Version 8.63 (2008-08-01)
This is the fourth scheduled release in the stable Ghostscipt 8.6x
series. It corresponds to the 1.53 release of GhostPDL.
Approximately 238 bugs have been fixed since version 8.62. Of particular
note are robustness and performance improvements with large files,
invalid PDF, and font handling.
The major new feature of this release is multithreaded rendering. This
can be requested by passing -dNumRenderingThreads=n on
the command line. The input document is first parsed, and then each page
is split into n bands which are rendered concurrently. This
can provide a significant reduction in processing time on multi-core
systems.
Images are now always interpolated in their source colorspace. This
improves correctness for XPS documents and avoids bypassing the custom
color management callbacks for interpolated images. Interpolation and
color management are both expensive operations, so this affects
performance with large images. The effect can be positive or negative
depending on the file and the target resolution. If performance is a
problem, we suggest running with -dNOINTERPOLATION.
Support for OpenPrinting Vector devices has been upgraded to version
1.0.
There are two new devices in this release, both experimental. Behdad
Esfahbod has contributed a cairo output device which uses
the cairo graphics library to
generate PDF, SVG, EPS, or PNG files, based on the requested filename
extension. The svgwrite device directly outputs Scalable Vector
Graphics, the W3C XML vector graphics format. Both support only vector
art at this point; text and images will not be represented efficiently.
The following bugs were
open at the time of release:

Incompatible changes
The maximum number of color components has been reduced to 8 (from 252)
as a performance improvement. Eight is the largest number commonly used
and the largest number for which we support continuous tone images.
Users with special needs can restore the previous behavior by setting
the GS_CLIENT_COLOR_MAX_COMPONENTS preprocessor symbol to the required
number of components at compile time.
The -Z: debugging option now uses 'realtime' instead of 'usertime'
when reporting timing information on unix-like systems. This has
always been the case on windows-like systems.
Obsolete makefiles for the DesqView environment have been removed.

Fix problem with NumRenderingThreads>0 with devices that request data from

[src/gxclthrd.c]
2008-07-29T19:11:31.677116Z Alex Cherepanov
Add support to NULL pointers in t_structs or t_astructs objects to execstack
operator. Thanks to Ken for the analysis. Bug 689535.
DETAILS:
The issue is to do with devices handling patterns as high-level objects, which
is why it affects pdfwrite (which can handle patterns itself) but not regular
rendering. In zpcolor.c, pattern_paint_prepare(), there are two control paths,
one for devices which handle patterns as high-level objects, and one for
devices which don't. If the device can't handle high level objects, we install
a pattern accumulation device.
In this case, the flag internal_accum is set, we create the pattern accumulator
device and open it:
if (internal_accum) {
gs_memory_t *storage_memory = gstate_pattern_cache(pgs)->memory;
pdev = gx_pattern_accum_alloc(imemory, storage_memory, pinst,
"pattern_paint_prepare");
if (pdev == 0)
return_error(e_VMerror);
code = (*dev_proc(pdev, open_device)) ((gx_device *) pdev);
...
...
}
Later the two control paths rejoin and we put some objects on the execution
stack:
push_mark_estack(es_other, pattern_paint_cleanup);
++esp;
make_istruct(esp, 0, pdev);
Now notice that we construct the structure on esp using pdev, but we *don't*
create pdev if we can handle patterns, so its left as NULL and we end up
pushing an empty t_struct.
Leo's question in comment 10 is whether this is legal, the answer appears to be
yes, but its debatable.
In pattern_paint_finish we do this:
gx_device_forward *pdev = r_ptr(esp - 1, gx_device_forward);
if (pdev != NULL) {
gx_color_tile *ctile;
int code = gx_pattern_cache_add_entry((gs_imager_state *)igs,
pdev, &ctile);
That is, if the structure *isn't* NULL we do something with it, we ignore it if
it is NULL. Either way we then do this:
esp -= 3;
Removing all the objects from the execution stack that we added. Notice that
the structure we pushed onto the execution stack isn't actually 'executed', its
just data used by the pattern handler.
Now, all this works just fine in normal practice, however the job here uses a
CIEBased colour space, and being from an Adobe application it tries to set the
ColorRendering. Since we don't implement a ColorRendering resource category,
this causes an error (handled in a stopped context).
The default error handler uses execstack, and this is where the actual error
finally occurs, because execstack can't handle the empty structure.

2008-07-28T12:01:51.595271Z Alex Cherepanov
Fix extraction of the default subfile from PDF file collection on save
level 0. Export the file name as a PS name from PDF interpreter instance
to protect the name from restore. Bug 689981.
DETAILS:
Exporting this value as a global composite object doesn't work when PDF
interpreter runs on the save level 0. If we ever implement processing of
multiple files from PDF collection the interface will need some changes.

Fix (printer) : A check for buffer space overflow was dramatically overestimated.
DETAILS :
In the old code :
new_height < max_ulong/(mem_space + (new_height * pdf14_trans_buffer_size))
Where pdf14_trans_buffer_size is (raster * NUM_PDF14_BUFFERS).
equivalent to :
new_height * (mem_space + (new_height * (raster * NUM_PDF14_BUFFERS))) < max_ulong
equivalent to :
new_height * mem_space + new_height * new_height * raster * NUM_PDF14_BUFFERS < max_ulong
So it counts new_height quadratically, but it must be the linear multiple by the raster.
Debugged with the test case of the bug 689982.
It creates a 15Mb raster, but could not switch off the banding
even with -dMaxBitmap=1000000000 .

Fix (clist) : Skip writing unuseful data with linear color triangle.
DETAILS :
This fixes a minor problem what was discovered while working on
bug 689918 "Ghostscript 8.62 and 8.63 segmentation fault".
cmd_write_trapezoid_cmd wrote an unused data to clist when
processing a linear color triangle. The variables ybot, ytop are never used
while a clist interpretation. In same time the data are not initialized
in that case, so they imply an indeterministic content and length of the clist.

Fix (True Type font loader) : Can't work around unsorted 'loca' when 'loca' is not loaded.
DETAILS :
Bug 689893 "Regression: CID font emulation is broken."
A work around against unsorted 'loca' and its recent improvements
assume that 'loca' presents in sfnts. It is not true
when a CID font is emulated with a True Type disk font,
because in that case the font machinery delay loading
'loca' and 'glyp' elements until a real request from a document.
For more details see comments added in code.

Fix (PDF interpreter) : A temporary work around huge images with a soft mask.
DETAILS :
Bug 689080 "PDF Crash with Transparency at 2880 dpi".
This is a temporary workaraound for the problem,
see comment in code.
With this patch the test case doesn't crash,
but it needs -dBufferSpace=500000000 to complete in 15 minutes
on Core 2 Duo 2.4 MHz with debug build.
The test case is pretty big anyway - it generates a 4.2 gigapixel raster.
Thankls to Ray for obtaining the buffer space from a device.
I think the old code is incorrect because it looks applying the
mask two times : first when installing a mask buffer with
.begintransparencymaskimage in doimagesmask, and second time when
processing a Type 103 image in C code. The raster difference
is likely caused by that. I don't perform a deeper analyzis,
because it's a temporary fix which needs to be replaced soon.
All that is written in this paragraph are not sure,
because there is no time for a deeper analyzis before 8.63 release.
When we'll complete Type 103 images (with rasterizing after clist
and with a proper handling in pdfwrite), .begintransparencymaskimage
will likely go away.

Fix for Bug 689246. When performing interpolation, the interpolation is now performed in the source colorspace as opposed to the device space. Custom color callback is no longer bypassed by direct concretization as it was previously.
DETAILS:
Previous code would take device color 8 bit values and do the interpolation. That portion of the code is the same. For cases where we have nondevice color the handling is now different. Indexed colors are mapped to their base space and interpolated. This is followed by a remap operation. Device independent colors are interpolated followed by a remap operation.
Note that for cases where there is a significant enlargement occurring and we are not in a device color space, there can be a performance cost due to current inefficiencies in our color remapping operations. This can be costly if you have a CMYK CRD MLUT for example. There is currently a project underway to improve the efficiency of the color flow. For the current time, if this is an issue, improved speed can be achieved by invoking -dNOINTERPOLATION

Change the default GS_CLIENT_COLOR_MAX_COMPONENTS to 8 (down from 252).
This improves the performance for files with many images. This limits
the number of DeviceN components and the number of separations that
can be generated in the default build and causes 'limitcheck' errors
on CET tests that attempt to set a 250 component DeviceN space.
THIS IS NOT BACKWARDS COMPATIBLE, but the change in ths single file
so this can readily be rebuilt by customers that need more components
or anyone that demands conformance to this implementation dependent
result on the CET. Note that not all Adobe implementations support
250 components as CPSI does.
Currently only the tiffsep and psdcmyk devices can generate more than
8 separations, and then only when USE_COMPRESSED_ENCODING is used to
fit more than 8 components in a 64-bit color value.
This partly reverts rev 7159.

Fix (pdfwrite): limit checking of CIDfonts for 'fixed width' property.
Details:
Bug 689963 "Infinite loop converting PostScript to PDF"
In fact the loop is not infinite, but it does take a long time. When checking to see if a
font is non-proportional, ie all glyphs have the same width, and the font is a CIDFont, we
did not stop testing when the CID exceeded the maximum CID in the font instance. Instead
we continued to the full CID range (0xffffffff). Because the TrueType code returns a
default for missing glyphs if the font was truly non-proportional then it would take a
long time to search the entire range.
(zfcid1.c): In z11_enumerate_glyph, check the requested CID against the CIDCount for the
font. Return a rangecheck if we exceed it.
I believe only pdfwrite uses this code currently.

Fix (graphics) : Write tile id into a pattern clist.
DETAILS :
Bug 689818 "Regression: Test file imagemask-with-pattern.ps fails with banding and pbmraw ".
The old code doesn't write a tile id when writing the tile to clist,
because the clist interpreter doesn't use tile id.
This causes a failure after we implemented clist-based patterns.
While playing back a pattrn clist to a page clist writer device,
the clist writer does need a tile id
for choosing an entry of an internal hash table.
Actually the failure happens due to a strange check
"tile->id != gx_no_bitmap_id" in
clist_strip_tile_rectangle in gxclrect.c ln 479.
It is not clear what it was intended for.
When a tile id is zerfo, the check skips writing tile size to clist,
so that a zerodevide happens during the clist playback.
We decided to provide meanful ids
because the clist writer needs them anyway.
Fixing the check to be a subject of a separate patch
(if a fix is really necessary).
This patch simply writes tile id when the clist
is for a pattern. A new nacro IS_CLIST_FOR_PATTERN(cdev)
Defines the condition for that.
Some internal functions change prototypes
with adding a new boolean argument for_pattern to know
whether a clist is for a pattern.

Increase the default threshold for using the (much slower) pattern clist accumulator.
The 32Mb threshold is tolerable for most host systems and this can be modified during

Fix (pdfwrite): Images ina DeviceN space with more than 60 inks caused a crash.
Details:
Bug #689864 "Regression: 09-34.PS core dumps with pdfwrite"
When emitting an image, using the Flate encoder, the number of colorants in
the DeviceN space was not checked against the maximum permitted. Since the
encoder uses a fixed buffer whose size depends on the maximum number of inks, this
could cause a write beyond the end of the buffer.
(spngpx.h) Increase the maximum number of colorants to 256
(spngp.c) Return error if the number of colorants in the space
exceeds the maximum permitted.

Parse common color space keys in JPXDecode filtered images and pass them
to the filter, allowing JPX-encoded CMYK images to display properly.
Fixes bug 688807.
DETAILS:
The fundamental issue is that the jasper library does not support the
ISO 15444-2 (JPX) extensions to the JP2 format for handling full ICC
and CMYK color spaces. So while the the PDF image dictionary and the
JPX streams both specify a CMYK ICC profile describing the image, jasper
ignores the extended colr boxes and marks the image as sRGB + an unknown
component, just based on it having three or more components. Our stream
implementation used this information and tried to return RGB pixels when
the graphics library expected CMYK, causing errors or hangs.
Jasper should be amended to handle these extensions. However, since in
PDF a color space in the image's stream dictionary overrides what is in
the stream, I felt implementing the override was the more useful
resolution.
This patch doesn't handle all color spaces, just Device* and ICCBased,
which are the most common. In the case of ICCBased spaces, we try to
look up the alternate, and use that if it is a Device* space; otherwise
we guess based on the number of components.

Clean up the state machine in s_jpxd_process.
DETAILS:
The state machine didn't always respect the calling conventions for
filter process routines, and could return '0' (more input needed) when
'last' was true (no more input exists).
Also, the jas_stream member of the filter state isn't currently
necessary and has been moved to s_jpxd_decode_image(). Originally
it was envisioned that the jas_stream could seek on the filter's
source ghostscript stream and so would need a longer lifetime than
we're currently using. This has now been simplified to a local variable.

line.

Fix (clist writer) : Indeterminizm writing a degenerate curve.
DETAILS :
Bug 689911 Shifting raster data, Windows MSVC 8 non-debug build.
In function cmd_put_path the variable 'prev' was wrongly localized
in the loop body when need to save/pass data from the previous cycle.
It worked fine with debug build, because the compiler
always commits variables to RAM for debug purpose.
With release build the variable 'prev' never changes
because formally speaking the program never uses its value
after it is initialized.
The bug persists since the repository was created on March 9 2000.
The old behavior may be indeterministic.
With MSVC8 the effect is occasionaly visible when a degenerate curve
{x y x y x y x y} is written into clist.

Fix (graphics) : Clean image enumerator before releasing it.
DETAILS :
Bug 688845 "Segmentation Fault on EPS 2 PDF conversion", comment #38.
Adobe Illustrator creates a Postscript document,
in which an image data procedure executes 'save',
and the corresponding 'restore' appears after the image end.
DCue to that the image enumerator is freed at a higher save level than
it was allocated, so that gs_free_object works idle.
Nevertheless pointers must not in the structure,
because they may point to blocks already released
by the client's subclass method for end_image.
Leaving them uncleaned caused a real crash in the garbager - see bug 688845.
The patch defines the new function gs_image_free_enum,
which is intendend for a safe releasing of an image enumerator
from Postscript interpreter.
It cleans the entire subclassed enumerator,
including all possible pointers created by subclasses.
All end_image implementations,
which may be called from Postscript interpreter,
must call this function for releasing image enumerators.
The 'memory' pointer moved from subclasses to gx_image_enum_common.
We believe that in the old code all subclasses define and initialize it.
Working on this patch we suspected memory leaks
from image enumerators with some devices.
Particularly we suspect that subclasses if gx_device_vector
(pdfwrite, ps2write, etc.) never release image enumerators (not sure).
This patch does not do any attempt to re[pair such leaks,
because we want the new code doesn't
change the behavour too much in order to simplify the testing.
A work on leaks to be done separately.

Fix (stroking) : Prevent unpainted gaps between neighbour strokes that could appear due to stroke adjustment.
DETAILS :
Bug 687974 "pdf file has banding with ghostscript but not with acrobat".
The test case includes a gradient, which is represented
as a set of paralel strokes. Due to stroke widths equals to fractional pixels,
stroke adjustment shifts some of them so that
an unpainted gap appears between strokes and the gradient looks striped.
Note the test document is created with Quark Express 4.11 .
This patch implements a hewristic recognizer for parallel contacting strokes
and suppresses stroke adjustment for them. See comments in code
for more details.
Note that the recognizer data are associated with a device but they
are not a device property. We store them in a device structure because
we haven't got an associated structure in the graphic state,
and we don't want to introduce one now against extra complexity
with memory management. Also the recognizer code
Appears to be distributed along multiple functions and we would like
to apply a better incapsulation. Nevertheless the encapsulation
would cause CPU time expense for multiple small function calls
unless we create new macros. So commonly we're unhappy of
this code but we don't see a better solution.
Also note that the recognizer data is copied from/to clipper
device when the stroking algorithm installs and deinstalls a clipper.
So the data actually is not a property of a device.
Also they're not a part of graphic state because they must live
across gsave/grestore (the test case requires so).

Fix (True Type font loader) : Work around incorrect numGlyphs.
DETAILS :
Bug 689516 "problem reading PDF: Failed to interpret TT instructions (ref 7814)".
The bug report supplies a PDF document, which embeds a TT font
with a too small numGlyphs. The loca table contains more glyphs and
they are referenced in a text. The font is incorrect, but Acrobat handles the document.
This patch checks whether there are glyphs behind numGlyphs and
extends numGlyphs to cover them. Also improved error handling in ttfmain.c .
Besides that, now we print a warning about an incorrect numGlyphs
in release build. The olkd code did with debug buil only.
I believe that users need to know whether a font is broken, and that
its rendering is hewristic.

Enhancement (graphics) : Delay applying type 1 raster patterns until clist interpretation (continued 4).
DETAILS :
The old code assumes that a pattern always fits into the clist writer buffer.
However ppmraw -r400 176-01.ps violates this assumption.
This patch implements a subdivision of a pattern into slices,
each of which is smaller than the buffer size.
1. The new function cmd_get_buffer_space retrives maximal available space
in the clist writer buffer (gxclutil.c).
2. cmd_put_drawing_color now implements a cycle for slicing big patterns.
Each slice writes to clist as a separate clist instruction (gxclpath.c).
3. gx_dc_pattern_write_raster drops the constraint that the pattern
fits into a single buffer (gsptype1.c).
4. The clist interpreter is enhanced with composing a pattern from slices
(gxclrast.c).

This was a simple fix which puts the callback structure address into gslib_ctx instead of in the graphic state. This fixes the customer's issue. The postscript interface for custom color remains as it was with this commit. Soon, in the future, we will be changing to a C API interface. There does remain an issue with respect to object type tagging. If high level images occur with banding, the object type is different than if there was no banding.

Rename the cairo device parameter CairoSurface to CairoOption.
Better handling of libcairo errors.
Add (untested) support for passing a libcairo context pointer
through the CairoContext device parameter for rendering to a
client drawable.
Details:
CairoSurface was renamed with the expectation that it will in
the future take additional options that might not be surface
specific. Also, the CairoSurface name was chosen with the idea
that a client could pass a pointer to an already allocated
cairo_surface_t, but it's just as easy to pass the result
of calling cairo_create() on such a surface as a context
pointer. Therefore we've added CairoContext and renamed the
old CairoSurface parameter to CairoOptions.
The new command line would be:
gs -sDEVICE=cairo -sCairoOptions=ps -o - test.ps
to set the output format to ps.

