## 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)](https://www.chedong.com/phpMan.php/man/Netpbm/1/markdown).

       **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.  Be‐
       fore 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) .)
