Of particular note are robustness and performance improvements with large files, invalid PDF, and font handling. A number of the included printer drivers and cups wrappers have been updated to support a PDF-based workflow. Ghostscript can also serve as the ghostscrript for PDF to raster image png, tiff, jpeg, etc.
The Garamond font has additionally been improved upon. The input document is first parsed, and then each page is split into n bands which are rendered concurrently.
The interpreter's handling of color spaces has been moved vsrsion PostScript code to C. Approximately bugs have been fixed since the 8. The halftone tile cache sizes and cache effectiveness were improved to help the performance when tiling with large cells or threshold arrays. Views Read Edit View history. This is a new stable release of the Ghostscript codebase.
This release also includes numerous important bug fixes over the previous stable version, as well as improvements to performance, memory footprint, shading and image handling. The values in the threshold array were inverted, so the verrsion of 'light' colors was limited and using it generally vedsion prints that were too dark. Its main purposes are the rasterization or rendering of such page description language  files, for the display or printing of document pages, and the conversion between PostScript and PDF files.
This document is a record of changes in Ghostscript releases numbered 8. And there are numerous robustness, correctness and performance improvements. These are not maintained by Artifex Software, Inc.

As of this release all platforms match the recommended implementation limits in the specification. Previously everything was in src. A number of the included printer drivers and cups wrappers have been updated to support a PDF-based workflow. This version is the next in our line of scheduled semi-annual releases. This is the fifth scheduled release in the stable Ghostscript 8.
Interpolation and color management are both expensive operations, so this affects performance with large images.
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. PostScript and PDF interpreter.
Later, Deutsch formed Aladdin Enterprises to dual-license Ghostscript also under a proprietary license with an own development fork: In other projects Wikimedia Commons. Interpreter source files are now in psi and the graphics library and output devices are now in base. A new cdnj device was added to support the HP DesignJet Ghostscript licensing changed to AGPL". Support for using FreeType as a type rasterizer has been greatly improved.
This is the first release in a new stable series of Ghostscript releases.
Detailed History of Ghostscript versions 8.n
As it takes the form of ghostsfript language interpreter, Ghostscript can also be used as a general purpose programming environment. Support for tiff file output is now provided using the libtiff implementation rather than our more limited native code as in previous releases. Incompatible changes In this release the C source files have been split into two new directories.
There are two new devices in this release, both experimental. Of particular note in this release are improvements to overprint and spot color support in documents with transparency, improvements to PDF and PS output, proper handling of PDF-specific text rendering modes and support for reading AES-encrypted PDF documents.
Incompatible changes The default device on unix-oriented builds verion temporarily switched to the bbox device in the 8.
