public Class GaussianShadowState

extends GaussianBlurState
Class Inheritance
Imports
com.sun.scenario.effect.Color4f
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.

public boolean
isNop()

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

Returns true if the entire operation of this linear convolution would have no effect on the source data.

public boolean
isShadow()

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

Returns true if this is a LinearConvolveShadow operation, or false if the operation is a regular LinearConvolve.
