Overview of Ghostscript

If this is your first contact with Ghostscript, before continuing here you should read the documentation for new users, where you'll find

The rest of 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).

Document roadmap by theme

What should I read if I'm a new user?

A new user of Ghostscript should begin by reading the material specifically for new users, then as many of these documents as seem useful:

Aladdin Ghostscript and GNU Ghostscript

Aladdin Ghostscript and GNU Ghostscript are different releases. If you have Aladdin Ghostscript, not the GNU Ghostscript releases distributed by the Free Software Foundation, 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, rather than just use an executable you got from somewhere, you should 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

What if I'm a developer?

If you are going to write a new driver for Ghostscript, you should read

If you are considering distributing Ghostscript (either Aladdin or GNU 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, 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

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
