Hi All, I've built an OS/2 binary of Ghosctscript 8.63 and it's available from my site at http://os2ports.smedley.info This has been tested both with CUPS and with GSView. Cheers, Paul. Source: Paul Smedley -------- Original Message -------- Subject: [gs-devel] GPL Ghostcript 8.63 and GhostPDL 1.53 released Date: Fri, 1 Aug 2008 13:45:13 -0700 From: Ralph Giles Artifex Software, Inc. is pleased to announce the release of GPL Ghostscript 8.63. 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 ghostpdl release features improved XPS to PDF conversion as well as a number of other bug fixes. 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. Incompatible changes in this release: 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. Thanks to everyone whose hard work made this release possible! -r Ralph Giles Ghostscript.com _______________________________________________ gs-devel mailing list This e-mail address is being protected from spam bots, you need JavaScript enabled to view it http://www.ghostscript.com/mailman/listinfo/gs-devel Please let Paul know if you find this software useful.
