NAME
ppmtorgb3 - separate a PPM image into three PGMs
SYNOPSIS
ppmtorgb3
[ppmfile]
DESCRIPTION
This program is part of Netpbm(1)
ppmtorgb3 reads a PPM image as input and writes three PGM images 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 exam-
ple, separating lenna.ppm would result in lenna.red, lenna.grn, and
lenna.blu. If the input comes from stdin, the names are noname.red,
noname.grn, and noname.blu.
