NAME
psidtopgm - convert PostScript "image" data to a PGM image
SYNOPSIS
psidtopgm width height bits/sample [imagedata]
DESCRIPTION
This program is part of Netpbm(1).
psidtopgm reads the "image" data from a PostScript file as input and
produces a PGM image as output.
This program is obsoleted by pstopnm.
What follows was written before pstopnm existed.
This is a very simple and limited program, and is here only because so
many people have asked for it. To use it you have to manually extract
the readhexstring data portion from your PostScript file, and then give
the width, height, and bits/sample on the command line. Before you at-
tempt this, you should at least read the description of the "image" op-
erator in the PostScript Language Reference Manual.
It would probably not be too hard to write a script that uses this fil-
ter to read a specific variety of PostScript image, but the variation
is too great to make a general-purpose reader. Unless, of course, you
want to write a full-fledged PostScript interpreter...
