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 out‐
       put.

       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.   Be‐
       fore  you  attempt  this, you should at least read the description of the "image" operator in
       the PostScript Language Reference Manual.

       It would probably not be too hard to write a script that uses this filter 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...
