NAME
       psidtopgm - convert PostScript "image" data into a portable graymap

SYNOPSIS
       psidtopgm width height bits/sample [imagedata]

DESCRIPTION
       Reads  the  "image"  data  from a PostScript file as input.  Produces a
       portable graymap 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...