New 'cairo' output device using the libcairo graphics library.
Patch by Behdad Esfahbod.
Details:
This output device uses the LGPL cairo library to create file output in
a variety of formats. Currently supported are png, svg, pdf, ps, eps.
The output format can be specified with the CairoSurface device
parameter. If this parameter isn't set, the device will guess
based on the filename extension given in OutputFile. Thus, these
two command lines are equivalent:
gs -sDEVICE=cairo -sCairoSurface=svg -o tiger.svg examples/tiger.eps
gs -sDEVICE=cairo -o tiger.svg examples/tiger.eps
Other output formats are selected like so:
gs -sDEVICE=cairo -o tiger.png examples/tiger.eps
gs -sDEVICE=cairo -o tiger.pdf examples/tiger.eps
gs -sDEVICE=cairo -o tiger.ps examples/tiger.eps
Only vector drawing is implemented at this point; images and text are
handled by fallback and will not give compact results. The resolution
for rasterization is set by the -r parameter as usual.

Previous to this revision the pxlcolor and pxlmono devices would revert
to using gx_default_begin_image() when bits_per_pixel==24, resulting
in very large images. Now the image data is written directly into the

the lum_*_weight values from gxlum.h.

This is the "final" merge of the mtrender (multi-threaded clist rendering)
branch into the trunk. The default behavior is still the same, i.e., the
clist rendering is done in the same thread as the parsing (main thread).
The 'gsmalloc' memory allocator now ALWAYS uses a mutex to lock accesses
in case it is used by a multi-threaded client. This was determined to
result is less than 1% performance hit on a single threaded client.
Refer to the log messages on the mtrender branch for details on the
design of the multi-threaded clist rendering, but the summary is that
-dNumRenderingThreads=# (default 0) determines the number of background
threads REQUESTED for rendering bands. If the platform doesn't support
threads, or if there is an error starting the threads from the clist_
get_bits_rectangle_mt hook, single threaded rendering will be used.
The number of threads may be less than the requested number if the
number of bands is less than the request, or if there is an error
setting up threads (as many as can be created, up to the request will
be used). The -Z: debug switch emits status messages indicating how
many threads are requested (-dNumRenderingThreads) and the number that
is actually used.
Many files show little if any improvement with multi-threaded clist
rendering since they are dominated by the clist writing time, or by
the time required to write the output. No files seen to date show a
performance hit greater than aobut 3%. Setting NumRenderingThreads
to a count higher than the number of CPU cores available does not
seem to help or hurt much, but there is overhead (per page) with
starting threads and allocating band buffers, so a very large count
is not productive.
The best performance seen on an Intel Core 2 Duo system, on a
particular file is about a 75% performance improvement (completing
the page in 57% of the single threaded time). This time did not
include writing a file (output to /dev/null).
In order to prevent memory mutex (locking) contention from slowing
down multi-threaded clist rendering, each thread uses a 'chunk'
wrapper on NON-GC the non-gc memory allocator. Each chunk allocator
is thread-safe/instantiated, so the locking only occurs on chunk
allocations to the wrapped (target) memory allocator.
The 'BAND_LIST_STORAGE=mmeory' option has been supplemented to allow
multiple concurrent threads to read the clist 'memfile'.
The "autoconf" files (configure.ac and Makefile.in) have been improved
to hook the 'posix' pthreads if available, so linux and Mac OS/X will
be able to support the multi-threaded clist rendering.

Use 'realtime' instead of 'usertime' for -Z: timing information. On some
systems (Windows) these are equivalent, but on linux, 'usertime' is the
time for the current thread which interferes with timing collection on
different threads (multi-threaded rendering did not include any time for
the threads). INCOMPATIBLE CHANGE, but this is only debug info.
[src/imain.c]
2008-05-08T21:28:30.163536Z Ray Johnston
Allow some compile time constants that affect performance to be set as
/D compiler flags (via XCFLAGS makefile macro).
MAX_BITMAP_PATTERN_SIZE controls when the clist pattern accumulator is used,
and on machines with a decent amount of RAM, the default of 1 Mb is too
small and causes the slower clist method to be used too often. Setting this
to 32 Mb is probably better on hosts.
The GS_CLIENT_COLOR_MAX_COMPONENTS default of 252 is needed for Adobe CPSI
compatibility and for RIPS that want to use a large number of DeviceN
colorants, but this increases the size of some allocations and slows down
performance and is much too large for printers. Setting this to 6 or 8 is
probably plenty.

Add support for recursive mutex on posix. Multiple threads that perform
'locking' before calling an object's finalize need this to prevent
deadlock if the finalize calls 'free'. This protection is standard on
Windows, but PTHREAD_MUTEX_RECURSIVE attribute is not available on
many systems.
The method, using pthread_self and pthread_equal, was extracted from
a web information page and tested on linux.
NB: The multi-threaded clist rendering no longer needs this since
the 'chunk' memory wrapper calls the 'finalize' function without
locking, so the deadlock no longer occurs.

Fix memory leak observed with DEBUG=1 build on mtrender branch. The
'levels' and 'bit_data' of halftones were being leaked when halftones
were set by the clist reader.
DETAILS:
Since the 'dht.rc' was filled with 0's, the rc.memory would cause the
gx_imager_dev_ht_install to copy the order (mem_diff would be true).
The gx_ht_copy_ht_order would make a copy, but the one passed in
was never freed. Since the 'src' component information was cleared
during the install, gx_ht_read_and_install needs to save a copy of
the components so that the orders can be released.

Fix (graphics) : Wrong pattern phase when pattern applies to a band with non-zero origin.
DETAILS :
The old code computes pattern phase modulo rep_width, rep_height.
It appears wrong when pattern step is much bigger than the pattern bbox.
Really the bbox determines the painting area as rep_width, rep_height,
but the phase to be computed modulo pattern step.
Besides that, the old code aplies a wrong sign, which is oposite to a band offset.
This bug has no effect with Postscript interpreter, because
currently patterns never apply after banding,
but it will change with the next patch.
With no banding the phase is always zero.
Other interpreters may need additional improvements
(we suspect they are bug-to-bug compatible).

Fix (graphics) : Convert imagemask into a clipping path when painting a big pattern.
DETAILS :
Bug 689440 "PostScript file generates infinitely large temp file".
In the past we implemented a conversion of imagemask intoi a clipping path
for a faster painting a shading color. Now we do same for big type 1 patterns.
1. Enhanced the condition in gximask.c for passing big patterns.
2. In gximask.c filter out degenerate rectangles,
which can't be painted with gx_device_color_fill_rectangle.
3. Set a pure black color in gsimage.c,
because patterns can't convert with gx_device_black.
4. In gxacpath.c added the default copy_mono method
to the clip list accumulator device in order to handle
imagemask with the pure color set by (3).
5. In gximask.c added a proper setup of device width and height
to clip list accummulator, because gx_default_copy_mono needs them.
6. In gximask.c gx_device_retain is now called on errors.
The old code does not call it, and we think it caused memory leaks
in some rare cases.
This patch changes the behavior with shadings, because the old code paints
imagemask with the shading color to clip list accummulator.
The new code does with pure black, so that now the clipping is not
restricted with the shading area or the shading BBox.
But we believe that the final result should be same
and the performance should be some faster.
Note we keep the call to gx_dc_pattern2_clip_with_bbox_simple
in gx_image_fill_masked_end rather now it is always idle.
Doing so for the case if this change will need undoing for shadings.
The new code doesn't use the writing of big patterns into clist,
which was done with recent revision 8655.
That change appears unneccessary for this particular bug.
However we want to keep it in HEAD branch because it may be useful
for further impeovements when imagemask produces a too big clipping list.
This patch causes a minor raster difference with Bug688396.pdf .
Delaying it for better times.

Enhancement (graphics) : Delay applying big patterns until page clist interpretation.
DETAILS :
This is a preparation for fixing
the bug 689440 "PostScript file generates infinitely large temp file".
The old code decomposes the imagemask into rectangles,
each of which decomposed the pattern color into a huge list of rectangles.
See more about the old code in Comment #11 of the bug 689440.
Now we delay the decomposition until the page clist playback.
This patch reduces the clist file size for the bug 689440
from 355GB to an acceptable size of 316Mb. A further shortening
is possible as explained in (5) below. But the rasterization time is still
unacceptably long - more than 48 hours. It will be improved
in a next step with converting imagemask with pattern color
into a painting of a pattern color with a mask clip device.
1. The old functions gx_dc_pattern_write, gx_dc_pattern_read actually
are generic functions for multiple color types,
which simply return an error. Renamed them into
gx_dc_cannot_write, gx_dc_cannot_read.
2. Implemented new gx_dc_pattern_write, gx_dc_pattern_read for clist-based patterns.
They copy pattern clist data to/from page clist. Currently this code
doesn't try to compress the data, but probably we'll need to do that.
3. Changed a condition in gxclimag.c to pass imagemask
with a clist-based pattern color to clist writer.
Also moved some checks to provide image matrix to be computed
when the new condition is true.
4. Added more functions into gxclist.c, gxclist.h for accessing
data of a clist-based pattern.
5. gx_dc_pattern_read now constructs pattern cache and stores the
clist-based pattern "tile" to it. The clist reader releases the cache before exiting a band.
We will need an optimization agains redundant writing of patterns into page clist.
This necessary optimization to be done in a next step.
6. Propagated error codes in gxclread.c, gdevfax.c for easier debugging.
7. Improved debug printing in gxp1fill.c to designate
recursive calls to clist interpreter when a clist-based pattern
in interpreted while a page clist playback.
8. Added new accessors into gxpcmap.c, which are needed
to access pattern cache while a page clist interpretation.
9. Updated dependencies in makefiles.
10. Fixed the dependenco of gxdcolor.c on gxdevcli_h, which was missed before this change.
11. Added the pattern color type into the list in gxdcolor.c,
because now we need to write it into clist. An old comment
reads that it was not included against unuseful reference to
pattern stuff in a Postscript Language Level 1 build.
The reference now appears, and this is unfortunate.
We think that level 1 builds are not important in nowadays.
On necessity it may be improved in a separate change.

Implement loading of OpenType CFF font as a CIDFont resource in PDF reader.
Bug 689763, customers 531, 850.
DETAILS:
PDF can use OpenType font with ordinary CFF data as a CIDFont. Such a font is
referenced by /CIDFontType2 and may have /CIDToGIDMap table. The following
changes have been done to support this usage.
- A flag that forces CIDFont generation was added to CFF font loader.
- When the flag is on, CFF font is converted to a Type 9 CIDFont.
- The FontSet resource is returned by the value from the font loader
because it can be of either Font or CIDFont type,
- Since CIDMap has no effect on CIDFont Type 9, CIDToGIDMap is interpreted
by PDF reader to modify GlyphDirectory to the same effect.
- Unused CIDMap is no longer generated for CIDFontType2 objects that are not
TrueType CIDFont resources.

Enhancement (graphics) : Generalize prototypes of color serialization methods for big color data.
DETAILS :
This is a preparation for fixing
the bug 689440 "PostScript file generates infinitely large temp file".
The old serialization methods assume that color data can fit into a small buffer.
Now we want to drop this constraint to allow to write big patterns into clist.
See comment in code for details.
This change is algorithmically equivalent.
This patch adds a new argument to color serialization methods.
For a while the new actual parameter is always 0,
and the (untrivial) methods check for it.

Fix (PDF interpreter): Optionally omit rendering of /.notdef glyphs
from TrueType fonts.
Details:
Bug #689757 "Extra square characters rendering PDF file".
When rendering glyphs in a TrueType font, and the glyph is not present
in the font, GS (correctly) draws the /.notdef glyph (or glyph ID 0)
instead. Under some conditions, however, Acrobat does not do so, but
does leave a 'gap' apparently corresponding to the width of the
original glyph (if a /Widths array is present), or the width of the
/.notdef glyph.
Exactly what causes Acrobat to do this is unclear. In the thread for
bug 687929 it was suggested that Acrobat was substituting a standard
font with a /.notdef defined as an empty glyph. However changing the
font name had no effect.
Using a pdfwrite-produced PDF file, if I remove the symbolic flag
from the font, and any direct reference to /.notdef in the Encoding
/Differences array, then Acrobat does not display the /.notdef
glyph. However, starting with a Distiller-produced PDF file, and
either altering the font to symbolic, or adding a direct /.notdef
to the Encoding, or both, makes no difference, Acrobat still does
not render the /.notdef glyph.
The behaviour of Acrobat is probably technically incorrect, but
we need to attempt to render files similarly, if at all possible.
However, since the appearance of a /.notdef is usually indicative
of an error, this has been made optional.
We can't substitute a space glyph for the /.notdef as has been
suggested, because we can't guarantee the existence of a space glyph
(eg Arabic, which has no space) and can't guarantee that the space
makes no marks even if present.
However, we still want to apply the Width of the glyph, so that
spacing works out correctly, if we simply skip the /.notdef glyph
then words may collide, as in the case of the file for this bug.
This means we must run the glyph through the text routines, as the
width is applied there.
A new user parameter '/RenderTTNotdef' controls whether glyphs
named /.notdef in a TrueType font should be rendered or not. This
is also controlled by a systemdict parameter /RENDERTTNOTDEF. The
PDF interpreter will set the user parameter to the same value as
the systemdict parameter, allowing this to be controlled from the
GS command line.
The user parameter defaults to 'true' which renders TrueType /.notdef
glyphs (so that these are properly rendered in PostScript), the
RENDERTTNOTDEF systemdict parameter defaults to 'false', which is
used by the PDF interpreter to set the user parameter, and therefore
disables rendering of TT /.notdef glyphs in PDF files.

Fix (pdfwrite): Incorrect cmap aubtables written for 'non-symbolic' TrueType
fonts, when PDF/A output is enabled.
Details:
Bug #689754 "Substituting .notdef for "german umlauts" when generating PDFA".
Normally when writing TrueType fonts GS emits 'symbolic' TrueType fonts, and
correctly outputs both a 1,0 and 3,0 cmap subtable (with appropriate character
offsets, see section 5.5.5 of recent PDF specs).
However, when PDF/A output is enabled, and the TT font to be output only
contains glyphs from the Adobe Latin set, and these are ordered in
accordance with that set, then we emit a 'non-symbolic' TT font. (For PDF/A
we do not emit 'symbolic' fonts, if the font is not 'non-symbolic' then we
write a CIDFont instead.)
However, when writing the non-symbolic font, we continued to write the same
cmap subtables. Acrobat does not use the 3,0 subtable with non-symbolic fonts,
and falls back to the Mac Roman (1,0) subtable instead. For many glyphs this
works correctly, but if the font is WinAnsi compliant, and the glyph is one
of those for which the character position differs between Mac and Windows,
then the glyph cannot be found by Acrobat.
By writing a 3,1 (Windows Unicode) cmap subtable we can ensure this does not
happen, as Acrobat will use this in preference to the 1,0 subtable.
(gdevpsf.h) Add a new TrueType writing control flag WRITE_TRUETYPE_UNICODE_CMAP
This is used to control whether we write a 3,0 or 3,1 cmap subtable.
(gdevpdtb.c) When setting options for TrueType font writing, if we are
writing PDF/A, then set the new flag so we get a 3,1 Unicode subtable.
(gdevpsft.c) Create new boilerplate for a type 6 Mac Roman subtable,
followed by a type 4 Windows Unicode subtable. Create a new routine
'write_unicode_cmap_6' which uses the new boilerplate to write this
kind of subtable. In write_cmap, check if we have been asked to write a
Unicode cmap subtable, and use the new routine if so. Do not bias the
character codes if writing a Unicode table.

Fix (pdfwrite): pdfwrite embedded TrueType/Type 42 fonts which
specifically forbid embedding.
Details:
Bug #689693 "GS embeds licensed fonts when generating PDF".
For Type 42 fonts, in order to prevent embedding fonts with license
restrictions we need to retrieve and honour the /FSType key if present
in the FontInfo dictionary of the font.
We also need to check the embedding status of TrueType fonts read from disk
in a similar fashion to Type 42 fonts downloaded in the course of the job.
Finally, when writing a TrueType font to a PDF file, we need to preserve any
existing embedding rights by setting fstype appropriately in the OS/2 table.
It is possible to permit font embedding even when the embedding rights
are non zero and we should preserve these.
(gxfont.h) Add a new parameter, EmbeddingRights, and a new flag
FONT_INFO_EMBEDDING_RIGHTS, to the gs_font_info structure.
(zfont.c) In zfont_info, if we request the EmbeddingRights, and the font has
a FontInfo dictionary, retrieve the FSType if present.
(gdevdtf.c) When determining whether a font may be embedded, retrieve the
font info, check the 'members' structure member after retrieving font info
to see if the EmbeddingRights member has been updated. Assume embedding
allowed if the member has not been updated.
(gxfont42.h) Add a new member os2_offset to the gs_type42_data structure, to allow
us to read from the OS/2 table later.
(gstype42.c) In gs_type42_font_init, when reading the TrueType Table directory, store
the offset to the OS/2 table.
In gs_truetype_font_info, if the caller has requested the embedding rights
and they haven't already been retrieved from an FSType entry in the
FontInfo dictionary, get the OS/2 table and pull the fstype value from there.
(gdevpsft.c) When writing a TrueType font, and we don't have an OS/2 table to
copy (appears to always be the case), check to see if we have any
embedding rights information in the original font, and preserve it if so
by setting the fstype entry in the OS/2 table.

Fix (transparency) : Transparency compositor device recreation was incorrect.
DETAILS :
This problem was apparently detected when working on another problem.
The pdf14_recreate_clist_device code was wrong.
Regularly we never call that function, because
PDF interpreter creates the transparency compositor device once per page.
Nevertheless we store the right code since it is debugged.

Fix (bbox device) : box_fill_path needs as path for shfill.
DETAILS :
Since revision 8017 the function gs_shfill includes a branch for
a faster handling of the Postscript operator shfill,
which does not provide a path to fill. It uses the clipping path instead.
The bbox device appears to be incompatible with that optimization.
This patch adds a special branch to bbox device to handle a shading fill
with no path.
Please note that since revision 8017 the call
dev_proc(dev, pattern_manage)(dev, gs_no_id, NULL, pattern_manage__shfill_doesnt_need_path)
must return a proper information about the device's fill_path method.
In most case it is doe with the default implementation gx_default_pattern_manage,
but the bbox device ises gx_forward_pattern_manage instead,
which appears wrong for bbox_fill_path. We decided to add an optomized branch
rather than apply the slow general method.

Fix (clist) : Some transparency compositor commands don't need CTM.
DETAILS :
The old code writes CTM with each transparency compositor command.
Actually it is only needed with begin_transparency_grup and
begin_transparency_mask. So we can skip CTM with
when writing other commands to shorten the clist file.
Note clist reader now sets zero CTM when reading transparency
compositor command with no CTM. We believe it is useful because
subsequent graphics objects need to restore CTM of a containing group.

