PROGRAM:
NAME
ppmtorgb3 - separate a portable pixmap into three portable graymaps
SYNOPSIS
ppmtorgb3 [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Writes three portable graymaps as output, one each for
red, green, and blue.
The output filenames are constructed by taking the input filename, stripping off any
extension, and appending ".red", ".grn", and ".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, noname.grn, and noname.blu.
