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.