Fix (clist) : Crop transparencsy commands while clist writing, step 3.
DETAILS :
This really crops transparency compositor commands with bands
that are covered by the transparency bbox.
Actually the statement above has one exception. When a transparency bbox
covers more that 2/3 of all bands, we still write the commands to
the "all bands" list for a shorter clist file. We noticed that
the clist playback time strongly depends on the file size.
1. The new method gs_composite_type_procs_t::get_cropping
replies what bands are covered by the compositor.
When it gives a non-trivial result, clist_create_compositor
writes the compositor command to those bands,
which are covered with the cropping (Exception :
if too many bands are covered, it writes the command to
the "for all bands" list).
2. Since some bands skip some compositor commands,
while clist reading the association of masks to groups
becomes more complex. Before this patch each group
was associates with the mask, which was created immediately
before it at same transparency stack level.
After this patch some groups may be skipped, so that
clist reader may recieve extra masks, because masks are
still use the container's group bbox. For skipping such extra masks
we provide a numeric identifier of a mask, which is named mask_id.
Here is how it works :
2.1. All masks recieve serial numbers (mask_id) while clist writing.
2.2. Each mask command is written with its mask_id.
2.3. Each group command is writen with mask_id,
which belongs to the mask that is assocuated with the group.
2.4. While clist playback pdf14_pop_transparency_group checks whether
the mask amd the group have same mask_id. If not, the mask is extra
and it must be droped.
2.5. Note the old assiciation logic is still working,
and it may skip some masks as well.
2.6. If the rasterization happens with no clist, mask_id is always zero.
In this case the old logics is only working.
Maybe we'll provide non-zero values someday.
2.7. See comments in code for more details.
3. The method gs_composite_type_procs_t::clist_compositor_write_update
is now some generalized. Before this patch it only updates the clist writer state
with the compositor features. With this patch it also adds
some information from the clist writer state to the compositor parameters.
Particularly it provides mask_id to the compositor command.
Thus now it updates *both* clist writer and the compositor parameters
to comply each another. For a while, in order to simplify the patch,
the compositor argument is still 'const'. Will need to fix someday.
4. Now we need to save mask_id in a stack that reflects the
transparency nesting. The cropping stack, which was introduced
in the last patch, now works for that. To provide that
we add mask_id to clist_writer_cropping_buffer_s,
and use clist_writer_push_no_cropping to save amsk_id
over inner groups.
5. state_update(ctm) in c_pdf14trans_clist_write_update is replaced
with code, which updates CTM from the transparency compositor command.
The old code is not fully correct, because it takes CTM from the imager state,
rather we havn't got prcatical cases when it gives a wrong result.
6. drop_compositor_queue now calls adjust_ctm for compositors being dropped.
The old code is incorrect because it can miss a CTM update when
a compositor sets some CTM and later a non-compositor object
sets same CTM. In this case the clist writer skips the second CTM on writing,
and skipping the first in the clist reader will miss the CTM completely.
We haven't got practical cases for that.
7. Improved some debug printing.

Fix (clist) : Crop transparencsy commands while clist writing, step 1.
DETAILS :
This is a preparation to the next step.
In general, the behavior doesn't change,
but implementation details differ.
The old code maitains a flag cropping_by_y in the clist writer,
which triggers a cropping of objects by the Y axis.
The old code isn't perfect, because
it first crops by [cdev->cropping_min, cdev->cropping_max],
and then by [0, cdev->height].
In the new code we unite both croppings into a single one.
For doing that we remove the flag, and provide
the right interval [cdev->cropping_min, cdev->cropping_max]
in any case. Initially it is [0, cdev->height},
and it is narrowed when a shading bbox is set.
To restore the initial cropping after the shading
is complete, we maintain 2 new fields
save_croping_min and save_cropping_max.
So now the cropping mechanizm does not depend
on shading, and clients may set a croping when they need.
We'll use this feature in the next patch.

Fix for compression always falling back to no compression in
pclxl_write_image_data(), bug 689732.
Details:
After much tracing of srle.c and gdevpx.c I believe this bug is in
the portion of s_RLE_process() that looks ahead in order to be able
to optimally compress the data. Rather than attempting to modify the
function and probably breaking something else I'm taking the 99% solution
and just calling s_RLE_process with last set to true instead of false.
This disables the look ahead feature, presumably making the compression
very slightly suboptimal but at least now it works.
This change results in pxl files that are significantly smaller than
before (i.e. the test file associated with bug 689595 is reduced in size
from 1.1 megs to 387k).

Fix (pdfwrite): problems with type 3 fonts executing 'show'.
Details:
Bug #689685 "OpenType font incorrectly converted to PDF".
The File is from Quark XPress and contains a type 3 font which
executes a 'show' and a 'charpath stroke' with a glyph from a type
1 font. Further, it executes a 'charpath' on this type 3 glyph.
Pdfwrite was unaware, when processing the 'show' that this was
inside a charpath operation, and emitted the shown glyph.
Modified pdfwrtite to be aware that a charpath is in operation, and
to have the graphics library handle any show operations.
(gdevpdfx.h) Add a new flag 'type3charpath' to the gx_device_pdf
structure.
(gdevpdfb.h) Add an initialiser for the type3charpath flag (also for
the last_charpath_op which was missed in that change)
(gdevpdtt.c) In gdev_pdf_text_begin, if type3charpath is true, go
straight to the default text processing. Otherwise, check to see
if this is a type 3 font, and the operation is 'charpath'. If so
then create a pdfwrite text enumerator to process the text.
In pdf_text_process, if we have a type 3 font, the operation is charpath
and type3charpath is false, set it to true and go straight to the
default text handler. When the enumerator is completed, if type3charpath
is true, set it to false.
In pdf_text_process, while handling text, do not start accumulating a
charparoc if type3charpath is set.
Finally, in pdf_text_set_cache, if type3charpath is set, simply execute
the standard cache routine.

Fix (pdfwrite): problems with type 3 fonts executing 'show'.
Details:
Bug #689687 "Regression: pdfwrite DEVICE produces bad text".
The File is from Quark XPress and contains a type 3 font which
executes a 'show' and a 'charpath stroke' with a glyph from a type
1 font.
The code for revision 8265 converts these into a '2 Tr' in the
PDF file. However, I missed the case of this occuring inside a font,
resulting in much too large a strokewidth being set. This code takes
account of the font matrix.
NB there is still a potential problem. There is no way currently to tell
the difference between a charproc which explicitly sets a stroke width
and one which inherits it from the prevailing graphics state. Currently
we will write a font which always emits the stroke width at the time
the font was first used. There is no simple way to address this, we
could set the stroke width to an invalid value during the course of a type
3 glyph, and check it before emitting the stroke, but this is dangerous.
However, this seems unlikely to be a real problem in practice, since altering
the stroke width outside the font might result in unpredictable widths
dependent on the point size. I have chosen not to open a bug for the
possible condition at this time.
(gdevpdfd.c) gdev_pdf_stroke_path, if we are converting to a PDF text
rendering mode, and are inside a type 3 font glyph description, take the
font matrix into account when calculating the strokewidth.

Bump the revision after the 8.62 release.
[doc/News.htm lib/gs_init.ps src/gscdef.c src/version.mak]
Version 8.62 (2008-02-29)
This version is the next in our line of scheduled semi-annual releases.
There were approximately 55 bugs fixed since version 8.61. Some fixes
and improvements of note were:
COMPILE_INITS=1 was broken in 8.61 and now works as expected.
Fonts are now distributed in the Resource/Font directory and will be
included in the executable if COMPILE_INITS=1
The tiffsep device was fixed for using more than 8 colorants.
Shadings, overprinting and transparency were optimized and are substantially
faster than in 8.61, particularly for large format or high resolution
rendering when using the 'clist' banding mode.
Changes were made to prevent near unbounded growth in memory usage and
corresponding performance problems on a few test cases.
The 'pdfwrite' device was improved to fix some compatibility issues with
PDF/A and to improve some font embedding and other issues.
The 'ht_ccsto.ps' Stochastic Threshold array was completely changed to
be more useful. The values in the threshold array were inverted, so
the number of 'light' colors was limited and using it generally caused
prints that were too dark.
The 'runpdfbegin', 'dopdfpages' and 'runpdfend' PostScript pseudo-operators
that were inadvertently removed in 8.61 were restored. This also restored
the functionality of toolbin/pdf_info.ps to display PDF creator stats,
fonts used and page sizes.
The halftone tile cache sizes and cache effectiveness were improved to
help the performance when tiling with large cells or threshold arrays.
The following bugs were
open at the time of release:

Incompatible changes
Not strictly a compatibility issue, but the default URW (GPL) fonts are now
distributed in the Resource/Font/ path which can increase the number of
file handles open for PostScript that opens all of the resources. Also
the size of the %rom% rom file system within the executable when using
COMPILE_INITS=1 is larger by the amount needed for the fonts.
Also not strictly incompatible, but some alternate fixed-point code
was stripped out, so FPU_TYPE and other FPU related makefile macros
are gone or don't cause any difference in the code generated. Also the
'USE_ASM' macro was removed, since we expect modern compilers to do
sufficient optimization.
Some old (deprecated) "helper" scripts were removed: gsindent, gssubst,
many2pdf.tcl, and pre.
The unused 'cmap' (special color mapping) and 'ropc' devices were
removed from the distribution.
The 'ht_ccsto.ps' Stochastic Threshold array was completely changed to
be more useful. The values in the threshold array were inverted, so
the number of 'light' colors was limited and using it generally caused
prints that were too dark. This is an improvement, but incompatible

Fix COMPILE_INITS=1. Note the next commit to the PCL tree will combine
with this one, but we can't commit to both trees atomically.
DETAILS:
Tested with Windows and linux. Needs OS/2 testing. Other build systems
may have bit rotted, and I don't hav them to test. Some of the changes
here are to allow working with a PCL or XPS only build where the PS
interpreter is not used/needed.
I noticed that the default systemparam value for FontResourceDir isn't
getting et to %rom$Resource/Font/ as it should, but GenericResourceDir
_is_ being initialized correctly to %rom%Resource/ which is _NOT_
fixed by this commit.

Ghostscript Bug 687345 "Image interpolation problem at a band boundary"
Ghostscript Bug 689718 "Regression: differences in FIG3.eps".
1. siscale.c : The revision 8529 patch part 4 tried to represent 'ceil' with rational
arithmetics. But when downsampling the argument still uses a floating
number WidthIn, so we still need 'ceil'.
This patch converts the formula back to floats,
assuming that double precision is enough for precise result
because source image size usually is smaller than 2^24.
The wrong rational representation of 'ceil' caused an array element index
to fall outside the array. Debugged with FIG3.eps.
2. Improved debug printing and visual trace.

DETAILS :
Ghostscript Bug 687345 "Image interpolation problem at a band boundary"
This is a further improvement to image placement precision.
Debugged with a.pdf .
The old code provides insufficientg precision when computing
transformation matrix for an image. This computation
include matrix inversion and matrix miltiplication.
The old code uses floats and causes a visible shift of subimages with banding.
The new code uses double precision.
We didn't test how it relates to the revision 7026 change,
which dectreased the matrix precision for CPSI compatibility.
It should be a separate job.
In the new gsmatrix.c code we simply duplicate old code fragments
and replace types for double. We don't want to define a template
for now. Will see after the code passes enough practical work.
Besides that, in gxidata.c replaced fixed2int_pixround
with fixed2int_pixround_perfect. It is not related to a.pdf,
but we believe it is an useful change.
In gxipixel.c the patch replaces dda_advance with a repeated dda_next.
The old code appears implrecise due to loosing fraction pixels.
It eliminates a 1 pixel difference with Bug688789.pdf .

Fix (images) : Improve coordinate precision when scaling an image (continued 3).
DETAILS :
Ghostscript Bug 687345 "Image interpolation problem at a band boundary"
1. The macro fixed2int_pixround returns a mathematically incorrect
result with negative half-integer arguments.
For example fixed2int_pixround(-2.5) = -3 when the math gives -2.
We guess it was designed for positive page coordinates only,
but later it was applied to objects with negative coordinates.
Particularly, an image can start outside the page with a negative coordinate,
and fixed2int_pixround causes distorsions with banding.
We do not update fixed2int_pixround for backward compatibility
of other parts of the algorithm. Instead that the patch defines
a mew macro fixed2int_pixround_perfect, and applies it to
images with Interpolate=true. (gxfixed.h, gxipixel.c, gxiscale.c).
2. Added gx_image_enum_s::yi0 to provide entire image origion in the page.
This value does not depend on band size, so it gives more stability -
see below. (gximage.h).
3. Added entire image sizes to stream_image_scale_params_s
for source image and scaled image. These values do not depend on band size
and provide more stability - see how they are used in siscale.c.
(sisparam.h, gxiscale.c).
4. (siscale.c) calculate_contrib now computes the filter kernel center
with global (page) coordinates of the image, using the right macro
fixed2int_pixround_perfect and with the rational arithmetics
instead floats. It gives the kernel center position relatively to source image
with no dependence on the band size. Also improved the debug printing
about that.
5. In siscale.c we keep track of some experiments done while
developing the patch. We need to save them to history because they're not trivial.
See comments in code. We'll remove them from trunk with a separate patch.

This patch does not change the algorithm,

Improve Halftone tile cache efficiency. Make default cache large enough
on default 32-bit (LARGE) configuration to allow for > 256 cache tiles
when using the 'ht_ccsto.ps' 167x167 Threshold array. Change cache
lookup logic to eliminate collisions when the number of cache slots
exceeds the number of levels (the normal case). Remove duplicated
ht cache default size #defines and normalize the names to end in
_size (to imply size in bytes) and be consistent with other similar
function/macro names.
DETAILS:
When we have more cache slots than the number of levels, we can use
the 'b_level' directly and don't lookup based on the 'number of bits'
(level). This ELIMINATES collisions and on customer 661's benchmarks
resulted in up to 40% performance improvement for some files with
no performance degradation on any when running a large threshold
array based halftone (as the customer does).
The previous -Z. behavior is retained, although small cache sizes
are of questionable value, and this is sort of confusing since a
small memory build will use the same cache size with and without
-Z.

Fix (images) : Improve coordinate precision when scaling an image (continued).
DETAILS :
Ghostscript Bug 687345 "Image interpolation problem at a band boundary"
This is another partial fix for the bug 687345 for portrait images with Interpolate=true.
Debugged with CET 148-13.
1. The old code inprecisely computes the scaling factor
when interpolating images with Mitchel filter.
The computation was done with the subimage rectangle,
which is different for different bands.
The new code always computes the scale from the entire image rectangle,
which's size is same for all bands.
2. New fields are inserted into gx_image_enum_s and stream_image_scale_params_s
to provide data delivery for (1).
3. In calculate_contrib in siscale.c the variable input_index
is renamed into starting_output_index for a better reflection of its semantics.
4. In calculate_contrib in siscale.c the new variable dst_offset_fraction
is added for a preciser positioning of the filter center,
when it fails between device pixel rows. The old code missed fractional
pixels when stepping to a next band. The expression for its value
was created empirically, so it may need further improvements.
5. Inserted visual trace instructions for easier debugging.
6. Improved the debug trace printing.

Include 12 and 16 bit image support as part of the core graphics
library. Bug 689688.
Details:
Previously, the core graphics library defaulted to including the
'no12bit' and 'no16bit' modules, which contained stubs. These modules
were replaced by full implementations when the psl2lib (12 bit) and
pdfread (16 bit) modules were included.
We now consider this build-time flexibility redundant. The extra code is
not large and the default build generally includes it as these images
are part of all the newer page description languages. We therefore
include the unpack routines directly in libcore and remove the
noi1xbit modules entirely.

Fix (pdfwrite): problems with unusual PDF text rendering modes.
Details:
Bug #689596 "Generated PDF loses an image from original".
Although the PDF interpreter stores both stroke and fill colours,
there is no way to pass both these colours to the graphics library.
The PostScript graphics state may only contain a single colour, and the
device interface only allows for a single colour to be passed.
The old code set the text rendering mode, and assumed that if the
current device was pdfwrite this would be sufficient. However the
need to set both colours causes this to fail.
Modified the pdf_ops to set a show/colour/charpath/stroke combination
instead. The existing code will spot text followed by a charpath of
the same text and collapse it back.
A number of other problems with text rendering modes were also addressed
at the same time, but in a less than optimal fashion. This patch
is a temporary fix while an enhancement is coded to better address
the problem.
(gdevpdts.c) pdf_render_mode_uses_stroke, was checking for render mode
not 0 (fill). Altered to check against the actual stroking modes.
(gdevpdtt.c) pdf_update_text_state was setting the text rendering mode
to 0 (fill) under most conditions. Altered this to set the mode from
the graphics state, unless the current font PaintType is 2 (stroke),
and the render mode is 0, in which case set render mode to 1 (stroke).
(pdf_ops.ps) Modify setshowstate to provide better methods of implementing
various text rendering modes to pdfwrite. Rendering is unaffected by
this change.

Fix (images) : Improve coordinate precision when scaling an image.
DETAILS :
Ghostscript Bug 687345 "Image interpolation problem at a band boundary"
This is a partial fix for the bug 687345 for images with Interpolate=false.
Actually it is related to scaling raher than interpolation.
1. gx_image_enum_begin performed inaccurate coordinate computations,
which caused a different image bias for different bands
due to a wrong coordinate rounding.
The patch replaces it with a better code,
which provides same bias for all bands and for unbanded rendering.
But we're not sure that image placement is now perfect,
because the initial rounding looks strange.
We keep the initial rounding to be compatible with the old code
to minimize raster differences and easier visual analyzis.
For a while we keep the old code in #if 0 because
it may be useful for next patch.
2. image_render_frac contains optimized branches for the case when
image's axes are parallel to page's axes.
Those optimized branches convert parallelograms into rectangles,
except for the last parallelogramm in the chunk.
It caused the last parallelogram to shift in 1 pixel relatively
to the rectangles. This patch adds the optimized branch
for the last parallelogram, so that all image parts
are now placed with same rounding. It avoids rendering artifacts
with 148-05.ps and many other tests. Note that the patch does not fix
the rectangle shift from parallelograms,
so probably it still contain another bug,
which may need a separate fix.
3. While working on this patch we noted that update_strip
doesn't correctly preserve the fractional part for
dda.strip and dda.pixel . We include a track of that experiment
in the new code in #if 0 section for further development.
See comment in code.
4. Inserted visual trace commands for easier debugging.

Fix (graphics) : Interpolated images were shifed in a half of source pixel.
DETAILS :
Bug 687039 "Interpolated images looks strange on Win32 display device".
1. The old code maps the center of the [0,0]th source pixel
to the output image origin. However Adobe maps
the source pixel's corner to the output origin.
This patch compensates the shift when computing the
filter kernel position - see '0.5' when computing 'center'.
2. When the filter kernel scans partially outside the source image,
the math requires to extrapolate source data somenow
to fill the kernel. However the old code performs some strange
computation, which we're not sure what for.
It looks as a rudiment of wrapping the source image
like a thorus. Well, it's an useful math for periodic patterns,
but not for single images. Since we never apply siscale.c to
patterns, we replace this code portion with a simpler one,
which duplicates pixels at image boundaries.
See attachment to the bug to prove that Adobe does so.

