       pgmtopgm - copy PGM image




       This program is part of Netpbm(1).

       pgmtopgm simply copies a PGM image from Standard Input to Standard Out-
       put.  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.
