=head1 DESCRIPTION
The GD.Image plugin provides an interface to GD.pm's GD::Image class.
The GD::Image class is the main interface to GD.pm.
It is very important that no extraneous template output appear before or
after the image. Since some methods return values that would otherwise
appear in the output, it is recommended that GD.Image code be wrapped in
a null filter. The methods that produce the final output (eg, png, jpeg,
gd etc) can then explicitly make their output appear by using the
stdout filter, with a non-zero argument to force binary mode (required
for non-modern operating systems).
See L<GD> for a complete description of the GD library and all the
methods that can be called via the GD.Image plugin.
See L<Template::Plugin::GD::Constants> for a plugin that allows you
access to GD.pm's constants.
