NAME

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

SYNOPSIS

   psidtopgm width height bits/sample [imagedata]

DESCRIPTION

   This program is part of Netpbm.

   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  writ-
ten 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 ex-
tract 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" opera-
tor 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...
