixes problems:
	- adds a missing header to gxshade for indexed color routines.
(lib.mak [1.103]: 2002/10/22 13:31:37 giles)
	- update the ECHOGS_MAK dependency to ECHOGS_XE. (devs.mak [1.80],
int.mak [1.86], lib.mak [1.105]: 2002/10/22 18:38:00 giles)
	- correct some dependencies against the include lists in the
relevent C files. Also reorder them to facilitate easer checking next time.
Closes SourceForge bug #607819. (int.mak [1.89], lib.mak [1.108]: 2002/10/28
19:17:19 giles)
	- install cidfmap on unix. (unixinst.mak [1.27]: 2002/10/28 19:27:06
giles)
	- install the example FAPI configuration files by default. Ideally
this would be dependent of enabling the fapi feature in the build.
(unixinst.mak [1.28]: 2002/10/28 19:43:42 giles)
	- provided a meaningful error message when an immediately evaluated
name can not be found. Fixes SourceForge bug #543185, Confusing diagnostics
for //undefined. (int.mak [1.91]: 2002/10/29 09:57:53 ghostgum)
	- also install the character translation FAPI config file.
(unixinst.mak [1.29]: 2002/10/31 16:01:12 giles)
	- Fiddles with makefile parameter quoting so that "make pg" runs
again. (unix-end.mak [1.5]: 2002/11/02 05:51:00 raph)

Remove the gcc version check from the macosx makefile. That platform is
unlikely to be running the version in question. (macosx.mak [1.14]:
2002/10/18 13:17:07 giles)

Use 'gcc2' as the C compiler with the macosx makefile, working around a bug
in Apple's gcc3 (the default cc). This won't work on pre-10.2 developer
tools, but users are less likely to encounter that now. (macosx.mak [1.15]:
2002/10/18 15:48:26 giles)

Corrects various include dependency problems. Closes SourceForge Bug

build. (bcwin32.mak [1.24], msvc32.mak [1.38], watcw32.mak [1.21]:
2002/10/31 10:11:03 ghostgum)

Reinstate the mswindll device because removing it also requires modifying
the exports in gsdll32.def. (bcwin32.mak [1.25], msvc32.mak [1.39],
watcw32.mak [1.22]: 2002/10/31 10:51:29 ghostgum)

Add a utility that draws glyphs on top of the character box defined in the
given AFM. Goes throuh each glyph in the AFM. (toolbin/drawafm.ps [1.1]:

20:00:12 alexcher)

Moved the redefinition of the DefaultGray, DefaultRGB, and DefaultCMYK
instances of the ColorSpace resource category to the pdfopen procedure, as
opposed to the runpdf procedure. This avoids unintended color space
substitution when using utilities such as gv, gsview, etc., which do not
invoke the runpdf procedure. Thanks to both Raph Levien and Russell Lang for
suggesting this modification. (lib/pdf_main.ps [1.58]: 2002/10/17 21:33:03
dan)

Moved the invocation of pdfshowpage_setcspacesub from pdfshowpage to
pdfshowpage_finish. This is done to accommodate gsview, which does not
invoke pdfshowpage. Thanks to Russell Lang for pointing this out.
(lib/pdf_main.ps [1.59]: 2002/10/18 17:31:26 dan)

This is a fix to handle the "slow rendering for PDF files with color space
substitution" ("-dUseCIEColor") problem. The code for the patches is the
same as in yesterday's message; some comments have been added, and some of
the earlier comments made more clear (we hope). Modified Files:
lib/gs_cspace.ps Modified the _setcolorspace procedure to ignore redundant
settings of the current color space for PDF files, even if color space
substitution is in effect. lib/pdf_main.ps Modified pdfshowpage_setcspacesub
to "transition" the current color space if color space substitution is in
effect and the current color space is a device-dependent color space.
(lib/pdf_main.ps [1.60]: 2002/10/24 04:13:50 dan)

Change some pdfformaterror messages to "Warning" to avoid user confusion and
alleviate concern. Also this should help bug reports to be less misleading.
(lib/pdf_base.ps [1.29], lib/pdf_draw.ps [1.59], lib/pdf_main.ps [1.61]:

Interpreter

Fixes problems:
	- A typo in .locksafe procedure left 2 boolean parameters on the
stack causing PS errors in some files produced by "dvips(k) 5.86" that
depend on empty initial operand stack. Bug #626437 (lib/gs_init.ps [1.67]:
2002/10/24 20:37:29 alexcher)
	- currentcolorspace didn't check whether the current device is a
cache device and always returned the value set by setcolorspace in the
current graphic state. The fix returns [/DeviceGray] as the current color
space in cache device. Bug #627169 (zcolor.c [1.13]: 2002/10/24 22:48:41
alexcher)
	- provided a meaningful error message when an immediately evaluated
name can not be found. Fixes SourceForge bug #543185, Confusing diagnostics

	- Restore ps2ascii operation (1) use .bind instead of bind in
operator redefinition to support GS operation in NOBIND mode. (2) increase
the size of operator procedure tables. Bug #628820 from Ryan Pinto

	- Adobe interpreters accept numbers as values of /C0 or /C1
parameters of Type 2 function contrary to PLRM. Adobe has also published
smooth shading examples that use this feature. So GS has to follow. Bug

18:34:25 alexcher)
	- Accept any objects as Font, CIDFont, and CMap resource keys, not
just strings or names. Ignore keys other than strings or names in
<CIDFontName>- -<CMapName> pair construction because it is
defined only for strings. Bug #602739 (lib/gs_cidcm.ps [1.10]: 2002/10/31

(lib/gs_setpd.ps [1.17]: 2002/11/01 04:04:10 alexcher)
	- Redefine .runstdin with one bound to EPSF 'run' operator so that
EPS files are handled correctly from %stdin. Code for skipping DOS EPS
header now uses the EPS encapsulating run, instead of directly calling
.runexec. (lib/gs_epsf.ps [1.6]: 2002/11/01 23:41:18 ghostgum)
	- Provide a meaningful error message when an immediately evaluated

Corrects some typos in a comment. (zcolor.c [1.12]: 2002/10/23 22:44:31
giles)

This is a fix to handle the "slow rendering for PDF files with color space
substitution" ("-dUseCIEColor") problem. The code for the patches is the
same as in yesterday's message; some comments have been added, and some of
the earlier comments made more clear (we hope). Modified Files:
lib/gs_cspace.ps Modified the _setcolorspace procedure to ignore redundant
settings of the current color space for PDF files, even if color space
substitution is in effect. lib/pdf_main.ps Modified pdfshowpage_setcspacesub
to "transition" the current color space if color space substitution is in
effect and the current color space is a device-dependent color space.
(lib/gs_cspace.ps [1.2]: 2002/10/24 04:13:50 dan)

Bump version after the 7.31 release. (lib/gs_init.ps [1.68]: 2002/10/28

Changes to Windows and OS/2 files to allow ghostscript to compile with the
graphics library and interpreter in separate source directories. Partial fix
for SourceForge bug #542848, "library #includes interpreter headers".
(dwmain.c [1.12]: 2002/10/29 09:44:40 ghostgum)

Encapsulate EPS files to make sure that at least one page is printed. Add
command line options -dNOEPS, -dEPSCrop and -dEPSFitPage for customizing
handling of EPS files. Warn if EPS bounding box does not fit in clipping
box. Enable EPS and DOS EPS processing for several platforms.
(lib/gs_epsf.ps [1.5], lib/gs_init.ps [1.69]: 2002/10/31 09:22:13 ghostgum)

Proposed log message: According to PLRM 3rd ed, p. 264 "indexed color space
is not allowed in any shading whose color values are generated by a
function; this applies to any shading dictionary that contains a Function
entry." Adobe interpreters follow PLRM in this respect and we follow them.
Bug #591768 (zshade.c [1.14]: 2002/10/31 16:19:48 alexcher)

Adds UseWTS user parameter to enable WTS, rather than a compile-time #define
USE_WTS as before. Also, WTS is now only enabled when AccurateScreens is
selected. (zusparam.c [1.8]: 2002/11/02 07:33:48 raph)

(sarc4.c [1.8]: 2002/10/29 09:22:29 ghostgum)


Library

Fixes problems:
	- adds a missing header to gxshade for indexed color routines.
(gxshade.c [1.15]: 2002/10/22 13:31:37 giles)
	- On gcc 2.95.4 for Alpha all structures are padded to 8 byte
boundary but sizeof(bool) == 4. First member of the subclass is restored
because it is overwritten by padding data. Bug #613909 (gximage3.c [1.11]:
2002/10/25 00:27:10 alexcher)
	- correct some dependencies against the include lists in the
relevent C files. Also reorder them to facilitate easer checking next time.
Closes SourceForge bug #607819. (gscolor2.c [1.14], gxclrast.c [1.26]:
2002/10/28 19:17:19 giles)
	- For Type9 fonts (CIDFontType 0 with Type 1 or Type 2 leaf fonts),
the leaf's FontMatrix was being ignored. Catch the change of leaf font index
in select_descendant_font, and for Type9 (ft_CID_encrypted) concatenate the
leaf's FontMatrix in show_state_setup. Fixes SourceForge bug #576591 for
Artifex customer #1110 [footnotes rendered too large: badcharsize.pdf]

	- Propagate error codes from gs_distance_transform_inverse. Patch
from Forrest Cahoon, improved. (gxstroke.c [1.7]: 2002/10/31 09:00:28 igor)
	- Fix incorrect calculation of the clipping path around the pattern
tile. Old code used bounding box of the tile in device coordinate system as
a clippin path. When the tile was not aligned with device coordinates the
box extended beyond the tile parallelogram causing incorrect rendering of a
pattern depending on clipping path. New code draws correct clipping path by
taking advantage of high level functions. Also gs_bbox_transform() was moved
out of compute_inst_matrix() to improve readability. Bug #595378
(gsptype1.c [1.13]: 2002/10/31 16:34:01 alexcher)
	- Default allocator added to the stable allocator because it is used
in s_zlib_alloc() when the clist is stored in memory. According to
doc/Develop.htm: "Every allocator has an associated stable allocator, which
tags pointers with the same VM space number but which is not subject to save
and restore. System VM is intrinsically stable (its associated stable
allocator is the same allocator)" Bug #530588 (gsmalloc.c [1.11]: 2002/10/31

Other

Add real 'make distclean' and 'make maintainer-clean' targets. These are no
longer general no-ops but are the responsibility of the platform-specific
makefiles. The autoconf build now removes its generated files from the
top-level directory when requested. (Makefile.in [1.18]: 2002/10/24 12:57:57
giles)

Remove configure.ac only on maintainer-clean. It's more transparent to
distribute this file as well along with configure. (Makefile.in [1.19]:
2002/10/24 13:25:01 giles)







Version 7.31 (2002-10-17)




This is the first beta release in preparation for 8.0. A great many
bugs have been fixed since the 7.30 alpha release, and it should be
stable for most users. Two features planned for 8.0 are not yet fully
functional, however: subpixel positioning of antialiased text, and
Well Tempered Screening (the latter can be enabled for experimentation,
but does not work for 0 and 45 degree angles).

A few regressions remain. See the archives
of the regression report for more details. Another known issue is slow
rendering of PDF's from GSView and Ghostview family viewers.


Incompatible changes




The -dDOPS flag (to enable DoPS processing) is now
disabled by default, as it is a more reasonable default. Thus, any
files which depend on DoPS will now break unless this flag is set.






Documentation

Fixes problems:
	- Mentions the autoconf build method in the installation
documentation. Inspired by a user report of having looked there first rather
than at Make.htm; an understandible choice based on linux packaging
conventions. (doc/Install.htm [1.35]: 2002/09/16 21:15:39 giles)
	- Keep pagedevice and device views of .LockSafetyParams correct even
after a 'restore' is used to unlock. The dictionary fed to the setpagedevice
operator is allocated in the same VM space as currentpagedevice to avoid
invalidaccess problems. Fixed SF #580029 and does not revert to the
incorrect behaviour of bug #516379. (doc/Language.htm [1.53]: 2002/09/18

Procedures

Fixes problems:
	- Fix (pdfwrite): Virtual function same_font cannot work properly if
arguments have different representation (particularly for comparing an
original font with its stable copy). Due to it pdf_font_resource_t::Widths
mixed widths taken from fonts variations with different metrics. Entirely
changing the logics of creating font resources with new function
gs_copied_can_copy_glyphs. Source Forge bugs : #596394 (pdfwrite) Wrong

font spacing/ragged edge on text column (devs.mak [1.73], lib.mak [1.96]:
2002/09/08 20:20:12 igor)
	- Fix (pdfwrite) : Completely removing the generation of "space
chars", because they can overflow Encoding. (devs.mak [1.74]: 2002/09/15
13:21:09 igor)
	- Fix (pdfwrite) : Completely removing the old PDF text code.
(devs.mak [1.75]: 2002/09/15 14:11:51 igor)
	- On case-insensitive file systems, sometimes PDF file detection
wasn't working. (toolbin/tests/gstestgs.py [1.14]: 2002/09/18 19:17:40 jack)
	- Typo in run_nightly. (toolbin/tests/run_nightly [1.7]: 2002/09/19
19:51:20 jack)
	- In dots mode, the DIFFER result had a spurious newline.
(toolbin/tests/gstestutils.py [1.5]: 2002/09/23 15:56:31 jack)
	- Fix : Providing a virtual path interface for computing glyph bbox
without allocating path segments. SourceForge bug "[ 605200 ] pdf_close
generates many path segments". (lib.mak [1.100]: 2002/09/23 16:38:28 igor)
	- Fix previous commit (marginal python skills)
(toolbin/tests/run_nightly [1.9]: 2002/09/26 16:28:15 ray)
	- Fix syntax errors and use actual paths for run_regression and
testdiff (toolbin/tests/run_nightly [1.11]: 2002/09/29 22:33:17 ray)
	- removes duplicate definition of gscspace_h. (lib.mak [1.102]:
2002/10/10 20:21:38 giles)
	- Remove psdrgb.dev and psdcmyk.dev from the MSVC makefile (these
crept in by mistake). (msvc32.mak [1.33]: 2002/10/11 15:39:35 ray)
	- remove the remainder of the gcc version check hack through the aux
dependency. This was missed in initial commit of that changed and prevented
normal running of the mcp-generation makefile. (macos-mcp.mak [1.10]:

Put in log files for the preparation steps: cvs update, make and install.
The cvs logs are cumulative (they can be truncated manually if desired).
These changes were in the actual running scripts until 9/18 when an update
overwrote these changes that were being tested, but were never committed.

The last fixup -- more bad python. (toolbin/tests/run_nightly [1.10]:
2002/09/26 16:33:01 ray)

Move the callback routine, which is used to translate a gs_separation_name
into a string pointer and a length, from the graphics state into the device
color structure. This is being done to make it available to the pdfwrite
device when handling DeviceN or Separation color spaces. (int.mak [1.84]:

Prune the dead 'begin' makefile target. This was supposedly removed in
release 5.20. (gs.mak [1.16]: 2002/10/09 22:13:17 giles)

Remove remaining references to ansi2knr.c. We no longer support building

Utilities

Fixes problems:
	- code cleanup in macos platform specific routines. (gp_mac.c [1.9]:
2002/09/17 00:09:26 giles)
	- the console stubs are no longer necessary for the macos build.

	- remove some compiler options that generated spurious warnings.
(macgenmcpxml.sh [1.5]: 2002/09/26 19:50:12 giles)

Apply casts to remove lots of warnings from MSVC 6. Update some Windows
color mapping functions for DeviceN. Change order of arguments for the
gs_pdf14_device_filter_push function and the calls to the device filter push
procedure to match the prototype. (gp_mswin.c [1.13], gp_ntfs.c [1.10],

Attached is a updated version of our code release of 4 October, 2002. As
before, the primary purpose of this release is to modify the manner in which
overprint information is passed to the overprint compositor device. This
resolves some difficulties seen when overprinting is used with the command
list device. This update incorporates the changes checked in by Dan on
October 4th. Since Dan's changes to gxcldev.h and gxclrast.c were identical
to ours, we have removed those two files from this release. Jan Modified
Files lib/gs_init.ps lib/pdf_draw.ps Change "DONTPS" flag to "DOPS", with
the logically inverted function: only if DOPS is defined will "PS" XObjects
be rendered. We believe this is the more appropriate default. lib/gs_dps.ps
lib/gs_img.ps src/gsdparams.c Modified the deviceinfo and image code to work
around a potentially improperly set ColorValues parameter. src/devs.mak
Updated dependency list for gdevscf.$(OBJ). src/gdevdflt.c 1. Added
initialization of the new color_info.opmode field to
gx_device_fill_in_procs. 2. In get_decode_color, added special case handling
for canonical 1-bit CMYK devices (e.g.: pkmraw). Previously the decode_color
method for this devices would default to gx_default_cmyk_decode_color, which
performed an CMYK ==> RGB ==> CMYK conversion. This conversion would
defeat overprinting if gray object was placed on top of a colored region.

src/gscspace.c src/gsovrc.c src/gxovrc.h src/gspcolor.c src/gsptype1.c
src/gsptype2.c src/gsstate.c src/gsstate.h src/gxcmap.c src/gxcspace.h
src/zcolor.c Modified the overprint code to, when necessary, pass overprint
mode information when setting the device color. This is necessary to
properly handle overprint mode when using the command list device. NB: This
change alters the meaning of the "effective_overprint_mode" field in the
imager state. src/gxdevcli.h Added the opmode and process_comps fields to
the gx_device_color_info structure. These are required by the new code that
passes overprint mode information when the device color is set.
src/gsdfilt.h Changed the prototype for the push method in the
gs_device_filter structure to match the actual implementation and usage of
this method (the third and fourth operands were reversed). src/gsimage.c
Modified gx_image_cleanup to check if penum->info field is null before
calling gx_image_end. This avoids a crash associated that can occur if an
image has zero height or width, as the image enumeration data structure will
have been released in such cases before gs_image_cleanup is called.
src/lib.mak Updated various dependency lists. src/gdevdevn.c src/gdevnfwd.c
src/gdevpdte.c src/gdevxcf.c src/gscrdp.c src/gsdfilt.c src/gsht.c
src/gsht1.c src/gswts.c src/gzht.h src/ialloc.c src/imain.c src/iscanbin.c
zfapi.c Installed some minor changes to quiet compiler warnings.
(gdevdevn.c [1.2], gdevxcf.c [1.3]: 2002/10/08 00:49:48 dan)

Adds DeviceCMY (-dMode=1) process color model to permute device.
(gdevperm.c [1.2]: 2002/10/08 16:49:59 raph)

Add a setup the shift and mask bits in ppm_open. This finishes initializing
the device as being "linear and separable". This is needed since the various
pxm devices are using the default color encode routine which needs the
linear and separable information. (gdevpbm.c [1.10]: 2002/10/09 02:34:11
dan)

PhotoShop PSD Driver. (gdevpsd.c [1.1]: 2002/10/12 11:43:21 jeong)

Removed logic for setting variable number of bits per component. This is not
supported on the xcf, spotrgb, or spotcmyk devices. (gdevdevn.c [1.3],
gdevxcf.c [1.4]: 2002/10/15 00:36:57 dan)

This is some clean up on the DeviceN devices: XCF, PSD, and spot devices. 1.
Ensuring that the process color model name is correct. 2. removing support
of SeparationColorNames from additive devices. 3. Finish removal of variable

PDF writer

Fixes problems:
	- Fix (pdfwrite): Virtual function same_font cannot work properly if
arguments have different representation (particularly for comparing an
original font with its stable copy). Due to it pdf_font_resource_t::Widths
mixed widths taken from fonts variations with different metrics. Entirely
changing the logics of creating font resources with new function
gs_copied_can_copy_glyphs. Source Forge bugs : #596394 (pdfwrite) Wrong

prevented compilation. (gdevpdfx.h [1.52]: 2002/09/09 16:08:19 giles)
	- Fix (pdfwrite) : Completing the logics of the Widths array
generation. Now the contents of Widths is taken from embedded font, but
widths for glyphs placement (Tj) are from original font. (gdevpdte.c [1.12],
gdevpdtt.c [1.10]: 2002/09/11 11:26:13 igor)

	- Fix (pdfwrite) : (1) gs_glyph_info_t::v was uninitialized if glyph
metrics is taken from the outline (thanks to Erik Strik for spotting it).
(2) Improving glyph placement. (3) A minor optimization and improving some
comments about glyph placament. (gdevpdte.c [1.13], gdevpdtt.c [1.12]:
2002/09/13 23:43:07 igor)
	- Fix (pdfwrite) : (1) The previous fix wrongly processed Metrics.
(2) TJ arguments were computed with accounting Tc taken from a desincronized
text state. (3) Type 42 missed side bearing. (4) An optimization reduces

	- Fix (pdfwrite) : (1) Unwinding the previous change for Tj
(gdevpdts.c). (2) sync_text_state now checks the ending position of the text
against the starting position of the text continuation (gdevpdts.c); (3)
font_orig_scale was erroneusely exchenged for original and copied fonts; (4)
Enhancing the hack in font_orig_scale with upside_down FontMatrix, (Source
Forge bug "[ 607480 ] 'Ghost' text appears"). (5) Enhancing
same_type1_hinting with fonts with nulls in Subrs (gxfcopy.c, test file of
#607480). Debugged with 0.pdf and 020-01.ps. (gdevpdts.c [1.14],
gdevpdtt.c [1.14]: 2002/09/14 19:29:30 igor)
	- Fix (pdfwrite) : Skipping Tj breaks being equal to Tc.
(gdevpdts.c [1.15]: 2002/09/14 20:27:07 igor)
	- Fix (pdfwrite) : (1) For better precision changing the internal
representation of Widths to double, and skipping small noise while writing
Tj. (2) Widths for Type 3 fonts were not computed (020-01.ps, 031-01.ps).

PDF Interpreter

Fixes problems:
	- Resolve Function parameters (optional as well as required) when
creating the PostScript Function dictionary for shadings. Fixes SourceForge
bug #609486. Fixes based on analysis and preliminary fix by Dan Coby.
(lib/pdf_draw.ps [1.52]: 2002/09/15 20:40:54 ray)
	- If the CIDCount for a font exceeded 32767, building the
CIDToGIDMap would exceed the maximum string length. Create an array of two
strings for this case. Also issue a warning if the CIDToGIDMap stream did
not contain enough characters for the CIDCount. SourceForge bug #611099 for
Artifex Customer #350. (lib/pdf_font.ps [1.45]: 2002/09/19 18:10:00 ray)
	- Insure that individual color name references are resolved in PDF
DeviceN colorspaces. (lib/pdf_draw.ps [1.53]: 2002/09/26 05:26:32 dan)
	- Fix to PDF interpreter : 1. Changing the logics of the True Type
cmap choice to comply with PDF spec. 2. Making the embedded font parser to
create a PS font independently on font resource options, so that the font
can associate with the font descriptor. 3. Avoiding the redundant parsing of
embedded fonts with removing the hack for SF bug "533467 Missing char on
test2a.pdf (regression)". 4. Removing the hack from buildTrueType because it
has no effect. 5. Widths and Encoding were ignored for embedded True Type
fonts. 6. Adding few warnings about PDF spec violations.
(lib/pdf_font.ps [1.46]: 2002/10/03 19:40:27 igor)
	- Ignore non-zero wy values to the d1 CharProcs operator in Type3
fonts. This is what Adobe Acrobat Readers do, and apparently Adobe Distiller
will write fonts with non-zero wy values even though the spec says "wy must
be zero". Fixes SourceForge bug #616692 for Artifex customer #561.

	- Keep pagedevice and device views of .LockSafetyParams correct even
after a 'restore' is used to unlock. The dictionary fed to the setpagedevice

  lib/gs_devn.ps
    Modified the cs_install procedure for DeviceN color spaces to
    support the component name array "[ All ]". The documentation
    indicates that this is not legal ("PDF Reference", 3rd. ed.,
    p. 206), but beginning with Acrobat 5, DeviceN color spaces with
    this component name array are handled in the same manner as
    Separation color spaces with the component name All. The modified
    code detects this component array and converts the operand color

The attached code release fixes a variety of memory handling problems
discovered by Dan's test with the memory validation enabled.

  2. Several problems noted with files 119-01.ps (panel 119-07) and
     119-28.ps (panel 119-31) were caused by a problem with the memory
     allocator used for the jpeg_compress_data structure used with the
     DCTEncode (JPEG) filter. This filter is used by the PDFwriter, the
     JPEG device drive, and as a filter accessible from PostScript.
     In the first two cases the jpeg_compress_data structure is allocated
     using the normal, gs_ref_memory_t structure. When used from
     PostScript, however, this structure is allocated using the
     gs_memory_default allocator (presumably because the jpeg library
     code is not set up to deal with save/restore).

     The gs_memory_default allocator is not a gs_ref_memory_t allocator,
     so it does not create the hidden obj_header_t structures preceding
     each allocated region. The garbage collector is dependent on these
     headers, hence the pointer enumeration routines in structure
     descriptors must not enumerate any pointers to memory allocated
     by non-gs_ref_memory_t headers.

