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 extension, 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.