Fix ColorValues parameter problem when device has total number of bits (depth)
of more than 31 bits, resulting in a "rangecheck" (-15) error.
DETAILS:
The default get_params would not return -1 for values too large for 32 bits,
but the default put_params tested for this. The rangecheck would show up
on 32-bit devices, such as tiff32nc when running:
"currentpagedevice setpagedevice"
Note that the value returned for ColorValues was platform dependent since
it previously set ColorValues to 1<

Fix (TT): Ignore broken post 2.0 table generated by "Windows Type 1 Installer".
DETAILS:
This is the second fix for bug 689495, that is quite specific
to a TrueType font generated by "Windows Type 1 Installer".
"Windows Type 1 Installer" makes a TrueType font including broken
post table in format 2.0. Previous fix (SVN revision 8351) just
ignores such broken post table, and ISOLatin1Encoding is used
for fallback. When such TrueType font is combined with WinAnsiEncoding,
some glyph names (exists only in WinAnsiEncoding) cannot be resolved.
The post table format 2.0 uses 2 maps to assign a glyph name to
TrueType glyph index: the first map is from TrueType glyph index
to glyph name index (glyphNameIndex[] array), the second map is
from glyph name index to glyph name string (names[] Pascal string
array). The broken post table generated by "Windows Type 1 Installer"
seems to use name[] array by TrueType glyph index directly, and
the glyphNameIndex[] array has unreliable values.
This patch sets /.broken_post when the post table is broken (the
detection of broken post table is same with SVN revision 8351),
then use names[] array by TrueType glyph index when /.broken_post
is set.

Fix (graphics) : Optimize filling a path with a shading color.
DETAILS :
Bug 688970 "(shadings) Optimize filling a path with a shading color".
When filling a path with a shading color, the old code
first intersects the the clipping path with the path,
then intersects the result with the shading BBox.
However the intermediate result frequently appears to be
a big list of rectangles, so the second intersection is slow.
This patch accounts that the clipping path and shading BBox
frequently are rectangles, which are easier to intersect with
no converting to paths. Also the shading box is always a quadrangle,
so intersecting it early gives a smaller intermediate result.
Therefore we first intersect the clipping path with the shading BBox,
then with the path.
This patch keeps the old code within #if #endif
until the full regression testing is passed on the server.
Also would like to eliminate the old complicated function
gx_dc_pattern2_clip_with_bbox, which is still called from elswhere.

Fix: ignore the embedded font resource when PDF interpreter resolves
the unembedded font resource.
DETAILS:
Some PDF generators (e.g. Microsoft Office 2007 add-on to export the
documents to PDF format) emits incompatible font objects with same
resource name. The sample PDF in bug 689637 includes 2 "Times New
Roman" font objects: one is embedded CID-keyed TrueType for Cyrillic
glyphs, another is unembedded WinAnsiEncoding TrueType (possibly for
empty page header or footer). When PDF interpreter resolves latter
unembedded "Times New Roman", external font resource should be used
(Adobe Reader does so). But current Ghostscript uses former embedded
"Times New Roman", because the sample PDF includes "Times New Roman"
without randomization prefix.
To avoid the confusion between embedded and unembedded fonts with
same name, pfont->is_resource flag (=0 embedded, =1 unembedded)
is checked during font object resolution. Even if a cached font
object with same name is found, it is ignored if it is embedded
font. To execute this check in PostScript space (pdf_font.ps),
new operator ".isregisteredfont" is introduced. This patch assumes
that embedded font object in PDF is resolvable by tracking the
indirect object references. If a PDF assumes name-based resolution
of embedded font object (without indirect object), it may be
rendered by external font resource. At present, we don't have
such sample.
By this patch, bug 689637 is fixed.

Fix (TT): Fix a bug in /getinterval_from_stringarray
DETAILS:
getinterval_from_stringarray is a procedure defined to
extract a substring from long table of TrueType font.
When a table is too long to fit into 16bit-length string
object in PostScript, gs_ttf.ps split the table into
the array of strings. When getinterval_from_stringarray
is requested to extract a string which starts in one
member and ends in following member, it returns a string
that only the content of the first member is copied.
There was a wrong conditional that made the substring
extraction aborted. It was fixed to return the correct
substring.
By this fix, bug 689593 (IPA font 2007 edition cannot
be parsed correctly) is closed.

Fix (clist & transparency) : Improve the compositor queue logic (continued).
DETAILS :
The last commit is incomplete due to human error.
Please don't use the last revision.
Bug 689492 "Ghostscript uses a large amount of memory", part 2.
This patch fixes the missed shadow of a text, which is mentioned
in the Comment #8 of the bug report.
1. Added macros for configuring visual trace for easier debugging.
2. The idle transparency bufer allocation condition was wrong.
The patched code allocated ;esser buffers.
3. Found more cases when a mask needs to be released.
4. The old code immediately executes idle masks.
It caused a wrong order for compositor execution
with images that have a soft mask.
With the test case the image's mask was executed before
the group that containing the image.
It caused a premature releasing of a mask,
which preceeeds the group and must noy be released.
The new code delays the execution of idle masks
after all containing groups are executed,
so that the queue is now longer and stores all masks.
We beleive that's not harmful, because
transparency queue elements are pretty small and
work for hos based applications only.
The new function mark_as_idle works for the new logic.
Few aother functions are enhanced with a smarter
processing of the idle flag.
5. Improved comments for the compositor queue logic.

Fix (transparency) : Memory leak after an image with soft mask.
DETAILS :
Bug 689492 "Ghostscript uses a large amount of memory".
When a PDF command stream executes "/d1 gs /d2 gs" where d1 and d2 both define an
untrivial SMask (not important whether they are same mask or different masks),
the second mask replaces the first one, and the first one to be released.
When a transparent group includes an image with a soft mask
(this case happens in the test document for the bug), the image's soft mask must
*temporary* replace the groups soft mask, and the first mask must not
be released.
The old code does not distinguish these cases, assuming that
a mask buffer is being released after rendering a group with it.
Due to that some mask buffers were never released,
causing a memory leak with banded rendering,
because the clist interpreter doesn't run the garbager.
A simpler case for demonstrating the leak could be created with
"/d1 gs /d2 gs" as explained above.
The patch defines a new bool gs_transparency_mask_params_s::replacing,
gx_transparency_mask_params_s::replacing and gs_pdf14trans_params_s::replacing
for passing the necessary information through old interfaces.
Note that as usual we cannot change the device interface for
an easier passing of this info, because we need to maintain
the compatibility with 3d party devices.
Using the 'replacing' flag, pdf14_push_transparency_mask either replaces
the old mask buffer, or creates a new one as a temporary substitution for
an image with a soft mask. In the second case the group mask is
saved in the last transparency stack element in the field
buf->maskbuf. After rendering the image's group
the function pdf14_pop_transparency_group restores
the saved mask buffer, as it was set in the transparency context
before starting the image's mask. For more details see
comments added into gdevp14.c .

Fix (Font renderer) : Horizontal metrics sometimes applied with WMode 1 fonts.
DETAILS :
Bug 689464 "Japanese font writing direction (vertical ?)".
Bug 689646 "vertical text rendered by external CIDFontType0 flows horizontal".
1. When a descendent font of a type 0 CID font has zero FontBBox,
use the FontBBox of the CID font. This is another case when
a 3d party software generates a font with zero FontBBox.
We believe that such font data is incorrect,
but this patch provides a simple workaround.
2. When FontBBox to be used to compute Metrics2,
don't obtain sbw from type 1 glyph descriptions.
The old code does so causing the horizontal metrics
to be used when rendering a WMode 1 font.
3. The case (2) appears to have an exception,
when the font has CDevProc. In this case
we do need sbw from the glyph description
to provide arguments for CDevProc.
See alse the comment added to code.
Note that Type 1 font renderer now depends on some knowledge about type 0 CID font.
But this dependence does not break the configurability
because only an .h file is included into the Type 1 font renderer.

Fix (patterns) : The clipping was wrong with antrivial pattern matrix.
DETAILS :
Bug 687196 "Incorrect pattern processing from Adobe test file pattyp1.ps".
This is a partial fix for the bug, which fixes raster devices only.
1. The old code always sets a canonic rectangular clipping,
which is wrong with rotated or skewed matrices.
Note the patch resets path in the pattern's graphic state.
It is not done in the old code, so it may cause raster diferences.
But it is required in PLRM chapter 8 by the definition of 'makepattern'.
2. Adjust the pattern matrix to pixel grid.
After doing the change (1) the clipping area appears too small for some cases.
It happens because the tile origin falls at fractional pixels,
The new code causes a massive raster difference, which actually is minor
(a shift of some pattern instances in 1 pixel).
Note that PLRM requires to adjust pattern matrix in the definition of 'makepattern',
but doesn't explain how to.
3. In compute_inst_matrix perform computations in 'float'
because the matrix is represented with 'float'.
4. (miror change) Expanded the 'mat' macro for easier debugging with MSVC.

Fix (shadings) : A memory deallocation problem.
DETAILS :
Bug 689660 "memory deallication problems with shadings".
The old code used pdev->memory for temporary storing
an intersection of clipping path with shading bbox.
This is the global memory space.
However if the intersection is trivial,
the path of the clipping path is copied from the
original clipping path, which is allocated in the local memory space.
Later it causes a freeing of path segments to a wrong memory space.
This patch chooses the original clipping path's memory space
when the clipping path is available, and the global space otherwise.

Fix (save/restore) : Compact the changes list against big memory leak.
DETAILS :
Bug 689536 "Memory leak reading PostScript file (PMR 53877).".
The old implementation includes an optimization agains a big CPU time expense
in 'save' and 'restore' for sedtting and resetting l_mark flags.
Normally, when executing 'save', the memory manager needs
to reset l_new marks for objects modified or allocated at the last save level,
so that their further modification on the next save level to be saved
in the changes list. When executing 'restore' these flags to be set
to prevent redundant save.
When the last save level includes many allocations,
the number of scanned objects is big and it causes a significant
time expense. A long ago Ghostscript implements an optimization,
which shorten the scanned list against the big time expense.
However the shortening causes redundant saving.
The redundant saving itself isn't harmful because
it happens seldon and spends a small memory.
However if a redundant save element points to a reference to
a newly allocated array or dictionary, the array or dictionary
can't be garbage collected. When a client executes such allocation and
same reference modification multiple times, all allocated arrays
and dictionaries persist in memory, causing a significant memory leak.
This patch compacts the saved change list whem a significant memory
allocation is accummulated since last save or since last compacting.
The new field gs_ref_memory_s::total_scanned_after_compacting
works for counting allocated elements. The new function
drop_redundant_changes performs the compacting. See comments in its code.
The threshold for starting drop_redundant_changes is choosen arbitrary.
It must not be too small, because the CPU time expense
optimization wouldn't be effective. Also it can't be too big,
because the memory leak recovery would not be effective.
This patch sets it to about 1600000 objects,
which is an experimental trade-of.
Note that this patch reduces the memory leak but doesn't
eliminate it to zero, because more data may be allocated
after the last filtering.
We could implement a filtering within the garbager rather
than withis save/restore. Actually it wouldn't change
the behavior to much, because the threshold would be still needed
against the CPU time expense, It happens because the scanning
deals with array or dictioanr elements rather than with
whole aggregates. Also we don't want to complicate the garbager.
Note that the arbitrary threshold is bigger than neccessary
for the simplified test case included into the bug report.
Due ti that the leak elimination does not happen with this test.
For the compacting to take place the sequence "NEWJOB Z"
to be repeated 90 times rather than 40 in the supplied test.
The customer's test does demonstrate the leak reducing.

Fix (clist interpreter) : Skip idle compositors, step 5.
DETAILS :
This really skips compositors which don't paint anything.
Compositor parameter list structures are extended with a new boolean field 'idle'.
These fields pass information whether something was painted to a compositor.
We choosen this way for passing this info because
(1) we can't change the device inteface with new function arguments, and
(2) we need to pass it through the device chain
(for example, when a clipper is installed onth the overprint device).
This patch only affects the transparency and the overprint.
Other compositors (gsalphac.c, gxropc.c) behave as before.
They may need further improvements.
This patch does not fix the bug 689492.
That fix may be done either before or after this one,
but in any case the patches need to adopt each to another.
The new compositor virtual method is_closing
checks whether a current compositor command
closes an older command, and finds the opening command.
Now we provide untrivial implementations for transparency and overprint compositors.
Would like to define an enum for return values of is_closing.
The old device method create_compositor now passes the 'idle' parameter via
gs_composite_s structure. By default it is false and the behaviour
is same as before. But the clist interpreter is modified
to provide true value when a compositor doesn't paint anything.
To compute this flag the compositor queue now works with its full power.
Note we changed the queue representation with a bilikned list.
This patch entroduces the concept of 'friendly operations'
for compositor operations. These are those operations, which
may interchange with compositor installation/deinstallation.
One example is halftone operations, which always affect
the device below the compositor device, i.e. the target device
of the compositor device. The new compositor virtual method
is_friendly is implemented in an intrivial way for the
transparency compositor especially to exchange with halftone
operations while queueing clist operations.
This especially helps to delay the pdf14 device installation
so that it may completely annihilate with its deinstallation
if nothing is painted through the compositor in a band.
Overprint and transparency compositor implementations
are changed with checking the idle flag.
If it is set, they don't perform neither color blending, nor
raster buffer allocation. Note the pdf14 device maintains the buffer stack
as before, but the allocation of buffers may be skipped.
It saves significant time from cleaning up raster buffers when they are idle.
This patch may need further improvements for the case when
different compositor types are mixed in one queue.
We could not fully test it due to absence of practical tests.
Another useful improvement would be to convert
"0 .inittransparencymask 1 .inittransparencymask dict .setblendparams"
into a single command. It would simplify the compositor queue logic.
Also we think that the name .inittransparencymask doesn't reflect the function purpose.
Will improve someday.
We're not sure whether this patch correctly works with idle masks.
We could not debug it due to no practical cases.
Possibly idle mask will need an additional effort to skip
the group painting to the band.
Also disabled cmd_put_halftone in c_pdf14trans_clist_write_update -
see comment in code.

function in more color spaces, it was never completed, and presents

removing it. It can be reinstated later as a starting point for further

Fix (transparency) : Unwinding the nested masks logic.
DETAILS :
The patch 8340 appears to be optimized for a particular case,
in which a call to pdf14_push_transparency_group
"will have been preceded by pdf14_push_transparency_mask ... pdf14_pop_transparency_mask".
This assumption is not true in general, when the clist interpreter
skips idle groups (either with incoming improvement or
with using the band complexity array).
This patch unwinds the change 8340 and the dependent change 8342.
It also simplifies the garbager descriptor for pdf14_buf_s.

but we intend to close it shortly with a different patch.

Store the posix persistent cache's last modified line as an unsigned

DETAILS:
Previously we used time_t directly, but read and wrote it to the
filesystem using the %ld printf format specifier, which is wrong
on systems where long int and time_t are different widths. Instead
we stort it as an unsigned long int, coercing the return value of
time(). This will be a year 2038 problem on systems with 32 bit longs,
but seems the better option for portability now. There is no cast,
so the compiler should warn if this loses precision.

Improved the previous patch. We need to have a symbol dictionary

Fix (jbig2dec): Missing support for decoding multiple symbols
from a symbol dictionary, when using refinement/aggregation.
Details:
Bug #688945 "jbig2dec FATAL ERROR decoding image: aggregate
coding with REFAGGNINST=2 (segment 0x03)".
Added missing support. When decoding a symbol dictionary, using
refinement/aggregation, and decoding multiple symbols, we need
to use text region decoding (single symbols use refinement
region decoding, already implemented).
This required making the text region decoding procedure available
to the symbol dictionary decoding routine, and correctly
initialising the parameters.
(jbig2_text.h) New include file. The 'Jbig2TextRegionParams'
structure and Jbig2RefCorner enum have been moved here from
jbig2_text.c, and a prototype for 'jbig2_decode_text_region'
created.
Added pointers for the adaptive arithmetic decoder tables to the
Jbig2TextRegionParams structure, as these tables must now be passed
to the decoder routine (see below) rather than initialised in it.
(jbig2_text.c) Modified the 'jbig2_decode_text_region' routine to
take the arithmetic decoder state or data stream (for Huffman
decoding) as a parameter. When being called from the symbol
dictionary decoder we must use the current decoder state; removed
the initialisation of the decoder state, this is passed as a
parameter Removed the initialisation of the adaptive arithmetic
decoder tables, these are now passed as part of the
Jbig2TextRegionParams structure.
Modified 'jbig2_parse_text_region' to create and initialise the
arithmetic decoder state (or data stream for Huffman). If
using adaptive arithmetic encoding, create and initialise the
tables.Required now that these are parameters to the text
region decoder.
(jbig2_symbol_dict.c) 'jbig2_decode_symbol_dict', when we
encounter refinement/aggregation with REFAGGNINST > 1, instead of
flagging an error create a Jbig2TextRegionParams structure (if
not already present), initialise the arithmetic decoder tables, and
call the text region decoder to create the bitmap. If we already
have a Jbig2TextRegionParams structure (because we have already
decoded a symbol this way) just use it as the argument to the
text region decoder.

Fix (clist interpreter) : Skip idle compositors, step 3.
DETAILS :
The clist writer writes the 'create compositor' operation to all bands,
including ones that are not covered by a transparency.
It does so because this operation changes the number of color components.
When rendering a specific band, it frequently happens that a compositor
is created and then immediately destroyed. Such thing happens outside
the transparency bbox, and within the transparency bbox if
the band has no transparent objects. When compositor is created,
it allocates a big raster buffer and cleans it.
Due to that we observe a significant CPU time expence
when running the test case of the bug 689155.
This patch is a preparation for further improvements.
This patch includes CTM into pdf14 compositor params
(see changes to c_pdf14trans_read, c_pdf14trans_write, clist_create_compositor).
The result should be same as the old code, but the algorithm is different.
The old code wrote CTM as a separate command before cmd_opv_ext_create_compositor.
The new code does not, and in many cases compositor commads
immediately follow each another.
The last fact changes the behavior of the compositor queue :
before this patch it consisted of 1 element maximum,
but after it the queue becomes longer (up to 10 elements
with SoftMaskGroup.pdf). A bug is fixed in the queue logic
in gxclrast.c ln 1355.
The queue is still immediately executed
when a non-compositor command appears in the input stream.
An annihilation of neighbour idle compositors will be a next step.
Minor changes:
- added a new method adjust_ctm to gs_composite_type_procs_t.
- added type checks with composite_*_proc macros to all compositor types.
- dependencies were broken for gdevp14.c in lib.mak .

recomputes color for each pixel.
The new code checks whether neighbour pixels have same color,
and if so it finds the color change position
with solving a linear equation,
and fills entire constant color interval
without computing color for each pixel.
The linear equation is solved with 64 bits arithmetics.
We would like to create a 32bits algorithm someday.
We think it is possible with rounding colors to 16 bits
and restricting a run length with 15 bits.
Note it must not accummulate rounding errors,
so it needs to compute from the run start at each iteration.
So if the scanline is wide, first split it into smaller ones
by coordinates, then break each subscanline into runs by color changes.

