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...
