| <H2>DESCRIPTION</H2> |
| |
| <p>This program is part of <a href="index.html">Netpbm</a>. |
| |
| <p><b>psidtopgm</b> reads the "image" data from a PostScript |
| file as input and produces a PGM image as output. |
| |
| <P>This program is obsoleted by <B>pstopnm</B>. |
| |
| What follows was written before <B>pstopnm </B> existed. |
| |
| <P>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 |
| <em>manually</em> 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 <em>at |
| least</em> read the description of the "image" operator in |
| the PostScript Language Reference Manual. |
| |
| <P>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... |