Fix (shadings) : Optimize path manipulations for shading fill (continued).
DETAILS :
Debugged with the test case of the bug 689155.
A long ago the graphics library converted the sfill clipping into a path.
It was improved with revision 8017 with introducing
a device response for pattern_manage__shfill_doesnt_need_path.
However the revision 8017 appears incomplete :
it missed the related change to the clist writer device
and to pdf14 device. This patch fixes it.
This patch causes a progression for the problem
known as bug 689338 "Raster depends on bands".
With banded rendering some shadings are now painted some wider,
and the raster appears equal to one from unbanded rendering.
It happens because the old code doesn't convert shfill clipping
into a path when no banding, and does convert when banding.
The new code does not convert in both cases.

Fix (graphics) : Improving the setoverprint logic.
DETAILS :
Debugged with the test case of the bug 689155.
This eliminates unnecessary calls of dx_device::procs.create_compositor.
In the test case the oprator 'show' calls gs_save and gs_restore
and the latter performs unnecessary call to gs_do_set_overprint
due to overprint is set at page start. It causes a significant CPU time expense
while clist interpretation.
We're not sure why the old code is such,
we change it as we think correct.
Will see the regression test results.
A local test gave no differences.

Fix (pdfwrite): Fonts containing glyphs with no sbw or hsbw
instruction caused pdfwrite to crash.
Details:
Bug #689544 "Segmentation fault writing PDF file".
The job contains a number of fonts apparently converted from
TrueType to type 1. The /.notdef glyph in every case consists
only of an endchar instruction. Techincally invalid since the
specification says the first instruction must be either an sbw
or hsbw instruction.
This causes a crash because gs_type1_glyph_info didn't create
a path before interpreting the glyph. If we encountered a path
operation before a sbw instruction we attempted to write to the
non-existent path.
(gxtype1.c), gs_type1_glyph_info, create a path for the type 1
interpreter to work with. Make it a bbox_accumulator so we don't
allocate memory for path segments.
(gdevpsfu.c), psf_check_outline_glyphs, if we get an invalidfont
error return from the font's 'glyph_info' procedure, don't exit
immediately. Check each glyph, and only return an error if
there are no good glyphs.

Incompatible changes
The default device on unix-oriented builds was temporarily switched to
the bbox device in the 8.60 release. In the 8.61 release, the
default was changed again to the x11alpha device, if X11
support is available, and otherwise falls back to the bbox device.

Revert the change to using an environment variable for the MSVC LIBPATH.
Details:
This wasn't effective in addressing the problem and could cause
additional trouble if the environment isn't configured. The changes
in r8394 should properly address the issue of quote interpretation
with MSVC6.

Fix (clist interpreter) : Transparency caused a wrong color depth.
DETAILS :
Bug 689520 Regression: 1bpp and grayscale output broken.
The clist interpreter clist_playback_band maintains 2 devices :
the clist reader and target. The clist reader device stores
private interpreter's data. However using a device structure
for this purpose is pretty confusing, because the target
device may have same device fields with different values.
Particularly while processing a transparency, the target device
chage to a transparency buffer device,
which may have a different number of color components.
The problem happens due to the clist interpreter used
a wrong device to obtain the number of color components.
This patch changes the code with taking color components
from the target device.
Now we don't try to analyze all other access to the clist device -
it should be a subject of a separate job.
Therefore the code may need further improvements.
The right way would be to define a special structure for the clist interpreter,
and to drop the clist reader device at all.

Fix dependency problems that caused obj/gs_init.ps to be missed. Also fix a
typo that caused CMap files to be missing.
DETAILS:
This method of putting the gs_init.ps dependency down in lib.mak require
us to get gs_init.ps. This hack was discussed with Ralph and is an
alternative to adding a dependency to all of the top level makefiles.
The dummy gs_init.ps is only made when we are NOT including the PS
interpreter (PSI_INCLUDED) since we need the real one for the language
switch build. Note that the dummy file doesn't get added to the %rom%
file system since PS_ROMFS_ARGS is empty if int.mak is not included.

Fix (clist) : Providing clist instruction ids and offsets to debug trace (continued 2).
DETAILS :
The last patch (rev 8365) appears incorrect and causes crashes with halftoning devices.
The problem happens due to gx_device_clist_reader::offset_map
has been initialized too early in clist_reader_init.
At that moment the device is still a clist writer,
but the field offset_map belongs to clist reader.
Due to gx_device_clist_s is a union, the field overlaps band_range_list.head,
and the letter was prematurely reset. It caused some commands were not written
to clist file while the page closes. With the test case (pbmraw -r300 012-01.ps)
it missed cmd_opv_ext_put_halftone and did not miss cmd_opv_ext_put_drawing_color
with color index type == ht_binary. It caused the crash in gx_dc_ht_binary_readdue to
pis->dev_ht was not set. (cmd_opv_ext_put_halftone does set, but it was missed).
The log message of the revision 8365 reads :
"This change is algorithmically equivalent for release build."
This statement is false due to the premature initialization of
gx_device_clist_reader::offset_map.
This patch fixes that with removing its initialization from
clist_reader_init. A subsequent call to clist_render_init initializes it.
The last patch was made buggy due to the function name
clist_reader_init does not properly reflects its finction.
This patch fixes the naming.
Also provided more stability in gxht.c with a check for NULL pointer.

Fix (clist) : Providing clist instruction ids and offsets to debug trace (continued).
DETAILS :
The last patch appears incorrect for the debug build
and causes crashes sometimes. Not sure why local testing didn't detect that.
This change is algorithmically equivalent for release build.
In the debug build it fixes problems of the last patch.
1. Offset map could be prematurely released by the garbager
(It could cause a crash. Not sure why the local test didn't detect it).
A new pointer gx_device_clist_reader::offset_map prevents that.
Added it to the garbager descriptor and provided its initialization.
2. buffer_segment_index can fail with returning a negative index.
Checked that and propagated error codes.
4. Besides top_up_cbuf, the buffer topping up also happens
with calling memmove when reading bitmap data.
Added calls to top_up_offset_map for accounting that.
5. See comment in top_up_offset_map about the improved invariant.
6. The prototupe of top_up_cbuf is changed with passing the error code.
Due to that the variable 'cbp' is droped the 'register' modifier.
We believe it won't cause a visible slowdown because
modern compilers are smart enough.
7. Do not maintain offset_map when -ZL is not specified.
It saves some CPU time with debug build.

Fix (clist) : Providing clist instruction ids and offsets to debug trace.
DETAILS :
This change is algorithmically equivalent for release build.
In the debug build it only adds a new debug printing.
Let clist segment is consecutive instuctions buffered for same band.
1. gx_device_clist_writer::ins_count counts clist segments.
2. cmd_prefix_s::id is the number of clist segment that it belongs to.
3. stream_band_read_state_s::offset_map stores a table for mapping
clist segments' buffer offsets to clist file offsets.
4. s_band_read_init_offset_map, s_band_read_dnit_offset_map,
clist_file_offset, top_up_offset_map maintain the table.
5. Inserted a debug printing into gxclutil.c, gxclrast.c .

Fix (clist) : A preparation for providing clist instruction ids and offsets to debug trace.
DETAILS :
We would like this change to be algorithmically equivalent,
but the proof is too complex. Therefore we commit it separately
in order to check for raster differences.
1. Inserted a new field into cmd_prefix_s.
For now this field is never used, but it changes memory allocation.
Due to that the bufferring in the clist writer goes slightly different.
Particularly it may cause new effects while restarting failed instructions.
2. Early return from top_up_cbuf when the stream is over.
The new code does not top up the last portion of the data stream.
It shouldn't be important for the reader, but we can't proove for sure.
This change is necessary because we want to add more fields to gx_clist_state_s,
and the new fields would be invalid after s_close resets stream::state.
See the next patch for details.

Fix (pdfwrite): type 3 fonts with exceedingly small BoundingBox
entries were clamped to 0 or 1.
Details:
Bug #689537 "FontBBox wrong in pdf generated by ps2pdf (breaks
acrobat 8)".
The type 3 font has a FontBBox of [0 0 0.3 0.3]. Because
pdfwrite uses integers to record the font bounding box, this was
being clampled to [0 0 1 1]. This should not cause a prolem, but
for unknown reasons causes Acrobat 8 to render *very* slowly.
(gdevpdtf.h), 'struct /*type 3*/', alter the FontBBox member from
a gs_int_rect to a gs_rect to preserve floating point box values.
(gdevpdtt.c), pdf_make_font3_resource, copy the font bbox values
instead of floor'ing the lower and ceil'ing the upper values.
(gdevpdfu.c), create a new function 'pdf_write_font_bbox_float'
to write the bbox as floats instead of ints.
(gdevpdfx.h) prototype 'pdf_write_font_bbox_float'

routine to write out a floating point bounding box.

Fix (pdfwrite): named objects, created via a pdfmark such as /BP,
could not have their content modified after the object was completed.
DETAILS:
Bug #689104 "Overwriting transformation /Matrix in XObject previously
created with /BP & /EP pdfmarks".
Some pdfmarks, such as /BP create named objects. These can accumulate
information until a matching pdfmark (/EP in this case) completes the
object. When complete, objects were written to the final destination
PDF file. This made it impossible to later modify the object.
(gdevpfm.c) pdfmark_bind_named_object, change the call to
pdf_substitute_resource to defer writing the object to the
destination file, if the object is named. This means the object is still
available for modification until the end of the job. NB if the object
is not named, we still write it immediately, as there is no mechanism
for modifying an unnamed object, nor do we currently have a mechanism
for maintaining a record of unnamed objects.

Fix: Ignore problematic post table in format 2.0 with ISOLatin1Encoding glyph names.
DETAILS:
Some TrueType fonts converted by "Windows Type 1 Installer" have
problematic post table format 2.0 including MacGlyphEncoding
entries which should be omitted. Such extra entries in the
beginning of glyphName array make /Encoding broken. By checking
if glyph name in post table is predefined one in MacGlyphEncoding,
such problematic post table can be detected. By ignoring such
problematic post table, bug 689495 is fixed.
However, some TrueType fonts designed for Microsoft redefines
MacGlyphEncoding glyph name out of predefined range. To permit
such font, the post table in format 2.0 is checked by
ISOLatin1Encoding which is the cross section of MacGlyphEncoding
and WinAnsiEncoding. ISOLatin1Encoding is enought to fix the
bug 689495.

Change pdf_base.ps::.pdfrun and pdf_sec.ps::.decpdfrun to ensure
"PDFScanRules" == "true" while scanning the PDF, and if necessary revert
it back to "null" before returning. Thanks to SaGS for the patch. Bug 688598.
DETAILS:
The bug is triggered by the construct "//DeviceGray" found in the sample PDF.
The following command fails with the same error as GSView, and for the
same reason:
pdfopt.bat media_365163.pdf output.pdf
When Ghostscript interprets a PDF directly, most of the job is done by
LIB\pdf_main.ps::dopdfpages which sets "PDFScanRules" correctly. However,
the initial part of scanning the PDF (trailer dict, ...), and the rebuild
logic scan the PDF with wrong "PDFScanRules". Also GS's own various tools
and GSView don't set/ reset it as needed.
Implementation details:
(A) ".pdfrun" and ".decpdfrun" dinamically construct procedures that do the
real work and immediately execute them. The patch changes these procedures
to include setting/ restoring "PDFScanRules". If "PDFScanRules" == "true"
already, then "setuserparams" is not called at all, so normally
(when ".[dec]pdfrun" executed during "dopdfpages") there's practically no
impact on performance.
There are also "token" calls outside these 2 procedures, but these calls are
for scanning the xref and "# # obj" lines, which don't contain PDF name
objects.
(B) ".getuserparam" GS-specific operator changed to recognize scanner options
too ("PDFScanRules" and "PDFScanInvNum"). This is needed by ".[dec]pdfrun"
for restoring "PDFScanRules"; also used for an optimization (to omit calling
"setuserparams" when not actually needed).
Note:
For "Process[DSC]Comment" it returns "true" if a procedure
is set, and not the actual procedure. To retrive the
procedures (or null if none set), use "currentuserparams".
(C) ".currentuserparams" is NOT modified, so it does not return scanner
options. If it did, these ended up being put into "userparams" and be
affected by "save"/ "restore" (see the redefinition of "restore" in
gs_lev2.ps).

Stop reading the xref+trailer at the closing ">>" because PDF 1.7 Reference
made "startxref" optional in some cases. Thanks to SaGS for thr patch.
Bug 688283.
DETAILS:
The PDF 1.7 Reference, section F.2.3 "First-Page Cross-Reference
Table and Trailer (Part 3)", 2nd paragraph on page 1031 states:
"The first-page trailer may optionally end with startxref, an
integer, and %%EOF, just as in an ordinary trailer. This
information is ignored."
(note the word "optionally"), so in such a case a PDF interpreter
cannot rely on anything particular (like "startxref"/ "startref"/
"xref") to follow the trailer dictionary. Now consider a linearized
PDF being incrementally updated, and you get that in the general
case a "previous trailer" may lack the "startxref". Apparently,
Acrobat does a similar thing when creating hybrid-ref PDFs.

Fix (pdfwrite): Type 1 CharStrings could be converted to invalid
type 2 CharStrings if the glyph program used implicit start points
for subpaths.
DETAILS:
Bug #689055 "pdfwrite creates a bad Type1C font"
If a type 1 CharString used an implicit point, either the initial point
(0,0) or the point resulting from a closepath, then the type 2 output
code duplicated this. Unfortunately this is illegal in type 2 CharStrings
where each subpath must begin with one of the 'move' instructions.
(gdevpsfx.c) psf_convert_type1_to_type2, create a new boolean variable
'need_moveto' initialised to true. When we encounter a move operation,
set it to false. When we encounter a closepath, set it back to true.
Thus this variable is always true at the beginning of a subpath, and
becomes false as soon as a move instruction is encountered.
While converting type 1 CharStrings, whenever the current instruction is
a line drawing operation, if 'need_moveto' create a move instruction,
taking account of any pending glyph widths.
This is only performed on the second (conversion) pass through the type 1
CharSrtring as we don't need to worry about this during the first (hint
collection) pass.

Use the proper build machinery to link to cups.
DETAILS:
Previously, the configure script just appended the output of cups-config
to CFLAGS and LIBS which could confuse other parts of the build. The
LIBS setting was actually ignored by cups.mak which hard coded liking
to cups and cupsimage through the genconf -lib option, although it
depended on it for the search patch if cups was in a non-standard
location.
Instead, we parse the output of cups-config to separate the dependent
libraries and additional search paths if any, and pass those through
to genconf in the intended way. This destroys the order of the link
line, but GNU ld, at least, applies all -L paths to all -l libraries,
so that should not distrurb the build. We pass any extra include paths
in a special variable and use it directly when compiling gdevcups.c to
avoid confusing the search path for other components.
Configure also used to ignore cups-config if it found cups/raster.h in
the current search path. We now prefer cups-config.

Abstract the autoconf build's link line flattening for generic use.
DETAILS:
The Ghostscript build system expects a list of bare library names
for specifying library dependencies through the .dev files to
genconf. The configure script had some code to decompose the usual
unix-style "-lX11 -lXt" link flags returned by AC_PATH_XTRA.
As we've added more optional external libraries to the autoconf
build, this has become a general need, so the code is now abstracted
into an autoconf macro for use elsewhere in the configure script.

Fix (pdfwrite) : An integer arithmetic overflow while converting Type 1 CharStrings into Type 2.
DETAILS :
Bug #689106 "Wrong charpath direction in PDF"
Patch from Rolf Becker with minor improvements.
A processing of big integers was implemented in gstype1.c
while rendering a glyph, but it was not implemented
in pdfwrite while converting a Type 1 font into Type 2.
It caused an incorrect glyph outlines embedded into PDF.
This patch factors out the old processing as a new
function gs_type1_check_float and applies it in gdevpsfx.c .
The function prototype is added to gxtype1.h as it needs to be public.
The patch also improves comments in code
because now we understand better what happens in there.
For more details see comments in code.
The change to gstype1.c is algorithmically equivalent
except inserting a new check for overflow in float2fixed.
The new check may fail when the old code
renders an incorrect outline.
We have no practical cases that demonstrate it.

ps2write: When encountering font names which contain unfortunate characters
such as white space, or delimiters, emit the name as an escaped string and
'cvn' instead of a literal name.
DETAILS:
Bug #689420 "Errors with ps2write and special chars in FontName"
Patch from SaGS with some minor improvements.
Fonts whose name contains white space, or delimiter characters (eg /,(,[ etc)
were being written into the type 1 font stream using the name unchanged. This
causes the resulting PostScript to fail on any PostScript interpreter. The
exact error varies depending on the placement of the invalid character and
the following data.
This is now handled by emitting the font name as a string, and using the cvn
operator to convert the string to a name, escaping characters if required.
Note that both the C portion of the code needs to change, in order to write
escaped names, and the PostScript prolog in order to undo any name escapement.
1. (gdevpsf1.c) write_font_name, check to see if the font name contains any
characters which we need to escape. If so, then use the existing routine
's_PSSE_template.process' to convert the name to an escaped character
sequence.
Update the write_font_name routine so that it optionally writes a name
to the output. If the name does not need escaping, then simply prepend a
'/' to make a literal name, otherwise append a 'cvn' to convert the
escaped string to a name. When writing out the font header we just need
the font name as a human readable string. When writing the /FontName
entry in the font dictionary we need a PostScript name, either a literal
or a PostScript escaped string converted to a name. (see below)
2. (gdevpsf1.c) psf_write_type1_font, alter the use of write_font_name in two
places. Firstly to emit the name as part of the font comment, secondly to
put the name as the value for the /FontName key in the fotn dictionary. In
the first case we write it as a simple string, in the second as a name.
3. (opdfread.ps) The TypeDameons procedure extracts the FontName from the Font
dictionary in the body of the job. Since the FontName can now be escaped,
we need to undo the escapement before defining the font. Firstly we define
a new procedure 'UnPDFEscape', secondly we call this when dealing with the
FontName and the BaseFont keys, in order to convert the escaped name back
to a normal name, so that the font can be found with findfont.

