       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
       pstopnm existed.

       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...