     This creates a difficult problem for the pointer enumeration
     routine of the stream_DCT_state structure, whose data.compress field
     points to a jpeg_compress_data structure. This routine would have
     to determine which allocator was used for this structure before
     deciding whether or not to "enumerate" the data.compress pointer.
     In principle it has enough information to do this (the jpeg_memory
     field of the structure), but this seems like a overly complicated
     solution. Use of a stable gs_ref_memory_t allocator in place of
     the gs_memory_default allocator seems like a simpler solution.

  src/zfdcte.c
    Modified zDCTE to place the jpeg_compress_data structure into stable
    memory rather than use the gs_memory_default allocator.

Attached is a updated version of our code release of 4 October, 2002.

As before, the primary purpose of this release is to modify the manner
in which overprint information is passed to the overprint compositor
device.  This resolves some difficulties seen when overprinting is
used with the command list device.

This update incorporates the changes checked in by Dan on October 4th.
Since Dan's changes to gxcldev.h and gxclrast.c were identical to ours,
we have removed those two files from this release.

Modified Files

  lib/gs_init.ps
  lib/pdf_draw.ps
    Change "DONTPS" flag to "DOPS", with the logically inverted function:
    only if DOPS is defined will "PS" XObjects be rendered. We believe this
    is the more appropriate default.

  lib/gs_dps.ps
  lib/gs_img.ps
  src/gsdparams.c
    Modified the deviceinfo and image code to work around a potentially
    improperly set ColorValues parameter.

  src/devs.mak
    Updated dependency list for gdevscf.$(OBJ).

  src/gdevdflt.c
    1. Added initialization of the new color_info.opmode field to
       gx_device_fill_in_procs.
    2. In get_decode_color, added special case handling for canonical 1-bit
       CMYK devices (e.g.: pkmraw). Previously the decode_color method for
       this devices would default to gx_default_cmyk_decode_color, which
       performed an CMYK ==> RGB ==> CMYK conversion. This conversion would
       defeat overprinting if gray object was placed on top of a colored
       region.

  src/zcolor.c
    Modified the overprint code to, when necessary, pass overprint mode
    information when setting the device color. This is necessary to properly
    handle overprint mode when using the command list device.

    NB: This change alters the meaning of the "effective_overprint_mode" field
        in the imager state.

  src/ialloc.c
  src/imain.c
  src/iscanbin.c
  zfapi.c

The attached code release addresses a number of issues:

  1. Most of the code changes are required to turn off overprint mode when
     processing images, smooth shading fills (shfill operator), or
     when using PatternType 2 (smooth shading) patterns.

  2. A few other changes were required to correct improper updating of the
     overprint compositor information.

  3. The code has been modified to avoid the crash that was observed for
     the file 86554321.pdf on MSWindows XP systems.

  4. The command list playback code has been modified to handle filling of
     thin lines in a manner consistent with the noband case. This allows
     files such as mspro.pdf to be rendered consistently in the banded and
     noband case.

                                                                Jan


Modified Files:

  src/gscolor2.c
    1. Modified gs_setcolorspace to call gs_do_set_overprint rather than
       invoking the color space's set_overprint routine directly. This
       allows pattern color spaces to be handled (somewhat more) correctly.
    2. Modified gs_setcolor to update overprint information. This is
       necessary for pattern color spaces, where the color space to be used
       for overprint purposes may be part of the color.

  src/gscspace.c
    Modified gx_set_overprint_DeviceCMYK to use the effective_overprint_mode
    parameter in the image state (rather than the overprint_mode parameter
    itself). This is part of the change necessary to allow overprint mode to
    be turned off when a PatternType2 pattern is used as the current color.

  src/gsdevice.c
    Modified gs_set_device_no_init to call gs_do_set_overprint rather than
    invoking the color space's set_overprint routine directly.

  src/gsdps1.c
    Modified rectfill to use the effective_overprint_mode parameter in the
    imager state (rather than the overprint_mode parameter).

  src/gsovrc.c
    1. Fixed a bug in overprint_draw_thin_line: the third and fourth
       operands in the call to gx_default_draw_thin_line (the y coordinate
       of the first point and the x-coordinate of the second) were
       in reverse order. This caused random lines to appear on various
       overprint mode tests (e.g.: BEST99-00-Path.fh7.pdf,
       Testform.v1.0.2.pdf).
    2. Fixed typo in comment.
    3. Modified the fill_in_procs procedure to initialize the device color
       model information for the temporary device used in this routine.
       Though the color model information does not affect the output of
       the routine, reasonable values must be provided to avoid problems
       when gx_device_forward_fill_in_procs calls gx_device_fill_in_procs.
       This would cause certain systems to crash with files that involved
       overprint/overprint mode (e.g.: 86554321.pdf on MSWinXP/MSVC systems).
    4. Modified several checks that treated the separable_and_linear flag
       in the device color model information as a boolean to handle this
       parameter as an enumeration instead (since it is an enumeration).

  src/gsptype1.c
    Added gs_pattern1_set_color, the set_color method appropriate for
    PatternType 1 patterns. This method performs overprint updating at
    setcolor time, a requirement for patterns as the "colorspace" to be
    used for overprint purposes is determined (in part) by the current
    "color" (pattern).

  src/gsptype2.c
    Added gs_pattern2_set_color, the set_color method appropriate for
    PatternType 2 patterns.

  src/gsstate.c
    1. Changed the criterion used in gs_grestore_only to determine if the
       overprint compositor must be updated. Restoring the graphic state
       may change the current color, which in the case of patterns may
       change the "colorspace" to be used for overprint purposes. The code
       now properly handles this possibility.
    2. Added the gs_do_set_overprint routine, and modified various other
       routines that directly call the current color space's
       set_overprint method to call this procedure instead. The procedure
       implements the special handling required for pattern color spaces,
       where the current color may need to be considered when determining
       which color model components must be retained.
    3. Added code to initialize the effective_overprint_mode parameter in
       the imager state, and provided two external routines to manipulate
       this parameter. The first routine, gs_disable_effective_overprint_mode,
       sets the effective_overprint_mode parameter to false, irrespective
       of the setting of the overprint_mode parameter. The second,
       gs_reset_effective_overprint_mode, sets the effective_overprint_mode
       parameter to have the same value as the overprint_mode parameter.
       The effective_overprint_mode parameter is used to turn off
       overprint_mode when a PatternType 2 pattern is being used.

  src/gsstate.h
    Added prototypes for gs_do_set_overprint,
    gs_disable_effective_overprint_mode, and
    gs_reset_effective_overprint_mode.

  src/gxccache.c
    Modified gx_image_cached_char to invoke gx_set_dev_color before calling
    (non-standard) device fill_mask methods. This handles several
    situations in which a device color is not set when a cached character
    is to be imaged, in particular for the command list device.

  src/gxclpath.c
    Added a comment to indicate that, though the overprint and
    overprint_mode parameters are passed through the command list, they
    usually have no effect, as overprint is controlled by the compositor
    information that is (also) passed through the command list.

  src/gxclrast.c
    1. Added a comment to indicate that the overprint and overprint mode
       parameters passed through the command list usually have no effect.
    2. Added code to initialize the effective_parameter_mode field in the
       imager state (though this field is usually in-effective).
    3. Initialized the fill_zero_width field of the fill_params structure
       in clist_playback_band to have the same value as in the noband case.
       This parameter was previously always set to false, which led to
       dropped lines for some files (e.g.: mspro.pdf).

  src/gxistate.h
    Added the effective_overprint_mode parameter.

  src/gxpcolor.h
    Added a set_color method to the pattern method vector. This method
    performs any PatternType-specific actions necessary at setcolor
    time. For now, this just updates the overprint compositor as required.

Bump version numbers after 7.30 release. (gscdef.c [1.26]: 2002/09/12
09:52:20 giles)


  src/gxccache.c
    1. Fixed numerous problems with compress_alpha_bits and its invocation in
       gx_image_cached_char. The former procedure is called only if anti-
       aliasing (text alpha bits > 1) is called for a color that requires
       halftoning or for a device, such as pbmraw, that does not support the
       copy_alpha method. This happens infrequently, and the code was
       apparently never used.
    2. Moved the invocation of gs_set_dev_color to an earlier location in
       gx_image_cached_char, so that the device color will be set before
       any check is made to see if it is a pure color.

  src/gxclimag.c
    1. Added code in clist_fill_mask to return an error if the mask to be
       filled has depth > 1 and clist_disable_copy_alpha flag is set in the
       disable_mask field. The latter will be the case if the target device
       does not support copy alpha. The command list translates fill_mask
       calls into copy_alpha calls, which drives this requirement. By
       returning an error, the fall-back mechanism included in
       gx_image_cached_char (gxccache.c), which is the only client of the
       fill_mask method, can function properly.
    2. Also modified clist_fill_mask to check that the drawing color is
       pure if depth > 1 and use the default fill_mask method if this is
       not the case. (The copy_alpha call to which the command list code will
       translate the fill_mask works only for pure colors.) In addition, if
       the color is pure, the clist_fill_mask routine will now send commands
       to set color1 as well as transmit the device color; the code in
       clist_playback_band (gxclrast.c) assumes that all "copy_mono" and
       "copy_alpha" commands have set color1.

  src/gxclist.c
    Added code in clist_init_data to set the clist_disable_copy_alpha bit
    in the disable_mask field if the target device does not support the
    copy_alpha method. This must be done in this rather unintuitive location
    because it is impossible to tell if the target device supports copy_alpha
    until it has been made into a memory device (via the create_buf_device
    buffer device method).

  src/gxclist.h
    Defined the clist_disable_copy_alpha bit, which is used in the
    disable_mask field to indicate that the target device does not support
    the copy_alpha method.

  src/gxclrast.c
    Added include of gzht.h, to silence some compiler complaints.

  src/gxclrect.c
    Modified clist_copy_alpha to return an error if clist_disable_copy_alpha
    bit is set in the disable_mask field. This bit indicates that the target
    device does not support the copy_alpha method, so we might as well
    return an error now, while there is a chance the client might be able to
    do something about it.

The modification changes the way tile depth is encoded in the command
list as part of the cmd_opv_set_tile_size command.

Modified files:

  gxcldev.h
    Added the macros cmd_depth_to_code and cmd_code_to_depth. These allow
    encoding/decoding of the color model depth parameter (bits/pixel) in
    such a manner as to support depths up to 120 bits (depths > 15 bits
    must be a multiple of 8).

  gxclbits.c
    Modified cmd_store_tile_params to use the cmd_depth_to_code macro.

  gxclrast.c
    Modified read_set_tile_size to use the cmd_code_to_depth macro.

The attached code generalizes the sample_load_* and sample_store_* macros
in gsbitops.h to handle depths up to 64 bits. In addition to providing
64 bit versions of these macros, we also added the macros sample_load_any,
sample_load_next_any, and sample_store_next_any. These macros are intended
to be used in situations in which any supported depth may be used. All of
the invocations of the sample_load32, sample_load_next32, etc. macros have
been changed to invoke the *_any version of these macros instead. In
addition, a few minor changes have been made to silence compiler warning
messages.

Modified files:

  src/gdevalph.c
    Changed invocations of the sample_{load|store}_next32 macro to be
    invocations of sample_{load|store}_next_any instead. Also made various
    changes to allow the code to be compiled with the DeviceN system (the
    file has apparently not been compiled for some time).

  src/gdevdbit.c
    Made a couple of minor changes to silence compiler warning messages.

  src/gdevdgbr.c
    Changed invocations of the sample_{load|store}_next32 macro to be
    invocations of sample_{load|store}_next_any instead.

  src/gdevmpla.c
    Changed invocations of the sample_{load|store}_next32 macro to be
    invocations of sample_{load|store}_next_any instead.

  src/gsbitops.c
    Changed invocations of the sample_{load|store}_next32 macro to be
    invocations of sample_{load|store}_next_any instead. Also made the
    value being read/written be of type gx_color_index rather than
    type bits32.

  src/gsbitops.h
    Added 64-bit versions of the sample_load* and sample_store* macros.
    Also added *_any versions of these macros, to be used in situations
    where any supported color depth may be encountered.

  src/gxcindex.h
    Changed an invocation of the sample_store_next32 macro to be an
    invocation of sample_store_next_any instead. Also updated a comment.

src/gsht.c 1. Fixed a memory handling problem in gx_imager_dev_ht_install,
which could result in objects being freed multiple times. 2. Removed a
temporary hack in gx_imager_dev_ht_install that ensured that the halftone
cache always had at least one tile per level. This hack is no longer
necessary, as binary halftone device colors are now handled correctly.
(gsht.c [1.11]: 2002/09/21 07:08:27 dan)


Modified Files:

  src/gsmisc.c
    Fixed an apparently long-standing bug in ilog2. Due to a typo, this
    procedure returned 0 for any power of 16.

  src/gxoprect.c
    Fixed an uninitialized variable problem in
    gx_overprint_sep_fill_rectangle_1 and gx_overprint_sep_fill_rectangle_2.
(gsmisc.c [1.15], gxoprect.c [1.2]: 2002/09/23 01:21:02 dan; checkin for Jan)

Modified Files: src/gsht.c Modified the invocation of
gx_device_halftone_release in gx_ht_install to use the memory allocator
pointer stored in the device halftone, rather than the one stored in the
graphic state. src/gsimage.c Removed what appears to have been an errant
optimization in gx_image_cleanup. This procedure will now always invoke
gx_image_end, even if the image was not rendered (penum->dev == 0).
(gsht.c [1.12], gsimage.c [1.9]: 2002/09/23 21:36:31 dan)


The attached code release fixes a variety of memory handling problems
discovered by Dan's test with the memory validation enabled.

  1. Most of the problems with the FTS were accounted for by a relatively
     harmless dangling pointer problem for paths. In order to support the
     charpath operator, paths are normally constructed in stable memory
     (not subject to save/restore). However, clipping paths were
     constructed in normal memory. If the clippath operator was used to
     make the clipping path the current path, the top-level
     gx_path_segments would be in stable memory, while the rest of the
     path would be in normal memory. A restore operation could then
     leave dangling pointers.

     This is not normally a problem, because the grestore operation
     associated with the restore would clear the gx_path_segments
     structure. This only works on the graphic state stack, however;
     graphic state objects stored in VM would not be reset.

     This is harmful only in a very obscure case when the charpath operator
     is used on a user-defined font whose BuildGlyph procedure contains
     internal save/restore operators and which builds part of its
     output with the clippath operator. As far as we know, this has
     never occurred in practice.

  2. [...zDCTE stable memory...]

  3. If an overprint compositor was used with a banding device, the code
     in clist_playback_band was not cleaning up this compositor before
     exiting. This caused difficulty with the p2b-100.pdf file. This
     code has been modified to close the target device if this device
     does not match the original target device with which the routine
     was invoked.

  4. For historical reasons, the link between a halftone order and its
     tile cache is a bit peculiar. The order includes a pointer to the
     tile cache, and the tile cache keeps a copy of the order, which
     points to the same levels/bit data structure of the original order.
     Because of these two-way points, the order and its tile cache must
     use the same memory allocator to avoid dangling pointer problems.
     The code patch modifies gx_imager_dev_ht_install (gsht.c) to
     preserve this invariant. The change fixes another problem noted for
     p2b-100.pdf.

With these changes, we are able to run both the PS3 FTS and the full set
of pdf regression files using the '-Z@$?' switch with no reported problems.


                                                       Jan

Modified files:

  src/gspaint.c
  src/gspath.c
    In gs_strokepath and gs_clippath, cause the newly constructed path to
    use the memory allocator of the current path, rather than the memory
    of the current graphic state. This is no longer strictly necessary
    due to other changes that place path substructure completely in
    stable memory (see gxpath.c below).

  src/gxpath.c
    Modify path_allocs_segments, rc_free_path_segments_local,
    gx_path_add_lines_notes, and the path_alloc_segment macro to place
    the entire path substructure (from the gx_path_segments structure
    down) in stable memory. This is necessary to avoid dangling
    pointers, as a list of path segments may be attached to another path,
    parts of which were constructed with a different allocator.

  src/gsht1.c
    Removed obsolete code.

  src/gxclrast.c
    In clist_playback_band, close and discard the target device on
    completion of a band if it is not the same as the target device on
    entry.  This is necessary to remove an overprint compositor that
    may have been created in the course of the band.

  src/gsht.c
    In gx_imager_dev_ht_install, copy any halftone orders that were not
    allocated using the same allocator as used by the graphic state. This
    must be done to avoid dangling forward/back pointer between halftone
    orders and the associated tile caches.

Attached is a updated version of our code release of 4 October, 2002.

As before, the primary purpose of this release is to modify the manner
in which overprint information is passed to the overprint compositor
device.  This resolves some difficulties seen when overprinting is
used with the command list device.

This update incorporates the changes checked in by Dan on October 4th.
Since Dan's changes to gxcldev.h and gxclrast.c were identical to ours,
we have removed those two files from this release.

Modified Files

  lib/gs_init.ps
  lib/pdf_draw.ps
    Change "DONTPS" flag to "DOPS", with the logically inverted function:
    only if DOPS is defined will "PS" XObjects be rendered. We believe this
    is the more appropriate default.

  lib/gs_dps.ps
  lib/gs_img.ps
  src/gsdparams.c
    Modified the deviceinfo and image code to work around a potentially
    improperly set ColorValues parameter.

  src/devs.mak
    Updated dependency list for gdevscf.$(OBJ).

  src/gdevdflt.c
    1. Added initialization of the new color_info.opmode field to
       gx_device_fill_in_procs.
    2. In get_decode_color, added special case handling for canonical 1-bit
       CMYK devices (e.g.: pkmraw). Previously the decode_color method for
       this devices would default to gx_default_cmyk_decode_color, which
       performed an CMYK ==> RGB ==> CMYK conversion. This conversion would
       defeat overprinting if gray object was placed on top of a colored
       region.

  src/zcolor.c
    Modified the overprint code to, when necessary, pass overprint mode
    information when setting the device color. This is necessary to properly
    handle overprint mode when using the command list device.

    NB: This change alters the meaning of the "effective_overprint_mode" field
        in the imager state.

  src/gxdevcli.h
    Added the opmode and process_comps fields to the gx_device_color_info
    structure. These are required by the new code that passes overprint mode
    information when the device color is set.

  src/gsdfilt.h
    Changed the prototype for the push method in the gs_device_filter
    structure to match the actual implementation and usage of this method
    (the third and fourth operands were reversed).

  src/gsimage.c
    Modified gx_image_cleanup to check if penum->info field is null before
    calling gx_image_end. This avoids a crash associated that can occur if
    an image has zero height or width, as the image enumeration data structure
    will have been released in such cases before gs_image_cleanup is called.

    Updated various dependency lists.

Incompatible changes




A number of DeviceN changes can cause incompatibility. They are
summarized below.


* gx_color_index may now be 32 or 64 bits, determined at compile time.

* The gx_device_color_info field has been updated to include
  significantly more information about the encoding from colors in the
  process color model to gx_color_index colors. New fields include:
  polarity, gray_index, separable_and_linear, comp_shift, and comp_bits.
  Devices are strongly encouraged to set these new fields correctly.
  See gxdevcli.h for more information.

* Some existing device procedures for color mapping have changed.
  map_rgb_color now takes a cv[] array rather than separate red, green,
  and blue scalar color values, and similarly for map_cmyk_color.

* New device procedures: get_color_mapping_procs, get_color_comp_index,
  encode_color, decode_color. These device procedures are required for
  devices defining additional colorant planes, and may be desirable for
  finer control over color mapping. See gxdevcli.h and gxcmap.c for
  more information.

Procedures

Fixes problems:
	- Fixing syntax errors and potentially dangerous warnings with MSVC
after DeviceN merge. (lib.mak [1.91]: 2002/08/22 10:00:48 igor)
	- Logic to invoke banding was confused. Banding gets used when the
bandsize is too small for the full page raster. A bandsize of 10000 causes
banding. (toolbin/tests/gstestgs.py [1.12]: 2002/09/04 23:09:12 ray)
	- Provide an implementation of popen for Windows, to avoid the
broken implementation in MSVC++ 5 and 6. This allows pswrite to output to a
pipe on Windows. Fixes SourceForge bug #482038, pswrite does not write to
pipe. (winlib.mak [1.17]: 2002/09/05 08:34:00 ghostgum)
	- Fix : The "Fix: add missing header for isxdigit()." missed the
dependency update in devs.mak . (devs.mak [1.71]: 2002/09/05 08:50:53 igor)

Third and final commit of 7.22 release: bump version numbers to 7.23.
(version.mak [1.50]: 2002/08/07 06:58:53 raph)

Remove unused defines for the gtk client. (macos-fw.mak [1.6]: 2002/08/07

    Updated varius dependency lists.
(lib.mak [1.92]: 2002/08/26 23:00:07 dan)

Re corrected a problem with an illegal (from the point of view of MSVC)
period in a marcro name. Problem previously fixed by Igor. It came back in
the previous commit which came from ORIMP. (lib.mak [1.93]: 2002/08/26
23:02:24 dan)

Remove gdevht.c and gdevht.h. Also delete outdated references in lib.mak and
a few other files. (lib.mak [1.94]: 2002/09/04 06:36:36 dan)

Changes required for compilation on HPUX and Tru64. Add missing header in
lib.mak after gxdcolor.h added to gscolor3.c. Change dci_std_color_bits
macro to prevent a divide by zero, caused by the compiler not using shortcut
evaluation in an initializer. (lib.mak [1.95]: 2002/09/04 21:44:14 ghostgum)

Update versions, news and bug list for 7.30 alpha release.

Utilities

Fixes problems:
	- update MacOS build for changes in gs_abort(). (gp_mac.c [1.8]:
2002/08/27 20:27:26 giles)
	- Provide an implementation of popen for Windows, to avoid the
broken implementation in MSVC++ 5 and 6. This allows pswrite to output to a
pipe on Windows. Fixes SourceForge bug #482038, pswrite does not write to
pipe. (gp_mswin.c [1.12]: 2002/09/05 08:34:00 ghostgum)

DeviceN. (genconf.c [1.9]: 2002/08/22 07:12:28 henrys)

Code cleanup and warning fixes for macos platform-specific routines.
(gp_macio.c [1.8]: 2002/09/04 10:15:33 giles)


Drivers

Fixes problems:
	- FILE_IMPLEMENTATION=fd results in mixed use of unbuffered and
buffered output but the rest of the driver always uses buffered output.
Flushing the buffer in several places solves the problem. Fixes bug #427347.

PDF writer

Fixes problems:
	- Fix (pdfwrite): Widths for /.notdef was not cached, perhaps
Pscript.dll Version 5.0 generates an Encoding, in which /space is replaced
with /.notdef . Source Forge bug #590979 "Spaces drop out".

revision 1.9 . (gdevpdtf.c [1.13]: 2002/09/03 19:45:23 igor)
	- Fix (pdfwrite) : (1) Moving the temporary CID font wrapper from
stable to non-stable memory, because its descendent font is non-stable; (2)
Removing pdf_font_resource::glyphshow_font, because after (1) it points from
stable to non-stable memory. (3) representing the "glyphshow_font"

PDF Interpreter

Fixes problems:
	- Dereference indirect objects used as numbers in /Differences array
by pdfTeX-1.0-pdfcrypt. SourceForge bug #580873. Fix by Alex Cherepanov.
(lib/pdf_font.ps [1.42]: 2002/08/13 15:32:51 ray)
	- Extra 'ifelse' in a pdfformaterror case when the Widths array was
smaller than the character range. No SF bug, but fixes George.pdf for
Artifex customer #1 (their support ticket 1-2398). (lib/pdf_font.ps [1.43]:
2002/08/28 07:07:08 ray)
	- Improve accuracy of transparency detection logic. Fixes SF bug
#586595. (lib/pdf_main.ps [1.56]: 2002/08/28 17:34:16 raph)
	- Partial fix to 600855 to allow the pdfwrite (Distiller) to learn
the original font name as well as the unique font name generated by the PDF
interpreter when it copies a font and changes the Metrics and/or Encoding.
The FontName was made unique by appending a series of ? chars until a unique
name was generated. Now the suffix string itself is also defined in the
modified font dictionary with the /FontNameSuffix key. The pdfwrite text
handling needs to be modified to use this information.
(lib/pdf_font.ps [1.44]: 2002/08/29 06:26:22 ray)
	- Initialize graphic state (except CTM) before rendering annotation
appearance stream as stated in 7.4.4 of the PDF reference. Bug #576586,
customer #580. Fix by Alex Cherepanov. (lib/pdf_draw.ps [1.51]: 2002/09/01

	- Apparently filters that expect EOD throw an ioerror if no data is
received. Just processes without invoking any filter and everything works as
Adobe Acrobat Reader does. SourceForge bug #605236 for customer 561.

