SWFGradient::__construct

(PHP 5 <= 5.3.0, PECL ming SVN)
Creates a gradient object
SWFGradient::__construct ( void )

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.