DETAILS:
Bug #688783 "commit 6892 mis-uses the TZ environmental"
A rather lengthy thread, but in essence quite simple. A change to calculate
the system local time as an offset from UTC, and store this information in
the form described in the PDF Reference (Section 3.8.3 "Dates" on p133 of
the 1.6 PDF Reference).
The patch uses code supplied by SaGS.
(gdevpdf.c) pdf_initialize_ids, use the C runtime 'time' and 'gmtime' to
determine the difference between local system time and GMT. Use this to
calculate the difference (positive, negative, or none) from GMT, and the
number of hours and minutes comprising the difference. Use 'localtime' to
find the local system date and time.
Take all of the information from above, and format the result according to
the specification in the PDF Reference:
(D:YYYYMMDDhhmmssZhh'mm')
Where YYYY=4 digit local time year
MM=2 digit local time month
DD=2 digit local time day
hh=2 digit local time hours (24 hour)
mm=2 digit local time minutes
ss=2 digit local time seconds
Z=offset of local time from UTC
Z=no difference

Added code to the pxlcolor device (gdevpx.c) to set the color space even
if the test for "portrait transformations" fails.
DETAILS:
The pclxl_begin_image() function performs a rather complicated test to
see if the image transformation can be "handled" (line 1434). If this
test fails the routine falls through to using gx_default_begin_image().
However, in this case the pcl-xl color space is never set and if
the previous color space was eGray the pcl-xl stream will fail with
ExtraData (because 3 times as much data as expected will be written).
Presumably the inverse is also true, but I don't have a test case for it.
The solution is to call pclxl_set_color_space() in the use_default
case (a possibly more correct solution would be to call
pclxl_set_color_palette()).

Fix (stroking) : Prevent installing an extra clipper device, step 2.
DETAILS :
Bug 689427 "Superposed clippers".
The last patch doesn't fix the problem when stroking
a path with a shading color.
The new code distinguishes 3 cases :
1. When painting happens through low level device methods
which don't accept a clipping path. It happens inside
stroke_fill, so the new code passes the clipper device to it.
2. When the painting happens through fill_path,
which does handle a clipping path. It happens inside
FILL_STROKE_PATH, so the new code doesn't pass the clipper to it,
but passes the clipping path as it worked before the last patch.
3. When the stroking algorithm is called from 'strokepath',
don't need a clipping at all. This case works as before,
but the new code doesn't construct a clipping device.
Minor change : Added a new argument 'dev' to the macro
FILL_STROKE_PATH to simplify the code understanding and debugging.

Fix (pdf14 device) : Optimize the buffer backdropping, step 2.
DETAILS :
1. Intersect the backdrop rectangle with the bbox of a real painting to the transparebcy buffer,
which is accummulated from pdf14_fill_rectangle. It reduces the rectangle for a faster blending.
1.1. Removed min_int, max_int from pdf14_buf_new against an integer overflow when computing
sizes of rectangles.
1.2. Do intersect rectangles in In pdf14_put_image, pdf14_cmykspot_put_image, pdf14_custom_put_image.
2. dump_planar_rgba still could access outside the buffer due to a recent patch is incomplete.

Fix (pdf14 device) : Don't allocate transparency buffer for bands that appear outside the transparency bounding box.
DETAILS :
This is an optimization, which should be algorithmically equivalent.
For bands outside the transparency bounding box the old code
allocated a zero length buffer and performed fake operations with it.
The main change is gdevp14.c ln 550.
Others prevent an access to the buffer when it is not allocated.
Note that in some cases the new check is excessive
because (width <= 0 || height <= 0) normally means no buffer.
We check for (buf->data == NULL) anyway to simplify the sefity proof
and documentation.

DETAILS :
Bug 689498 "transparency: The buffer backdroping code can write outside bufers.".

This patch ports the revision 7064 changes from pdf14_put_image to
pdf14_cmykspot_put_image and pdf14_custom_put_image, which were added
after the revision 7064. They need same improvement, which was mised
due to a development miscoordination.
This change is committed without any testing,
because the author has no test cases which involve
pdf14_cmykspot_put_image and pdf14_custom_put_image.
Possibly they need to build Ghostscript with special options
and to run the test case of the bug 688631 with special devices.

Fix (FAPI / UFST bridge) : A crash when processing an embedded CIDFontType 11.
DETAILS :
Debugged with running the test case of the bug 689471 with FAPI.

- /HookDiskFonts [1 2 9 11 42] % FontType values for disk PS fonts to be redirected to FAPI.
- /HookEmbeddedFonts [1 2 9 11 42] % FontType values for embedded PS fonts to be redirected to FAPI.

+ /HookEmbeddedFonts [2 9 11 42] % FontType values for embedded PS fonts to be redirected to FAPI.
because UFST still can't handle embedded Type 1.
This patch passes impl_PCLchId2ptr as p_PCLglyphID2Ptr argument.
We believe it is correct for True Type,
but we're not sure about Type 1,
because Type 1 composite glyphs refer subglyphs
in an inobvious way - see Type 1 specification.

pdfwrite: Allow downsampling of images in a /Indexed colour space, provided the
downsampling type is 'subsample'.
DETAILS:
Bug 689265 "PDF created by GS 8.57 is much larger than from competitive creator"
The original job contains several images, including one large one, which are in a
/Indexed colour space. We can't use average or bicubic downsampling with /Indexed
colour space, because the colours in the space may not be linear. It ought to be
possible to use subsampling though.
Where we previously checked the image colour space and decided to disable downsampling
if the colour space was /Indexed, we now additionally check the downsampling type
and permit it if the type is 'Subsample'.
(gdevpdfi.c) pdf_begin_typed_image, check the downsample type as well as the colour
space before deciding not to allow downsampling.
(gdevpdsi.c) psdf_setup_image_filters, check if the colour space is /Indexed before
deciding which set of image parameters to use (2 places). Also, if we do encounter a
/Indexed space, make the compression filter into Flate to ensure we don't try and use any
kind of JPEG compression, which may not work properly with Indexed spaces, and in any case
is not the most appropriate type of compression in this situation.

pdfwrite: when encountering a glyph in a type 3 font for which no Charproc is defined
emit a simple setcachedevice operation instead of an empty stream.
DETAILS:
Bug #688834 "Undefined characters in Type 3 fonts cause PDF conversion to fail"
The original report, based on an older version of pdfwrite, states that an error occurs with
pdfwrite when using glyphs from a type 3 font where there is no charproc defined for the
glyphs.
In fact, with the current version of pdfwrite, no error occurs, but the resulting file
causes Acrobat to give warnings and display the result incorrectly. NB other PDF consumers
do not behave this way.
This appears to be caused by pdfwrite emitting an empty stream (length 0), because no charproc
is captured for the glyph (since it has none). For some reason Acrobat takes exception to this.
A simple solution is to write a stream which is not empty. The sequence '0 0 0 0 0 0 d1'
, a
setcachedevice with arguments all 0, resolves the problem.
(gdevpdtt.c) In pdf_text_process, after capturing a Charproc for a type 3 font, check the length
of the stream. If it is 0 bytes, then emit '0 0 0 0 0 0 d1' and carry on.

DETAILS :
Bug 689068 "ps2pdf13 fails with Error: /invalidfont in --ashow--".
The document could successfully rasterize,
but failed with invalidfont when converting to PDF.
It happened due to a missed glyph,
which is not atually used in the doeument.
The patch skips font errors that do not belong to the font subset.
However if the user requests to embed a complete font,
a warning is printed to stderr and the document fails
due to the font error as before the patch.

1. gdevpdtb.c : Process a coplete font copy error as explained above.
2. gsfont.c : Ignore missed glyphs when computing the "fixed width" font feature.

pdfwrite: Convert 'text' followed by 'text charpath stroke' to a single text
operation by using text rendering mode 2.
DETAILS:
Bug #689310 "Offset between text and outline in pdfwrite.dev"
Emitting text, followed by the same text as an argument to charpath, and then stroking the
resulting path previously resulted in a large path being emitted and stroked in the PDF file.
This is inefficient, but worse the path is not grid fitted, whereas the text is. When
used to stroke the outline of previously rendered text, either in a different colour or to
create a 'bold' effect, the emitted path did not always precisely match the rendered text.
This change is to emit this PostScript construct using the closest available match in PDF,
which is the text rendering mode. There are two parts to this change, firstly to identify
when a path is the result of a charpath, and secondly to merge text followed by charpath/stroke
operations into a single operation on output.
1. (gzpath.h) Add a new member 'last_charpath_segment' to the gx_path_s structure. Update the
path garbage collection code for relocation of new variable.
2. (gxpath.c) Initialise the new member 'last_charpath_segment' to 0 in
gx_path_init_contents, and also in path_alloc_copy to prevent copies being identified as
the result of a charpath.
3. (gxchar.c) We need to be able to tell if a path was the result of a charpath. To do this
we store the final segment of a path in 'last_charpath_segment' of the path
structure during show_finish, if the current operation was a charpath. See also item 11.
4. (gdevpdfx.h) Add a new member 'last_charpath_op' to the gx_device_pdf_s structure, to
hold the boolean argument associated with a charpath operation. Also add to the
pdf_substream_s structure to allow us to save and restore this value on entry to or
exit from a PDF substream.
5. (gdevpdti.c) Save and restore the value of last_charpath_op in pdf_enter_substream
and pdf_exit_substream.
6. (gdevpdfx.h) Add a new member variable 'last_charpath_op' to the 'pdf_substream_save_s'
structure to allow us to save and restore the last_charpath_op as noted above.
7. (gdevpdtt.c) During gdev_pdf_text_begin, if the operation is a charpath, check the
following conditions, if met then store a copy of the charpath boolean variable in
a new member of the gx_device_pdf_s structure.
1. Operation must be a charpath
2. Current path must be empty (can't handle charpath concatenated to existing path)
3. The font being used for the current text must be the same as the font used for
the previous stored (but not yet emitted) text.
4. The initial point of the text for the charpath must match the initial point of
the previous stored text.
5. The text bytes must be the same as the previous stored text.
6. The point size of the text must match the previous stored text.
Also, move the calculation of the font point size out of pdf_update_text_state so that
we can calculate the size in pdf_compare_text_state_for_charpath' defined in 9 below
without duplicating code.
8. (gdevpdtt.h) Prototype 'pdf_calculate_text_size'
9. (gdevpdts.c) Add a new function 'pdf_compare_text_state_for_charpath' to do the
checking noted above. The pdf_text_state_s structure is not defined publicly, so
we need code to access its members. Also add a function 'pdf_modify_text_render_mode'
which will attempt to add a rendering mode (stroke, fill or clip) to existing text
by updating the existing text rendering mode. Returns 0 if the existing text cannot
be modified, and we fall back to emitting a path and stroke.
10. (gdevpdts.h) Add prototypes for the functions required in 9.
11. (gdevpdfd.c) In pdf_stroke_path, if the 'last_charpath_op' member of the pdf device
structure is set, perform some more checks (below) and if passed, set the text render
mode of the stored text, set the stroke colour, set the line width, and force the stored
text to be emitted. This conveniently results in a gsave/grestore pair round the
graphics state changes.
1. The last charpath operation must have been 'false charpath'
2. There must be a non-empty path (result of the charpath operation)
3. The 'last_charpath_segment' stored in the path must match the actual last segment
in the path. (can't handle path segments added to the result of a charpath)
12. (gdevpdfg.h) Make the pdf_reset_color routine public, as we need to be able to set the
colour from pdf_stroke_path.
13. (gddevpdfg.c) We need to be able to set a stroke colour while in a TEXT context,
previously the routine pdf_reset_color, which emits colours and spaces, immediately
switched to a STREAM context, which caused pending text to be flushed. pdf_reset_color
was only called from two places, pdf_set_drawing_color and pdf_set_pure_color. The
switch to a STREAM context has been moved to these routines, leaving pdf_reset_color to
actually do the work without worrying about the context.
It was found necessary to also reproduce some checks before switching context, to
prevent unnecessary context switches.
Removed unused local variable 'process_color' from pdf_reset_color.
There is scope for additional enhancement with this code. Presently there is no attempt to
deal with 'charpath gsave fill grestore stroke' constructs, nor to handle clipping paths
resulting from charpath. There may be other possibilities.

Fix: (TT font handler) : Use given prebuilt_encoding when Apple Roman TrueType cmap subtable is chosen
DETAILS:
As current implementation assumes /prebuilt_encoding[] is
compatible with WinAnsiEncoding when Microsoft UCS2 TrueType
cmap subtable is chosen, current implementation assumes
/prebuilt_encoding[] is same with MacRomanEncoding when
Apple Roman TrueType cmap subtable is chosen.
/prebuilt_encoding[] is completely ignored and the inverse
of MacRomanEncoding is used. Therefore, when Apple Roman
TrueType cmap subtable is chosen but /Encoding is
StandardEncoding or PDFDocEncoding, some characters are
shown by wrong glyphs. This patch uses /prebuild_encoding[]
if it's given, when Apple Roman TrueType cmap subtable is
chosen.
According to PDF Ref 1.7 p. 431, MacRomanEncoding does not
cover all characters in Apple Roman TrueType cmap subtable,
16 characters are missing. To exploit the glyphs as many
as possible via Apple Roman TrueType cmap subtable, this
patch introduces "MacRomanEncodingForTrueType" including
missing 16 characters. By this change, 16 glyphnames
can be exploited via Apple Roman TrueType cmap subtable.
There might be broken TrueType fonts that use the names
in MacRomanEncoding at incompatible 8bit charcode. The
text drawn by such fonts would be broken, the results are
unexpected.

Fix: Preprocess the glyphnames in prebuilt_encoding by AdobeGlyphList for Microsft UCS2 cmap subtable
DETAILS:
According to PDF Ref 1.7 p. 430, Adobe modern products
always prioritize Microsoft UCS2 TrueType cmap subtable
regardless with /Encoding, as far as the font is declared
as Nonsymbolic by /Flags. For example, even if /Encoding
is MacRomanEncoding, Microsoft UCS2 TrueType cmap subtable
is prioritized than Apple Roman TrueType cmap subtable.
The encoding of Microsoft UCS2 TrueType cmap is not a
superset of MacRomanEncoding, see PDF Ref 1.7 Appendix D.
Current implementation expects the content of /Encoding
is always compatible with chosen TrueType cmap subtable,
thus unexpected mismatching causes loss of glyph like:
bug 689351 "Content Loss for certain Embedded Type42 Glyphs with gs8.57"
When Microsoft UCS2 TrueType cmap subtable is chosen,
the glyphnames used in /prebuilt_encoding[] should be
preprocessed: the glyphnames changed to the charcode
compatible with Microsoft UCS2 encoding scheme, before
combining with charcode-glyph mapping table in Microsoft
UCS2 TrueType cmap subtable. The preprocessing should
be done by AdobeGlyphList that maps known glyphnames
to UCS2 charcode. The unknown glyphnames are left to
second processing in /.pdfmapchars. This preprocess
fixes bug 689351.
There might be broken TrueType fonts that use the names
in AdobeGlyphList at incompatible UCS2 charcode. The text
drawn by such fonts would be broken, the results are
unexpected.

Fix : A crash in garbager after clist playback fails in image.
DETAILS :
This problem was occasionally detected when disk overflow happens with
the test case of the bug 689440.
device_clist_enum_ptrs, device_clist_reloc_ptrs process
gx_device_clist::writer.clip_path when image_enum_id is not zero.
The clist playback code sets it when processing an image.
We guess it was done to avoid redundant clist writing,
and we think it's not a best way to do that.
If an image processing fails with an error,
the old code does not reset image_enum_id.
Later (when the interpreter closes)
the garbager processes gx_device_clist::writer.clip_path .
But in the test case it appears to be a pointer from global memory
to local memory, and its relocation appears wrong.
A crash happens while validating the heap after the relocation.
We're not sure why gx_device_clist::writer.clip_path
needs to be set between image plane data portions,
and why the garbager methods are coded to process it.
We guess all these manipulations are wrong,
and a right way should be to call cmd_check_clip_path
in clist_image_plane_data.
See also comment in cmd_check_clip_path :
"The clip path might have moved in memory".
We guess it assumes that the pointer is not relocated
when image_enum_id is zero and the ppointer is set.
We guess it should be regular assumption
for all cases, and the clist device garbager methods
must never process it.
This patch applies a minimal change to prevent the crash,
and does not close other suspections.
The change simply closes the image enumerator
when writing to it ends with an error.

DETAILS :
Bug 689249 "Major performance degradation rendering PDF",
The revision 7123 implements a conversion of imagemask
into a bigger image with a smoother pixel granularity.
Actually the conversion isn't useful for high resolution images
which map an image pixel into a small number of device pixels.
This patch implements such check and it apparently helps for pdfwrite.
Note it includes an arbitrary threshold,
which may need further adjustment.

Banding : Extend clist language with trapezoids, linear color trapezoids and linear color triangles (continued 8).
DETAILS :
Bug 689436 "pattern rendering regression with revision 8095".
Do not write tile phase to clist before trying to write the color.
If the latter fails, the phase may become wrong due to
overloading cmd_opv_set_tile_phase with tile phase and device halftone phase.
With the test case the old code, when writing a trapezoid to clist,
first writes halftone phase, then fails to write the pattern color
and falls back to gx_default_fill_trapezoid.
The latter writes strip_copy_rop with it own phases.
But the clist reader expects strip_copy_rop phase to be written
*after* the tile header, so the reader misses the phase sychronizm.
The fix simply delays writing the phase after the color is written.

Update pdfwrite to handle type 0 fonts with type 1 or type 2 descendant fonts (continued).
DETAILS:
Bug #689212 "irregular baselines - gs pdfwrite changes CFF to Type 3". There are no functional changes, the new code behaves the same as the old. The
temporary buffer allocated in pdf_text_process is used to hold the list of glyph
name indices, and the working buffer of indices for pdf_obtain_font_resource_unencoded,
rather than allocating new memory. This considerably simplifies the clean-up on
error in scan_cmap_text.
1. gdevpdtt.c In pdf_text_process, ensure that enough memory is available in the
temporary buffer. We need to promote character codes to glyph name indices, so
we need storage for as many glyph name indices as there were input character
codes. In addition, we need a temporary buffer of the same size for
pdf_obtain_font_resource_unencoded (maximum required) so we need to double this amount.
2. Update process_cmap_text to pass the buffer allocated in pdf_text_process, and
passed as an argument to process_cmap_text, to scan_cmap_text.
3. Alter the definition of scan_cmap_text to take the temporary buffer as an
argument. Modify the code in scan_cmap_text to use the temporary buffer rather
than allocating new space. Remove all the code for allocating and especially freeing
the temporary memory. Some corrections to indenting also performed here.