Interpreter

Fixes problems:
	- Fix (FAPI): Embedded Type 2 was misidentified as a non-embedded
font. (zfapi.c [1.24]: 2002/08/17 08:04:42 igor)
	- Fix (FAPI): Allowing servers to substitute glyph name for

(icstate.h [1.9], imainarg.c [1.22]: 2002/08/28 00:16:14 raph)
	- The technique used to prevent PageSize dimension of 0 silently set
the page size to 6 points whenever the dimension was < 6. Now either
dimension of 0 causes configurationerror from setpagedevice, but small
non-zero values are allowed if the InputAttributes allows it. Fixes

(lib/gs_setpd.ps [1.14], zmedia2.c [1.9]: 2002/08/28 14:32:28 ray)
	- Unbound null in the PostScript setup code (gs_init.ps) allowed
redef of /null to cause problems. Replace null with //null immediate name
binding to prevent this. Fixes SF bug #539239. Fix by Alex Cherepanov.
(lib/gs_init.ps [1.61]: 2002/08/28 16:20:19 ray)

	- Corrected the ID line. (Missing $ sign at the end.)
(zcolor3.c [1.2]: 2002/09/06 18:42:16 dan)
	- copy comment lines inside a procedure which require a scanner
refill to the operand stack, not the execution stack. Fixes SourceForge bug

This file was left out of the DeviceN checkin. (lib/gs_cspace.ps [1.1]:
2002/08/22 13:37:47 henrys)

This file was evidently dropped from the DeviceN merge. This eliminates a
loop that can occur in non-sepqxd2distiller.pdf. lib/gs_icc.ps Modified the
cs_substitute routine to suppress color space substitution if the resulting
color space cannot be an Alternate color space for an ICCBased color space.
This situation arises with some frequency in PDF files.

gs_text_update_dev_color, to update the color used for drawing text if this
changes during a text operation (e.g.: due to the action of a kshow or cshow
procedure). src/zchar.c Modified op_show_continue to call
gs_text_update_dev_color in case a cshow or kshow procedure changed the
current color (strictly speaking, this is only a problem with kshow).

    the former change.

Merge page device Policies from the driver and defaults during the device

From ORIMP: Modified files: src/gsht.c: In gx_imager_dev_ht_install, the
comp_number field in the entries for the newly allocated components_array
was improperly assigned, due to a typo. Later code checks if the comp_number
value matches the component index and, if not, uses the default halftone
order for this component. This would cause a typical 4-color device to
always use the default halftone component (and leak memory). As part of the
same fix, some redundant code in gx_imager_dev_ht_install has been removed,
and the code that updates the "used_default" variable in this procedure has
been corrected. (gsht.c [1.7]: 2002/08/23 07:43:30 dan)

Modified files: src/gstext.h src/gstext.c Added the routine
gs_text_update_dev_color, to update the color used for drawing text if this
changes during a text operation (e.g.: due to the action of a kshow or cshow
procedure). src/zchar.c Modified op_show_continue to call
gs_text_update_dev_color in case a cshow or kshow procedure changed the
current color (strictly speaking, this is only a problem with kshow).
(gstext.c [1.10], gstext.h [1.7]: 2002/08/26 22:51:53 dan)

Modified files:

  src/gdevdbit.c:
    Changed gx_default_fill_mask to use the fill_masked routine of the
    device color. This avoids an instance in which a possibly
    uninitialized halftone tile is used for drawing. It also makes the
    code considerably cleaner.

  src/gscdefs.h
    Re-installed the definition of extern_gs_find_compositor, which had
    in-advertently been lost in a recent code merge.

  src/gsdcolor.h
    Added the colors.binary.b_level field to the gx_device_color_saved
    structure. Also added a comment explaining why this structure is
    used rather than the gx_device_color structure itself.

  src/gsht.c
    This file should be identical to the version released on Aug. 22nd.
    We are releasing again here just to guard against this code being
    committed without the former change.

  src/gsht1.c
    Modified the check for "binaryness" of a device color model in
    gs_sethalftone_try_wts to handle cases in which not all of the depth
    bits are used.

  src/gstext.c,
  src/gxtext.h
  src/zchar.c
    These files are identical to the set released on Aug. 23rd (the fix
    for color changes in a kshow procedure). We are releasing them again
    here to make certain the rest of this code is not committed without
    the former change.

  src/gxacpath.c
    Modified gx_cpath_accum_end to set the new bbox_accurate field rather
    than the bbox_set field. This avoids overloading the bbox_set field
    in a way that can lead to inconsistent output when the setbbox
    operator is used with a path.

  src/gxcht.c
  src/gxht.c
  src/gxdcolor.c
  src/gxdcolor.h
    Modified the "write" methods for various color spaces so that their
    return value can indicate that the operand and last transmitted
    colors are the same. Also fixed various bugs uncovered when the
    modular device color serialization/de-serialization was first used.
    The changes to gxdcolor.h involve only comments.

  src/gxcldev.h
    1. Added a saved device color (gx_device_color_saved) to the band
       state structure.
    2. Removed the (long since unnecessary) type operand from the
       cmd_put_halftone procedure.
    3. Commented out some now obsolete command codes.

  src/gxclimag.c
    1. Modified clist_fill_mask to work with the new, modular drawing
       color serialization/de-serialization routines.
    2. Rewrote cmd_put_halftone as required by the new mechanism for
       serializing/de-serializing device halftones.
    3. Modified various invocations of cmd_put_halftone to discard the
       the type operand.

    Note: The existing code impose a requirement that image objects that
          used a device color (e.g.: image masks) would only be passed
          through the command list if that color is pure. We do not
          know why this limitation was necessary, and suspect it is no
          longer necessary, but we have left it in place for now.

  src/gxclist.c
    Added gxdcolor.h to the included file list.

  src/gxclpath.c
    1. Rewrote cmd_put_drawing_color to use the new mechanism for
       serialization/de-serialization of device colors.
    2. Removed the device color type information from the stroke/
       fill/polyfill commands.
    3. Modified cmd_put_path so that "moveto closepath" is not
       passed through the command list as just "moveto".

  src/gxclpath.h
    1. Added the cmd_opv_ext_put_ht_seg, to allow device halftones to be
       split across multiple command buffers. Also added the macro
       cbuf_ht_seg_max_size, to indicate the largest halftone segment to
       be put in a single command buffer.
    2. Commented out some now obsolete command codes.
  src/gxclrast.c
    1. Modified the code to read device halftones and device colors to
       use the new serialization/de-serialization methods for these
       structures.
    2. Modified various locations in which partial/temporary device
       colors are used to use the current color for the band.
    3. Removed code for the various stroke/fill/polyfill commands that
       encode device color type as part of the command.
    4. Added code to save the current color when a pure color must be
       set to generate a clip region using the fill procedure.
    5. Modified the clip path reading code to flatten the clip path
       before passing it to the fill operation. This is necessary to
       ensure consistent results between the banded and non-banded
       cases (the non-banded case also flattens a clip path before
       passing it to the fill operation).

  src/gxdhtserial.c
    1. Updated gx_ht_read_tf and gx_ht_read_and_install to properly
       use the reference count in a transfer function.
    2. Fixed various other errors discovered when this code was first
       used.

  src/gxdhtserial.h
    Fixed typo.

  src/gxpath.c
    Initialize the new bbox_accurate field of the gx_path structure to
    false in gx_path_init_contents.

  src/gxpath2.c
    Modified gx_path_bbox to use the bbox_accurate rather than bbox_set
    field to determine if the bounding box of a path needs to be
    explicitly calculated. If bbox_set is true, the bounding box
    in the bbox field will contain the current path, but may be larger
    than necessary. Due to a problem in the clip/fill code, the larger
    bounding box may generate slightly inconsistent results.

  src/gzpath.h
    Added the bbox_accurate field to the gx_path_s structure. This field
    is used by the clip accumulator device, which avoids the need to
    overload the bbox_set field (which is also used by the setbbox
    operator).

  src/lib.mak
    Updated varius dependency lists.

Another fix of a problem that had been previously fixed and lost due to a
commit of files from ORIMP. MSVC will not accept { } for a structure
initializer. Added a zero to keep MSVC happy. Problem previously fixed by
Igor. (gsht1.c [1.10]: 2002/08/26 23:07:00 dan)

We have traced the difficulties with multiple-band processing in the code
we released on Aug. 26 to two problems:

  1. The halftone phase information is not adjusted for bands that
     start at locations other than the top of the page.

  2. The "moveto closepath" style of degenerate path, which our code
     allows to be passed through the band list, is used in the path
     encoding code to indicate that a path lies entirely outside the
     current band (i.e.: all of the path operators between the initial
     moveto and the final closepath have been skipped because they are
     outside of the band). This resulted in the code passing isolated
     "closepath" segments through the command list, which much confused
     the band list renderer.

The attached code release fixes both of these problems, and a couple of
other more minor issues we discovered. With this change, our system has
identical output for the banded and unbanded case for the pkmraw device
at 300 dpi, for all but one FTS file (027-09.ps). In that one case, the
banded and unbanded output are visually identical, so the output difference
may not be significant. We will look into this situation, and test some
of the other devices in the next day or so.

As best we can tell, halftone phase adjustment has never been correctly
implemented for the command list device. The pre-DeviceN code handles
binary halftone colors properly, but does not set the phase for general
colored halftones. General colored halftones are much more common in the
DeviceN code, which probably is the reason Dan first noticed the problem
with FTS file 245-07.ps (and others) with the DeviceN code.

                                                         Jan

Modified Files:

  src/gsht.c
    Modified the code that calculates the lcm_height field of a device
    halftone in gx_imager_dev_ht_install to use the full_height rather
    than the height of a halftone order. This typo was introduced sometime
    during the DeviceN development; the pre-DeviceN code was correct.

  src/gsptype1.c
  src/gsptype2.c
  src/gxwts.c
    Added the "get_phase" method to various gx_device_color_type_t
    instances.
  src/gxcht.c
  src/gxht.c
    Added the "get_phase" method to a pair of gx_device_color_type_t
    instances. Also modified the "write" and "read" methods of these
    structures to ignore halftone phase information. This information
    must be passed to and be directly handled by the command list
    writer code, so that the command list renderer code may correct it
    for the band starting coordinates.

  src/gxclpath.c
    1. Modified cmd_put_drawing_color to directly handle halftone phase
       information, using the new "get_phase" method of device colors.
       The passing of this information must be perfomed at the command
       list level, so that the command list renderer can correct the
       phase for the starting point of the band.
    2. Also in cmd_put_drawing_color, "unset" the saved color information
       if the halftone id does not match the most recently set halftone,
       rather than setting the saved color pointer to 0.
    3. In cmd_put_path, when processing a segment containing a
       moveto followed by a closepath, check if the moveto was to a point
       outside of the current band, and discard the closepath if this
       is the case. This is necessary to avoid inserting isolated
       closepath segments into the command list.

  src/gxclrast.c
    Added code to initialize the dev_color variable to clist_playback_band
    to "no color".

  src/gxdcolor.c
  src/gxdcolor.h
    Added the "get_phase" method to the gx_device_color_type_t structure,
    and installed this method in various instances of the structure. Also
    provided the two canonical implementations of this method.
(gsht.c [1.9], gsptype1.c [1.9], gsptype2.c [1.9], gxcht.c [1.10],

The two files were missed in earlier commits. Missing from the 8-28-02
commit form ORIMP. src/gxdcolor.c Added the "get_phase" method to the
gx_device_color_type_t structure, and installed this method in various
instances of the structure. Also provided the two canonical implementations
of this method. Missing from the 8-26-02 commit from ORIMP.
src/gxdhtserial.c 1. Updated gx_ht_read_tf and gx_ht_read_and_install to
properly use the reference count in a transfer function. 2. Fixed various
other errors discovered when this code was first used. (gxdcolor.h [1.9],
gxdhtserial.c [1.2]: 2002/08/29 00:11:30 dan)

The attached code fixes a minor problem introduced in our release
of August 26th. That release changed the behavior of the gx_path_bbox
procedure (gxpath2.c) so as to make the banding and non-banding cases
consistent. In the process we inadvertently also changed the behavior
of the pathbbox operator. This fix restores the proper behavior of
that operator.

Also included is a modified version of gsht.c for interim use. This is
not intended for final release. The gx_imager_dev_ht_install routine
is modified in this code to ensure that the halftone caches are also
made large enough to provide (at least) one tile per level. Doing so
avoids the cache overwrite bug that Dan has described, which avoids
many spurious differences in the regression test. Once Dan's fix for
the handling of the halftone tile in binary halftone colors is
installed, this version of gsht.c may be discarded.

Modified files:
 src/gspath1.c
    Modified gs_upathbbox to call gx_path_bbox_set rather than
    gx_path_bbox. The former will return the bounding box set via the
    setbbox operator, if that operator has been used for the current
    path; otherwise it will return the actual path bounding box. The
    latter will always return the actual path bounding box.

  src/gxpath.h
  src/gxpath2.c
    Added the gx_path_bbox_set procedure, which will return the
    bounding box set by the setbbox operator if that operator has been
    used for the current path.

Temporary Files:

  src/gsht.c
    Modified the gx_imager_dev_ht_install procedure to always allocate
    caches large enough to provide (at least) one tile per level. This
    is a temporary hack to avoid a bug with the handling of tiles for
    binary halftone colors. It is not intended for the final release.

This is a repeat of an earlier commit that was backed out. Its back. Split
the binary half tone cache initialization into two pieces. The halftone
cache is now initialized just prior to being used in the various halftone
render routines. This was done to prevent a problem with cache conflicts. If
the half tone cache is not large enough for a separate tile for each level
then there could be a problem if two different device colors used the same
cache entry but with different level values. (gxht.c [1.11],
gximono.c [1.8]: 2002/08/30 04:39:10 dan)

A line was left out of the previous commit. This is part of the splitting of
the load the binary halftone cache until it is ready to be used.
(gxht.c [1.12]: 2002/08/30 06:19:54 dan)

Modified File: src/gxdevndi.c Modified gx_render_device_DeviceN to always
perform the conversion from color component intensity values to halftone
levels in an additive sense, if the gray_colorspace operand is true. This is
necessary for compatibility with the pre-DeviceN code. (gxdevndi.c [1.2]:
2002/09/03 02:58:48 dan)

Remove gdevht.c and gdevht.h. Also delete outdated references in lib.mak and

Changes required for compilation on HPUX and Tru64. Add missing header in
lib.mak after gxdcolor.h added to gscolor3.c. Change dci_std_color_bits
macro to prevent a divide by zero, caused by the compiler not using shortcut
evaluation in an initializer. (gxdevcli.h [1.12]: 2002/09/04 21:44:14

            use of the (no longer initialized) default order.

        Attached is the second installment of the code for modular serialization
        of device color in the command list. This release includes all of the
        necessary support code, but this code has not yet been hooked into the
        command list devices (writer and reader). That should be accomplished in
        a few days.
        
                                                                      Jan
        
        
        Files Added:
        
          gsserial.c        These two files provide a extended and public version
          gsserial.h        of the little-endian integer encoding used by the
                            command list. Since serialization can occur
                            outside of the command list, it is reasonable to have
                            this facility become a general utility. (For now,
                            at least, the command-list specific version of this
                            encoding remains as well.)
        
                            gsserial.c includes a unit-test.
        
        
          gxdhtserial.c     Code to serialize device halftones. These are serialized
          gxdhtserial.h     as a unit, rather than using separate commands for
                            separate pieces.
        
        
        Files Modified:
        
          gsdcolor.h        Removed the no longer used screens field from the wts
                            field of the colors union of the gx_device_color
                            structure.
        
                            Added the gx_device_color_saved structure, which may be
                            used by the command list device to retain information
                            about the last device color placed in a band. Using this
                            information can reduce the size of the newly encoded
                            color.
        
          gxdcolor.h        Added methods to the gx_device_color_type_t method
                            vector to support serialization of device colors. The
                            new methods are:
        
                              save_dc
                                Create a "saved" version of the device color. The
                                saved version contains information about the
                                device color, but does not include any pointers.
                                It can be used to reduce the amount of information
                                encoded with a device color.
        
                              get_dev_halftone
                                Return the device halftone used by a device color
                                (or a null pointer if no device halftone is used).
        
                              write
                                Serialize the device color.
        
                              read
                                Reconstruct the device color from its serial
                                representation.
        
                            Also added prototypes for two utilities to be used
                            when serializing device colors: gx_dc_write_color
                            and gx_dc_read_color. These work on color indices.
        
          gxclpath.h        Added the codes for cmd_opv_ext_put_halftone and
                            cmd_opv_ext_put_drawing_color.
        
          gxpcolor.h        Added prototypes for gx_dc_pattern_save_dc,
                            gx_pattern_dc_write, and gx_dc_pattern_read. Since
                            patterns cannot be passed through the command list,
                            all of these just return errors.
        
          gsptype1.c        Added stubs for the new device color methods. The
          gsptype2.c        get_dev_halftone method is supported to the extent
                            possible; it cannot be supported for color
                            PatternType 1 patterns as their PaintProc procedures
                            may use multiple patterns.
        
          gxcht.c           Added support for the new device color methods for
                            general (colored halftone ) device colors, including
                            full serialization support.
        
          gxht.c            Added support for the new device color methods for
                            binary halftone device colors, including full
                            serialization support.
        
          gxdcolor.c        Added support for the new device color methods for
                            the "no color", transparent, and pure device colors,
                            including serialization support. Also added the two
                            utility routines gx_dc_write_color and
                            gx_dc_read_color, which work on color indices.
        
          gxwts.c           Added stubs to support the new device color methods.
                            Also corrected a few minor compiler complaints.
        
          lib.mak           Added targets for gsserial.$(OBJ) and
                            gxdhtserial.$(OBJ). Also updated some dependency
                            lists.
        
        * zcolor.c [1.8] (+1 -2):
        Modified Files: (jan)
        
          lib/gs_cspace.ps
            Added _setcolorspace_nosub, a variation of the setcolorspace operation that
            avoids color space substitution. This is required for ICCBased color spaces,
            as they may be used to substitute for a device-specific color space, but
            use that same device-specific color space as an alternative space. If the
            alternative space was used (or even if it wasn't, in the prior code), an
            infinite loop would result (the eventual error is execstackoverflow).
        
          lib/gs_icc.ps
            Modified the cs_install routine for ICCBased color spaces to use the new
            _setcolorspace_nosub procedure.
        
          lib/pdf_draw.ps
            Removed the color substitution scheme used by resolvecolorspace. This has
            been superseded by the PostScript-based scheme.
        
          lib/pdf_main.ps
            Implemented color space substitution using PostScript's method. This works
            for all color spaces and, with the above noted modifications to
            gs_cspace.ps and gs_icc.ps, avoids infinite-loop problems. The
            earlier code did not implement color space substitution for
            DeviceCMYK (the code was just missing) and in rare cases could
            suffer from infinite loops.
        
          src/zcolor.c
            Correct a typo: the .setdevcspace operator was included twice in the
            zcolor_op_defs array.

        * gzht.h [1.7] (+4 -6), gxclrast.c [1.19] (+9 -11), gswts.h [1.2] (+7 -1), 
        gswts.c [1.2] (+13 -1), gshtx.c [1.9] (+4 -2), gshtscr.c [1.6] (+5 -2), 
        gsht1.c [1.9] (+31 -14), gsht.c [1.15] (+556 -190):
        
        This is the first part of the code we are providing to allow device
        colors to be passed through the command list in a modular manner. The
        rest of the code should be released within a couple of days. We are
        providing this code first because we need to fix these leaks in order
        for the rest of the code to function correctly, but these fixes are
        otherwise independent of that code.
        
          src/gsht.c:
        
            a. Added a (moderately hack-ish) mechanism to allow halftone
               components to share well-tempered screens. This mechanism uses the
               width field of the halftone component, which is nominally not used
               for well-tempered screens, to indicate which component "owns" the
               screen and can release it.
        
            b. Modified gx_ht_alloc_ht_order and gx_ht_copy_ht_order to handle well-
               tempered screens, which do not have levels or bid_data arrays.
        
            c. Created gx_ht_move_ht_order, an analog to gx_ht_copy_ht_order, that
               assumes ownership of the structure's reference by a source halftone
               order rather than copying them.
        
            d. Modified gx_ht_order_release to handle well-tempered screen
               component orders, and to decrement the transfer function
               referenced by a halftone order (as opposed to blindly releasing
               it).
        
            e. Completely re-wrote gx_imager_dev_ht_install, to fix various memory
               leaks and better handle well-tempered screens. See the comments
               in the procedure for additional information.
        
            f. Modified gx_ht_install to take ownership of all structures referenced
               by the operand device halftone, if it returns successfully. This
               matches the behavior of the pre-DeviceN code and is required by
               various clients to avoid memory leaks. Any referenced structures
               that are not required by the device halftone in the imager state
               will be released (again, only on successful completion).
        
            g. Modified gx_imager_set_effective_xfer to ignore the "default"
               order in a device halftone. This order is not used for device
               halftones installed in the imager state, and
               gx_imager_set_effective_xfer should only be called for device
               halftones installed in the imager state.
        
          src/gsht1.c:
            a. Modified gs_sethalftone_allocated to release any unused parts
               of the device halftone in the event that gx_ht_install returns
               with an error code.
        
            b. Modified gs_sethalftone_prepare to not allocate a cache for
               (traditional) halftone orders.
        
            c. Modified process_transfer to set a reference count of 1 in the
               transfer functions. This is appropriate, as the routine
               sets a reference to these structures (in the halftone component
               order).
        
            d. Simplified the check for bi-level device in gs_sethalftone_try_wts.
        
            e. Used gs_alloc_struct_array in place of malloc for allocating the
               component order array in gs_sethalftone_try_wts.
        
            f. Set the num_bits and num_levels values in well-tempered screening
               halftone orders to 0. This setting is required to allow them to
               be correctly handled by gx_ht_copy_ht_order.
        
            g. Added processing of halftones to gx_sethalftone_try_wts.
        
        
          src/gshtscr.c:
            Modified gs_screen_install to discard any structures referenced by
            a device halftone if gx_ht_install returns an error code.
        
          src/gshtx.c
            Modified gs_ht_install to discard any structures referenced by
            a device halftone if gx_ht_install returns an error code.
        
          src/gswts.c
            Added the procedures gs_wts_free_enum and gs_wts_free_screen, to
            free gs_wts_screen_enum_t and wts_screen_t structures.
        
          src/gswts.h
            Added prototypes for the procedures gs_wts_free_enum and
            gs_wts_free_screen. These are used by the device halftone
            code to free gs_wts_screen_enum_t and wts_screen_t structures.
        
          src/gxclrast.c
            Added code in read_set_ht_data to discard just the allocated
            halftone components array, but not any of the structures
            it references, after gx_imager_dev_ht_install returns. This is
            necessary as gx_imager_dev_ht_install will always copy this
            structure, and cannot release the original.
        
            NB: This is an interim change. The mechanism by which halftones
                are passed through the command list will change shortly.
        
          src/gzht.h
            Modified the prototypes for gx_imager_dev_ht_install and
            gx_ht_install to remove the const qualifier for the device
            halftone operand.

        The data section of the gray transfer component (from the setcolortransfer
        operator) and the 'default_comp' were not both being updated properly.
        This resulted in gray transfer functions not being transfered properly
        through the clist.  The fix involves simply removing the 'default_comp'
        and using the gray component for the default and for the settransfer
        operator.

        routine were special casing 1, 3, and 4 components cases and assuming
        that there were Gray, RGB, and CMYK.  This did not work for DeviceN
        colorspaces.  The fix involves using the colorspace remap_color
        routine instead of going directly to the cmap_procs.  This should be
        slightly slower (but will work in all cases).

        (Jan) Implements the overprint and overprint mode features for the
        PostScript and PDF writer devices. These devices have supported the
        overprint feature for some time. The modifications allow them to
        intercept and discard the create_compositor invocation for the
        overprint compositor, as they don't need the compositor and already
        access overprint information from the imager state.
        
        Note: This set of changes is quite simple, but we have no easy way to
              test the result. Hence, while we believe it very unlikely the
              changes will cause discrepancies, we have not actually tested
              them (other than to verify compilation).
        
        Modified files:
        
          src/devs.mak
            Updated dependency list for gdevpsdu.$(OBJ).
        
          src/gdevpdf.c
            Added the methods psdf_get_bits, psdf_get_bits_rectangle, and
            psdf_create_compositor to the method vector initialization of the
            gs_pdfwrite_device.
        
          src/gdevps.c
            Added the methods psdf_get_bits, psdf_get_bits_rectangle, and
            psdf_create_compositor to the method vector initialization of the
            gs_pswrite_device and gs_epswrite_device.
        
          src/gdevpsdf.h
            Added prototypes for the psdf_get_bits, psdf_get_bits_rectangle,
            and psdf_create_compositor procedures.
        
          src/gdevpsdu.c
            Added the psdf_get_bits, psdf_get_bits_rectangle, and
            psdf_create_compositor procedures. The first of these just returns
            an unregistered error. The prior code also generated an error if
            these methods were called, but via a much more obscure and round-
            about route. The psdf_create_compositor procedure recognizes and
            discards invocations of the create_compositor method for the overprint
            compositor. The PostScript and PDF writers do not need this compositor
            to support overprint, and would fail if it were present as it
            requires support for the get_bits/get_bits_rectangle methods.

