DESCRIPTION
The GD.Image plugin provides an interface to GD.pm's GD::Image class. The GD::Image class
is the main interface to GD.pm.
It is very important that no extraneous template output appear before or after the image.
Since some methods return values that would otherwise appear in the output, it is recom-
mended that GD.Image code be wrapped in a null filter. The methods that produce the final
output (eg, png, jpeg, gd etc) can then explicitly make their output appear by using the
stdout filter, with a non-zero argument to force binary mode (required for non-modern
operating systems).
See GD for a complete description of the GD library and all the methods that can be called
via the GD.Image plugin. See Template::Plugin::GD::Constants for a plugin that allows you
access to GD.pm's constants.
