DESCRIPTION

30       The Template-GD distribution provides a number of Template Toolkit
31       plugin modules to interface with Lincoln Stein's GD modules.  These in
32       turn provide an interface to Thomas Boutell's GD graphics library.
33
34       These plugins were distributed as part of the Template Toolkit until
35       version 2.15 released in February 2006.  At this time they were
36       extracted into this separate distribution.
37
38       For general information on the Template Toolkit see the documentation
39       for the Template module or <http://template-toolkit.org>.  For
40       information on using plugins, see Template::Plugins and "USE" in
41       Template::Manual::Directives.

METHODS

44       The GD plugin module provides a number of methods to create various
45       other GD objects.  But first you need to load the GD plugin.
46
47           [% USE GD %]
48
49       Then you can call the following objects against it.
50
51   image(width, height)
52       Creates a new GD::Image object.
53
54           [% image = GD.image(100, 200) %]
55
56   polygon()
57       Creates a new GD::Polygon object.
58
59           [% poly = GD.polygon;
60              poly.addPt(50,0);
61              poly.addPt(99,99);
62              poly.addPt(0,99);
63              image.filledPolygon(poly, blue);
64           %]
65
66   text()
67       Creates a new GD::Text object.
68
69           [%  text = GD.text;
70               text.set_text('Some text');
71           %]
72
