[Gs-dgs-devel] Using GhostScript to transform PostScript into programming objects?

[Alex Cherepanov]

Dear Mr. Bleisteiner,

Ghostscript can be used to retrieve high level object from the
Postscript file. In fact it is already used this way by PDF
driver and preserves most of the high level information in
 the PDF file.

We don't have other high level drivers. So the interface between
Ghostscript and high level driver is still under development.

Medium level driver converts PostScript to path, fill, and
sampled image operations. pswrite is a good example of this level.
The interface on this level is quite stable.

Low level driver reduces the PostScript graphic to filled
rectangles in device coordinate system. Most drivers for real
raster printers are low level drivers.

Ghostsctipt is mostly free software. Everybody can develop any
programs based on GS technology and distribute them for free
or use in-house for any purpose. Only commercial redistribution
of GS technology requires the license from Artifex Software, Inc.
Older versions of GS are re-released under GPL.

Commercial version of Ghostscript comes with technical support
from Artifex engineers. Unlike Adobe or 5D our fees are moderate
and licensing terms are flexible. Please consider some kind of
support contract if you are going to develop a high level driver.
