Using a shader

Once a Pixel Bender shader is available in ActionScript as a Shader object, it can be used in several ways:

• Shader drawing fill: The shader defines the fill portion of a shape drawn using the drawing api

• Blend mode: The shader defines the blend between two overlapping display objects

• Filter: The shader defines a filter that modifies the appearance of visual content

• Stand-alone shader processing: The shader processing runs without specifying the intended use of the output. The shader can optionally run in the background, with the result is available when the processing completes. This technique can be used to generate bitmap data and also to process non-visual data.