Update pdfwrite to handle type 0 fonts with type 1 or type 2 descendant fonts.
DETAILS
Bug #689212 "irregular baselines - gs pdfwrite changes CFF to Type 3"
There was previously no code in pdfwrite to handle type 0 fonts with type 1 descendant
fonts. This caused pdfwrite to 'fall back' to the default implementartion which converts
glyphs to a type 3 bitmap font.
This change is to enable scalable fonts to be embedded in the output. NB it is not
possible, in PDF, to construct a type 0 font with anything other than CIDFonts as
descendants, and we must therefore output one or more type 1 fonts to do the job.
1. (gdevpdtt.c) in scan_cmap_text add a case to handle a type 1 descendant font. The main
work is done in this routine; we create a list of glyph name indices representing
each of the input character codes and later we use pdf_obtain_font_resource_unencoded
and the TEXT_FROM_GLYPHS operation to mark the font usage, and create an 'encoded'
string for output.
If font->procs.next_char_glyph returns a glyph name index, then we simply add it to
our list, if it returns a character code (a CMap can map a character code in the type
0 font to a character code in a descendant font) then we use the descendant font
'procs.encode_char' to get a glyph.
Once we have a complete list of glyphs, we pass it to
pdf_obtain_font_resource_unencoded to add the glyphs to the encoding, and return a
string where the character codes match the newly created/modified encoding.
Finally we pass the encoded string and glyph list to process_text_modify_width, using
the descendant font.
A couple of minor points; its possible to change descendant fonts in the middle of a
string, and we need to cope with that, hence the copying of the last glyph in the list
when a font_change occurs. Its possible to return a different pdfont if we run out of
encoding positions in the current one, which can result in multiple type 1 fonts in
the output.
2. We need to use the function adjust_first_last_char, which was defined private in
gdevpdte.c, so this has been made public.
3. A prototype for adjust_first_last_char has been added to gdevpdtt.h
4. The function reserve_char_code_in_pdfont was written to handle single glyphs, it can
now be called with multiple glyphs. The loop for re-using positions in the encoding
with /.notdef codes didn't use the 'last_reserved_char' argument, which meant that it
kept returning the same position. To prevent this it now pays attention to the
'last_reserved_char' argument.
5. Finally, the routine pdf_make_text_glyphs_table_unencoded, which calls
reserve_char_code_in_pdfont also did not previously expect to be called with multiple
glyphs. The loop below do_unkown has been modified to use a local variable, instead of
pdfont->u.simple.last_reserved_char. THis means that, should an error occur, the value
of pdfont->u.simple.last_reserved_char will not be modified.

Fix (TT fonts) : Suppress loading trailing data after chosen cmap subtable.
DETAILS:
The current cmap selector/loader tries to load a subtable
for Microsoft platform && UCS2 encoding with anything
in trailer, although only MS+UCS2 subtable is used.
Thus, if the cmap table has several additional subtables
after MS+UCS2 subtable (e.g. multiple 16bit cmap subtable
for Shift-JIS/Big5/GB2312/Wansung/Johab, or very long
32bit subtable in format 8/10/12, or simple junk data),
cmap subtable loader tries to load MS+UCS2 subtable and
trailing garbage, and tries to define /cmaptab for
concatenated string of them. So, rangecheck or limitcheck
error can occur due to too-long string. Typical example
is found in bug 688337 which is caused by TrueType font
including cmap subtable in format 12.
If we restrict the scope to MS+UCS2 subtable, it must
not be greater than 0xFFFF bytes. Because cmap subtable
headers in format 0,2,4,6 define these tables length in
16bit. The cmap parser is fixed to check the subtable
header content and read exact length of chosen subtable,
to exclude trailing garbage.
In addition, /getinterval_from_stringarray has a bug
that appears when the end of requested string just fits
to the gap of member strings. The bug is fixed, too.
By this patch, bug 688337 is fixed.
DIFFERENCE:

after doing some settings (2 occurances in gxfill.c).

Fix (font rendering) : alloc_char_bits could fall into infinite loop.
DETAILS :
Bug 689036 "infinite loop in char cache logic".
The character cache algorithm assumes that a pointer to
any allocated cached_char instance appears somewhere in ccache.table .
However from the old experience we know that
this obvious invariant appears frequently broken due
to inaccurate manipulation with cache by clients.
For example, a client sometimes reserves and initializes
a cached_char instance and then fail due to another error
before storing the pointer to ccache.table.
In the old code a cycle in alloc_char_bits
strongly depends on this invariant,
and therefore it is potentially harmful.
In the past we have got a lot of bugs about it.
Now we restrict the cycle with the cache size.
Changed few function prototypes with returning error
if the invariant is broken.
Note that the graphics library interface changes,
so other interpreters must update the calls to
alloc_char_bits.

Fix (pdfwrite) : Properly handle FontMatrix of a Type 3 font.
DETAILS :
Bug 689267 "File converted to PDF displays badly in Acrobat".
Patch from SaGS. His explanation is quoted below.
Part #1: pdfwrite fixes (gdevpdti.c, gdevpdte.c, gdevpdtt.h, gdevpdtt.c :
- Generalize pdfwrite computations for glyph widths and placement,
which currently assume an [s 0 0 s tx ty]-type original (= ignoring
changes made by makefont & similar) FontMatrix, to work with an
arbitrary matrix.
- Fix: the "wy" operand of "d0"/"d1" in Type 3 charproc streams must
be zero. Note: other parts of the code already consider wy == 0,
and don't need to be changed.
- Remove font_orig_scale() and pdf_font3_scale(), which are not used
anymore. Their simple presence is a sign of the assumption that
font matrices are simple scalings.
- Minor: remove a dead variable ("int code = 0; ... return code;").
This variable is never changed, because there's another "int code"
inside the "for", but it is confusing and takes a lot of research
to figure out the behaviour is OK and no usefull error code is
lost (it's the 2nd time I stumble against this...)
Notes:
- All non-Adobe PDF viewers that I tested (Evince/ Fedora 7,
Foxit Reader 2.0/ Windows, Jaws PDF Editor 3.5/ Windows, and
Ghostscript -r8204) have problems with "weird" font matrices.
The bug in ghostscript is addressed below.
- I do have an alternate patch, which "normalises" the
FontMatrix, for better viewers compatibility . But this method
cannot work when fonts are not embedded: cannot "normalize"
something stored in an external file.
part #2: PDF interpreter fixes (pdf_font.ps, pdf_ops.ps) :
- Force the "wy" parameter of "d0", not only of "d1", in Type 3
charproc streams to 0. Comment changed to suggest this is an action
is expected to be done as part of enforcing the metrics stored in
the PDF (which always imply wy == 0), and not some strange
behaviour in Reader.
- A detail in PDF1.7 Ref 5.3.3 "Text Space Details" states that "wy"
(or "wx" in WMode 1) must be forced to 0 in PDF text space too, not
only in PDF glyph space. To implement this with non-[s 0 0 s tx ty]
font matrices, a different method is used: decode "show" strings
and extract glyph widths with "cshow", put these into an array,
then render the text with "x/yshow".
- since "wy/x" = 0 in glyph space, the code does not need to use
"idtransform", a "div" by "FontMatrix.xx" is sufficient;
- use a trick (see comment in code) when "FontMatrix.xx" = 0.
CIDFonts are not changed. Those with a "straight" matrix continue to
work, but there's no improvement if they have a weird "/FontMatrix".
I think this would require a radical change, and the result will be
much slower than it is now.
part #3: supplemental ps2write fixes (in opdfread.ps).
- opdfread.ps assumed the FontMatrix is a simple scaling by 0.001;
generalize the computations to work with an arbitrary matrix.
- Implement a detail of PDF1.7 Ref 5.3.3 "Text Space Details" (nuking
the "wy" in text space) if a non-[s 0 0 s tx ty] "/FontMatrix".
Similar to the change in the main PDF interpreter, but shorter
because opdfread.ps does not handle vertical writing or CID fonts.
Also "wy" in "d0"/"d1" is already 0 (see patch for pdfwrite), so
needs no adjustment.

Fix (TT font handling) : pdfwrite recieved meanless font names.
DETAILS :
Bug 688006 "Font names used with pdfwrite are strange with GS, OK with Adobe Distiller".
This is a continuation for the Revision 5862 change
made on Wed Apr 20 20:05:41 2005 UTC (2 years, 4 months ago) by ray.
Thanks to Edward for a code sample for accounting font style string.
1. (zbfont.c) When a Postscript file is generated with Adobe printer driver for Windows,
the old code (sinse Revision 5862) extracts OrigFintName
for building a meanful FontName.
This patch adds an use of OrigFontStyle as suggested by Edward,
so the FontName is created in the form "Arial,Bold".
2. (zfcid1.c) The old code sometimes dropped the good FontName in zbuildfont11
due to an extra call to get_font_name. Few lines above
the function build_gs_TrueType_font creates the good font name
during an indirect call to sub_font_params, so the call to
get_font_name is not necesary when OrigFontName presents.
However it is still necessary with regular FontType 11
because they have no FontName and sub_font_params
doesn't use CIDFontName.
3. (zfcid0.c) Applying the (2) change to FontType 9 as for symmetry.
We're tested it a few, but we have no untrivial examples
when a FontType 9 is embedded with OrigFontName.
Maybe (just guessing) ones could be obtained with installing
Adobe Type Library and printing with Adobe printer driver.
4. After doing all above, we unexpectedly detected a regression
with comparefiles/korea.ps : all Korean glyphs were replaced with
hollow boxes. Analyzing it we found that the document defines a
composite font with to CIDFontType 2 descendent,
which both appears to be same font. In same time,
the CMap supplies different CIDs for those 2
descendents for a half of code space. While the old code
used meanless unique font names, those 2 descendents
were converted to 2 PDF fonts. When we switched to the meanful name,
which of course is same for both descendents,
pdfwrite tries to merge the descendents.
However doing so it assumed same character mapping
for both descendents.
To fix this problem more changes are done to pdfwrite :
4.1. (gdevpdtf.h) The font descriptor of a type 0 font now stores font_index,
which is the index of its descendent font in the DescendentFonts array
of the source Type 0 font. This happens because in PDF type 0 fonts
always have a single descendent.
4.2. (gdevpdtf.c) Added an initialization for the new field.
4.2. (gdevpdtt.c, gdevpdtt.h) pdf_obtain_parent_type0_font_resource creates
unique type 0 fonts for each descendent in spite of same font name.
4.3 (gdevpdtc.c) pdf_obtain_parent_type0_font_resource needs
font index as a new argument.
4.4. (gdevpdtt.c) pdf_find_type0_font_resource also takes the new parameter.
With Korea.ps we create 2 font subsets where a single font
would be enough. An optimization may be done with a dynamic
check for encoding conflicts rather than creating another font
for each font index of the CMap. Delaying it for better times.

Fix (font rendering) : CIDFontType 9 missed PaintType.
DETAILS :
Bug 687970 "PaintType and StrokeWidth ignored with CIDFonts".
To make a decision about filling or stroking,
the old code uses PaintType of the current font,
However with CIDFont 9 it is a Type 1 subsidiary,
which has no PaintType.
The patch implements the 'or' logic for the PaintType of the root font
and the PaintType of the current font. We believe it should
correctly handle cases when PaintType 2 is set to
a root font or to its descendent. However we have not enough
practical test cases to test all varuiants.
Particularly, we would like to test a Type 0 font with
2 descendents, each of which is CIDFontType 9
and they have didfferent PaintType.
In such case this patch may need a further improvement.
The desision about filling or stroking a character is done in type1exec_bbox
and in nobbox_finish. The patch also passes a pointer to gs_text_enum_t instance
to type1exec_bbox to provide the data for the decision.

Fix (TT fonts) : Ignore invalid entries in loca table.
DETAILS :
Some problematic TrueType fonts have loca table that
the offset to a data in glyf table is larger than
the size of glyf table. In previous implementation
since trunk revision 5707 (ghostscript-8.57), when
such invalid entry is found, the font loading procedure
is immediately aborted and invalid font error is
returned. To continue the problematic TrueType object,
the invalid entries of loca tables now are ignored and
the font loading procedure is continued. If all entries
are invalid, the invalid font error is returned.
After the sorting of loca table entries by their values,
the invalid entries with too large offsets are collected
in the end of the sorted loca entries (psortary[]).
By this patch, the sorted loca entries are scanned from
from the end to the beginning, and the number of valid
entry is counted (num_valid_loca_elm). By this number,
the invalid loca entries are initialized to have null
glyph (the data size of glyph is set to 0).
By this patch, bug 689347 is fixed.

This set of changes is an example for users or Artifex customers
that want to intercept the color spaces and perform their own
color space conversion for the CIEBased or ICCBased color spaces,
converting all of these spaces to the PostScript color management
link space "CIE XYZ". There were changes needed to implement this
that transcended the original custom color callback scheme, but
the approach taken is intended to minimize changes to the color
space processing.
Artifex customer #330
DETAILS:
Rather than rely on the hack in gx_cie_to_xyz_alloc that sets the
pis->cie_render to ~0, we establish a separate boolean for this,
cie_to_xyz which indicates that we don't need a CRD (gxistate.h,
gsistate.c, gsciemap.c, gscie.c). Note that the gx_cie_to_xyz_alloc
function is also used in the lab_range function in gdevpdfk.c
to construct an L*a*b* ICC conversion space for the pdfwrite
device.
The 'pclient_color_space_data' is now handled in the ENUM and
RELOC procedures for the gs_color_space base structure shared
by all color spaces (gscspace.c). A side effect of this is that
the pclient_color_space_data structure MUST be allocated with
appropriate GC structure calls an with an appropriate GC type
of macro to identify the structure for the GC and establish
the ENUM and RELOC hooks. This was needed to allow a gs_imager_state
structure to be allocated for the CIE color spaces and to have
both structures to be 'known' to the GC logic.
The CIE_LOAD_CACHE_BODY macro and the gx_install_cie_abc function
are now exported in gscie.h rather than local to gscie.c so that
gsncdummy.c and other custom callback clients can use them.
Finally, the gsncdummy.c module now includes example handling
that allow the graphics library to convert colors to XYZ if
the original color space was one of the CIEBased or ICCBased
spaces. Since CIE XYZ to L*a*b* is a direct conversion, this
allows clients to work with device independent color.
The conversion from XYZ to ICC L*a*b* code exists in gdevpdfk.c
in the function xyz_to_lab() which might be useful enough to
export in the future. For the short term clients can 'clone'
this small function if needed into their own color callback
processing.
Note that -dUseCIEColor (or << /UseCIEColor true >> setpagedevice
PostScript sequence) will mean that all Device* colorspaces also
get mapped through the Default* colorspaces to XYZ (DeviceGray,
DeviceRGB and DeviceCMYK).

Fix for seg fault caused by undersized buffer as reported in bug report #687397
DETAILS:
Although the patch submitted by the reporter did appear to fix the problem,
it was more masking it than fixing it. While the analysis of the problem
being that ss->Items was too small was correct, the real cause was a rounding
problem in siscale.c/contrib_pixels(). The problem did not happen on my Mac,
but was reproduced up on peeves because of differnces in the way the two
systems perform rounding.

Fix (transparency in clist) : Write transparent paths and images to clist as high level objcts.
DETAILS :
Bug 689186 "PDF segfaults or exits with no output".
With the test case the old code creates a 2.5Gb clist file,
because it transformes transparent paths and images into rectangles.
The new code writes them as high level objects,
so that the clist file reduces to 477Mb.
1. (gdevp14.c) The old code appears to provide all necessary
methods for writing paths and images to clist as high level objects,
but doesn't call them. To activate them we simply replace default implementations
with forwarding methods in pdf14_clist_*_device.
2. (gdevp14.c) The old code sets the lop_pdf14 flag to
the clist reader's imager state. Particularly
it may be set when calling p14dev->pdf14_procs->put_image.
It causes gx_image_enum_begin to fail,
and the image silently dissappers from the output.
We fixed it with resetting the flag immediately before
calling p14dev->pdf14_procs->put_image.
A better way would be to synchronize log_op
in clist_create_compositor, but we don't like to
write it to all bands as other compoitor commands do.
3. (gdevp14.h, gdevp14.c) New fields inserted into pdf14_device_t
to provide a synchronization of encode_color, decode_color, get_color_mapping_procs,
get_color_comp_index with changing color_info. Debugged with pkmraw -r300 Bug688631.pdf .
Without them the 1bpc color conversions
were called from pdf14_cmap_cmyk_direct with an 8bpc color,
causing an almost white page instead blue axial and radial shadings.
4. (gdevm4.c) The old code defines a wrong color_info for mem_mapped4_device.
It defines 3 components instead the correct value 4 (3 colored and 1 gray).
5. (gdevp14.c) During the clist playback the new code does not change color_info
for the clist writer (p14dev->target->color_info). We marked this change
with the comment :
/* Disabled because *p14dev has no forwarding methods during the clist playback. */
We ise #if 0 because we're not sure why the old code does so.
We suspect it was done by a mistake and has no any effect.
#if 0 will keep it for a while.
More possible optimization :
1. Use pdf14_buf::bbox when back dropping a transparency buffer.
2. Use pdf14_buf::rect to restrict bands which set up the transparency compositor.
Now it is written to all bands.
3. Write text to clist as high level object.

Version 8.60 (2007-08-01)
This is a new stable release of the Ghostscript codebase. The most
significant change is the merge of drivers and other patches from
ESP Ghostscript. This version of Ghostscript work with CUPS and is
intended to be a replacement for the Easy Software fork going forward.
We extend a special thanks to Till Kamppeter and Mike Sweet for making
this happen.
In addition to CUPS support, the ESP merge includes a number of other
notable changes. The contrib directory of the GPL Ghostscript source
tree now includes a much larger complement of drivers. These are not
maintained by Artifex Software, Inc. and are not included in the
commercially licensed version, but are of great assistance maintaining
support for older printers in Linux distribution. The X11 device is now
modularized on Linux and Solaris systems when built with GNU ld, meaning
this device is compiled as a separate shared object which can be
optionally loaded at runtime, allowing the main binary to work on
systems without X client support installed.
This release also includes numerous important bug fixes over the
previous stable version, as well as improvements to performance, memory
footprint, shading and image handling. We recommend upgrading to all
users.

Incompatible changes
The default device on unix-oriented builds has temporarily switched to
the bbox device, and is not the x11 device as in the
past. The means that running gs from the commandline with no options
will no longer display a file. Specify -sDEVICE=x11alpha instead. The
change is a side effect of the X11 modularization patch, and will
be remedied in a future release.

Fix problem seen with stcolor device where the get_color_mapping_procs
device proc was NULL, causing SEGV. Bug #689371.
DETAILS:
The fix was local to gdevstc.c. The other modules were changed to
add protection in case other devices (such as all of the new devices
in contrib) don't manage to change the get_color_mapping_procs from
the usual default of NULL in the device structure. Rather than
dprintf or error messages that may be supressed with #if DEBUG.
I elected to use eprintf.
Note that the get_color_mapping_procs is usually set up by gdevdflt
gx_device_fill_in_procs, but there are several cases where we don't
know what to do, so we set the gx_error_get_color_mapping_procs.
The detection in gs_fillpage will usually result in a single error
message then we return gs_error_Fatal (-100).

