SYNOPSIS

DESCRIPTION

16       This program is part of Netpbm(1).
17
18       ppmtorgb3  reads  a  PPM  image as input and writes three PGM images as
19       output, one each for red, green, and blue.
20
21       ppmtorgb3 constructs the output filenames by taking the input filename,
22       stripping off any extension, and appending .red, .grn, .blu.  For exam‐
23       ple, separating lenna.ppm would result  in  lenna.red,  lenna.grn,  and
24       lenna.blu.   If  the  input comes from stdin, the names are noname.red,
25       noname.grn, and noname.blu.
