NAME

   ppmtorgb3 - separate a PPM image into three PGMs

SYNOPSIS

   ppmtorgb3 [ppmfile]

DESCRIPTION

   This program is part of Netpbm.

   ppmtorgb3  reads a PPM image as input and writes three PGM im-
ages as output,
   one each for red, green, and blue.

   ppmtorgb3 constructs the output filenames by taking the  input
filename,
   stripping  off  any extension, and appending .red, .grn, .blu.
For example,
   separating lenna.ppm would result in lenna.red, lenna.grn, and
lenna.blu. If
   the	 input	comes  from stdin, the names are noname.red, non-
ame.grn, and
   noname.blu.
