Applying a gradient bevel filter
The GradientBevelFilter class lets you apply a gradient bevel effect to objects in Flash. A
gradient bevel is a beveled edge that’s enhanced with gradient color on the outside, inside, or
top of an object. Beveled edges bring a three-dimensional look to objects, and can have
colorful results as shown in the following figure.
For more information on this filter, see GradientBevelFilter
(flash.filters.GradientBevelFilter) in the ActionScript 2.0 Language Reference.
The following procedure uses the Drawing API to draw a square on the Stage, and applies a
gradient bevel filter to the shape.
