The GD.Polygon plugin provides an interface to GD.pm's GD::Polygon class.

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.

Thomas Boutell wrote the GD graphics library.

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

Craig Barratt <craig@arraycomm.com> wrote the original GD plugins for the Template Toolkit (2001).

Andy Wardley <abw@cpan.org> extracted them from the TT core into a separate distribution for TT version 2.15.
