EXAMPLES

     [% FILTER null;
         USE im   = GD.Image(100,100);
         USE c    = GD.Constants;
 
         # allocate some colors
         white = im.colorAllocate(255,255,255);
         black = im.colorAllocate(0,  0,  0);
         red   = im.colorAllocate(255,0,  0);
         blue  = im.colorAllocate(0,  0,255);
         green = im.colorAllocate(0,  255,0);

DESCRIPTION

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.

AUTHOR

Thomas Boutell wrote the GD graphics library.

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.
