Class BufferedImageFilter

java.lang.Object

java.awt.image.ImageFilter

java.awt.image.BufferedImageFilter

All Implemented Interfaces:

ImageConsumer, Cloneable

public class BufferedImageFilter
extends ImageFilter
implements Cloneable

The BufferedImageFilter class wraps BufferedImageOp objects in a Filter. When pixels are pushed through the filter, we create a BufferedImage, apply the BufferedImageOp, and pass the filtered pixels to the base class.
