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

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

[% FILTER null;
    USE gdc = GD.Constants;
    USE im  = GD.Image(200,100);
    black = im.colorAllocate(0  ,0,  0);
    red   = im.colorAllocate(255,0,  0);
    r = im.string(gdc.gdLargeFont, 10, 10, "Large Red Text", red);
    im.png | stdout(1);

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.
