See GD for a complete description of the GD library and all the methods that can be called via the GD.Polygon plugin. See Template::Plugin::GD::Image for the main interface to the GD functions. See Template::Plugin::GD::Constants for a plugin that allows you access to GD.pm's constants.

Lincoln D. Stein wrote the Perl GD modules that interface to it.

Craig Barratt <[email protected]> wrote the original GD plugins for the Template Toolkit (2001).

Andy Wardley <[email protected]> extracted them from the TT core into a separate distribution for TT version 2.15.
