Version 9.01 of Ghostscript


Release Notes: A new, robust CFF parser was implemented in C, replacing the previous PostScript one. The tiffscaled device was added, which renders internally as tiffgray, but then downsamples by an integer scale factor and error diffuses to 1bpp output. DSC compatible output was added to ps2write. A number of performance, memory use, and stability improvements with the new features introduced in 9.00 were made, plus the usual bug fixes.

Other releases

Release Notes: A improved "eps2write" device was added to replace the deprecated "epswrite" device. The "pdfwrite" device now uses the same color management engine as Ghostscript rendering devices, by default LCMS2. A new "pwgraster" output device was added. The CUPS device now has improved support for PPD-less printing. Memory usage when processing PDF files that use transparency was reduced. Various other minor improvements and bugfixes were made.

      Release Notes: This release changes to the AGPL, improves thread safety, produces "Direct Web View" PDFs directly, extends the Font API to support PCL/PXL and XPS as well as Postscript/PDF, adds new options adding flexibility to the color management workflow, and adds a BigTIFF output option.

      Release Notes: PDF/A-2 support was added to the pdfwrite output device. Suport was added to pdfwrite to be run in "server mode" and for the "%d" format in the OutputFile switch, for writing individual files. The output created by ps2write was modified to support the deficiencies in a range of recent PostScript devices. Support for large numbers of separations was improved for the tiffsep* devices, resolving "unencodable pixels" errors. The devices tiffsep, psdcmyk, and psdrgb gained "downscaler" support. Many other bugfixes, compatibility changes, and incremental improvements were made.

      Release Notes: The PDF interpreter now can make use of the DroidSansFallback TrueType font to automatically substitute for missing CIDFonts. Support for "unmanaged color transformations" (with the command line option "-dUseFastColor") for source DeviceXXX colors was added. A simple ink-coverage device is now included. The TIFF, JPEG, and PNG output devices now support embedding of the device ICC profile. Optimized OpenJPEG sources (for JPEG2000 decoding) are now included in the distribution. jbig2dec gained simple halftone region support. The ps2write device gained output quality and stability improvements.
