Overview of Ghostscript
This document is a roadmap to the Ghostscript documentation.
After looking through it, if you want to install Ghostscript and not only
use it, we recommend you read how to install
Ghostscript, and how to compile Ghostscript from
source code (which is necessary before installing it on Unix and VMS
systems).
Table of contents
Document roadmap by theme
What should I read if I'm a new user?
- how to use Ghostscript. This includes both
a quickstart introduction to the commandline version and more extensive
reference material.
- detailed information about specific
devices that Ghostscript can use for output
- information about reporting problems--but
remember that Ghostscript comes with NO WARRANTY and NO
SUPPORT
- more detailed information about how to use Ghostscript under
Unix with lpr as a filter
for printing
AFPL Ghostscript and GPL Ghostscript
AFPL Ghostscript and GPL Ghostscript are different releases.
If you have AFPL Ghostscript, not the GPL Ghostscript releases, you should
read (or at least skim through):
If you run into any questions, or if you are going to be using Ghostscript
extensively, you should at least skim, and probably eventually read:
Before building Ghostscript
If you are going to compile Ghostscript from source, rather than just use an executable
you got from somewhere, you may want to read:
What should I read if I'm not a new user?
If you have already used Ghostscript, when you receive a new release you
should begin by reading this file, then
- News.htm, for incompatible changes and new
features in the current release;
- if you wish, Changes.htm, for a detailed list
of changes in the current release;
- if you wish, History#.htm (currently History8.htm), for changes in other releases.
What if I'm a developer?
If you are going to do any development on or with Ghostscript at all, you
should at least look at
If you are going to write a new driver for Ghostscript, you should read
If you are considering distributing Ghostscript (either AFPL or GPL
versions) in conjunction with a commercial product, you should read the
license carefully, and you should also read
If you intend to use Ghostscript in the form of a dynamic link library
(DLL) under OS/2 or Microsoft Windows or in the form of shared object
under Linux, read
If you want to use Ghostscript as part of another program--as a callable
PostScript language interpreter--and not as a DLL or as a self-contained
executable application, you should begin by reading
- the source file imain.h, the documented
API for Ghostscript not as a DLL
or if you are going to use only the Ghostscript graphics library,
What if I'm writing documentation?
If you are editing or adding to Ghostscript's existing documentation in
HTML format, or writing a new document, you should read
Presence on the World Wide Web
Ghostscript's home page
Ghostscript has a home page on the World Wide Web with helpful information
such as the FAQ (Frequently Asked Questions) and a list of known problems
and workarounds for the current AFPL Ghostscript release (in the
"Obtaining" file for that release):
http://www.cs.wisc.edu/~ghost/
More material about Ghostscript can be found at
http://www.ghostscript.com/
Adobe PostScript, Encapsulated
PostScript, and PDF reference documentation
Adobe makes a wealth of technical documentation available over the Web,
including the
PostScript Language Reference Manual (Third Edition); the
Encapsulated PostScript (EPS) Format Specification version 3, including
Encapsulated PostScript Interchange (EPSI)
format; the
PDF Reference manuals.
The Acrobat SDK contains
pdfmark and Acrobat Distiller parameters documentation.
Some of these documents
are also available at Adobe's ftp
site, but not necessarily under the same filenames.
Other material on the WWW
Much other material about Ghostscript is available on the World Wide Web,
both as web pages and as archived Usenet and mailing list discussions. Use
the well-known search engines to find such material.
There is a translation of the Ghostscript 'man' pages into Czech at:
http://www.volny.cz/rebus/ghostscript/
