DESCRIPTION ^

This module is used to add caption text to raw RGB data such as that found in PPM files or grabbed from a frame grabber card using Video4linux.

This code was written in C by Jamie Zawinski <jwz@jwz.org> as found at http://www.jwz.org/ppmcaption/ and ported to perl (perlxs) by myself.