        Patch from Russel Lang  (gsview@ghostgum.com.au)
        
        Anti-aliasing for CMYK devices did not work because
        gx_default_copy_alpha converted the new and existing pixel
        values to RGB, merged them then remapped the result. This
        patch uses decode_color on the two pixels, merges the pixel
        color values individually, then uses encode_color on the
        result.
        
        To avoid flashes of incorrect colour begin displayed when
        the display device size is changed, the display device
        erases the page to white immediately after bitmap
        allocation. Actually, it was erasing the colour to
        RGB(1.0,1.0.1.0) by calling map_rgb_color, which actually
        calls encode_color which is expecting CMYK as input.  This
        resulted in a black background. This patch changes the code
        to use encode_color with appropriate values for DeviceGray,
        DeviceRGB or DeviceCMYK.
        
        The display device did not work with CMYK anti-aliasing
        because the decode_color procedure was decoding to RGB, not
        CMYK.  This patch adds new cmyk_[18]bit_map_color_cmyk
        functions for decode_color.

        * gsdps1.c [1.3] (+3 -2):
        The following should be prominently posted in full view of all
        software engineers:
        
          ***Do not use caches to hold unreplaceable data***
        
        Failure to follow that rule of good programming is the heart of the
        problem with FTS panel 245-04 (file 245-01.ps).
        
        The immediate cause of the problem is the optimization put in the
        setcolorspace code to avoid repeatedly setting the same color space.
        The steps that lead to the error are the following:
        
          1. The job sets a CIEBasedABC color space as the current color
             space. The white and black point information from the color
             space dictionary is combined with the white and black point
             information in the color rendering dictionary to sample the
             TransformPQR procedures in that dictionary. The resulting
             data is placed in the joint CIE cache. All of this activity
             ends with an execution of the internal operator cie_tpqr_finish
             (zcrd.c). This operator has two side-effects:
        
                 The TransformPQR data structure in the cie_render structure
                 of the current state is set to TransformPQR_from_cache, which
                 indicates that the PQR phase of the CIE color mapping (the
                 white point point adjustment) is to be done via the joint CIE
                 cache.
        
                 The gs_cie_cs_complete procedure is invoked with the "init"
                 argument set to false, indicating that no further
                 initialization is required for the joint CIE caches. This
                 causes the status flag in those caches to be set to
                 CIE_JC_STATUS_INITED, indicating that the caches are ready
                 to use.
        
          2. The job calls gsave. Since the joint CIE caches can be shared by
             multiple graphic states, the cache reference count is incremented.
        
          3. The job sets a pattern color space, whose base color space is the
             current (CIEBasedABC) color space.
        
             The PostScript interpreter in Ghostscript uses the convention that
             a base or alternative color space will always be set as the current
             color space immediately before the enclosing color space is set.
             The cs_install procedure for the pattern color space
             (lib/gs_patrn.ps) invokes setcolorspace on the base space. Because
             this is already the current color space, nothing happens.
        
          4. Immediately afterwards, the cs_install procedure invokes the
             .setpatternspace operator on the enclosing pattern color space.
             Through a couple of layers, this will invoke the "install_cspace"
             method for pattern color spaces, the gx_install_Pattern
             (gspcolor.c). This will in turn invoke the "install_cspace" method
             for the base color space, in this case gx_install_CIE.
        
          5. Through a few additional layers, gx_install_CIE will also call
             gs_cie_cs_complete (see (1) above), but this time the "init"
             variable will be set to true, indicating that additional
             initialization is required.
        
             gs_cie_cs_complete will invoke gx_currentciecaches, whose purpose
             is to make sure that new copies of the joint CIE cache is created
             when necessary. Since the reference count on the existing cache is
             larger than 1 (see (2) above), a unique copy of the cache is created
             and is marked as invalid.
        
          6. Subsequently, when drawing is attempted in the base color (the
             pattern has PaintType 2), the code will note that the cache is
             not yet valid and invoke cie_joint_caches_init (gscie.c). This
             routine can do nothing, however, because the TransformPQR structure
             for the cie_render structure in the graphic state is set to
             TransformPQR_from_cache, indicating that the only data available
             for the TransformPQR procedure is in the (now invalidated) cache.
        
             As a fall-back, the CIE color is mapped to RGB by setting all
             components to 0, which yields the black output.
        
        The proper fix for this problem is re-designing both the CIE color space
        and the color rendering structures so that they retain enough information
        to regenerate the joint CIE cache when necessary. Since that is a big
        change, the attached modifications take the more modest approach of adding
        a "forcesetcolorspace" operator, which will set a color space even if it
        is identical to the current color space.
        
        Also included in the set of changes is a minor modification to gs_rectfill
        (gsdps1.c) that suppresses direct access to the device's fill_rectangle
        procedure if both overprint and overprint mode are true. Since
        overprintmode must be applied prior to halftoning, the code must be forced
        through one of the higher-level methods which include the pre-halftoned
        device color information.
        
        Modified files:
        
          lib/gs_cspace.ps
            Added the _setcolorspace procedure, which accepts both a boolean and
            a color space dictionary. If the boolean is true, the color space
            will not be set if it is the same as the current color space (via a
            conservative evaluation).
        
            The setcolorspace pseudo-operator now invokes _setcolorspace with the
            boolean operand set to true. A new operator, forcesetcolorspace,
            invokes _setcolorspace with boolean set to false.
        
          lib/gs_devn.ps
          lib/gs_icc.ps
          lib/gs_indxd.ps
          lib/gs_patrn.ps
          lib/gs_sepr.ps
            Replaced setcolorspace with forcesetcolorspace when setting a base or
            alternative color space. This is necessary due to some problems in the
            handling of the the joint CIE cache in the graphic library.
        
          src/gsdps1.c
            Modify gs_rectfill to suppress direct access of a device's
            fill_rectangle method if both overprint and overprint mode are set
            to true. This is required to make sure the overprint compositor has
            access to pre-halftoned device color information with which to
            implement overprint mode.

        Split the half tone cache initialization into two pieces.  The halftone
        cache is now initialized just prior to being used in the various
        halftone render routines.  This was doe to prevent a problem with cache
        conflicts.  If the half tone cache is not large enough for a separate
        tile for each level then there could be a problem if two different
        device colors used the same cache entry but with different level values.

        This commit is to remove the change from yesterday.  That commit has
        some serious flaws.  It fixed a small problem by creating some larger ones.
        
        There is still a flaw in the logic of image_render_color.  It is creating
        a pair of device colors.  Unfortunately, the process of creating the second
        one can change a half tone cache used by the first.  This affects the final
        image when the first color is then used to image pixels.

        * gxicolor.c [1.3] (+27 -15):
        image_render_color creates a pair of device colors and then compares them.
        Unfortunately the process of creating the second device color can alter
        the halftone cache used by the first.  This can occur when the halftone
        cache is small (4096 bytes) and there is not enough room for a cache
        entry for each level.  The fix is to reload the cache by remapping the
        first color before it is used to render a pixel.
        
        Note:  This problem also affects non DeviceN code but is less visible
        since a large cache (100000 bytes) is used for many situations.

        Modified Files:
        
          lib/gs_ll3.ps
            Added code to create the setoverprintmode and currentoverprintmode
            operators.
        
          src/gconf.c
            Add the gx_compositor_list array, to list the set of compositor
            types compiled into the system. Also provided the gs_find_compositor
            procedure, to locate a compositor method vector based on its
            type identifier.
        
          src/gdevdgbr.c
            Fixed several bugs in gx_get_bits_copy, for cases in which the
            transfer of output data involves a skew (bit shift) but no color
            conversion (a case that is apparently used only by the overprint
            facility). This case uses the copy_mono method for the 1-bit
            memory device. The invocation of this method had two problems:
        
              1. The temporary device created for the transfer had uninitialized
                 width and height fields. Because copy_mono will invoke the
                 fit_copy macro, these fields must be set to reasonable values.
        
              2. The width passed to copy_mono must be bit-width, as the
                 method for a depth == 1 device is used. Previously, the
                 pixel width was used.
        
          src/gdevx.c
            Fixed a problem in x_copy_image. If the image passed to this routine
            contains more than one pixel, the colors_and and colors_or fields were
            not updated. Because these fields are only used for optimization, and
            properly updating them in this situation is potentially expensive,
            they are now just set to safe values (colors_and = 0;
            colors_or = (x_pixel)(-1)).
        
          src/genconf.c
            Added to "-comp" option to support construction of a list of
            compositors compiled into the system.
        
          src/gs.mak
            Added the SETCOMP and ADDCOMP macros, to provide access to the
            -comp option of genconf.c.
        
          src/gsalphac.c
            Exported the gs_composite_alpha_type structure, and added a compositor
            type identifier to this structure. Also modified the de-serialization
            (read) method for this size so that the data string provided be large
            enough but not necessarily exactly the right size, and to return the
            number of bytes actually read (or an error code).
        
          src/gscdefs.h
            Added a prototye for gs_find_compositor (see gconf.c above).
        
          src/gscolor.c
            Modified gx_set_device_color_1 to turn off overprint (and overprint
            mode).
        
          src/gsovc.c:
            1. Modified the de-serialization method (read) to return the number of
               bytes actually read (or an error code).
            2. Renamed gs_overprint_type to be gs_composite_overprint_type, so as
               to conform to the new convention for compositor names.
            3. For the overprint devices, set the get_xfont_procs, get_xfont_device,
               and text_begin methods to use the corresponding default methods,
               rather than the forwarding methods. Device-supported fonts are
               incompatible with overprint, as the required low-level calls may
               not be made. While the text_begin method is not itself a rendering
               method, it does record an imaging device, and this device must
               be the overprint device rather than the target device. If the
               forwarding text_begin method is used, the recorded imaging device
               would be the target device.
            4. Modified update_overprint_params to avoid use of the overprint
               devices for cases in which overprint is true, but all color
               components are to be drawn. Though the output is not changed, use
               of the non-overprint device improves performance in this case.
            5. Modified the default overprint compositor creation method
               (c_overprint_create_default_compositor) to ignore overprint
               requests if the current color model has only a single component.
               Overprinting can never have an effect in this situation, and
               avoiding these cases also avoids difficulties with mask caching
               devices (such as are used with the character cache).
        
          src/gsstate.c
            Modified gs_state_update_overprint to update the color model mapping
            procedures and unset the device color. Though updating the overprint
            status will never change the color model, the overprint devices
            require a special set of forwarding color model mapping procedures.
        
          src/gxclimag.c
            Implemented the clist_create_compositor procedure (the create_compositor
            method for the command list device).
        
          src/gxclpath.c
            Replaced the cmd_opv_put_params code (0xdf) with cmd_opv_extend. This
            code indicates that the subsequent byte should be read and interpreted
            as a command from the gx_cmd_ext_op enumeration. Currently, this
            enumeration has two elements, cmd_opv_ext_put_params (the put_params
            method) and cmd_opv_ext_create_compositor (the create_compositor
            method).
        
          src/gxclrast.c
            1. Made the code parsing changes required by the new cmp_opv_extend
               code (see gxclpath.h above).
            2. Added the read_create_compositor procedure, to interpret the
               cmd_opv_ext_create_compositor command.
        
          src/gxclutil.c
            Modified cmd_put_params for the new cmp_opv_extend/cmd_opv_ext_put_params
            coding techinque.
        
          src/gxcmap.c
            Modified gx_set_cmap_procs to handle devices that have no
            get_color_mapping_procs method (such as mask caching devices).
        
          src/gxcomp.h
            Added the comp_id field to the gs_composite_type_t structure. Also
            added macros for the alpha and overprint compositors (the only two
            compositors in the current system).
        
          src/gxoprect.c
            Fixed typo in pack_scanline_lt8: the source data pointer was not
            being advanced.
        
          src/gxoprect.h
            Fixed typo in RCS identifier comment.
        
          src/lib.mak
            1. Updated several dependency lists.
            2. Added code to generate the list of compiled compositors.

        Removes the half tone cache from the imager state structure.  Changes the
        way that half tones are copied.  Changes where half tone caches are
        allocated.  Previously there were problems with half tone elements being

        One more revision of the "joint gray and color math".
        The last version had a problem in that the gray calculation might miss
        the fact that the calculation had produced a solid color (due to rounding
        in the calculation).  Then it would access an array out of bounds.

        code set from ORIMP to enable overprint and overprint mode.
        
        New Files:
        
          src/gxoprect.c
          src/gxoprect.h
            These files provide the low-level code for the fill_rectangle method
            of the overprint compositor device. There are three such procedures,
            which are used in different circumstances:
        
              gx_overprint_generic_fill_rectangle is always applicable, but is
                very slow as it must decode and re-encode the color for each pixel.
        
              gx_overprint_sep_fill_rectangle_1 is applicable to separable and
                linear color encodings whose depth is a divisor of
                8 * sizeof(mono_fill_chunk) = 32. This is always the
                case if depth <= 8. The code used in this case is, once past a
                large amount of setup, about as fast as can be achieved while
                using get_bits_rectangle.
        
              gx_overprint_sep_fill_rectangle_2 is applicable to all other
                separable and linear color encodings (all of which will have
                depth % 8 = 0). This uses a byte-wise method which is in principle
                slower than what could be achieved with a chunk-wise method, but
                is much easier to code in the general case (i.e.: for multiple
                possible depths). It will likely be faster in practice.
        
        Modified Files:
        
          lib/gs_init.ps
          lib/gs_setpd.ps
            Modified erasepage (and several other bits of code that erase the
            page) to turn off overprint before filling the page. This is necessary
            to preserve the meaning of erasepage.
        
          src/gsbitops.c
          src/gsbitops.h
            Added the bits_fill_rectangle_masked procedure, a generalization of
            the bits_fill_rectangle procedure that allows for a component mask.
            Also generalized bits_fill_rectangle (and bits_fill_rectangle_masked)
            to support depth > 8, so long as
            (8 * sizeof(mono_fill_chunk)) % depth = 0.
        
            Currently, bits_fill_rectangle_masked is used only by the overprint
            compositor device, but it can also be used by devices that can
            directly implement overprint (such as the memory device).
        
          src/gscdevn.c
            Modified check_DeviceN_component_names to initialize the
            component_map.sep_type field of the imager state to SEP_OTHER.
            Previously this field was not set for DeviceN color spaces, which
            confused some of the overprint code.
        
          src/gsovrc.c
            Implemented the real overprint_fill_rectangle procedures. As part of
            this work, added the local procedure swap_color_index, that swaps
            bytes in a color index as required to work with byte-oriented bitmaps
            on little-endian devices (only if depth > 8).
        
            Also fixed a parity bug in the creation of the retain_mask.
        
          src/gsovrc.h
            Fixed typo (/* $Id: History7.htm 12320 2011-03-30 08:51:40Z chrisl $Id: History7.htm,v 1.43 2005/10/07 18:35:12 ray Exp $ */).
        
          src/gxdcconv.c
            Modified color_rgb_to_cmyk to work if the imager state pointer
            operand is a null pointer. Note that in this case full undercolor
            removal and black generation will be performed, which is consistent
            with other such conversions in the code that do not have access to
            the imager state, but differs from the mapping used if the imager
            state is available but has no blackgeneration or undercolor removal
            map.
        
          src/lib.mak
            Added the gxoprect.$(OBJ) target and included this as a dependency
            in LIB4s. Also updated some other dependency lists.
        
        
        Additional file modified (not for overprint but needed for release):
        
          src/gdevdflt.c
            Added code to select a reasonable default value for the decode_color
            method, as this method is used extensively by the generic overprint
            implementation routines. The modifications are just a first pass to
            allow us to test the overprint code; they are not intended as a
            final solution.

        gxcmap.c [1.15] (+7 -7):
        A revised version of the "match the reference version" math for half tone

        * gxdevcli.h [1.10] (+2 -2):
        Corrected gx_device_has_color() macro.  It was reporting gray scale devices
        as color devices.

        * gxdevndi.c [1.9] (+8 -11):
        Add a kludge to emulate the different calculations used for gray versus

        regression testing.
        
        * gdevpbm.c [1.7] (+9 -5):
        Correct the pgmraw device.  The encode color routine was using three

        checkin for three separate code set releases from ORIMP, release
        notes follow in reverse chronological order.
        
        Notes:
        
         Modified files:
        
          gsstate.c
            Added code to ignore an error return from the create_compositor call
            in gs_state_update_overprint if the call was made to turn off
            overprint. This avoids errors for device configurations that do not
            (yet) support the create_compositor call, when running files that do
            not require overprint support.
        
          gsovrc.h
            Fixed a typo in a commment.
        
          gxclrast.c
            Fixed a re-entrancy problem in read_set_color_space that was introduced
            by the previous modification to this file.
        
          gsimage.c
            Added a comment concerning re-entrancy, and slightly modified another
            comment.
        
          gscspace.c
            Added some comments concerning re-entrancy.
        
        Notes:
        
        Modified Files:
        
          src/gsovrc.c
            Added full compositor device "plumbing". The overprint compositor
            now does all of the required device creation and setup work. The
            only piece still missing are implementations of the low-level
            rendering routines that actually implement overprint.
        
          src/gsptype1.c
          src/gsptype2.c
          src/gxcht.c
          src/gxdcolor.c
          src/gxdcolor.h
          src/gxht.c
          src/gxpcolor.h
            Added the method get_nonzero_comps to the gx_device_color_type_t
            structure (the gx_device_color methods). This method is used by
            the overprint code to determine which color component intensities
            have non-zero value, which must be known to implement overprint
            mode.
        
          src/gsovrc.h
          src/gscspace.c
            Changed the drawn_comps field of the gs_overprint_params_t
            structure from a byte array to a gx_color_index. This is a bit
            ugly, as the value is a bit map rather than an encoded color,
            but allows much simpler processing. (As in device colors, a
            gx_color_index is used because it is known to be large enough.
        
          src/lib.mak
            Updated dependency list for gsovrc.$(OBJ).
        
        Notes:
        
        New Files:
        
          src/gsovrc.c
            Implementation of the overprint compositor. For the moment, this is
            just a stub. This file will grow considerably in the next two releases.
        
        
          src/gsovrc.h
            Interface to the overprint compositor. This is in essentially final
            form, even though only a stub implementation of the compositor is
            available. This file also includes a lengthy comment describing when
            the compositor must be updated.
        
        
        Modified Files:
        
          lib/gs_ciecs2.ps
          lib/gs_ciecs3.ps
          lib/gs_cspace.ps
          lib/gs_devcs.ps
          lib/gs_devn.ps
          lib/gs_devpxl.ps
          lib/gs_icc.ps
          lib/gs_indxd.ps
          lib/gs_patrn.ps
          lib/gs_sepr.ps
            Incorporated an optimization of setcolorspace from the casper head.
            The optimization avoids setting the color space if it is the same as
            the current color space. gs_icc.ps also contains a fix for a bug
            in the handling of DataSources that are streams (rather than strings;
            Dan discovered and analyzed this bug).
        
            Note that this is a fairly complex optimization, and there were many
            problems with the head code that needed to be resolved. Among these
            were:
        
              1. An invocation of setcolorspace should always set the default
                 color for the operand color space, even if that color space is
                 identical to the current color space.
        
              2. If UseCIEColor is true, setcolorspace must be executed if
                 the operand color space involves device-specific color spaces.
                 This is because the Default{Gray,RGB,CMYK} instances of the
                 ColorSpace resource category may have changed.
        
              3. When UseCIEColor is changed from true to false in setpagedevcie,
                 the implicit initgraphics invocation must perform a setcolorspace
                 operation, even if the current color space is DeviceGray. This
                 is necessary to ensure that the un-substituted DeviceGray color
                 space is set as the current color space.
        
        
          lib/gs_init.ps
            In /showpage, replace the sequence "erasepage ... initgraphics" with
            "initgraphics 1 setcolor .fillpage 0 setcolor". This has the desired
            effect, and avoids two unnecessay invocations of setcolorspace.
        
        
          lib/gs_setpd.ps
            1. Modified the currentpagedevice pseudo-operator for cases in which
               the stored page device must be copied. Previously, the new copy
               was allocated in the current VM mode, which could cause
               invalidaccess errors if currentpagedevice was invoked while in
               global VM mode and composite objects stored in the page device
               dictionary were in local VM (this problem is present in the PS3
               FTS). The new code will allocate the copy in the save VM as the
               original dictionary.
        
            2. In setpagedevice, added code to set current color space to
               something other than DeviceGray if modification of the page device
               will set UseCIEColor to false. This is necessary for the
               setcolorspace optimization to function properly (see above).
        
            3. In the .postinstall pseudo-operator, replaced "erasepage initgraphics"
               with "initgraphics 1 setcolor .fillpage 0 setcolor". This avoids
               two unnecessary invocations of setcolorspace.
        
        
          src/gdevp14.c
            Added the pdf14_create_compositor method. This method will check if
            the compositor to be created is the overprint compositor. If so,
            the request to create the compositor will simply be ignored, as
            the gs_pdf14_device and its associated marking device must implement
            overprint directly.
        
        
          src/gscdevn.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for DeviceN color spaces.
        
        
          src/gscolor2.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for Indexed color spaces.
        
        
          src/gscpixel.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for DevicePixel color spaces.
        
        
          src/gscscie.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for CIEBased color spaces.
        
        
          src/gscsepr.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for Separation color spaces.
        
            3. Moved the gs_{set|current}overprint[mode] procedures to gsstate.c.
        
        
          src/gscsepr.h
            Moved prototypes for the gs_{set|current}overprint[mode] procedures
            to gsstate.h.
        
        
          src/gscspace.c
            1. Removed the color space equality check methods for the device-
               specific color spaces.
        
            2. Added the basic set_overprint procedures, to provide color-space
               specific setting of the overprint compositor.
        
            3. Modified the gs_cspace_{build|init}_Device{Gray|RGB|CMYK}
               procedures to use the same identifier for all instances of
               the parameterless color spaces (i.e.: all DeviceGray instances
               will have the same id, as will all DeviceRGB instances, but the
               id for any DeviceGray will differ from the id for a DeviceRGB
               instance). This enables an optimization in the gs_setcolorspace
               routine that had been lost in the previous code modification.
        
        
          src/gscspace.h
            Removed prototype for the gs_color_space_equal procedure.
        
        
          src/gsicc.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for ICCBased color spaces.
        
        
          src/gslib.c
            Modified test9 to explicitly reset the current color space; this
            is no longer done by gs_initgraphics.
        
        
          src/gspcolor.c
            Added set_overprint method for pattern color spaces, removed the
            equality check method.
        
        
          src/gsstate.c
            1. Added code to update the overprint compositor when the current
               color space, current device, overprint, or overprint mode
               settings change. Included in this change is code in gs_grestore_only
               that updates the overprint compositor as part of the grestore
               operation when this is required.
        
            2. Moved the gs_{set|current}overprint[mode] procedures to this file
               from gscsepr.c. This is more convenient for the new code, and
               gscsepr.c was never a particularly appropriate place for these
               routines.
        
            3. Modified gs_initgraphics to not reset the current color space or
               current color. For PostScript this must now be done in the
               PostScript code to properly handle color space substitution.
               Other clients that use this procedure (the XL interpreter is the
               only one (aside from gslib.c)) can easily reset these parameters
               as well.
        
        
          src/gsstate.h
            Moved prototypes for the gs_{set|current}overprint[mode] procedures
            here from gscsepr.h.
        
        
          src/gxccache.c
            Modified gx_image_cached_char to just return if the current color
            is a pure gx_no_color_index (transparent).
        
        
          src/gxcspace.h
            1. Removed the equality check method.
        
            2. Added the set_overprint method.
        
        
          src/gxipixel.c
            Modified the gx_image_enum_begin to allow the Decode array for
            imagemasks to have any two distinct numbers, rather than just 0 and
            1. This matches the behavior of all Adobe systems (though not the
            documentation), and avoids some spurious failures when running the
            FTS.
        
        
          src/gxpcmap.c
            Modified pattern_accum_copy_mono to just return if both the foreground
            and background colors are gx_no_color_index (transparent). If this is
            not done, the mask device's copy_mono procedure may generate an
            error when invoked (this is true for mem_mono_copy_mono).
        
        
          src/iutil.c
            Modified obj_eq to consider two 0-length arrays to be equal,
            irrespective of their type and their pointers (the latter aren't
            meaningful if the array length is 0). This matches the PostScript
            documentation and the behavior of Adobe systems. It also fixes
            some spurious failures in the FTS.
        
        
          src/lib.mak
            Added an entry for gsovrc (the overprint compositor), and updated
            various dependency lists.
        
        
          src/zfdcte.c
            Modified the DCTEncode procedure (zDCTE) to allocate the
            jpeg_compress_data and subsidiary memory structures in current VM.
            Previously these structures were allocated in gs_default_memory,
            which does not support garbage collection. Since the structures
            were subject to garbage collection and relocation, chaos could
            and, in the case of FTS file 119-28.ps, did ensue.
        
