filter(FilterContext fctx,

java.lang.Object renderHelper,

Applies this filter effect to the series of images represented by
the input
Effects and/or the given defaultInput
viewed under the given transform. |
Effect.AccelType |
getAccelType(FilterContext fctx)
Returns one of the
AccelType values, indicating
whether this Effect is accelerated in hardware for the
given FilterContext. |
RectBounds |
getBounds(BaseTransform transform,
Effect defaultInput)
Returns the bounding box that will be affected by this filter
operation when viewed under the specified
transform,
given its list of input Effects and the specified
defaultInput effect. |
DirtyRegionContainer |
getDirtyRegions(Effect defaultInput,
DirtyRegionPool regionPool)
Returns the dirty region container containing dirty regions affected
by this filter operation.
|
boolean |
reducesOpaquePixels()
Whether an opacity for any pixel is different (lower)
than the corresponding pixel in the default input.

public ImageData filter(FilterContext fctx, BaseTransform transform, Rectangle outputClip, java.lang.Object renderHelper, Effect defaultInput)
EffectEffects and/or the given defaultInput
viewed under the given transform.
The filter does not need to create pixel data for any pixels that
fall outside of the destination device-space (pixel) bounds specified
by the outputClip Rectangle.
The filter might be able to use the renderHelper object to
render the results directly on its own if the object is not null and
implements an interface, such as ImageHelper, that the filter
recognizes.
If the effect renders itself then it will return a null for
the ImageData result.
Note that the ImageData object returned by this method must be
validated prior to use with
ImageData.validate(com.sun.scenario.effect.FilterContext) method.
boolean valid;
do {
ImageData res = filter(fctx, transform, clip, renderer, defaultInput);
if (res == null) {
break;
}
if (valid = res.validate(fctx)) {
// Render res.getImage() to the appropriate destination
// or use it as an input to another chain of effects.
}
res.unref();
} while (!valid);
