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 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.
