Template::Plugin::GD::Constants - Interface to GD module constants

    [% USE gdc = GD.Constants %]
    # --> the constants gdc.gdBrushed, gdc.gdSmallFont, gdc.GD_CMP_IMAGE

        red   = im.colorAllocate(255,0,  0);

The GD.Constants plugin provides access to the various GD module's constants (such as gdBrushed, gdSmallFont, gdTransparent, GD_CMP_IMAGE etc). When GD.pm is used in perl it exports various contstants into the caller's namespace. This plugin makes those exported constants available as template variables.

See Template::Plugin::GD::Image and GD for further examples and details.