            Note that these structure must be allocated immovable, which
            requires a considerable amount of overhead when using VM. A better
            approach would be to allocate them in gs_default_memory, and use
            a more sophisticated structure descriptor for the stream_DCT_state
            structure (st_DCT_state).
        
        
          src/zgstate.c
            Slightly simplified zinitgraphics, and updated a comment in this
            procedure.
        
        
          src/zmisc.c
            Modified realtime operator to set a zero point at boot time. This
            avoids an annoying delay in running FTS panel 211-01 (206-01.ps).
        
        
          zpcolor.c
            Modified the pattern_paint_prepare procedure to use gs_setdevice_no_int
            rather than gx_set_device_only. It is not clear why the latter
            procedure was ever used in this location, and it is now important to
            use the former procedure so the overprint compositor may be properly
            updated.

        Overprint implementation (Jan Stoeckenius)
        
        This is a preliminary code release for the overprint capability. The
        release does not contain the overprint facility itself; it consists
        entirely of modifications so that color space changes will occur in a
        predictable fashion.
        
        Files removed:
        
          src/gshsb.c
          src/gshsb.h
          src/gscssub.c
          src/gscssub.h
          src/zhsb.c
        
        
        Files added:
        
          lib/gs_cspace.ps      PostScript portion of the basic color space handling;
                                see the extensive comment at the head of the file
                                for information. Note that color space substitution
                                and the hue-saturation-brightness (HSB) color space
                                are now fully implemented in the PostScript code;
                                the interpreter and the graphic library are no longer
                                involved in or even aware of these features.
        
          lib/gs_devcs.ps       Implementation of the DeviceGray, DeviceRGB, and
                                DeviceCMYK color spaces.
        
          lib/gs_ciecs2.ps      Implementation of the LangaugeLevel 2 CIEBased color
                                spaces: CIEBasedA and CIEBasedABC.
        
          lib/gs_ciecs3.ps      Implementation of the LanguageLevel 3 CIEBased color
                                spaces: CIEBasedDEF and CIEBasedDEFG
        
          lib/gs_devpxl.ps      Implementation of the DevicePixel color spaces
        
          lib/gs_indxd.ps       Implementation of the Indexed color space.
        
          lib/gs_sepr.ps        Implementaton of the Separation color space.
        
          lib/gs_devn.ps        Implementation of the DeviceN color space.
        
          lib/gs_patrn.ps       Implementation of the Pattern color space.
        
        
          lib/gs_img.ps         Implementation of the traditional (non-dictionary)
                                form of the image and imagemask operators, and the
                                colorimage operator (including the Next alphaimage
                                facility). The interpreter now provides only the
                                dictionary form of the image and imagemask operators,
                                including a variation that provides alpha-channel
                                support.
        
                                Also modified the handling of color spaces for
                                ImageType 2 images. This slightly changes the behavior
                                of these images. If PixelCopy is defined to be true
                                in the image dictionary but such a copy cannot be
                                supported, an error will be generated. This is in
                                agreement with Adobe's documentation, but differs
                                from the earlier behavior.
        
          The code for Indexed, Separation, and DeviceN color spaces
          incorporates code, courtesy of Dan, that will invoke the lookup or
          tint transform procedure in the appropriate context if this is
          appropriate (if there is a lookup procedure for Indexed color spaces
          or the alternate color space is in use for Separation and DeviceN
          color spaces). Currently this is not done recursively (if an Indexed
          color space has a DeviceN base color space, for example), but that
          has not proven necessary in practice. If necessary, it can be added.
        
        
          src/zcolor3.c         Code to implement the .setuseciecolor operator. This
                                operator is used only in the setpagedevice code, and
                                makes certain that the use_cie_color field in the
                                interpreter's graphic state mirrors the setting of
                                the UseCIEColor page device parameter.
        
        
        Files modified:
        
          lib/gs_dpnxt.ps       Added PostScript implementation of the alphaimage
                                operator. This uses the internal .alphaimage
                                operator, which is a variation of the image
                                operator that provide alpha-channel support.
        
          lib/gs_icc.ps         Rewritten to implement the ICCBased color space
                                in the new scheme. See the comments in
                                lib/gs_cspace.ps for information.
        
          lib/gs_init.ps        Modified to include gs_cspace.ps, gs_devcs.ps,
                                and gs_img.ps, and to remove img_util_dict and
                                .cspace_util_dict from userdict at the end of
                                initialization.
        
          lib/gs_lev2.ps        All explicit color spaces removed (with one
                                exception, and replaced by inclusion of gs_devpxl.ps,
                                gs_ciecs2.ps, gs_indxd.ps, gs_sepr.ps, and
                                gs_patrn.ps. The only remaining color space support
                                feature is moving the setcolorspace and setcolor
                                pseudo-operators, and the colorspacedict dictionary,
                                to level2dict. This must be done here, as it is not
                                known that level2dict exists when gs_cspace.ps is
                                first run.
        
                                Also removed all explicit image support. This is
                                now handled by gs_img.ps (see above).
        
          lib/gs_ll3.ps         Removed the old support for color space substitution;
                                this is now handled directly by the color space
                                code (see the comments in gs_cspace.ps for
                                information). Added inclusion of gs_ciecs3.ps and
                                gs_devn.ps.
        
          lib/gs_setpd.ps       Added support for the .getuseciecolor and
                                .setuseciecolor operators. This maintains a
                                "mirror" of the UseCIEColor parameter in the
                                graphic state, to allow fast access.
        
          src/gdevnfwd.c        In gx_forward_get_color_mapping_procs, added a check
                                for the case of a target device which has no
                                get_color_mapping_procs procedure. This led to a
                                segmentation violation crash for FTS file 296-01.ps
                                The fix may not be the correct one, as we are not
                                certain why a device would lack this method.
        
          src/gdevp14.c         Replaced a use of the shared field in the graphic state
                                with a color space allocated on the C-language stack.
        
          src/gdevpsdi.c        Replaced an instance of use of the gs_cspace_DeviceRGB
                                procedure.
        
          src/gscolor.c         Removed gs_currentgray and gs_currentrgbcolor. Modified
                                gs_setgray and gs_setrgbcolor to use gs_setcolorspace
                                and gs_setcolor. This eliminates use of the
                                gs_current_Device*_space routines.
        
          src/gscolor.h         Removed prototypes for gs_currentgray and
                                gs_currentrgbcolor.
        
          src/gscolor1.c        Removed gs_currentcmykcolor. Modified gs_setcmykcolor
                                to use gs_setgray and gs_setcolorspace.
        
          src/gscolor1.h        Removed prototype for gs_currentcmykcolor.
        
          src/gscolor2.c        Removed gs_currentcolorspace_index. Removed the color
                                index tracking used as part of the color space
                                substitution method.
        
          src/gscolor2.h        Removed prototype for gs_currentcolorspace_index.
        
          src/gscscie.c         Eliminated use of the gs_cspace_Device* routines.
        
          src/gscsepr.c         Fixed a pair of typos in revision 1.6 of the code.
                                In gs_cspace_set_sepr_proc and
                                gx_concretize_Separation, the code was still accessing
                                pcspace->params.device_n when it wanted to access
                                pcspace->params.separation. This caused a crash in
                                FTS file 245-01.ps.
        
          src/gscspace.c        Removed gs_cspace_Device* procedures.
        
          src/gscspace.h        Removed prototypes for gs_cspace_Device* procedures.
        
          src/gsimage.c         Removed use of the gs_cspace_DeviceGray procedure.
        
          src/gsiparam.h        Removed the gs_image_t_int_{gray, rgb, cmyk} macros.
        
          src/gsistate.c        Updated code to reflect removal of the shared field in
                                the imager state. As part of this, the
                                rc_free_imager_shared and gx_device_color_spaces_free
                                procedures were removed.
        
          src/gslib.c           Removed use of the gs_current_Device*_space and
                                gs_image_t_init_gray procedures.
        
          src/gspcolor.c        Removed reference to the orig_cspace_index field,
                                which is no longer part of the library's graphic
                                state.
        
          src/gsptype1.c        Eliminated use of the gs_cspace_DeviceGray procedure,
                                and insured that a color space is set as the current
                                color space before it is used.
        
          src/gsstate.c         Removed code that maintained the device_color_spaces
                                field (color space substitution), which is no longer
                                in the library's graphic state.
        
          src/gxclrast.c        Removed use of the gs_cspace_Device* procedures.
        
          src/gximage3x.c       Removed use of the gs_image_t_init_gray procedure.
        
          src/gximage2.c        Modified color space handling for ImageType 2 images.
                                Note that there was and still is a problem with the
                                handling of transformations in this code.
        
          src/gxistate.h        Removed the shared field of the imager state, all
                                associated structures and prototypes, and modified
                                the affected GC macros. The gx_device_color_spaces_t
                                structure was previously used in the graphic library's
                                state as well, but that use has been eliminated.
        
          src/gzstate.h         Removed the the device_color_spaces field, and modified
                                the requisite GC macros
        
          src/idparam.c         Modified dict_float_array_check_param to handle
                                packed (short or mixed) arrays.
        
          src/igstate.h         Added the use_cie_color field. This is a mirror for
                                the UseCIEColor parameter of the page device, used
                                because the currentpagedevice operator is potentially
                                expensive.
        
          src/iimage.h          Modified to restrict the interpreter to just the
                                dictionary form of the image and imagemask operator.
                                This removes the zimage_opaque_setup, zimage_data_setup,
                                and zimage_multiple prototypes, and moves the
                                image_params structure and the image1_setup
                                prototypes to this file (from iimage2.h).
        
          src/iimage2.h         Moved everything except the prototype for
                                process_non_source_image to iimage.h.
        
          src/iutil.c           Added process_float_array procedure, to allow packed
                                (short, mixed) arrays of numbers to be handled.
        
          src/iutil.h           Added prototype for the process_float_array procedure.
        
          src/zcolor.c          Removed:
                                  zcurrentgray, zcurrentrgbcolor,
                                  setgray, setrgbcolor
                                Moved (from zcolor2.c):
                                  zcurrentcolor, zcurrentcolorspace,
                                  zsetcolor, zsetcolorspace
                                Added:
                                  zgetuseciecolor   queries the use_cie_color field
                                                    in the interpreter state
                                  zsetdevcspace     sets a DeviceGray, DeviceRGB, or
                                                    DeviceCMYK color space
        
          src/zcolor1.c         Removed zcurrentcmykcolor, zsetcmykcolor, and
                                zcolorimage.
        
          src/zcolor2.c         Removed everything in prior version. Added
                                zusealternate, to test if an alternate color space
                                is being used (for a Separation, DeviceN, or ICCBased
                                color space), or if a base color space is in use
                                (for an Indexed or a Pattern color space that uses
                                a base space).
        
          src/zdpnext.c         Replace the alphaimage operator with .alphaimage,
                                which has the semantics of the dictionary form of
                                the image operator.
        
          src/zgstate.c         Modified the initgraphics operator to set the
                                colorspace.array field to a legitimate color space
                                (previously it was set to a null object). Also
                                inserted code to initialize the use_cie_color field
                                to false.
        
          src/zimage.c          Removed the traditional-form image and imagemask
                                operators (zimage and zimagemask), and moved the
                                dictionary form of these operators to this file
                                from zimage2.c. Also, added the has_alpha parameter
                                to the data_image_params and pixel_image_params
                                procedures, to support the .alphaimage operator.
        
          src/zimage2.c         Moved everything except the process_non_source_image
                                procedure to zimage.c.
        
          src/zimage3.c         Updated calls to data_image_params and
                                pixel_image_params to add has_alpha parameter.
        
          src/zmisc3.c          Removed .setsubstitutecolorspace operator.
        
          src/zpcolor.c         Modified .setpatternspace to handle a packed (short,
                                mixed) array operand.
        
          src/zshade.c          Modified build_mesh_shading to handle a packed (short,
                                mixed) DataSource array operand.
        
          src/ztrans.c          Modified calls to data_image_params and
                                pixel_image_params to add has_alpha operand.
        
          src/watclib.mak       Removed reference to the hsblib.dev, which no longer
                                exists and which, for some unknown reason, was directly
                                included in this makefile. Does anyone still use this
                                file?
        
          src/int.mak           Removed hsb.dev and the zimage2_l2 operators, added
                                zcolor3.c, updated various dependency lists.
        
          src/lib.mak           Removed hsblib.dev and gscssub.[ch], updated various
                                dependency lists. Note that this file has not yet
                                been modified to always compile with Level 3 support.

        * vdtrace.c [1.2] (+1 -2), lib.mak [1.12] (+2 -2), gslib.c [1.3] (+15 -7):
        Changes required to get the GS lib to build.
        
        * zcssepr.c [1.4] (+22 -40), zcsdevn.c [1.7] (+6 -6), zcolor2.c [1.6] (+1 -28),

        1. Revised version of the Separation color space implementation.  The /None
        case now works.  The "normal" case is now implemented as part of the separation
        color space instead of using the DeviceN logic.
        2. The Separation and DeviceN color space handler for getting the alternate
        color space now return NULL if the alternate color space is not being used.
        (As pere request from ORIMP.)
        3. The DeviceN color space had a problem with an ICC alternate space. Corrected.

        * gsbitops.h [1.3] (+17 -6):
        Added casts to reduce warning casting warnings.
        

Thu Apr 25 04:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gdevxcf.c [1.7] (+65 -22):
        Apply RGB->device and CMYK->device profiles only in DeviceN color model;
        in DeviceRGB and DeviceCMYK color models, the mapping is defined by
        the PostScript spec. Also map DeviceGray colorspace to CMYK.
        

Tue Apr 23 08:00:00 2002 GMT        Raph Levine    raph@meerkat

        * gdevxcf.c [1.6] (+117 -8), gdevdflt.c [1.9] (+9 -6):
        Makes xcfcmyk device agile in ProcessColorModel. Changes "expert
        system" logic slightly so that is_like_DeviceRGB is only called
        when filling in the default is needed.

        * lib.mak [1.11] (+3 -2), int.mak [1.4] (+3 -2):
        These two files should have been included in the previous commit.
        
        * zfsample.c [1.2] (+22 -21), zcssepr.c [1.3] (+79 -94),

        gscsepr.c [1.5] (+84 -176), gscdevn.h [1.5] (+9 -6), gscdevn.c [1.7] (+25 -19):
        Changed the separation color space to use common logic with the DeviceN
        color space.  This commit also brings the DeviceN code up to date.  This
        includes the function sampling logic in zfsample.c.  This code handles the
        /All case and the normal separation case.  The /None case is not handled
        correctly.  All components are erased (zeroed) when /None is selected.
        
        * gscspace.h [1.6] (+3 -1):
        I was over zealous in cleaning up this file.  Restored defintion of
        gx_indexed_map.
        

Tue Apr 23 04:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        devs.mak [1.10] (+2 -2):
        These changes are required to initialize the "display" device to work
        with the DeviceN code.  This involves setting up the correct color_info
        structure for the device and the DeviceN related procs.
        

Tue Apr 16 07:00:00 2002 GMT        Henry Stiles    henrys@meerkat

        * gxdevcli.h [1.9] (+3 -12):
        removes duplicate dci_std_color() macro definition.
        

Tue Apr 16 05:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gdevdevn.c [1.8] (+2 -3):
        Some more corrections to the initialization of the spotrgb and spotcmyk
        device structures.  Apologies to Henry.  I misunderstood the results from
        the cvs merge.  Henry did not mangle the bpp, etc. in the previous commit.
        

Tue Apr 16 04:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxdither.h [1.4] (+10 -10):
        Added prototype for function gx_render_device_DeviceN.
        Removed some unused macro definitions.
        
        * lib.mak [1.10] (+2 -2), gxcmap.c [1.9] (+49 -31):
        1.  Added included of string_.h.  This resolves some undefined function
        prototypes.
        2.  Corrected handling of transfer functions and halftoning.  (Transfer
        functions were not being applied if halftoning was being done.)
        3.  Finished the half tone code for DeviceN color model devices.
        4.  Some misc code clean up to remove misc warning messages.
        

Tue Apr 16 03:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gsht1.c [1.5] (+2 -2):
        We were not allocating a half tone cache for the "gray" component.
        
        * gdevdevn.c [1.7] (+22 -15):
        1.  Convert the spotcmyk device back to a half toned (1 bit per pixel per
        component) device.  This had been changed by Henry is the last commit.
        2.  Corrected the gray color space to cmyk color model handler.  This was
        corrupting the cmykspot colors.
        3.  Corrected a couple of problems in the spotcmyk device.  (Garbage data
        in the last half of byte if a line had an odd number of pixels.  Bad bps
        and planes in the pcx header - the cmyk pcx output file is really a 4 bit
        device with a color mapping table.)
        

Tue Apr 16 00:00:00 2002 GMT        Henry Stiles    henrys@meerkat

        * gstype42.c [1.4] (+4 -2):
        conditional compile (hack) to prevent freeing glyph data when library is
        built with pcl.  This is a long standing issue supported by a thousand
        lines of email and 0 lines of code.

        - modification for pcl build.
        - color info "expert system".
        

Thu Apr 11 22:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * msvccmd.mak [1.3] (+4 -2):

        * gdevxcf.c [1.4] (+153 -43):
        Adds ICC profile paths to RGB->Color Model and CMYK->Color Model
        transforms in xcfcmyk device. Use ProfileRgb (3->N) and ProfileCmyk
        (4->N) device parameters to install ICC transforms.

        Changes to enable the use of the clist device (banding) with the DeviceN
        colorspaces and devices.  This is still missing the clist commands for
        transfer functions and the DeviceN component map.
        

Wed Mar 27 01:00:00 2002 GMT        Raph Levine    raph@meerkat

        * gdevxcf.c [1.3] (+131 -6), devs.mak [1.9] (+6 -3):
        Adds some ICC color profile ability to the xcf device, for testing
        purposes.
        

Tue Mar 26 21:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxdevndi.c [1.6] (+40 -5), gdevplnx.c [1.3] (+3 -3):
        Add definition of fc_color_quo and some other changes that were required
        as part of eliminating the gxdither.c module.
        

Tue Mar 26 05:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gshtx.h [1.4] (+1 -3):
        Removed sepr_name parameter from function prototypes.  This change
        goes with an earlier change to gshtx.c.
        

Tue Mar 19 19:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gshtx.c [1.6] (+1 -13):
        Changes requested by henry.  The separation name has been removed
        from the calling sequence for gs_ht_set_threshold_comp and
        gs_ht_set_mask_comp.  (These routines are used by PCL.)
        

Mon Mar 18 07:00:00 2002 GMT        Henry Stiles    henrys@meerkat

        * gdevpdfc.h [1.1] (+62 -0):

        gdevcmap.c [1.6] (+16 -16):
        operand changes and misc. fixes for compiling pcl.  I used pcl because
        it was not clear how even to compile the gslib target.  With
        implementations for gs_ht_set_mask_comp() and
        gs_ht_set_threshold_comp() it will be possible to build pcl and verify
        the changes to these files from pcl.
        

Mon Mar 18 05:00:00 2002 GMT        Henry Stiles    henrys@meerkat

        * gdevpdfg.c [1.5] (+4 -3):
        pdf_update_transfer() was not returning a value resulting in the
        previously encountered pdf problems.  It now retuns 0 and prints a
        diagnostic message saying it is not implemented.  Setting the
        /DeviceGray color model does not work properly in pdfwrite.

        fixed.  Running the interpreter with pdfwrite fails upon the first
        graphics painting operation returning an uninitialized error code, so
        this will need more work.

Sat Mar  2 05:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxcht.c [1.10] (+9 -5):
        This is an optimization which reduces the number of encode_color calls
        required when halftoning 5 or more components.
        

Thu Feb 28 00:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxcindex.h [1.4] (+12 -10):
        The value of gx_no_color_index was being forced to be a 'long' value
        instead of matching the size of gx_color_index.  Change it to use gx_color_index
        as its type.  (May create a problem on Irix 5.2.)
        

Wed Feb 27 08:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxcht.c [1.9] (+46 -48):
        Now the halftoning will work with almost any number of components.
        

Wed Feb 27 02:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxcht.c [1.8] (+6 -5):
        THis fix corrects the halftone hander which is used to handle more than four
        components.  It ws not correctly handling the mixture of a fully saturated
        component and some halftoned components.  (Worked with zero value components.)
        

Thu Feb 21 07:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxcht.c [1.7] (+13 -6):
        This corrects a problem with some magenta coloring around the muzzle of
        the tiger.eps file when using the pcxcmyk device.
        
        Note:  There is still some stuff to check.  This fix primarily uses
        special code for 1 bit cmyk colors (same as previous versions of GS).
        The non 1 bit routines should produce the same result do not.
        

Thu Feb 21 04:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxcht.c [1.6] (+16 -38):
        Corrected problems in set_ht_colors_le_4 which was preventing it from
        compiling.  This is the halftoner for non single bit 4 or less components.
        

Tue Feb 19 05:00:00 2002 GMT        Henry Stiles    henrys@meerkat

        * unix-gcc.mak [1.5] (+3 -8), gdevm48.c [1.4] (+2 -2):
        The pixel size was incorrectly set to 3 instead of six (jan).  Adds
        CPPFLAG define for the long long so it works properly with raph's xcf
        device.
        

Tue Feb 19 05:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxcht.c [1.5] (+13 -14):
        Corrects a problem with an unknown error being returned in 'fill' when
        drawing tiger.ps using the pcxcmyk device.  Some of the color halfoning
        code is disabled because it is not compatible with the devicen device
        color mapping routines.  This fix corrects some of these problems.
        
        
        Note:  There are still more problems in this module related to the DeviceN
        implementation.  There are many places that that assume 3 or 4 colors
        only.
        
        * gdevm40.c [1.4] (+2 -2):
        Matching change to the change in gdevm48.c.  Changed a hard coded value
        of 3 for the pixel size to PIXEL_SIZE.  The 3 was a holdover from code
        copied from gdevm24.c.  Note: gdevm56.c and gdevm64.c are already
        correct.
        

Fri Feb 15 06:00:00 2002 GMT        August Daniel Coby    dan@meerkat

        * gxdevcli.h [1.6] (+1 -13):
        Removed unnecessary and incorrect dci_deviceN macros that had been
        previously inserted.  As per request for Jan. S.
        

Tue Feb 12 18:00:00 2002 GMT        Raph Levine    raph@meerkat

        * gdevxcf.c [1.1] (+1047 -0), devs.mak [1.6] (+12 -1):
        Adds an "xcf" device, which generates Gimp XCF file format, with
        additional channels for DeviceN separations.

        gdevdsp.c [1.6] (+2 -1):
        This commit enables halftoning.  Note:  The module gsdevndi.c contains
        the interface for setting up a halftone.
        
        Also corrects a problem with purple tigers caused by changes in gdevdsp.c
        in the last commit.

        This commit creates a halftone array in the imager state which contains
        one halftone (and transfer function) for each device colorant.

        more color operand fixes from the MSVC build as reported by Dan.  This
        snapshot compiles with msvc ver 6.0.
        

Thu Jan 24 01:00:00 2002 GMT        Henry Stiles    henrys@meerkat

        missed color encoding operand changes.  These devices were not
        dependencies in the unix gcc build.  Adds epson device (back) to gcc
        makefile.  It is unclear why the epson devices were removed.

                  - color encoding operand changes.
        
        gxdevice.h - removed obsolete encode and decoding procedure
                     prototypes.  Remaps default rgb_color and color_rgb to new default
                     encode and decode procedures.
        
        msvc32.mak and unix-gcc.mak
                   - removes pdfwrite device for color mapping doesn't work
                     with new color mapping, device not scheduled for first
                     devicen release.  unix-gcc.mak now has the long long hack, like msvc32.mak
                   - -O0 for debug *NOT* -O.
                   - removes -Wtraditional, can't find real warnings in the
                     sea of messages.
                   - adds devicen devices to unix-gcc.mak
        zpdnext.c  - color encoding mapping changes.
        zfcid0.c & zfcmap.c
                   - #ifdefs out profile and debugging code which should not be in
                     this module as it depends on the pdfwrite device.

        This is a first pass at implementing the transfer functions in the DeviceN
        code.  This version still has the 'color_indices' array.  This should be
        removed shortly.

        * gsmisc.c [1.2] (+2 -2):
        ilog2() had a misplaced parenthesis.  Results that were multiples of
        4, (like ilog2(16) and ilog2(256)) returned 0.  This should get fixed
        in the main gs tree as well.

        transfer elements of the graphics state.

        Removed gscsepnm.h.  This file is no longer used.  It was used to describe
        separation names for the standard colors (G, RGB, and CMYK).  The DeviceN
        effort now allows for any color name.

            tones) based upon the colorant names.  Note:  This still does not
            work but we want to get a first pass into CVS.

        * gs_init.ps [1.8] (+14 -3):
        Modified File: (jan)
        
          lib/gs_init.ps    Modified .sethireshalftone to ignore components
                            not present in a device when determining if gamma
                            correction is required due to (imputed) dot-gain.
                            This corrects a problem with certain three-color
                            devices whose nonexistant gray component was
                            inappropriately causing gamma correction to be
                            applied.