Fix for gv hang, where an application sends (less than 1023 bytes)
PostScript and expects a response. AppleTalk PAP and some other
interactive viewer front ends may run into this. Bug #689237.
DETAILS:
The autosense is still sort of fragile in that we only process
PostScript immediately without waiting for the .peekstring of
1023 bytes to complete if it begins with "%!" or "%%". The
check for "%%" is needed for gv, conventionally "%!" is more
widely used. Note this really only affects applications using
gs as a process getting data from stdin and expecting immediate
action (response or other processing).
Also note that the %! or %% is only looked for as the first
two characters so that the presence of this in garbage before
an actual PDF won't cause confusion.

operator (Next display PostScript extension). Bug #592160.
DETAILS:
The bug report didn't include a test file, but reading the spec on
this operator found at:
http://objc.toodarkpark.net/AppKit/Functions/PSOperators.html
it seems that the number of components provided does not account
for the alpha channel. The relevant excerpt is:
Synopsis: pixelswide pixelshigh bits/sample matrix datasrc0 [...datasrcn] multiproc ncolors alphaimage -
Renders an image whose samples include an alpha component. This
operator is similar to the standard colorimage operator. However,
note the following:
* When supplying the data components, alpha is always given
last-either as the last data source (datasrcn) if the data
is given in separate vectors, or as the last element in a
set of interleaved data.
* The ncolors operand doesn't account for alpha -- the
value of ncolors is the number of color components only.
This final note is the justification for the patch.

Revert patch for rev 7904 which caused regressions (bug 689215).
The fix for this will be committed in a following patch that
fixes 688543 and 689364. Fixes bug 689215.
DETAILS:
The root of the problem is that the filled/stroked areas are
too large (from the fill_adjust value). Unfortunately changing
this to fix these problems causes MANY differences that need
to be examined. Initial examination shows many PROGRESSIONS,
i.e., we are closer to Adobe and from 200 files examined so
far, has not caused dropout (which is consistent with the
analysis).

Banding : Extend clist language with trapezoids, linear color trapezoids and linear color triangles (continued 6).
DETAILS :
This is an initial commit for decomposition of linear color triangles
that the target device can't handle while a clist playback.
The new code is not called with practical cases
because currently we have no devices
with an intrivial implementation of fill_linear_color_triangle.
We commit this code for future if someone will want
to implement that function in hardware with a smaller number of bits.
To force an execution of the new code
one can change this switch in gxclrast.c :
if 1 /* Disable to debug gx_fill_triangle_small. */
We debugged the new code with setting this switch to 0.
In this case the decomposition code starts, and calls
fill_linear_color_triangle again with same arguments
(except converting frac31 colors to 'float',
rather it doesn't miss precision with comparefiles).
This test works fine with comparefiles.
If the device method would request a further decomposition,
an earlier debugged code works, so we didn't test it now
(Testing it with available implementations would require an additional effort
for rejecting regular triangles by the target device).
For more details see comments in code.
Note the clist playback now calls gxshade6.c .

Banding : Exten\d clist language with trapezoids, linear color trapezoids and linear color triangles.
DETAILS :
This fixes the clist expansion problem for shadings.
1. New functions clist_fill_linear_color_trapezoid, clist_fill_linear_color_triangle
provide the writing of shading parts into clist
without a further decomposition into rectangles.
2. gxclrast.c is enhanced with reading the data from 1.
3. gxfill.c needs a special interaction with the clipper device
for passing the clipping path as a high level object.
The new request pattern_manage__handles_clip_path
checks whether the target device can handle a clipping path.
The clist writer can, so the graphics library first sends the
clipping path, and then decomposes the shading into
trapezoids without installing a clipper device.
Doing so because clipper device can't handle trapezoids.
See comments in gxclpath.c, gxfill.c .
4. The clist reader installs a clipper device when processes
trapezoids and linear color triangles.
The new flag clipper_dev_open controls that.
5. A new flag gx_device_clist_writer_s::cropping_by_path
controls an additional cropping of shading components,
which fall outside the shading path's bands.
See comment in gxclpath.c .
6. R_fill_rect_with_const_color is rewritten with linear color functions,
because the old implementation creates a rectangle, which is not clipped with
4,5. It gives an invisible slowdown for unbanded rasters.
There are few things, which need further improvements :
1. A better compression for frac31 values in clist.
Such values usually have many zeros in ending bits.
2. Crop bands with ybot, ytop, fa->ystart, fa->yend in
clist_write_fill_trapezoid.
3. The clist reader must handle cases when linear color functions return 0.
It must perform a decomposition of areas with calling
appropriate parts of gxshade6.c . The current code returns error,
which does not happen in practice.

Fix : Restoring high level objects in clist.
DETAILS :
This patch is a part of the clist expansion problem.
With Henry's test foo4.ps it reduces the clist size in 10+ times.
The clist expansion problem appears to be caused by an old unintentional
change, which was done 3 years ago within the psdcmyk project.
The revision 5056 effectively disabled a big part of the clist language:
all high level objects (text, images, paths) were written to clist
as lots of rectangles. Undoing it now because it is incorrect.
Note that this patch doesn't undo other parts of 5056 change.
With enabling high level objects the psdcmyk device becomes broken.
At least it has problems with text when rendering foo4.ps .
We'll open a separate bug about that.
Rather this fix is a progression, it causes some regressions with
band devices due to other unknown problems.
There are single pixel differences with comparefiles,
which are not visible to users, but they are important
for regression testing. Since the clist size
is a highly important problem now, we commit this fix,
and open a new bug about raster differences.

Compare the type of the object cached in the font descriptot with the expected
type and ignore the cache when the types mismatch. The same descriptor can
refer to Font and CIDFont resources if they happen to have the same name and
are not embedded. Bug 689301, customer 870.
DETAILS:
tx_pdf 12.0.112.500 created quite strange PDF file. The file refers to
Palatino font and Palatino CIDFont through the same font descriptor.
Both the font and CIDFont versions are not embedded. There's no rule in PDF
against merging equal objects from unrelated contexts.
Old code cached the font or CIDFont file in the font descriptor.
Re-using the font descriptor for a different type of the object caused the
wrong object to be retrieved from the cache. In turn, this causes /undefined
error later on.
The patch compares the type of the cached object with the expected type
and ignores the cache when the types mismatch. In our case this results in
an attempt to find Palatino CIDFont resource. Since this resource is not
available, the CMap name is used as a default CIDFont resource name for
the given CMap. In this case, /Adobe-Japan1 /CIDFont resource is searched.
When this resource is available, the file finishes normally. Otherwise the
file fails with /undefinedresource in findresource.

tagged RGB where presumably text objects would map. This is a reasonable
temporary approach since copy_mono is used for bitmapped text.
Also remove the "SKIP_OUTPUT" compile time #define and add "output_is_nul"
detection of the OutputFile name being nul: or /dev/null to make it easier
to go back and forth between timing runs (to /dev/null) and runs where we
want to look at the output.

Fix an out of bounds buffer write in the wts_load_halftone logic and fine
tune the wts_resolve_one color conversion cache hashing for 4K (the default).
Bug 689255 for customer 951.
DETAILS:
Besides fixing the out of bounds logic, I added a 'bufsize' parameter to the
gs_wts_from_buf logic so that we can detect OOB conditions. Note that the
1+hdr_size+cell_size in gx_ht_read_component_wts is retained by this patch
even though it looks bogus (we want to commit the fix so we can send to a
customer, and will look at this later).
In refining the cache stats in the wtsimdi device, the 'fill_empty' case
and the 'collision' case were split to make sure that the hash is decent,
but even 1M cache hits (on ACDsee.prn) only save about 1.5 seconds (out
of 9 seconds). The hash algorithm for smaller collision rates won't really
matter much.

Fix : Expanding gxcldev.h macros, part 2.
DETAILS :
This change is algorithmically equivalent.
The purpose is to eliminate gxcldev.h macros
to simplify the debugging of the clist writer methods.
This 2nd step replaces HANDLE_RECT_UNLESS
with macros that don't include goto or return statements.
Besides that, the pattern :
if (code < 0) {
band_code = code;
goto error_in_rect; /* ERROR_RECT(code); */
}
is replaced with the smaller one :
if (code < 0 && SET_BAND_CODE(code))
goto error_in_rect;
for a better readability.
Some compilers may claim unreferenced label error_in_rect.
To be fixed in the next step.

Add logic for a configurable color lookup cache to the wts* devices.
Currently set to 4K (4096 entries). Testing indicates this is a
reasonable value, adequate for all synthetic/graphics arts pages
and adequate for photos/scanned images.
DETAILS:
The hash function is rather arbitrary, but some experimentation with
more sophisticated hashing doesn't really show much difference since
the color lookup isn't such a high CPU load even on the performance
files which are entirely images. A 4K CLUT achieves 1.4M hits and
even a 64K CLUT size only gets 1.6M hits (out of ~6M pixels) .

Fix (PS interpreter) : "undef" data change was not properly saved.
DETAILS :
Bug 689284 "Abnormal dependence of 'known' on name hash indices".
The "undef" algorithm has an "optimization" branch for packed keys,
which replaces "deleted" elements with "empty" (i.e. unused).
However this data change was not tracked for "restore".
In some rare cases it causes a wrong result for "known", "get", "bind"
and others. Interesting that "dictforall" doesn't miss such keys
when "known" does, but it could enumerate same key several times
with older values.
The bug persists since the repository was created in March 2000.
This change simply saves the changed data for restore.

DETAILS :
This change is algorithmically equivalent.
The purpose is to improve the debugging technology.
It allows to trace through the packed search code

We define a new variable 'wrap'
for reducing 3 macros to a single template.
We believe it shouldn't cause a sensible slowdown.
An alternative is 2 (nested) templates and no new variables.
We noticed that the missing key case is not optimized well.
When the key is missing, the algorithm scans the
left part of the array 2 times. One time should be enough.
It should be optimized in a separate patch.

Fixes for ulong overflow in memory device buffer sizing that caused
problems with very large (>4Gb on 32-bit machines) page buffer sizes
not invoking clist mode. Also the internal 'mask' image allocation
in ImageType3 would silently wrap around, causing SEGV crashes.
Lastly, the tiff*nc devices are fixed so that they never write to
file when the file will exceed 2Gb (max signed int) since the device
uses 'ftell' to calculate offsets in the file. This last case could
be fixed to use 64 bit file I/O or at least to keep an internal
offset so that multipage tiffs could be > 2Gb as long as each page
was less than 2Gb. Other TIFF devices that compress were not changed
since the probability of overflow is less and we don't want to be
overly agressive about throwing a 'rangecheck' on the basis of the
uncompressed size.
Bugs 688808, 688815 and 689080 for customer 190 (and others).
DETAILS:
The buf_device/bitmap sizing functions now return a success code,
setting the size using a pointer passed as a parameter. A bitmap
that overflows max_ulong now throws gs_error_VMerror so that the
caller can take appropriate recovery action (such as gdevprn using
a clist instead of a page buffer).
The ImageType 3 mask probably needs an internal clist method (such
as was done for the pattern accumulator) to avoid this overflow.
As mentioned above, the TIFF devices, particularly the '*nc' type
(not compressed) could benefit from using 64-bit file I/O calls
for those that want to fill up large hard drives quickly.

This is a fix for regression bug report 689263.
DETAILS:
Some versions of PhotoShop generate documents that place an extra value on the operand stack and tintTransform replaces it - see bug 549307 for details. Also see the test case of bug 689263. Since GS invokes setcolor as a side-effect of setcolorspace, we must prevent Adobe's hack from pop'ing an extra (significant) item from the operand stack when setcolor is invoked from a setcolorspace context.
The previous patch for bug report 688584, which was committed before I was done with it, was too broad and was undoing Adobe's hack whenever setcolor was invoked (from setcolorspace or otherwise). This change also undoes the previous patch, which was the cause of the error:

Fix (shadings) : Optimize path manipulations for shading fill (continued 2).
DETAILS :
This is the 2nd step for the elimination of gs_shading_fill_path.
It excludes that function from high level devices.
After the last patch, ps2write is only device that calls gs_shading_fill_path
while converting a shading into an image.
This patch replaces that call with a call to gs_shading_do_fill_rectangle.
This patch also fixes the revision 8017 regression
with the change to gdevpdfi.c .
Minor changes :
1. lcvd_fill_rectangle_shifted_from_mdev appears to be same as lcvd_fill_rectangle_shifted.
Removing the 1st one.
2. path_scale appears almost same as gx_path_scale_exp2_shared.
Removing the 1st one.
3. In gdevpdfd.c, when the scale isn't dividing by 4,
the old code chooses a smaller scale by X.
The new code dies by Y for a better view.
It may cause minor differences in raster.
4. We're not sure why lcvd_get_clipping_box_from_target was used sometimes.
It looks incorrect. Replaced with lcvd_get_clipping_box_shifted_from_mdev.
5. gx_cpath_scale_exp2_shared didn't scale list->xmin, list->xmax.
6. gx_cpath_copy is defined and not used.
Saving it from a dead branch, because it may be useful in future.

Fix (shadings) : Optimize path manipulations for shading fill.
DETAILS :
This partially improves performance for the test case of
the bug 689189 "PDF fails with /unregistered in --shfill--".
While filling a shading, the old code
converts the clipping path into a path, then
converts it to a clipping path for intersecting it
with the filling path and with the shading BBox.
These manipulations are neccessary due to the
interface restrictions for gs_shading_fill_path,
which doesn't pass a clipping path.
It causes (1) a bad performance and (2)
a wrong fill adjustment, because the conversion
of a path to a clipping path and back to path
is not identity due to fill adjustment.
The new code is a 1st step for the elimination of gs_shading_fill_path.
This patch excludes this function for raster devices.
Excluding it for higth level devices will be a next step.
The new code moves path manipulation outside the
shading color painting. Now all 3 pathes
(the filling path, the clipping patrh, and the shading BBox)
are processed in gxfill.c . The painting
is done with gs_shading_do_fill_rectangle,
which does not manipulate with pathes.
The patch modifies gx_image_fill_masked_end
to comply with the new inplementation of
gs_shading_do_fill_rectangle when a mask
is converted into a clipping path.
Another optimization avoids the generation
of a filling path for 'shfill'.
Accorgong to PLRM, shfill deals with clipping path,
but it was converted into a path due to
internal Ghostscript constraint for the device interface.
When the device implements fill_path with
the default method gx_default_fill_path,
the conversion to a path is not necessary.
To make use of this fact for optimization, the graphics library
needs to know, whether the output device uses the default
function gx_default_fill_path. This patch introduces a new response
for pattern_manage, which is named 'pattern_manage__shfill_doesnt_need_path'.
The device must respond with 1 if it does not need a path.
The patch provides implementations for raster devices and
for forwarding devices. If some device provides an instandard
fill_path method, the optimization won't work for it
(i.e. it will work as before - will recieve a path for shfill)
unless it provides a proper response to pattern_manage__shfill_doesnt_need_path .
A minor change to gdevpdfb.c fixes a paranoid compiler warning
about a possible use of unubnitialized data.

Change built-in compression threshold for memory based clist to
improve performance.
DETAILS:
The (example) compression threshold used with BAND_LIST_STORAGE=memory
is much to small to represent current embedded devices (where we expect
to not have a disk). On one customer's (#951) performance test files,
this change shows an overall 9.2% performance increase, ranging as high
as 20% on one file. For this test suite, even 22M is enough to avoid
compression.
The intent is that the compression threshold be a dynamic value that
uses current "real time" memory available in the printer rather than
some arbitrary fixed value. If the clist writer logic waits for all
potential renderer/reader tasks to stop and free their clist RAM,
then the need to compress becomes even less likely.

In this case the shading rasterization is replaced with
painting a pure color.
1. The new function R_fill_rect_with_const_color is the main worker.
2. The old patch_color_to_device_color function is renamed into
patch_color_to_device_color_inline.

DETAILS :
Bug 689211 "PDF interpreter creates redunDan Cobyt shadings".
This partially improves performance for the test case of
the bug 689189 "PDF fails with /unregistered in --shfill--".
The test case defines 79 shadings. While interpreting it
the old code calls zbuildshading2 9600+ times.
1. Improved resolveshading with reusing old shadings (pdf_draw.ps).
2. Improved 'sh' with reusing old shading dictionaries (pdf_draw.ps).
3. Renamed gx_currentciecaches with gx_unshare_cie_caches,
because the old name does not comply to the function body.
4. Defined a new function gx_currentciecaches.
5. The macro CIE_CHECK_RENDERING is replaced with a new function
gx_cie_check_rendering_inline. The new code also checks
the consistency of cie_joint_caches with the color space
by checking the id, and requests refilling the cache if necessary.
Note it can cause the PS interpreter callout with EncodeLMN, etc.
6. IMPORTANT: The new field gs_shading_params_t::cie_joint_caches
saves the pointer to gs_state::cie_joint_caches.
It is used in .shfill - see zshade.c .
Debugged with Bug688631.pdf .
7. NOTE: *gs_shading_params_t::cie_joint_caches may be left unreleased
when the shading releases. The garbager will release it.
This happens with PS interpreter only.
8. NOTE: We do not make cie_joint_caches be a property of color space,
rather it would look natural. The reason is that this large structure
is needed to save with shadings only. Saving it for any color space
would spend too big RAM.
9. NOTE: Due to historic reason gs_setcolorspace leaves cie_joint_caches
unchanged. It may cause problems when gx_color_space_needs_cie_caches
is true. Postscript interpreter has a special workaround for it in
gs/lib/gs_cspace.ps . Other interpreters may need an additional support
when they use CIE spaces directly or indirectly.
Likely this feature is not properly documented.
10. NOTE: The change to pdf_draw.ps cases an additional RAM expence for
PDF interpretation. It is caused by saving all built shadings
until the document finishes. It includes the expence for extra copies of
cie_joint_caches. The new procedure .free_page_resources frees
shadings from page Resources after page finishes.
However this patch does not implement that for
other local resources, such as form Resources, etc.
It may need a further improvement.

Change the .ppm output from the wtsimdi device to write a P6 with
a max value of 255 (instead of 1). Some viewers assume a max value
of 255, so the previous output looked all black. A max value of 255
works with all known viewers.

Back out the changes associated with 7715 and 7773. This fix is
probably wrong, it only masks an underlying problem by disabling high
level images and it slows down many jobs. I believe the problem was
misunderstood from the outset but I don't clearly understand the svn
change log, it reads:
Fix for banding of some images not matching non-banding output.
Added check for an invariant that the translation matches in the
two matrixes used in rendering. In this case the non-high level image
path is taken. A better solution would be to a single matrix, as this will
increase the display list size for some files.
It is not clear what "single matrix" means. There is one ctm
associated with the image and one associated with the graphics state,
both must be used by either the high level image code or the default
image machinery. The change checked that graphics (imager) state ctm
translation components matched the translation components that map
image space to device space.

Fix (shadings) : Shorten a radial shading when it is larger than paint area.
DETAILS :
This partially improves performance for the test case of
the bug 689189 "PDF fails with /unregistered in --shfill--".
The test case includes multiple radial shadings,
which are 100+ times larger than the path bbox.
This patch replaces such shadings with a smaller shading,
which paints the bbox with same color
(a minor color difference is possible due to rounding errors).
See comment in code.
