GPL Ghostscript is an open-source PostScript interpreter that includes integrated support for the CUPS printing system in Mac OS X. It is the replacement for ESP Ghostscript.
What's new in GPL Ghostscript
Support for tiff file output is now provided using the libtiff implementation rather than our more limited native code as in previous releases. There is also a new 'tiffsep1' output device which produces halftoned separations at 1 bit-per-pixel, in contrast to the 'tiffsep' device which produces 8 bit-per-pixel plates.
Support for using FreeType as a type rasterizer has been greatly improved. We do not recommend its use as of this release, but it is much more functional than previously and our intent is that it will become the default in a future release.
The graphics library has been updated to provide more accurate scan conversion of vector art including fixes to dash behavior, transparent stroked paths, thick stroked paths, radial shadings, xps cap handling, "pie" joins, degenerate beziers, improved handling of dropouts in thin strokes and better thin axis-aligned strokes.