        Modified Files: (jan)
        
          lib/gs_cspace.ps
            Added _setcolorspace_nosub, a variation of the setcolorspace operation that
            avoids color space substitution. This is required for ICCBased color spaces,
            as they may be used to substitute for a device-specific color space, but
            use that same device-specific color space as an alternative space. If the
            alternative space was used (or even if it wasn't, in the prior code), an
            infinite loop would result (the eventual error is execstackoverflow).
        
          lib/gs_icc.ps
            Modified the cs_install routine for ICCBased color spaces to use the new
            _setcolorspace_nosub procedure.
        
          lib/pdf_draw.ps
            Removed the color substitution scheme used by resolvecolorspace. This has
            been superseded by the PostScript-based scheme.
        
          lib/pdf_main.ps
            Implemented color space substitution using PostScript's method. This works
            for all color spaces and, with the above noted modifications to
            gs_cspace.ps and gs_icc.ps, avoids infinite-loop problems. The
            earlier code did not implement color space substitution for
            DeviceCMYK (the code was just missing) and in rare cases could
            suffer from infinite loops.
        
          src/zcolor.c
            Correct a typo: the .setdevcspace operator was included twice in the
            zcolor_op_defs array.

        The following should be prominently posted in full view of all
        software engineers:
        
          ***Do not use caches to hold unreplaceable data***
        
        Failure to follow that rule of good programming is the heart of the
        problem with FTS panel 245-04 (file 245-01.ps).
        
        The immediate cause of the problem is the optimization put in the
        setcolorspace code to avoid repeatedly setting the same color space.
        The steps that lead to the error are the following:
        
          1. The job sets a CIEBasedABC color space as the current color
             space. The white and black point information from the color
             space dictionary is combined with the white and black point
             information in the color rendering dictionary to sample the
             TransformPQR procedures in that dictionary. The resulting
             data is placed in the joint CIE cache. All of this activity
             ends with an execution of the internal operator cie_tpqr_finish
             (zcrd.c). This operator has two side-effects:
        
                 The TransformPQR data structure in the cie_render structure
                 of the current state is set to TransformPQR_from_cache, which
                 indicates that the PQR phase of the CIE color mapping (the
                 white point point adjustment) is to be done via the joint CIE
                 cache.
        
                 The gs_cie_cs_complete procedure is invoked with the "init"
                 argument set to false, indicating that no further
                 initialization is required for the joint CIE caches. This
                 causes the status flag in those caches to be set to
                 CIE_JC_STATUS_INITED, indicating that the caches are ready
                 to use.
        
          2. The job calls gsave. Since the joint CIE caches can be shared by
             multiple graphic states, the cache reference count is incremented.
        
          3. The job sets a pattern color space, whose base color space is the
             current (CIEBasedABC) color space.
        
             The PostScript interpreter in Ghostscript uses the convention that
             a base or alternative color space will always be set as the current
             color space immediately before the enclosing color space is set.
             The cs_install procedure for the pattern color space
             (lib/gs_patrn.ps) invokes setcolorspace on the base space. Because
             this is already the current color space, nothing happens.
        
          4. Immediately afterwards, the cs_install procedure invokes the
             .setpatternspace operator on the enclosing pattern color space.
             Through a couple of layers, this will invoke the "install_cspace"
             method for pattern color spaces, the gx_install_Pattern
             (gspcolor.c). This will in turn invoke the "install_cspace" method
             for the base color space, in this case gx_install_CIE.
        
          5. Through a few additional layers, gx_install_CIE will also call
             gs_cie_cs_complete (see (1) above), but this time the "init"
             variable will be set to true, indicating that additional
             initialization is required.
        
             gs_cie_cs_complete will invoke gx_currentciecaches, whose purpose
             is to make sure that new copies of the joint CIE cache is created
             when necessary. Since the reference count on the existing cache is
             larger than 1 (see (2) above), a unique copy of the cache is created
             and is marked as invalid.
        
          6. Subsequently, when drawing is attempted in the base color (the
             pattern has PaintType 2), the code will note that the cache is
             not yet valid and invoke cie_joint_caches_init (gscie.c). This
             routine can do nothing, however, because the TransformPQR structure
             for the cie_render structure in the graphic state is set to
             TransformPQR_from_cache, indicating that the only data available
             for the TransformPQR procedure is in the (now invalidated) cache.
        
             As a fall-back, the CIE color is mapped to RGB by setting all
             components to 0, which yields the black output.
        
        The proper fix for this problem is re-designing both the CIE color space
        and the color rendering structures so that they retain enough information
        to regenerate the joint CIE cache when necessary. Since that is a big
        change, the attached modifications take the more modest approach of adding
        a "forcesetcolorspace" operator, which will set a color space even if it
        is identical to the current color space.
        
        Also included in the set of changes is a minor modification to gs_rectfill
        (gsdps1.c) that suppresses direct access to the device's fill_rectangle
        procedure if both overprint and overprint mode are true. Since
        overprintmode must be applied prior to halftoning, the code must be forced
        through one of the higher-level methods which include the pre-halftoned
        device color information.
        
        Modified files:
        
          lib/gs_cspace.ps
            Added the _setcolorspace procedure, which accepts both a boolean and
            a color space dictionary. If the boolean is true, the color space
            will not be set if it is the same as the current color space (via a
            conservative evaluation).
        
            The setcolorspace pseudo-operator now invokes _setcolorspace with the
            boolean operand set to true. A new operator, forcesetcolorspace,
            invokes _setcolorspace with boolean set to false.
        
          lib/gs_devn.ps
          lib/gs_icc.ps
          lib/gs_indxd.ps
          lib/gs_patrn.ps
          lib/gs_sepr.ps
            Replaced setcolorspace with forcesetcolorspace when setting a base or
            alternative color space. This is necessary due to some problems in the
            handling of the the joint CIE cache in the graphic library.
        
          src/gsdps1.c
            Modify gs_rectfill to suppress direct access of a device's
            fill_rectangle method if both overprint and overprint mode are set
            to true. This is required to make sure the overprint compositor has
            access to pre-halftoned device color information with which to
            implement overprint mode.

        * gs_ll3.ps [1.4] (+5 -1):
        Modified Files:
        
          lib/gs_ll3.ps
            Added code to create the setoverprintmode and currentoverprintmode
            operators.
        
          src/gconf.c
            Add the gx_compositor_list array, to list the set of compositor
            types compiled into the system. Also provided the gs_find_compositor
            procedure, to locate a compositor method vector based on its
            type identifier.
        
          src/gdevdgbr.c
            Fixed several bugs in gx_get_bits_copy, for cases in which the
            transfer of output data involves a skew (bit shift) but no color
            conversion (a case that is apparently used only by the overprint
            facility). This case uses the copy_mono method for the 1-bit
            memory device. The invocation of this method had two problems:
        
              1. The temporary device created for the transfer had uninitialized
                 width and height fields. Because copy_mono will invoke the
                 fit_copy macro, these fields must be set to reasonable values.
        
              2. The width passed to copy_mono must be bit-width, as the
                 method for a depth == 1 device is used. Previously, the
                 pixel width was used.
        
          src/gdevx.c
            Fixed a problem in x_copy_image. If the image passed to this routine
            contains more than one pixel, the colors_and and colors_or fields were
            not updated. Because these fields are only used for optimization, and
            properly updating them in this situation is potentially expensive,
            they are now just set to safe values (colors_and = 0;
            colors_or = (x_pixel)(-1)).
        
          src/genconf.c
            Added to "-comp" option to support construction of a list of
            compositors compiled into the system.
        
          src/gs.mak
            Added the SETCOMP and ADDCOMP macros, to provide access to the
            -comp option of genconf.c.
        
          src/gsalphac.c
            Exported the gs_composite_alpha_type structure, and added a compositor
            type identifier to this structure. Also modified the de-serialization
            (read) method for this size so that the data string provided be large
            enough but not necessarily exactly the right size, and to return the
            number of bytes actually read (or an error code).
        
          src/gscdefs.h
            Added a prototye for gs_find_compositor (see gconf.c above).
        
          src/gscolor.c
            Modified gx_set_device_color_1 to turn off overprint (and overprint
            mode).
        
          src/gsovc.c:
            1. Modified the de-serialization method (read) to return the number of
               bytes actually read (or an error code).
            2. Renamed gs_overprint_type to be gs_composite_overprint_type, so as
               to conform to the new convention for compositor names.
            3. For the overprint devices, set the get_xfont_procs, get_xfont_device,
               and text_begin methods to use the corresponding default methods,
               rather than the forwarding methods. Device-supported fonts are
               incompatible with overprint, as the required low-level calls may
               not be made. While the text_begin method is not itself a rendering
               method, it does record an imaging device, and this device must
               be the overprint device rather than the target device. If the
               forwarding text_begin method is used, the recorded imaging device
               would be the target device.
            4. Modified update_overprint_params to avoid use of the overprint
               devices for cases in which overprint is true, but all color
               components are to be drawn. Though the output is not changed, use
               of the non-overprint device improves performance in this case.
            5. Modified the default overprint compositor creation method
               (c_overprint_create_default_compositor) to ignore overprint
               requests if the current color model has only a single component.
               Overprinting can never have an effect in this situation, and
               avoiding these cases also avoids difficulties with mask caching
               devices (such as are used with the character cache).
        
          src/gsstate.c
            Modified gs_state_update_overprint to update the color model mapping
            procedures and unset the device color. Though updating the overprint
            status will never change the color model, the overprint devices
            require a special set of forwarding color model mapping procedures.
        
          src/gxclimag.c
            Implemented the clist_create_compositor procedure (the create_compositor
            method for the command list device).
        
          src/gxclpath.c
            Replaced the cmd_opv_put_params code (0xdf) with cmd_opv_extend. This
            code indicates that the subsequent byte should be read and interpreted
            as a command from the gx_cmd_ext_op enumeration. Currently, this
            enumeration has two elements, cmd_opv_ext_put_params (the put_params
            method) and cmd_opv_ext_create_compositor (the create_compositor
            method).
        
          src/gxclrast.c
            1. Made the code parsing changes required by the new cmp_opv_extend
               code (see gxclpath.h above).
            2. Added the read_create_compositor procedure, to interpret the
               cmd_opv_ext_create_compositor command.
        
          src/gxclutil.c
            Modified cmd_put_params for the new cmp_opv_extend/cmd_opv_ext_put_params
            coding techinque.
        
          src/gxcmap.c
            Modified gx_set_cmap_procs to handle devices that have no
            get_color_mapping_procs method (such as mask caching devices).
        
          src/gxcomp.h
            Added the comp_id field to the gs_composite_type_t structure. Also
            added macros for the alpha and overprint compositors (the only two
            compositors in the current system).
        
          src/gxoprect.c
            Fixed typo in pack_scanline_lt8: the source data pointer was not
            being advanced.
        
          src/gxoprect.h
            Fixed typo in RCS identifier comment.
        
          src/lib.mak
            1. Updated several dependency lists.
            2. Added code to generate the list of compiled compositors.
        

Tue Jun  4 05:00:00 2002 GMT        Henry Stiles    henrys@meerkat

        * gs_setpd.ps [1.5] (+5 -2), gs_init.ps [1.5] (+8 -3):
        code set from ORIMP to enable overprint and overprint mode.
        
        New Files:
        
          src/gxoprect.c
          src/gxoprect.h
            These files provide the low-level code for the fill_rectangle method
            of the overprint compositor device. There are three such procedures,
            which are used in different circumstances:
        
              gx_overprint_generic_fill_rectangle is always applicable, but is
                very slow as it must decode and re-encode the color for each pixel.
        
              gx_overprint_sep_fill_rectangle_1 is applicable to separable and
                linear color encodings whose depth is a divisor of
                8 * sizeof(mono_fill_chunk) = 32. This is always the
                case if depth <= 8. The code used in this case is, once past a
                large amount of setup, about as fast as can be achieved while
                using get_bits_rectangle.
        
              gx_overprint_sep_fill_rectangle_2 is applicable to all other
                separable and linear color encodings (all of which will have
                depth % 8 = 0). This uses a byte-wise method which is in principle
                slower than what could be achieved with a chunk-wise method, but
                is much easier to code in the general case (i.e.: for multiple
                possible depths). It will likely be faster in practice.
        
        Modified Files:
        
          lib/gs_init.ps
          lib/gs_setpd.ps
            Modified erasepage (and several other bits of code that erase the
            page) to turn off overprint before filling the page. This is necessary
            to preserve the meaning of erasepage.
        
          src/gsbitops.c
          src/gsbitops.h
            Added the bits_fill_rectangle_masked procedure, a generalization of
            the bits_fill_rectangle procedure that allows for a component mask.
            Also generalized bits_fill_rectangle (and bits_fill_rectangle_masked)
            to support depth > 8, so long as
            (8 * sizeof(mono_fill_chunk)) % depth = 0.
        
            Currently, bits_fill_rectangle_masked is used only by the overprint
            compositor device, but it can also be used by devices that can
            directly implement overprint (such as the memory device).
        
          src/gscdevn.c
            Modified check_DeviceN_component_names to initialize the
            component_map.sep_type field of the imager state to SEP_OTHER.
            Previously this field was not set for DeviceN color spaces, which
            confused some of the overprint code.
        
          src/gsovrc.c
            Implemented the real overprint_fill_rectangle procedures. As part of
            this work, added the local procedure swap_color_index, that swaps
            bytes in a color index as required to work with byte-oriented bitmaps
            on little-endian devices (only if depth > 8).
        
            Also fixed a parity bug in the creation of the retain_mask.
        
          src/gsovrc.h
            Fixed typo (/* $Id: History7.htm 12320 2011-03-30 08:51:40Z chrisl $Id: History7.htm,v 1.43 2005/10/07 18:35:12 ray Exp $ */).
        
          src/gxdcconv.c
            Modified color_rgb_to_cmyk to work if the imager state pointer
            operand is a null pointer. Note that in this case full undercolor
            removal and black generation will be performed, which is consistent
            with other such conversions in the code that do not have access to
            the imager state, but differs from the mapping used if the imager
            state is available but has no blackgeneration or undercolor removal
            map.
        
          src/lib.mak
            Added the gxoprect.$(OBJ) target and included this as a dependency
            in LIB4s. Also updated some other dependency lists.
        
        
        Additional file modified (not for overprint but needed for release):
        
          src/gdevdflt.c
            Added code to select a reasonable default value for the decode_color
            method, as this method is used extensively by the generic overprint
            implementation routines. The modifications are just a first pass to
            allow us to test the overprint code; they are not intended as a
            final solution.

        checkin for three separate code set releases from ORIMP, release
        notes follow in reverse chronological order.
        
        Notes:
        
         Modified files:
        
          gsstate.c
            Added code to ignore an error return from the create_compositor call
            in gs_state_update_overprint if the call was made to turn off
            overprint. This avoids errors for device configurations that do not
            (yet) support the create_compositor call, when running files that do
            not require overprint support.
        
          gsovrc.h
            Fixed a typo in a commment.
        
          gxclrast.c
            Fixed a re-entrancy problem in read_set_color_space that was introduced
            by the previous modification to this file.
        
          gsimage.c
            Added a comment concerning re-entrancy, and slightly modified another
            comment.
        
          gscspace.c
            Added some comments concerning re-entrancy.
        
        Notes:
        
        Modified Files:
        
          src/gsovrc.c
            Added full compositor device "plumbing". The overprint compositor
            now does all of the required device creation and setup work. The
            only piece still missing are implementations of the low-level
            rendering routines that actually implement overprint.
        
          src/gsptype1.c
          src/gsptype2.c
          src/gxcht.c
          src/gxdcolor.c
          src/gxdcolor.h
          src/gxht.c
          src/gxpcolor.h
            Added the method get_nonzero_comps to the gx_device_color_type_t
            structure (the gx_device_color methods). This method is used by
            the overprint code to determine which color component intensities
            have non-zero value, which must be known to implement overprint
            mode.
        
          src/gsovrc.h
          src/gscspace.c
            Changed the drawn_comps field of the gs_overprint_params_t
            structure from a byte array to a gx_color_index. This is a bit
            ugly, as the value is a bit map rather than an encoded color,
            but allows much simpler processing. (As in device colors, a
            gx_color_index is used because it is known to be large enough.
        
          src/lib.mak
            Updated dependency list for gsovrc.$(OBJ).
        
        Notes:
        
        New Files:
        
          src/gsovrc.c
            Implementation of the overprint compositor. For the moment, this is
            just a stub. This file will grow considerably in the next two releases.
        
        
          src/gsovrc.h
            Interface to the overprint compositor. This is in essentially final
            form, even though only a stub implementation of the compositor is
            available. This file also includes a lengthy comment describing when
            the compositor must be updated.
        
        
        Modified Files:
        
          lib/gs_ciecs2.ps
          lib/gs_ciecs3.ps
          lib/gs_cspace.ps
          lib/gs_devcs.ps
          lib/gs_devn.ps
          lib/gs_devpxl.ps
          lib/gs_icc.ps
          lib/gs_indxd.ps
          lib/gs_patrn.ps
          lib/gs_sepr.ps
            Incorporated an optimization of setcolorspace from the casper head.
            The optimization avoids setting the color space if it is the same as
            the current color space. gs_icc.ps also contains a fix for a bug
            in the handling of DataSources that are streams (rather than strings;
            Dan discovered and analyzed this bug).
        
            Note that this is a fairly complex optimization, and there were many
            problems with the head code that needed to be resolved. Among these
            were:
        
              1. An invocation of setcolorspace should always set the default
                 color for the operand color space, even if that color space is
                 identical to the current color space.
        
              2. If UseCIEColor is true, setcolorspace must be executed if
                 the operand color space involves device-specific color spaces.
                 This is because the Default{Gray,RGB,CMYK} instances of the
                 ColorSpace resource category may have changed.
        
              3. When UseCIEColor is changed from true to false in setpagedevcie,
                 the implicit initgraphics invocation must perform a setcolorspace
                 operation, even if the current color space is DeviceGray. This
                 is necessary to ensure that the un-substituted DeviceGray color
                 space is set as the current color space.
        
        
          lib/gs_init.ps
            In /showpage, replace the sequence "erasepage ... initgraphics" with
            "initgraphics 1 setcolor .fillpage 0 setcolor". This has the desired
            effect, and avoids two unnecessay invocations of setcolorspace.
        
        
          lib/gs_setpd.ps
            1. Modified the currentpagedevice pseudo-operator for cases in which
               the stored page device must be copied. Previously, the new copy
               was allocated in the current VM mode, which could cause
               invalidaccess errors if currentpagedevice was invoked while in
               global VM mode and composite objects stored in the page device
               dictionary were in local VM (this problem is present in the PS3
               FTS). The new code will allocate the copy in the save VM as the
               original dictionary.
        
            2. In setpagedevice, added code to set current color space to
               something other than DeviceGray if modification of the page device
               will set UseCIEColor to false. This is necessary for the
               setcolorspace optimization to function properly (see above).
        
            3. In the .postinstall pseudo-operator, replaced "erasepage initgraphics"
               with "initgraphics 1 setcolor .fillpage 0 setcolor". This avoids
               two unnecessary invocations of setcolorspace.
        
        
          src/gdevp14.c
            Added the pdf14_create_compositor method. This method will check if
            the compositor to be created is the overprint compositor. If so,
            the request to create the compositor will simply be ignored, as
            the gs_pdf14_device and its associated marking device must implement
            overprint directly.
        
        
          src/gscdevn.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for DeviceN color spaces.
        
        
          src/gscolor2.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for Indexed color spaces.
        
        
          src/gscpixel.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for DevicePixel color spaces.
        
        
          src/gscscie.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for CIEBased color spaces.
        
        
          src/gscsepr.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for Separation color spaces.
        
            3. Moved the gs_{set|current}overprint[mode] procedures to gsstate.c.
        
        
          src/gscsepr.h
            Moved prototypes for the gs_{set|current}overprint[mode] procedures
            to gsstate.h.
        
        
          src/gscspace.c
            1. Removed the color space equality check methods for the device-
               specific color spaces.
        
            2. Added the basic set_overprint procedures, to provide color-space
               specific setting of the overprint compositor.
        
            3. Modified the gs_cspace_{build|init}_Device{Gray|RGB|CMYK}
               procedures to use the same identifier for all instances of
               the parameterless color spaces (i.e.: all DeviceGray instances
               will have the same id, as will all DeviceRGB instances, but the
               id for any DeviceGray will differ from the id for a DeviceRGB
               instance). This enables an optimization in the gs_setcolorspace
               routine that had been lost in the previous code modification.
        
        
          src/gscspace.h
            Removed prototype for the gs_color_space_equal procedure.
        
        
          src/gsicc.c
            1. Removed the equality check method.
        
            2. Added the set_overprint method for ICCBased color spaces.
        
        
          src/gslib.c
            Modified test9 to explicitly reset the current color space; this
            is no longer done by gs_initgraphics.
        
        
          src/gspcolor.c
            Added set_overprint method for pattern color spaces, removed the
            equality check method.
        
        
          src/gsstate.c
            1. Added code to update the overprint compositor when the current
               color space, current device, overprint, or overprint mode
               settings change. Included in this change is code in gs_grestore_only
               that updates the overprint compositor as part of the grestore
               operation when this is required.
        
            2. Moved the gs_{set|current}overprint[mode] procedures to this file
               from gscsepr.c. This is more convenient for the new code, and
               gscsepr.c was never a particularly appropriate place for these
               routines.
        
            3. Modified gs_initgraphics to not reset the current color space or
               current color. For PostScript this must now be done in the
               PostScript code to properly handle color space substitution.
               Other clients that use this procedure (the XL interpreter is the
               only one (aside from gslib.c)) can easily reset these parameters
               as well.
        
        
          src/gsstate.h
            Moved prototypes for the gs_{set|current}overprint[mode] procedures
            here from gscsepr.h.
        
        
          src/gxccache.c
            Modified gx_image_cached_char to just return if the current color
            is a pure gx_no_color_index (transparent).
        
        
          src/gxcspace.h
            1. Removed the equality check method.
        
            2. Added the set_overprint method.
        
        
          src/gxipixel.c
            Modified the gx_image_enum_begin to allow the Decode array for
            imagemasks to have any two distinct numbers, rather than just 0 and
            1. This matches the behavior of all Adobe systems (though not the
            documentation), and avoids some spurious failures when running the
            FTS.
        
        
          src/gxpcmap.c
            Modified pattern_accum_copy_mono to just return if both the foreground
            and background colors are gx_no_color_index (transparent). If this is
            not done, the mask device's copy_mono procedure may generate an
            error when invoked (this is true for mem_mono_copy_mono).
        
        
          src/iutil.c
            Modified obj_eq to consider two 0-length arrays to be equal,
            irrespective of their type and their pointers (the latter aren't
            meaningful if the array length is 0). This matches the PostScript
            documentation and the behavior of Adobe systems. It also fixes
            some spurious failures in the FTS.
        
        
          src/lib.mak
            Added an entry for gsovrc (the overprint compositor), and updated
            various dependency lists.
        
        
          src/zfdcte.c
            Modified the DCTEncode procedure (zDCTE) to allocate the
            jpeg_compress_data and subsidiary memory structures in current VM.
            Previously these structures were allocated in gs_default_memory,
            which does not support garbage collection. Since the structures
            were subject to garbage collection and relocation, chaos could
            and, in the case of FTS file 119-28.ps, did ensue.
        
            Note that these structure must be allocated immovable, which
            requires a considerable amount of overhead when using VM. A better
            approach would be to allocate them in gs_default_memory, and use
            a more sophisticated structure descriptor for the stream_DCT_state
            structure (st_DCT_state).
        
        
          src/zgstate.c
            Slightly simplified zinitgraphics, and updated a comment in this
            procedure.
        
        
          src/zmisc.c
            Modified realtime operator to set a zero point at boot time. This
            avoids an annoying delay in running FTS panel 211-01 (206-01.ps).
        
        
          zpcolor.c
            Modified the pattern_paint_prepare procedure to use gs_setdevice_no_int
            rather than gx_set_device_only. It is not clear why the latter
            procedure was ever used in this location, and it is now important to
            use the former procedure so the overprint compositor may be properly
            updated.

        Overprint implementation (Jan Stoeckenius)
        
        This is a preliminary code release for the overprint capability. The
        release does not contain the overprint facility itself; it consists
        entirely of modifications so that color space changes will occur in a
        predictable fashion.
        
