Class BoxBlurFilter

java.lang.Object

com.alee.graphics.filters.AbstractBufferedImageOp

com.alee.graphics.filters.BoxBlurFilter

All Implemented Interfaces:

BufferedImageOp

public class BoxBlurFilter
extends AbstractBufferedImageOp

A filter which performs a box blur on an image. The horizontal and vertical blurs can be specified separately and a number of iterations can be given which allows an approximation to Gaussian blur.
