- NAME
- psidtopgm - convert PostScript "image" data into a portable
- graymap
-
- SYNOPSIS
- psidtopgm <width> <height> <bits/sample> [imagedata]
-
- DESCRIPTION
- 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 _m_a_n_u_a_l_l_y 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 _a_t _l_e_a_s_t 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...
