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.

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
74 These are the GD plugins provided in this distribution.

90 poly.addPt(0,99);
91 image.filledPolygon(poly, blue);
92 %]
93
94 Template::Plugin::GD::Text
95 Plugin interface providing direct access to the GD::Text module.
