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 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...
