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  spe-
       cific  variety  of PostScript image, but the variation is too great to make a general-pur-
       pose reader.  Unless, of course, you  want  to  write  a  full-fledged  PostScript  inter-
       preter...
