black = img.colorAllocate(0, 0, 0);
red = img.colorAllocate(255, 0, 0);

DESCRIPTION
The Template-GD distribution provides a number of Template Toolkit
plugin modules to interface with Lincoln Stein's GD modules. These in
turn provide an interface to Thomas Boutell's GD graphics library.
These plugins were distributed as part of the Template Toolkit until
version 2.15 released in February 2006. At this time they were
extracted into this separate distribution.
For general information on the Template Toolkit see the documentation
for the Template module or http://template-toolkit.org
<http://template-toolkit.org>. For information on using plugins, see
Template::Plugins and "USE" in Template::Manual::Directives.
METHODS
The GD plugin module provides a number of methods to create various
other GD objects. But first you need to load the GD plugin.
[% USE GD %]
Then you can call the following objects against it.
image(width, height)
Creates a new GD::Image object.
[% image = GD.image(100, 200) %]
polygon()
Creates a new GD::Polygon object.
[% poly = GD.polygon;
poly.addPt(50,0);
poly.addPt(99,99);
poly.addPt(0,99);
image.filledPolygon(poly, blue);
%]
text()
Creates a new GD::Text object.
[% text = GD.text;
text.set_text('Some text');
%]
