NAME
       Template::Plugin::GD::Polygon - Interface to GD module Polygon class

SYNOPSIS
           [% USE poly = GD.Polygon;
              poly.addPt(50,0);
              poly.addPt(99,99);
           %]

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);

               # make the background transparent and interlaced
               im.transparent(white);
               im.interlaced('true');

               # Put a black frame around the picture
               im.rectangle(0,0,99,99,black);

               # Draw a blue oval
               im.arc(50,50,95,75,0,360,blue);

               # And fill it with red
               im.fill(50,50,red);

               # Draw a blue triangle by defining a polygon
               USE poly = GD.Polygon;
               poly.addPt(50,0);
               poly.addPt(99,99);

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.

       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.
