ppmtorgb3(1)                         General Commands Manual                         ppmtorgb3(1)

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  ex-
       tension,  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.
