NAME

       psidtopgm - convert PostScript "image" data to a PGM image

SYNOPSIS

       psidtopgm width height bits/sample [imagedata]

DESCRIPTION

       This program is part of Netpbm(1).

       psidtopgm  reads the "image" data from a PostScript file as input and produces a PGM image
       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...

OPTIONS

       There  are  no  command line options defined specifically for psidtopgm, but it recognizes
       the options common to all programs based on libnetpbm (See
        Common Options ⟨index.html#commonoptions⟩ .)
