This class is used in conjunction with a FilteredImageSource. It accepts image data through the ImageConsumer interface and passes it on to an ImageConsumer specified by the controlling FilteredImageSource. ImageFilter is the superclass of all image filters, and performs no filtering itself. You must subclass it to perform the desired filtering. See CropImageFilter and RGBImageFilter. The ImageFilter methods are the ImageConsumer methods invoked by an ImageProducer. You should not call them directly.
See FilteredImageSource for an example of using an ImageFilter.
