SWFGradient

Description

swfgradient() creates a new SWFGradient object.

After you've added the entries to your gradient, you can use the gradient in a shape fill with the swfshape->addfill() method.

SWFGradient has the following methods : swfgradient->addentry().

This simple example will draw a big black-to-white gradient as background, and a reddish disc in its center.
