Ghostscript is een interpreter voor de PostScript page description language die door printers wordt gebruikt. Hiermee worden de grafische commando's, bedoeld voor de printer, omgezet naar een bitmap-afbeelding. Deze afbeelding kan vervolgens naar bijvoorbeeld het beeldscherm gestuurd worden. De ontwikkelaars hebben versie 8.64 van Ghostscript uitgebracht en voorzien van de volgende aankondiging:
Artifex Software is happy to announce a new stable release of GPL Ghostscript and GhostPDL. This is the fifth release in the stable Ghostscript 8.6x series. The corresponding GhostPDL release is 1.54. Approximately 100 bugs have been fixed since the 8.63 release.
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.
Also improved is handling of CJK text, especially in vertical writing modes, memory footprint processing some files at high resolution and support for using the system's default paper size on unix.
The interpreter's handling of color spaces has been moved from PostScript code to C.
A number of the included printer drivers and cups wrappers have been updated to support a PDF-based workflow. Also fixed are several long-standing bugs in the pcl drivers with respect to duplex, resolution and paper tray selection.
Thanks to everyone whose hard work made this release possible!