        Files removed:
        
          src/gshsb.c
          src/gshsb.h
          src/gscssub.c
          src/gscssub.h
          src/zhsb.c
        
        
        Files added:
        
          lib/gs_cspace.ps      PostScript portion of the basic color space handling;
                                see the extensive comment at the head of the file
                                for information. Note that color space substitution
                                and the hue-saturation-brightness (HSB) color space
                                are now fully implemented in the PostScript code;
                                the interpreter and the graphic library are no longer
                                involved in or even aware of these features.
        
          lib/gs_devcs.ps       Implementation of the DeviceGray, DeviceRGB, and
                                DeviceCMYK color spaces.
        
          lib/gs_ciecs2.ps      Implementation of the LangaugeLevel 2 CIEBased color
                                spaces: CIEBasedA and CIEBasedABC.
        
          lib/gs_ciecs3.ps      Implementation of the LanguageLevel 3 CIEBased color
                                spaces: CIEBasedDEF and CIEBasedDEFG
        
          lib/gs_devpxl.ps      Implementation of the DevicePixel color spaces
        
          lib/gs_indxd.ps       Implementation of the Indexed color space.
        
          lib/gs_sepr.ps        Implementaton of the Separation color space.
        
          lib/gs_devn.ps        Implementation of the DeviceN color space.
        
          lib/gs_patrn.ps       Implementation of the Pattern color space.
        
        
          lib/gs_img.ps         Implementation of the traditional (non-dictionary)
                                form of the image and imagemask operators, and the
                                colorimage operator (including the Next alphaimage
                                facility). The interpreter now provides only the
                                dictionary form of the image and imagemask operators,
                                including a variation that provides alpha-channel
                                support.
        
                                Also modified the handling of color spaces for
                                ImageType 2 images. This slightly changes the behavior
                                of these images. If PixelCopy is defined to be true
                                in the image dictionary but such a copy cannot be
                                supported, an error will be generated. This is in
                                agreement with Adobe's documentation, but differs
                                from the earlier behavior.
        
          The code for Indexed, Separation, and DeviceN color spaces
          incorporates code, courtesy of Dan, that will invoke the lookup or
          tint transform procedure in the appropriate context if this is
          appropriate (if there is a lookup procedure for Indexed color spaces
          or the alternate color space is in use for Separation and DeviceN
          color spaces). Currently this is not done recursively (if an Indexed
          color space has a DeviceN base color space, for example), but that
          has not proven necessary in practice. If necessary, it can be added.
        
        
          src/zcolor3.c         Code to implement the .setuseciecolor operator. This
                                operator is used only in the setpagedevice code, and
                                makes certain that the use_cie_color field in the
                                interpreter's graphic state mirrors the setting of
                                the UseCIEColor page device parameter.
        
        
        Files modified:
        
          lib/gs_dpnxt.ps       Added PostScript implementation of the alphaimage
                                operator. This uses the internal .alphaimage
                                operator, which is a variation of the image
                                operator that provide alpha-channel support.
        
          lib/gs_icc.ps         Rewritten to implement the ICCBased color space
                                in the new scheme. See the comments in
                                lib/gs_cspace.ps for information.
        
          lib/gs_init.ps        Modified to include gs_cspace.ps, gs_devcs.ps,
                                and gs_img.ps, and to remove img_util_dict and
                                .cspace_util_dict from userdict at the end of
                                initialization.
        
          lib/gs_lev2.ps        All explicit color spaces removed (with one
                                exception, and replaced by inclusion of gs_devpxl.ps,
                                gs_ciecs2.ps, gs_indxd.ps, gs_sepr.ps, and
                                gs_patrn.ps. The only remaining color space support
                                feature is moving the setcolorspace and setcolor
                                pseudo-operators, and the colorspacedict dictionary,
                                to level2dict. This must be done here, as it is not
                                known that level2dict exists when gs_cspace.ps is
                                first run.
        
                                Also removed all explicit image support. This is
                                now handled by gs_img.ps (see above).
        
          lib/gs_ll3.ps         Removed the old support for color space substitution;
                                this is now handled directly by the color space
                                code (see the comments in gs_cspace.ps for
                                information). Added inclusion of gs_ciecs3.ps and
                                gs_devn.ps.
        
          lib/gs_setpd.ps       Added support for the .getuseciecolor and
                                .setuseciecolor operators. This maintains a
                                "mirror" of the UseCIEColor parameter in the
                                graphic state, to allow fast access.
        
          src/gdevnfwd.c        In gx_forward_get_color_mapping_procs, added a check
                                for the case of a target device which has no
                                get_color_mapping_procs procedure. This led to a
                                segmentation violation crash for FTS file 296-01.ps
                                The fix may not be the correct one, as we are not
                                certain why a device would lack this method.
        
          src/gdevp14.c         Replaced a use of the shared field in the graphic state
                                with a color space allocated on the C-language stack.
        
          src/gdevpsdi.c        Replaced an instance of use of the gs_cspace_DeviceRGB
                                procedure.
        
          src/gscolor.c         Removed gs_currentgray and gs_currentrgbcolor. Modified
                                gs_setgray and gs_setrgbcolor to use gs_setcolorspace
                                and gs_setcolor. This eliminates use of the
                                gs_current_Device*_space routines.
        
          src/gscolor.h         Removed prototypes for gs_currentgray and
                                gs_currentrgbcolor.
        
          src/gscolor1.c        Removed gs_currentcmykcolor. Modified gs_setcmykcolor
                                to use gs_setgray and gs_setcolorspace.
        
          src/gscolor1.h        Removed prototype for gs_currentcmykcolor.
        
          src/gscolor2.c        Removed gs_currentcolorspace_index. Removed the color
                                index tracking used as part of the color space
                                substitution method.
        
          src/gscolor2.h        Removed prototype for gs_currentcolorspace_index.
        
          src/gscscie.c         Eliminated use of the gs_cspace_Device* routines.
        
          src/gscsepr.c         Fixed a pair of typos in revision 1.6 of the code.
                                In gs_cspace_set_sepr_proc and
                                gx_concretize_Separation, the code was still accessing
                                pcspace->params.device_n when it wanted to access
                                pcspace->params.separation. This caused a crash in
                                FTS file 245-01.ps.
        
          src/gscspace.c        Removed gs_cspace_Device* procedures.
        
          src/gscspace.h        Removed prototypes for gs_cspace_Device* procedures.
        
          src/gsimage.c         Removed use of the gs_cspace_DeviceGray procedure.
        
          src/gsiparam.h        Removed the gs_image_t_int_{gray, rgb, cmyk} macros.
        
          src/gsistate.c        Updated code to reflect removal of the shared field in
                                the imager state. As part of this, the
                                rc_free_imager_shared and gx_device_color_spaces_free
                                procedures were removed.
        
          src/gslib.c           Removed use of the gs_current_Device*_space and
                                gs_image_t_init_gray procedures.
        
          src/gspcolor.c        Removed reference to the orig_cspace_index field,
                                which is no longer part of the library's graphic
                                state.
        
          src/gsptype1.c        Eliminated use of the gs_cspace_DeviceGray procedure,
                                and insured that a color space is set as the current
                                color space before it is used.
        
          src/gsstate.c         Removed code that maintained the device_color_spaces
                                field (color space substitution), which is no longer
                                in the library's graphic state.
        
          src/gxclrast.c        Removed use of the gs_cspace_Device* procedures.
        
          src/gximage3x.c       Removed use of the gs_image_t_init_gray procedure.
        
          src/gximage2.c        Modified color space handling for ImageType 2 images.
                                Note that there was and still is a problem with the
                                handling of transformations in this code.
        
          src/gxistate.h        Removed the shared field of the imager state, all
                                associated structures and prototypes, and modified
                                the affected GC macros. The gx_device_color_spaces_t
                                structure was previously used in the graphic library's
                                state as well, but that use has been eliminated.
        
          src/gzstate.h         Removed the the device_color_spaces field, and modified
                                the requisite GC macros
        
          src/idparam.c         Modified dict_float_array_check_param to handle
                                packed (short or mixed) arrays.
        
          src/igstate.h         Added the use_cie_color field. This is a mirror for
                                the UseCIEColor parameter of the page device, used
                                because the currentpagedevice operator is potentially
                                expensive.
        
          src/iimage.h          Modified to restrict the interpreter to just the
                                dictionary form of the image and imagemask operator.
                                This removes the zimage_opaque_setup, zimage_data_setup,
                                and zimage_multiple prototypes, and moves the
                                image_params structure and the image1_setup
                                prototypes to this file (from iimage2.h).
        
          src/iimage2.h         Moved everything except the prototype for
                                process_non_source_image to iimage.h.
        
          src/iutil.c           Added process_float_array procedure, to allow packed
                                (short, mixed) arrays of numbers to be handled.
        
          src/iutil.h           Added prototype for the process_float_array procedure.
        
          src/zcolor.c          Removed:
                                  zcurrentgray, zcurrentrgbcolor,
                                  setgray, setrgbcolor
                                Moved (from zcolor2.c):
                                  zcurrentcolor, zcurrentcolorspace,
                                  zsetcolor, zsetcolorspace
                                Added:
                                  zgetuseciecolor   queries the use_cie_color field
                                                    in the interpreter state
                                  zsetdevcspace     sets a DeviceGray, DeviceRGB, or
                                                    DeviceCMYK color space
        
          src/zcolor1.c         Removed zcurrentcmykcolor, zsetcmykcolor, and
                                zcolorimage.
        
          src/zcolor2.c         Removed everything in prior version. Added
                                zusealternate, to test if an alternate color space
                                is being used (for a Separation, DeviceN, or ICCBased
                                color space), or if a base color space is in use
                                (for an Indexed or a Pattern color space that uses
                                a base space).
        
          src/zdpnext.c         Replace the alphaimage operator with .alphaimage,
                                which has the semantics of the dictionary form of
                                the image operator.
        
          src/zgstate.c         Modified the initgraphics operator to set the
                                colorspace.array field to a legitimate color space
                                (previously it was set to a null object). Also
                                inserted code to initialize the use_cie_color field
                                to false.
        
          src/zimage.c          Removed the traditional-form image and imagemask
                                operators (zimage and zimagemask), and moved the
                                dictionary form of these operators to this file
                                from zimage2.c. Also, added the has_alpha parameter
                                to the data_image_params and pixel_image_params
                                procedures, to support the .alphaimage operator.
        
          src/zimage2.c         Moved everything except the process_non_source_image
                                procedure to zimage.c.
        
          src/zimage3.c         Updated calls to data_image_params and
                                pixel_image_params to add has_alpha parameter.
        
          src/zmisc3.c          Removed .setsubstitutecolorspace operator.
        
          src/zpcolor.c         Modified .setpatternspace to handle a packed (short,
                                mixed) array operand.
        
          src/zshade.c          Modified build_mesh_shading to handle a packed (short,
                                mixed) DataSource array operand.
        
          src/ztrans.c          Modified calls to data_image_params and
                                pixel_image_params to add has_alpha operand.
        
          src/watclib.mak       Removed reference to the hsblib.dev, which no longer
                                exists and which, for some unknown reason, was directly
                                included in this makefile. Does anyone still use this
                                file?
        
          src/int.mak           Removed hsb.dev and the zimage2_l2 operators, added
                                zcolor3.c, updated various dependency lists.
        
          src/lib.mak           Removed hsblib.dev and gscssub.[ch], updated various
                                dependency lists. Note that this file has not yet
                                been modified to always compile with Level 3 support.

Version 7.22 (2002-08-06)




This release integrates the rewritten pdfwrite font copying code,
fixing a large class of pdfwrite bugs involving incremental font
updating. This project was completed before the DeviceN merge was
ready, so this release (rather than 7.21 as previously stated) is
the final checkpoint prior to the DeviceN merge. 



Overall, pdfwrite is probably an improvement over previous releases,
but there are still known issues. Testing of pdfwrite with real-world
files is encouraged.

The nightly regression tests show many changes. However, most of
the non-pdf regressions are tiny changes resulting in comparing a
debug build against a non-debug baseline. The rendering really
shouldn't be different at all, so we're leaving these regressions open
until we can fix the discrepancy. On the pdfwrite side, most of the
regressions are actually improvements, but there are some known
issues.  Notably, the "same_font" function is incorrect, and deriving
several fonts from a standard font, replacing Metrics or Metrics2
only, pdfwrite incorrectly merges them into a single font. This causes
a regression with 093-01.ps and probably other test files.

Upgrading ps2pdf.htm about pdfwrite/pdxtext. (doc/Ps2pdf.htm [1.44]:
2002/07/31 10:00:57 igor)

First commit in 7.22 release process: date and News updates.
(doc/News.htm [1.109]: 2002/08/06 23:10:40 raph)


Procedures

Fixes problems:
	- Renaming few variables in devs.mak for better clarity.
(devs.mak [1.68]: 2002/07/18 18:03:15 igor)
	- Changed make_two_versions to use the logging system.
(toolbin/tests/make_two_versions [1.5]: 2002/07/23 16:37:51 jack)
	- remove spurious build of the gtk client along with the macos
framework. (macos-fw.mak [1.5]: 2002/08/05 16:21:12 giles)

Bump version number to 7.22 as final commit in 7.21 process.
(version.mak [1.48]: 2002/07/09 07:42:10 raph)

Adds a procedure for testing whether a string was returned by
gs_c_glyph_name. Allows the font copying code to share these strings,
substantially reducing the load on the garbage collector.
(toolbin/encs2c.ps [1.3]: 2002/07/09 14:04:19 lpd)

Switching on the new pdfwrite/pdxtext code. (devs.mak [1.69]: 2002/07/26
07:27:19 igor)

First commit in 7.22 release process: date and News updates.
(version.mak [1.49]: 2002/08/06 23:10:40 raph)


Utilities

Changes all references to L. Peter Deutsch as the author of Ghostscript to
refer to artofcode LLC and Artifex Software as the maintainers of
Ghostscript. (lib/prfont.ps [1.6], lib/ps2epsi.ps [1.9]: 2002/07/11 02:54:22
lpd)


Drivers

Fixes problems:
	- When compiled for A4 default page size, the initial page size is
now 595x842pts. The initial printer page size in tenths of an inch now uses
floating point. This may cause problems with old compilers that do not allow
floating point calculations in initializers for integers. Add some casts to
suppress warnings with the MS compiler. Fixes SourceForge bug #535997,
"ps2pdf produces incorrect A4 page size". (gdevbmpc.c [1.5]: 2002/07/18
11:01:44 ghostgum)


PDF writer

Fixes problems:
	- Fixes the last (?) major batch of problems in the new pdfwrite
text code. We think this code is now good enough for general testing: search
for PDTEXT in src/devs.mak for information on how to enable it.
(gdevpdtc.c [1.6], gdevpdte.c [1.7], gdevpdtf.c [1.9], gdevpdti.c [1.4],

gdevpdtw.c [1.5]: 2002/07/09 14:29:35 lpd)
	- (pdfwrite) Enforce compression choice on end of image; do not
choose with zero output length. (gdevpdfj.c [1.22]: 2002/07/15 19:25:11
igor)
	- (pdfwrite) Fixing the image dimensions for the alternative
compression stream. Source Forge bug "[ 574865 ] ioerror only with
PDFSETTINGS=/screen" (gdevpdfi.c [1.40]: 2002/07/15 19:34:17 igor)
	- Always write FontBBox into CFF, even though the spec says it's
optional, to work around a problem when printing the resulting file with
Adobe Acrobat Reader 4 to HP PostScript printers. Source Forge bug "[ 578899
] Missing /FontBBox when converting to ps?" (gdevpdfe.c [1.18],

gdevpdfs.c [1.23], gdevpdtc.c [1.7]: 2002/07/19 14:51:27 igor)
	- Fixing an unbalanced '>>' in pdf_write_CIDSet().
(gdevpdtb.c [1.6]: 2002/07/20 08:21:37 igor)
	- (pdfwrite) Standard font names were erroneously suffixed. Source
Forge bug "[ 557024 ] (pdfwrite) Font display incorrect" This changes old
pdfwrite only. The new one was patched separately. (gdevpdff.c [1.31]:

pdfwrite/pdxtext: fixing the decision about font embedding for the case when
a source document uses both standard and non-standard fonts with same name.

pdfwrite/pdxtext: TJ arguments were computed without accounting Tc.
(gdevpdts.c [1.10]: 2002/07/25 19:11:38 igor)

pdfwrite/pdxtext: TJ arguments were inaccurately rounded.
(gdevpdts.c [1.11]: 2002/07/29 08:42:39 igor)

pdfwrite/pdxtext: (1) Widths were computed wrongly, (2) standard fonts
missed Widths. (gdevpdtw.c [1.6]: 2002/07/29 11:47:19 igor)


PDF Interpreter

Fixes problems:
	- When using -dUseCropBox, use an inherited CropBox. The previous
fix would only use a CropBox on the page being displayed.
(lib/pdf_main.ps [1.54]: 2002/07/18 10:46:06 ghostgum)
	- If a 'stream' operator was followed by whitespace before the EOL,
then the fileposition was not at the start of the data. Add logic to allow
for this and also add a pdfformaterror if the EOL was a <cr> without a
<lf>. Fixes SourceForge bug 567612 for Artifex customer #1.
(lib/pdf_base.ps [1.27]: 2002/07/31 19:06:11 ray)


Interpreter

Fixes problems:
	- (FAPI) server_font_data were prematurely reset in zFAPIpassfont.
Thanks for Graham Asher for spotting this. Also fixes minor bugs in
comments. (ifapi.h [1.12], zfapi.c [1.22]: 2002/07/09 14:55:03 igor)
	- Avoid opstack overflow by explicit array construction, rather than
unpacking and padding on the stack, for padding of glyphencoding array.
Fixes SF bug #576651. (lib/gs_ttf.ps [1.16]: 2002/07/10 06:29:34 raph)
	- Adobe renders marks outside the ImagingBBox and QuarkXPress relies
on this. Maintain the ImagingBBox of the page device at the PostScript level
independently from the device parameter. There is a slight incompatibility
if programs that set the ImagingBBox incorrectly relied on this causing
clipping, which is prohibited by the PLRM. Programs that wish to directly
set the ImagingBBox device parameter can still do so from C or from PS using
the .putdeviceprops GS private operator. Fixes SF bug 570829 for Artifex
customer #411. (lib/gs_setpd.ps [1.12]: 2002/07/10 23:05:59 ray)
	- Add a predefined ColorRendering Resource named
/DefaultColorRendering since this is the name that GetSubstituteCRD will
return and also is the name expected by some software. SourceForge bug
#570217 for cust #150. (lib/gs_res.ps [1.24]: 2002/07/12 06:46:33 ray)
	- Results of zchar_get_metrics2 were missinterpreted.
(zchar1.c [1.20]: 2002/07/16 16:47:39 igor)
	- correct the ISO paper sizes in gs_statd.ps to match those in the
Adobe PPD specification, technical note 5003. Fixes SourceForge bug #536877,
"Paper sizes wrong in gs_statd.ps". (lib/gs_statd.ps [1.9]: 2002/07/18
10:41:53 ghostgum)
	- The addition of the function sampling logic for DeviceN tint
transforms (fix 474544) tripped over a bogus assumption in Adobe Procset for
DuoTones generated by (at least) Photoshop. The assumption was that if the
alternate color space of a DeviceN space was being used, that the procedure
would run when 'setcolor' was executed and that the stack would be
accessible during that procedure. This fixes several bug reports with
'/stackunderflow in pop' errors including SF #549307, 576577 and 582385 for
Artifex customers. Thanks to Dan Coby for the analysis and fix.
(lib/gs_lev2.ps [1.20], lib/gs_ll3.ps [1.15], zcolor2.c [1.9]: 2002/07/31

Bump version number to 7.22 as final commit in 7.21 process.
(lib/gs_init.ps [1.58]: 2002/07/09 07:42:10 raph)

Previous commit was botched because of improperly removed debugging code.
Second commit for fix of SF #576651. (lib/gs_ttf.ps [1.17]: 2002/07/10

FAPI project : WMode 1 was wrongly processed for base fonts.
(zfapi.c [1.23]: 2002/08/03 15:50:51 igor)


Library

Fixes problems:
	- Fixes bugs in font copying (currently used only by the new
pdfwrite text code): TrueType glyphs with multiple names in CharStrings only
stored a single name; copied Encodings were initialized incorrectly to
.notdef rather than GS_NO_GLYPH; some of the procedures of copied TrueType
fonts weren't initialized correctly; 'seac' didn't copy the Encoding entries
for the components. Also shares the known glyph names when possible, to
reduce the load on the garbage collector. (gxfcopy.c [1.14],
gxfcopy.h [1.6]: 2002/07/09 14:26:45 lpd)
	- When compiled for A4 default page size, the initial page size is
now 595x842pts. The initial printer page size in tenths of an inch now uses
floating point. This may cause problems with old compilers that do not allow
floating point calculations in initializers for integers. Add some casts to
suppress warnings with the MS compiler. Fixes SourceForge bug #535997,
"ps2pdf produces incorrect A4 page size". (gdevprn.h [1.11],

	- (pdfwrite) Quiet Cygwin/gcc warnings. (gdevpsft.c [1.21]:

Bump version number to 7.22 as final commit in 7.21 process.

Version 7.21 (2002-07-08)




This is a reasonably stable development snapshot, the last before the
DeviceN work gets merged in. In particular, this version is probably
the most stable pdfwrite version to date.

Incompatible changes











Documentation

Fixes problems:
	- Changes the operation of AutoFilter{Gray,Color}Images to always
use the lossless filter (normally FlateEncode), rather than using DCTEncode
for 8-bit-per-component images at least 64x64 in size. While this isn't
optimal, it fixes a long-standing problem that many users have complained
about. Fixes SourceForge #450663. (doc/Ps2pdf.htm [1.41]: 2002/04/08
21:21:23 lpd)
	- The recently added reference to zcidtest.c had the correct text
but an incorrect URL. (doc/Develop.htm [1.73]: 2002/04/09 02:03:22 lpd)
	- the url for the guide to international paper sizes has changed.
Thanks to Nelson Beebe for finding the update. (doc/Use.htm [1.52]:
2002/04/14 01:08:14 giles)
	- The new file md5main.c was not included in the catalog of source
files. (doc/Develop.htm [1.74]: 2002/04/14 15:56:53 lpd)
	- More compatibility to Adobe interpreters in 'eexec'. This is
NON-BACKWARD-COMPATIBLE change. Now eexec skips all whitespaces at the
beginning of input stream, except for PFBDecode output. Thanks to L. Peter
Deutsch for participation. Source Forge bug "[ 428891 ] Undefined commands
interpreting Postscri". (doc/Language.htm [1.49]: 2002/05/01 23:15:23 igor)
	- pdfwrite relied on the PostScript interpreter to load and make
available the known encodings and glyph sets identified in src/gsccode.h.
With this change, pdfwrite can now be used without a PostScript interpreter,
and with fonts that do not implement the known_encode callback.
(doc/Develop.htm [1.78], doc/Psfiles.htm [1.32]: 2002/05/12 22:38:08 lpd)
	- Fixes a typo in, and slightly improves, documentation for invoking
cvs2hist as part of the release process. Fixes SourceForge #551275.
(doc/Release.htm [1.61]: 2002/06/26 20:14:45 lpd)
	- Fixes a typo in the reference to src/gdevpdte.c.
(doc/Develop.htm [1.83]: 2002/06/27 00:50:23 lpd)
	- Add the option -dUseCropBox to set the page size from the CropBox
rather than the MediaBox. This is appropriate when using ghostscript to view
PDF files or convert to bitmaps. It probably isn't appropriate for printing.
Fixes SourceForge bugs #522486, "Wromg size EPS generated from PDF" and
#538267 "Problems with Media Box in PDF and PS interpreter".
(doc/Use.htm [1.53]: 2002/06/28 10:55:43 ghostgum)

update version numbers after the 7.20 release. (doc/News.htm [1.104]:

gs-cjk project : add note about abandoning of CIDFnmap in gs6.53 and gs7.0x
to incompatible changes. (doc/News.htm [1.105]: 2002/04/04 06:01:51
mpsuzuki)

Changes gs_cmap_t (internal representation of CMaps) to an abstract
superclass with multiple implementations: standard Adobe CMapType 1,
TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
that composite fonts (including those based on TrueType Unicode fonts) with
Unicode-based CMaps are embedded in the PDF file with the original text
preserved and with an appropriate ToUnicode CMap, making the text searchable
in Acrobat. (doc/Develop.htm [1.72]: 2002/04/08 21:02:44 lpd)

Documents more clearly the fact that the ProcessColorModel parameter for
ps2pdf / pdfwrite does not affect (most) images. Also changes the "notes"
references from the parameter table to live links. (doc/Ps2pdf.htm [1.42]:
2002/04/09 22:43:46 lpd)

Documents a user request for pdfwrite to convert images to a fixed,
specified color space, as it currently does for vectors/text/masks.
(doc/Issues.htm [1.23]: 2002/04/09 22:51:20 lpd)

Add an example using .locksafe to permit reading of files anywhere while
preventing file writing, deleting or renaming (as with the pre 7.20 SAFER
mode). Related to SourceForge bug #541856. (doc/Language.htm [1.48]:
2002/04/11 18:11:02 ray)

Deletes "Vanilla" functions, which have not been used for a long time. They
were originally created for implementing FunctionType 4 functions using a
callback to the PostScript interpreter, but FunctionType 4 functions have
had their own interpreter since 3/19/2000 (first revision of gsfunc4.c).
(doc/Develop.htm [1.75]: 2002/04/19 00:53:19 lpd)

Documents the rationale for stable allocators better.
(doc/Develop.htm [1.77]: 2002/05/02 20:48:21 lpd)

Documents the fact that driver procedures other than put_params must not
reset is_open, and the invariant that requires any device instance
referenced from a graphics state to be open. (doc/Drivers.htm [1.29]:
2002/05/02 22:36:47 lpd)

Update the url for the zlib website and source. Fixes SF Bug #550585.

