NAME

   ppmtoppm - copy PPM image

SYNOPSIS

   ppmtoppm

DESCRIPTION

   This program is part of Netpbm.

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

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

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