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 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...
