The Template-GD distribution provides a number of Template Toolkit plugin modules to interface with Lincoln Stein's \s-1GD\s0 modules. These in turn provide an interface to Thomas Boutell's \s-1GD\s0 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>. For information on using plugins, see Template::Plugins and \*(L"\s-1USE\s0\*(R" in Template::Manual::Directives.

The \s-1GD\s0 plugin module provides a number of methods to create various other \s-1GD\s0 objects. But first you need to load the \s-1GD\s0 plugin.

[% USE GD %]

Then you can call the following objects against it.

\$1

Creates a new GD::Image object.

[% image = GD.image(100, 200) %] 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); %] Creates a new GD::Text object.

[% text = GD.text; text.set_text('Some text'); %]

These are the \s-1GD\s0 plugins provided in this distribution. Front-end module to the \s-1GD\s0 plugin collection. Plugin interface providing direct access to the GD::Image module.

[% USE image = GD.Image %] Plugin interface providing direct access to the GD::Polygon module.

[% USE poly = GD.Polygon; poly.addPt(50,0); poly.addPt(99,99); poly.addPt(0,99); image.filledPolygon(poly, blue); %] Plugin interface providing direct access to the GD::Text module.

[% USE text = GD.Text; text.set_text('Some text'); %] Plugin interface to the GD::Text::Align module for creating aligned text. Plugin interface to the GD::Text::Wrap module for creating wrapped text. Plugin interface to the GD::Graph::area module for creating area graphics with axes and legends. Plugin interface to the GD::Graph::bars3d module for creating 3D bar graphs with axes and legends. Plugin interface to the GD::Graph::bars module for creating bar graphs with axes and legends. Plugin interface to the GD::Graph::lines3d module for creating 3D line graphs with axes and legends. Plugin interface to the GD::Graph::lines module for creating line graphs with axes and legends. Plugin interface to the GD::Graph::linespoints module for creating line/point graphs with axes and legends Plugin interface to the GD::Graph::mixed module for creating mixed graphs with axes and legends. Plugin interface to the GD::Graph::pie3d module for creating 3D pie charts with legends. Plugin interface to the GD::Graph::pie module for creating pie charts with legends. Plugin interface to the GD::Graph::points module for creating point graphs with axes and legends Provides access to various \s-1GD\s0 constants.

[% USE gdc = GD.Constants; font = gdc.gdLargeFont %]
