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 in‐
       put comes from stdin, the names are noname.red, noname.grn, and noname.blu.

OPTIONS
       There are no command line options defined specifically for ppmtorgb3, but it recognizes the  options  common  to	 all
       programs based on libnetpbm (See	 Common Options .)
