Interface to Gd Graphics Library
This is an autoloadable interface module for libgd, a popular library
for creating and manipulating PNG files. With this library you can
create PNG images on the fly or modify existing files.
This version of GD no longer supports GIF output because of threats
from the legal department at Unisys. Source code that calls
$image->gif will have to be changed to call either $image->jpg or
$image->png to output in JPEG or PNG formats. The last version of GD
that supported GIF output was version 1.19.
