v9.27 [Sep 26, 2016]
The usual round of bug fixes, compatibility changes, and incremental improvements.
v9.19 [Sep 2, 2013]
- Background printing (BGPrint) is a new feature allowing an accumulated page clist to be rendered by one or more rendering threads whilst the interpreter (in the "main" thread) continues to accumulate the subsequent page's clist. For certain classes of file this can result in a useful performance increase.
- GrayDetection allows suitably written devices to detect "color" input in near neutral tones (i.e. near monochrome) and to convert "on-the-fly" to pure grayscale, whilst retaining the ability to print full color on demand. This is primarily aimed at workflows where saving ink (especially color inks) is required.
- LittleCMS2 and libpng have both been updated to the latest versions.
- Support has been added to build the Ghostscript DLL for WinRT for x86, x64 and ARM (Requires MS Visual Studio 2012 Pro).
- Processing of Windows command line arguments into UTF8 (as presaged a few releases ago) has been enhanced and enabled by default.
- The URW Postscript font set has been updated to the latest version, fixing many compatibility problems with the Adobe fonts.
- Plus the usual round of bug fixes, compatibility changes, and incremental improvements.
v9.09 [Sep 18, 2010]
This is the third release in the stable 9.x series.
This a an "out of order" release, primarily to ensure the GPL Ghostscript release remains in version "lock-step" with the Artifex commercial release.
Highlights in this release include:
For monochrome devices, there is a new halftone technique for sampled image data. The existing technique is very efficient (and is is still used) for large areas of color, such as an area fill, but encountered performance problems dealing with sampled image data where a given colour value only covered a few pixels at a time. The new approach applies the halftone threshold array directly to the image samples.
Further performance, memory use, and stability improvements with the new features introduced in 9.00, as well as Unix/Linux build fixes, plus the usual assorted bug fixes.
