       psidtopgm - convert PostScript ’image’ data to a PGM image



       width height bits/sample



       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 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...
