Red Hat Bugzilla – Bug 457684
8.63 was released
Last modified: 2008-11-12 04:45:16 EST
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.
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.
ghostscript-8.63-1.fc9 has been submitted as an update for Fedora 9
ghostscript-8.63-1.fc9 has been pushed to the Fedora 9 testing repository. If problems still persist, please make note of it in this bug report.
If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update ghostscript'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F9/FEDORA-2008-7035
is it ready for Fedora 9 *updates* ?
ghostscript-fonts and urw-fonts packages can be deleted because they are the *same* , and they are already included into ghostscript since 8.62 version(in Resource/Font/ directory)
ghostscript-8.63-1.fc9 has been pushed to the Fedora 9 stable repository. If problems still persist, please make note of it in this bug report.
Reopening to investigate comment #5.

And *.afm *.pfb *.pfm 'sources', aka urw-fonts package, here: http://svn.ghostscript.com/ghostscript/trunk/urw-fonts/
