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
       recommended 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.
