An intermediate mix-in superclass that performs the multi-pass filtering algorithm common to all linear convolution filters such as Gaussian, Box, and Motion Blurs and Shadows. In particular, it is used for all filters that use the LinearConvolve and LinearConvolveShadow shader peers.

Method Summary

Modifier and TypeMethod and Description
public ImageData
filterImageDatas(FilterContext fctx, BaseTransform transform, Rectangle outputClip, LinearConvolveRenderState lcrstate, ImageData... inputs)

Overrides com.sun.scenario.effect.CoreEffect.filterImageDatas.

Convenience method that sends the given input data through the current peer, and then attempts to release the input image data.

public final LinearConvolveRenderState
getRenderState(FilterContext
the context object that would be used by the Renderer if this call is preparing for a render operation, or null
fctx, BaseTransform
the transform for the output of this operation
transform, Rectangle
the clip rectangle that may restrict this operation, or null
outputClip, Object
the rendering helper object that can be used to shortcut this operation under certain conditions, or null
renderHelper, Effect
the Effect to be used in place of any null inputs
defaultInput)

Implements abstract com.sun.scenario.effect.FilterEffect.getRenderState.

Returns the object representing the rendering strategy and state for the filter operation characterized by the specified arguments.

pack-priv abstract LinearConvolveKernel
getState()

Overrides com.sun.scenario.effect.Effect.getState.

Returns state object that is associated with this effect instance.

public final LinearConvolveRenderState getRenderState(FilterContext fctx, BaseTransform transform, Rectangle outputClip, Object renderHelper, Effect defaultInput)

Implements abstract com.sun.scenario.effect.FilterEffect.getRenderState.

Doc from com.sun.scenario.effect.FilterEffect.getRenderState.

Returns the object representing the rendering strategy and state for the filter operation characterized by the specified arguments. This call can also be used to get a state object for non-rendering cases like querying the bounds of an operation in which case the FilterContext object may be null. outputClip and renderHelper may always be null just as they may be null for a given filter operation.

Parameters
fctx:FilterContext

the context object that would be used by the Renderer if this call is preparing for a render operation, or null

transform:BaseTransform

the transform for the output of this operation

outputClip:Rectangle

the clip rectangle that may restrict this operation, or null

renderHelper:Object

the rendering helper object that can be used to shortcut this operation under certain conditions, or null

defaultInput:Effect

the Effect to be used in place of any null inputs

pack-priv abstract LinearConvolveKernel getState()

Overrides com.sun.scenario.effect.Effect.getState.

Doc from com.sun.scenario.effect.Effect.getState.

Returns state object that is associated with this effect instance. Subclasses may override this method to return some sort of state object that contains implementation details that are hidden from the public API. Classes outside this package can use the AccessHelper class to get access to this package-private method.
