Introducing Dr. Michael Vrhel

November 17, 2008. Artifex Software Inc. is pleased to announce that Michael J. Vrhel, Ph.D. has joined the staff at Artifex at the position of Senior Color Scientist. Dr. Vrhel has co-written "Fundamentals of Digital Imaging" recently published by the Cambridge University Press. Dr. Vrhel has Ph.D., MS, and BS degrees in Electrical and Computer Engineering from North Carolina State University and Michigan Technological University, Houghton. Dr. Vrhel has over 15 years experience in color science and software architecture with Pagemark, TAK Imaging, ColorSavvy, and Eastman Kodak. According to Miles Jones, president of Artifex "We are extremely pleased to have Michael join our team. With Michael's tremendous skills in color science and software architecture, we expect that Ghostscript's color-handling will be second to none."

Ghostscript Technology Developments
"Rendering on Multiple CPU Cores in Parallel"

This is the fourth scheduled release in the stable Ghostscript 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 -dNumRendering Threads=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 he custom color management callbacks for interpolated images. Interpolation and color management are 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. 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.
