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 GD for a complete description of the GD library and all the methods
that can be called via the GD.Image plugin. See
Template::Plugin::GD::Constants for a plugin that allows you access to
GD.pm's constants.
