- Reads the "image" data from a PostScript file as input.
- Produces a portable graymap as output.
-
- 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 mmmmaaaannnnuuuuaaaallllllllyyyy 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 aaaatttt lllleeeeaaaasssstttt 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...
