Class BoxShadowState

java.lang.Object

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

public class BoxShadowState
extends BoxBlurState

The helper class for defining a 1 dimensional linear convolution shadow kernel for the LinearConvolveShadow Shader. This class leverages the BoxBlurState 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.
