<H2>DESCRIPTION</H2>
|
|
|
|
Reads a portable pixmap as input.
|
|
Writes three portable graymaps as output, one each for red, green, and blue.
|
|
<A NAME="ixAAC"></A>
|
|
<P>
|
|
|
|
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.
