Class GaussianShadowState

java.lang.Object

com.sun.scenario.effect.impl.state.LinearConvolveKernel

com.sun.scenario.effect.impl.state.HVSeparableKernel

com.sun.scenario.effect.impl.state.GaussianBlurState

com.sun.scenario.effect.impl.state.GaussianShadowState

public class GaussianShadowState
extends GaussianBlurState

The helper class for defining a 1 dimensional linear convolution shadow kernel for the Gaussian Shadow shader. This class leverages the GaussianBlurState class for defining the kernel and simply stores additional shadowColor and spread properties for the associated support methods for the shadow version of the shader.
