psidtopgm - convert PostScript "image" data into a portable graymap
psidtopgm width height bits/sample [imagedata]
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
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...
