NAME
       pgmtopgm - copy PGM image

SYNOPSIS
       pgmtopgm

DESCRIPTION
       This program is part of Netpbm(1).

       pgmtopgm	 simply copies a PGM image from Standard Input to Standard Output.  This may seem an unnecessary duplication
       of cat, but remember that a PGM program can read a PBM image as if it were PGM.	So pgmtopgm can read either a PBM or
       PGM image and produce a PGM image as output.

       Even that is of limited usefulness because of the fact that almost any program to which you would feed the  resulting
       PGM image could also just take the original image directly.  However, sometimes you really need a true PGM image.

       When you know you have a PBM image and want a PGM image, pbmtopgm is a more general way to do that conversion.

OPTIONS
       There are no command line options defined specifically for pgmtopgm, but it recognizes the options common to all pro‐
