Ghostscript is a leading independent interpreter software with the most comprehensive set of page description languages (PDL’s) on the market today.
Conversion capabilities cover PDF, PostScript, PCL and XPS languages. It has been under active development for over 20 years, and offers an extremely versatile feature set which can be deployed across a wide range of platforms, modules, end uses (embedding in hardware, as an engine in document management systems, providing cloud solution integration and as an engine in leading PDF generators and tools).
With the release of version 9.22, Ghostscript becomes the first PDF interpreter to support the reading and rendering of documents in the new PDF 2.0 specifications. Updates to the Ghostscript code base include UTF-8 improvements, Page-level Output Intents, Black point compensation, and Halftone origin.
Suffice to say, in the hands of a skilled developer Ghostscript is a veritable Swiss army knife. Having been battle-tested in nearly all possible usage and platform implementations, it’s a solution you can rely on.
Ghostscript provides the following specific technologies:
- Ghostscript – The original Ghostscript product is an interpreter/renderer for PostScript and normalizing PDF files. It delivers a full array of format outputs (PDF, PDFA, PostScript, PCL, XPS, Raster files, Vector objects, Unicode/ASCII text and printer pipeline).
- GhostPCL – Interpreter/renderer for PCL files, delivering the full range of format outputs.
- GhostXPS – Interpreter/renderer for XPS files, delivering the full range of format outputs.
