- 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 mmmaaannnuuuaaallllllyyy 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 aaattt llleeeaaasssttt 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...
