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 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.
