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.
