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);
    poly.addPt(0,99);
    im.filledPolygon(poly, blue);
    # Output binary image in PNG format

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.
