getDirtyRegions(Effect defaultInput,
DirtyRegionPool regionPool)
Returns the dirty region container containing dirty regions affected
by this filter operation.
|
Effect |
getInput()
Returns the input for this
Effect . |
int |
getRadius()
Returns the radius of the effect kernel.
|
RenderState |
getRenderState(FilterContext fctx,
BaseTransform transform,
Rectangle outputClip,
Object renderHelper,
Effect defaultInput)
Returns the object representing the rendering strategy and state for
the filter operation characterized by the specified arguments.
|
boolean |
reducesOpaquePixels()
Whether an opacity for any pixel is different (lower)
than the corresponding pixel in the default input.
|
void |
setCenterX(float centerX)
Sets the X coordinate of the center point of this effect.
|
void |
setCenterY(float centerY)
Sets the Y coordinate of the center point of this effect.
|
void |
