portable graymap
SYNOPSISpsidtopgm 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 por
tion 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...