Encodings. (doc/Develop.htm [1.79], doc/Psfiles.htm [1.33]: 2002/05/14
23:33:57 lpd)

Refactors the pdfwrite driver so that none of the structures, and very few
of the procedures, for handling text and fonts are visible to the main body
of code, in preparation for a major rewrite of the text and font code.
(doc/Develop.htm [1.80]: 2002/05/20 07:07:15 lpd)

Update Release.htm with changes from the 7.05 release. Fixes SF bug #551275.

Adds references to new source files gxfcopy.c, gxfcopy.h, stdpn.h, and
zfctest.c. (doc/Develop.htm [1.81]: 2002/06/21 05:56:32 lpd)

Update for Borland 5.5 Compiler. Files changes include bcwin32.mak,
dwmainc.c, unistd_.h, bcc32.cfg and Make.htm. Patch by Rod Webster (rodw).
SF#559565 (doc/Make.htm [1.51]: 2002/06/24 06:20:25 jeong)

Adds a complete rewrite of the font and text code in pdfwrite, based on
copying fonts incrementally to stable memory rather than trying to deal with
fonts being freed at unpredictable times. Should fix a large number of
current SourceForge bugs when completed: however, the code is currently in
pre-alpha state and is not usable on any realistic input. The API is
compatible with the previous pdfwrite text code; the choice of which set to
use is controlled by a single, documented line in src/devs.mak.

Procedures

Fixes problems:
	- gscdef.c must contain a definition for GS_PRODUCT that matches the
definition used by the baseline. run_nightly now sets GS_PRODUCT to "AFPL
Ghostscript" correctly regardless of it's setting in the repository.
(toolbin/tests/run_nightly [1.4]: 2002/04/09 01:25:26 jack)
	- gscheck_pdfwrite.py was modeled after run_regression instead of
check_*.py. This corrects the script so that it follows the testing
conventions and also adds gscheck_all.py which will run every gscheck_*.py
test (of which currently there is only one).
(toolbin/tests/gscheck_all.py [1.1],
toolbin/tests/gscheck_pdfwrite.py [1.2], toolbin/tests/gstestgs.py [1.7]:
2002/04/09 21:45:33 jack)
	- Fix for #540871. Clean up compiler warnings in zfsample.c. Note:
The addition of two include files in zfsample.c forces a change in
dependencies in int.mak. (int.mak [1.70]: 2002/04/11 02:18:14 dan)
	- Indexed color spaces weren't implemented for ShadingType 4-7
shadings. (lib.mak [1.73]: 2002/04/14 04:30:47 lpd)
	- Options specified in gsconf.py were not being used correctly by
all scripts. run_regression and revert_baseline were both broken in this
respect. (toolbin/tests/gstestgs.py [1.8],
toolbin/tests/revert_baseline [1.5], toolbin/tests/run_regression [1.4]:
2002/04/16 21:06:20 jack)
	- missing space bofore the gsoptions are passed.
(toolbin/tests/gstestgs.py [1.9]: 2002/04/16 21:22:25 jack)
	- make symlinks to equivalent manpages with relative rather than
absolute paths to facilitate moving the directory to another location.
Closes SourceForge Bug #416131. (unixinst.mak [1.25]: 2002/04/18 01:53:36
giles)
	- the uniprint driver wasn't being included due to a typo.
(os2.mak [1.25]: 2002/04/19 00:56:28 giles)
	- Adds -p parameter to mkdir to suppress warning messages when the
target already exists and to create parent directories automatically if they
don't exist. Fixes Sourceforge bug #518742. (unix-dll.mak [1.9],
unixinst.mak [1.26]: 2002/04/19 01:08:38 jack)
	- Add PostScriptLevel3 as one of the Resources of the /Emulator
category so that it shows up with "gs -h". Fixes SourceForge bug #549235.
(int.mak [1.74]: 2002/04/26 20:51:24 ray)
	- Removing the variable $(PSD) from lib.mak to allow graphics
library to build independently on GS. (lib.mak [1.77]: 2002/05/05 13:44:27
igor)
	- The GS lib would not build. This fix corrects two minor problems.
The routine gs_abort was added to gslib.c. The unused include file
gmorecfg.h was removed from vdtrace.c. (lib.mak [1.78]: 2002/05/08 05:41:44
dan)
	- pdfwrite relied on the PostScript interpreter to load and make
available the known encodings and glyph sets identified in src/gsccode.h.
With this change, pdfwrite can now be used without a PostScript interpreter,
and with fonts that do not implement the known_encode callback.
(devs.mak [1.60], lib.mak [1.80]: 2002/05/12 22:38:08 lpd)
	- The rule for building icc.o didn't depend on $(ECHOGS_XE), causing
the build to possibly fail (depending on the order in which `make' built
targets) if executed with empty output directories. (icclib.mak [1.7]:
2002/06/05 19:55:04 lpd)
	- update_baseline had a typo for the baseline log file.
(toolbin/tests/update_baseline [1.6]: 2002/06/13 20:49:34 jack)
	- Limit the number of %disk devices to 7 to prevent problems with
the Dynalab font installer. Also return %disk devices in numeric order from
devforall and suppress %disk devices from filenameforall to match Adobe.
Also correct documentation of devforall (no pattern string used). Thanks to
Nori Matsushima and Erik Strik for testing of this feature (diskn.dev).
(int.mak [1.76]: 2002/06/14 04:04:39 ray)
	- .pushpdf14devicefilter was defined in zdfilter.c, but depended on
the optional pdf module's transparency features. Moves the definition of
this routine to the conditionally included ztrans.c. Fix by L. Peter
Deutsch, resolves SourceForge Bug 565019. (int.mak [1.77]: 2002/06/14
09:42:54 giles)
	- The automatically generated files src/gscedata.[ch] didn't have a
RCS Id line. (toolbin/encs2c.ps [1.2]: 2002/06/14 13:31:53 lpd)
	- As a result of a recent fix, an opdef table had more than 16
entries, causing initialization to abort. (int.mak [1.78]: 2002/06/14
14:17:56 lpd)
	- Fixes an oversight that prevented compilation with stdpn.h
included. (jpeg.mak [1.7]: 2002/06/16 09:11:47 lpd)
	- Implementing pdfmark stream compression. Source forge bug "[
558476 ] file attachment annotation uncompressed". (devs.mak [1.63]:
2002/06/16 22:07:55 igor)
	- Fixes minor errors in the makefile dependency lists. (The
dependency list for gxclrast.c, in particular, had gotten badly mangled.)
(lib.mak [1.86]: 2002/06/19 15:34:01 lpd)
	- Fixes an omission in a dependency list. (int.mak [1.79]:
2002/06/19 15:36:45 lpd)
	- Fixes another omission in a dependency list. (int.mak [1.80]:
2002/06/19 15:37:20 lpd)
	- pdfinflt.ps should not propagate the /Prev from the input file's
trailer since the output will only have a single xref table. Also add
'whitespace' after a stream before 'endstream' in case the input stream did
not have trailing whitespace (prevents /undefined errors).
(toolbin/pdfinflt.ps [1.4]: 2002/06/19 20:13:05 ray)
	- When building an archive of the graphics library or interpreter,
add only the object files, not the .dev and interpreter files. Fixes
SourceForge bug # 538311 - files missing from library archive.
(gs.mak [1.14], ugcclib.mak [1.19], unixlink.mak [1.6]: 2002/06/22 03:33:12
ghostgum)
	- gxfcache.h didn't #include or define all of its prerequisites.
(lib.mak [1.89]: 2002/06/24 05:14:15 lpd)
	- MSVC can't handle a makefile that compiles two sets of code with
some of the same exported names, but only linked in one set. The fix still
requires a 1-line edit of devs.mak when using MSVC. (devs.mak [1.67]:
2002/07/07 15:54:23 lpd)

update version numbers after the 7.20 release. (version.mak [1.46]:
2002/04/04 03:14:03 giles)

Changes gs_cmap_t (internal representation of CMaps) to an abstract
superclass with multiple implementations: standard Adobe CMapType 1,
TrueType 16-bit cmap (Platform 3, Encoding 1, Format 4), and one-for-one.
Adds the ability to designate a CMap as Unicode-based. Enhances pdfwrite so
that composite fonts (including those based on TrueType Unicode fonts) with
Unicode-based CMaps are embedded in the PDF file with the original text
preserved and with an appropriate ToUnicode CMap, making the text searchable
in Acrobat. (devs.mak [1.57], int.mak [1.69], lib.mak [1.70]: 2002/04/08
21:02:44 lpd)

Adds gscheck_pdfwrite.py and a new test class, GSFuzzyCompareTest. This test
does fuzzy compares of ps->raster and ps->pdf->raster to help
ensure the pdfwrite device is functioning properly.

Moves the remaining CID-related test operator (.writefont9) to zcidtest.c.
(int.mak [1.71], lib.mak [1.71]: 2002/04/11 22:07:36 lpd)

Create a separate WARNOPT parameter for specifying the warning message
level. This allows the message level to be specified from the command line.

(devs.mak [1.59]: 2002/04/14 06:55:58 lpd)

Adds a --[no-]pause switch to suite.tcl, for viewing suite output on the
display. Also changes the output file names from
t.<<date>>.<<page#>>.<<format>> to
<<filename>>.<<page#>>.<<format>>.
(toolbin/suite.tcl [1.6]: 2002/04/15 23:59:20 lpd)

Deletes "Vanilla" functions, which have not been used for a long time. They
were originally created for implementing FunctionType 4 functions using a
callback to the PostScript interpreter, but FunctionType 4 functions have
had their own interpreter since 3/19/2000 (first revision of gsfunc4.c).
(lib.mak [1.74]: 2002/04/19 00:53:19 lpd)

Add the ijs device to the default unix-gcc build. (unix-gcc.mak [1.33]:
2002/04/19 00:54:31 giles)

Adds a make_scaled virtual procedure to Function objects, to create a
modified Function whose N output values are transformed linearly according
to a supplied set of N range parameters. This is the first installment for
implementing conversion of extended-range CIEBased color spaces to ICCBased
spaces in pdfwrite. (lib.mak [1.75]: 2002/04/19 01:17:53 lpd)

Puts dpsand2.dev first in the dependencies of psl2.dev, so that (eventually)
geninit will have earlier access to the system name table for producing
output with binary token encodings. (int.mak [1.73]: 2002/04/19 19:22:14

Simplifies the C implementation of the known Encodings, and makes it conform
better to Ghostscript standard coding style. (devs.mak [1.61],
lib.mak [1.81], toolbin/encs2c.ps [1.1]: 2002/05/14 23:33:18 lpd)

Removes an extraneous makefile dependency. (lib.mak [1.82]: 2002/05/15
19:07:32 lpd)

Refactors the pdfwrite driver so that none of the structures, and very few
of the procedures, for handling text and fonts are visible to the main body
of code, in preparation for a major rewrite of the text and font code.
(devs.mak [1.62]: 2002/05/20 07:07:15 lpd)

Cleans up a number of design problems in the font callback procedures: 1)
Eliminates the gx_xfont_callbacks structure entirely. The known_encode
procedure is no longer needed: the new facilities in gscencs.[hc] make it
unnecessary, and none of the three implementors of the xfont interface use
it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
change for all clients of the glyph_name and known_encode procedures (of
which there are, respectively, 11 and 0 in the current code base), and for
all places that define gs_font_procs structures statically or initialize the
callbacks dynamically (of which there are currently only two, one in
gsfont.c and one in zbfont.c). There are also 3 identical places in the
GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
minor changes, with a small net reduction in code. 2) Deletes the
char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
three current xfont implementations implements it. 3) Changes the
char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
callback procedure, it takes a const gs_string * argument that is the actual
glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
(At present, there are 3 implementors, none of which use the glyph_name
callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
procedure, which is still required for other purposes, to gs_font_procs,
changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
clients, but they must already change because of item (1) above. 5)
Eliminates the registered_Encodings array in the PostScript interpreter,
substituting the C representation of the known Encodings. (int.mak [1.75],
lib.mak [1.84]: 2002/06/09 23:08:23 lpd)

Moves the now-unused Pn macros to a separate file, which now can easily be
commented out and eventually removed. (lib.mak [1.85]: 2002/06/16 08:57:57

Adds support for incremental font copying, currently required only by the
new pdfwrite text code. (int.mak [1.81], lib.mak [1.87]: 2002/06/19 15:52:29

SF#559565 (bcc32.cfg [1.2], bcwin32.mak [1.19]: 2002/06/24 06:20:25 jeong)

Adds a complete rewrite of the font and text code in pdfwrite, based on
copying fonts incrementally to stable memory rather than trying to deal with
fonts being freed at unpredictable times. Should fix a large number of
current SourceForge bugs when completed: however, the code is currently in
pre-alpha state and is not usable on any realistic input. The API is
compatible with the previous pdfwrite text code; the choice of which set to
use is controlled by a single, documented line in src/devs.mak.
(devs.mak [1.65]: 2002/06/25 01:51:32 lpd)

gs_exit() cleanup. gs_exit() is renamed gs_to_exit() since it is an about to
terminate cleanup function, it always returns. Both gs_to_exit() and
gs_abort are client provided functions. The client can have its own special
cleanup on exit, and the client can decide what it wants to do in the abort
case: exit, setjump/longjump, ... gp_do_exit() is the way for the client to
call a system independent exit() this allows for different exit codes on
unix and vms for instance. Only the client can call this, if so desired from
their gs_abort(). (bench.c [1.7], gp_dvx.c [1.7], gp_iwatc.c [1.9],

Drivers

Fixes problems:
	- Changes the operation of AutoFilter{Gray,Color}Images to always
use the lossless filter (normally FlateEncode), rather than using DCTEncode
for 8-bit-per-component images at least 64x64 in size. While this isn't
optimal, it fixes a long-standing problem that many users have complained
about. Fixes SourceForge #450663. (gdevpsdi.c [1.19]: 2002/04/08 21:21:21

cleanup on exit, and the client can decide what it wants to do in the abort
case: exit, setjump/longjump, ... gp_do_exit() is the way for the client to

Cleans up a number of design problems in the font callback procedures: 1)
Eliminates the gx_xfont_callbacks structure entirely. The known_encode
procedure is no longer needed: the new facilities in gscencs.[hc] make it
unnecessary, and none of the three implementors of the xfont interface use
it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
change for all clients of the glyph_name and known_encode procedures (of
which there are, respectively, 11 and 0 in the current code base), and for
all places that define gs_font_procs structures statically or initialize the
callbacks dynamically (of which there are currently only two, one in
gsfont.c and one in zbfont.c). There are also 3 identical places in the
GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
minor changes, with a small net reduction in code. 2) Deletes the
char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
three current xfont implementations implements it. 3) Changes the
char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
callback procedure, it takes a const gs_string * argument that is the actual
glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
(At present, there are 3 implementors, none of which use the glyph_name
callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
procedure, which is still required for other purposes, to gs_font_procs,
changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
clients, but they must already change because of item (1) above. 5)
Eliminates the registered_Encodings array in the PostScript interpreter,
substituting the C representation of the known Encodings.

PDF writer

Fixes problems:
	- Fix : pdfwrite wrongly computed text width for fonts with unusual
font matrix. Source Forge bug "[ 535401 ] euro glyph misplaced after
pdfwrite". (gdevpdff.c [1.27], gdevpdfs.c [1.14]: 2002/04/11 15:59:19 igor)
	- pdfwrite only updated the overprint flag in the graphics state for
fill and stroke, not for images. Fixes SourceForge #525712.
(gdevpdfg.c [1.18]: 2002/04/12 19:28:15 lpd)
	- Adding any of the base 14 fonts to the NeverEmbed list produced
broken output in PDF level 1.3 and above. Makes the 'default', 'screen', and
'ebook' parameter sets not embed the base 14 fonts. (The documentation
already said this was the case, even though it wasn't.) This is a partial
fix for SourceForge bug #438957. (gdevpdff.c [1.28]: 2002/04/12 19:38:33
lpd)
	- If a shading's Function entry was an array of functions rather
than a single function, pdfwrite wrote out an invalid Function object with a
FunctionType of -1. (gdevpdfu.c [1.23]: 2002/04/14 06:51:45 lpd)
	- pdfwrite would incorrectly output CalGray or CalRGB color spaces
even if the range of the color space was not [0 1] or [0 1 0 1 0 1]
respectively. (gdevpdfc.c [1.24]: 2002/04/14 07:09:51 lpd)
	- Fix : pdfwrite wrongly computed line width for fonts with
PaintType 2. (gdevpdfs.c [1.15]: 2002/04/16 10:18:59 igor)
	- When pdfwrite wrote out a fill with an uncolored (mask) Pattern,
all colors other than black were converted to white. (Bug found during
unrelated pdfwrite development.) (gdevpdfb.c [1.10]: 2002/04/29 04:32:32
lpd)
	- pdfwrite could not convert a CIEBased color space with input
domains larger than [0..1] to an ICCBased space, because the ICC profile
specification inherently limits inputs to this range. The fix required
explicitly rescaling the decoding of the color data in many different places
when such a color space was involved: the Decode arrays in images; the
tintTransform functions for Separation and DeviceN color spaces; the
Background, Function, and Decode for shadings. While this was only a
performance problem, it could be a very severe one, because it caused images
using such extended-domain CIEBased spaces to revert to zillions of tiny
rectangles. This change completes the ability of pdfwrite to convert
PostScript color spaces, aside from DeviceN and Separation spaces which are
the subject of a separate project. (gdevpdfb.c [1.11], gdevpdfc.c [1.26],

	- If a Type 1 font had an initial FontMatrix other than [0.001 0 0

Cleans up a number of design problems in the font callback procedures: 1)
Eliminates the gx_xfont_callbacks structure entirely. The known_encode
procedure is no longer needed: the new facilities in gscencs.[hc] make it
unnecessary, and none of the three implementors of the xfont interface use
it. See below regarding glyph_name. This is a NON-BACKWARD- COMPATIBLE
change for all clients of the glyph_name and known_encode procedures (of
which there are, respectively, 11 and 0 in the current code base), and for
all places that define gs_font_procs structures statically or initialize the
callbacks dynamically (of which there are currently only two, one in
gsfont.c and one in zbfont.c). There are also 3 identical places in the
GhostPCL code (in plfont.c, plffont.c, and plufont.c) that will require very
minor changes, with a small net reduction in code. 2) Deletes the
char_xglyph2 procedure from gx_xfont_procs. It is optional, and none of the
three current xfont implementations implements it. 3) Changes the
char_xglyph procedure in gx_xfont_procs so that instead of a glyph_name
callback procedure, it takes a const gs_string * argument that is the actual
glyph name (if the glyph is not gs_no_glyph and is not a CID). This is a
NON-BACKWARD-COMPATIBLE change for both clients and implementors of xfonts.
(At present, there are 3 implementors, none of which use the glyph_name
callback, and a single client call in gxccache.c.) 4) Moves the glyph_name
procedure, which is still required for other purposes, to gs_font_procs,
changing its declaration to int (*glyph_name)(gs_font *font, gs_glyph glyph,
gs_const_string *pstr); This is a NON-BACKWARD-COMPATIBLE change for
clients, but they must already change because of item (1) above. 5)
Eliminates the registered_Encodings array in the PostScript interpreter,
substituting the C representation of the known Encodings.

Adds stubs for the new PDF 1.4 pdfmark types, and clearly marks all
unimplemented pdfmark types as such. (gdevpdfm.c [1.20]: 2002/06/12 23:26:54
lpd)

Implements the /APPEND pdfmark. (gdevpdfm.c [1.21]: 2002/06/12 23:42:30 lpd)

Workaround for unimplemented NI, to avoid later typechecks on .PUTDICT. This
patch adds the dictionary cos object, but does not push it in a namespace to
be popped on occurrence of an image, as defined in section 6.2 of the
pdfmark reference (TN 5150). Allows test file of SourceForge bug #567653 to
run to completion. (gdevpdfm.c [1.22]: 2002/06/13 00:17:53 raph)

Adds two new procedures to pdfwrite's Cos object package, to support
namespaces and /NI pdfmark. (gdevpdfo.c [1.15], gdevpdfo.h [1.12]:
2002/06/13 20:40:30 lpd)

Implements namespaces (/NamespacePush, /NamespacePop pdfmarks) and the /NI
pdfmark for named images. Fixes SourceForge #567653, replacing the
workaround in revision 1.22 of src/gdevpdfm.c. (gdevpdf.c [1.46],

gdevpdfx.h [1.49]: 2002/06/24 05:35:59 lpd)

Adds a complete rewrite of the font and text code in pdfwrite, based on
copying fonts incrementally to stable memory rather than trying to deal with
fonts being freed at unpredictable times. Should fix a large number of
current SourceForge bugs when completed: however, the code is currently in
pre-alpha state and is not usable on any realistic input. The API is
compatible with the previous pdfwrite text code; the choice of which set to
use is controlled by a single, documented line in src/devs.mak.

In the new pdfwrite text code, fixes bugs and adds new logic for handling
encoded (Type 1/2 and TrueType) fonts. The code now handles simple fonts of
these types. (gdevpdtb.c [1.2], gdevpdtc.c [1.3], gdevpdtd.c [1.2],

PDF Interpreter

Fixes problems:
	- Remove "/tfopdict undef". tfopdict was defined in v.6.01 but the
definition was since removed. Fix for bug #511232 by Alex Cherepanov.
(lib/pdf_draw.ps [1.44]: 2002/04/10 02:23:08 ray)
	- Handle Widths and Encoding arrays in PDF Font objects that are too
small by using reasonable defaults. Adobe Acrobat Reader handles files with
these problems. Fix for Artifex customer 861 for SourceForge bug#538398.
(lib/pdf_font.ps [1.32]: 2002/04/10 15:16:00 ray)
	- Annotations with empty AP dictionary caused a failure. Providing
more tolerance rather such APs are invalid. Source Forge bug "[ 538428 ]
empty appearance streams". (lib/pdf_draw.ps [1.45]: 2002/04/29 09:59:27
igor)
	- More tolerance to inconsistent stream length in PDF reader. Source
Forge bug "[ 538042 ] /syntaxerror in --token--". (lib/pdf_base.ps [1.21]:
2002/04/30 10:46:20 igor)
	- More compatibility to Adobe interpreters in 'eexec'. This is
NON-BACKWARD-COMPATIBLE change. Now eexec skips all whitespaces at the
beginning of input stream, except for PFBDecode output. Thanks to L. Peter
Deutsch for participation. Source Forge bug "[ 428891 ] Undefined commands
interpreting Postscri". (lib/pdf_font.ps [1.33]: 2002/05/01 23:15:23 igor)
	- Make PDF reader tolerant to singular matrix in Tj. Source Forge
bug "[ 538055 ] /undefinedresult in --currentpoint--". (The solution was
suggested by L. Peter Deutsch.) (lib/pdf_ops.ps [1.24]: 2002/05/08 15:51:58
igor)
	- Acrobat Reader apparently ignores or clamps 'setflat' parameter
values when rendering PDF. This change emulates that behaviour by clamping
the flatness parameter to a max of 1. Fixes SourceForge bug #555657 for
Artifex customer #150. (lib/pdf_draw.ps [1.46]: 2002/05/22 17:29:37 ray)
	- GS doesn't process PDF files without the required key /FontName in
FontDescriptor dict. Adobe Acrobat Reader handles these out of spec files,
so we also allow this. To fix this, now uses /BaseFont key when /FontName is
missing. SF#515475. (lib/pdf_font.ps [1.34]: 2002/05/30 03:32:03 jeong)
	- Acrobat Reader apparently processes badly formed numbers that have
a '-' after the '.' by ignoring the fraction. If this type of tokenerror is
detected, issue an error message and change the scanning rules to do the
same as Adobe. SourceForge bug #558473 for Artifex customer #561.
(lib/pdf_base.ps [1.22]: 2002/05/31 17:14:34 ray)
	- Yet another change to allow our PDF intperpreter to tolerate an
out of spec PDF file that Acrobat Reader (and Glance pdf tools) handle. This
file had an 'endobj' without an 'endstream' terminating a stream. Fixes SF
bug #570262 for Artifex customer #1060. (lib/pdf_base.ps [1.23]: 2002/06/18
05:37:05 ray)
	- Correct the pdfformaterror message issued when an 'endobj' is seen
instead of 'endstream' and add a comment in the file about the error. Thanks
to Dan Coby for the suggestions improving the previous patch.
(lib/pdf_base.ps [1.24]: 2002/06/18 06:29:21 ray)
	- Use actual white point in /Lab spaces, rather than relying on
default. Fixes problem in regression file test.pdf. (lib/pdf_draw.ps [1.47]:
2002/06/20 20:26:48 raph)
	- Prevents /typecheck in --length-- if
