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');
           %]
