NAME ^

Template::Plugin::GD - GD plugin(s) for the Template Toolkit

SYNOPSIS ^

    [% USE GD;
     
       # create an image
       img = GD.image(width, height)

       # allocate some colors
       black = img.colorAllocate(0,   0,   0);
       red   = img.colorAllocate(255, 0,   0);
       blue  = img.colorAllocate(0,   0, 255);

       # draw a blue oval
       img.arc(50, 50, 95, 75, 0, 360, blue);

       # fill it with red
       img.fill(50, 50, red);

       # output binary image in PNG format
       img.png | redirect('example.png');
    %]

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. 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');
    %]
