Class GradientFilter

java.lang.Object

com.jhlabs.image.AbstractBufferedImageOp

com.jhlabs.image.GradientFilter

All Implemented Interfaces:

java.awt.image.BufferedImageOp, java.lang.Cloneable

public class GradientFilter
extends AbstractBufferedImageOp

A filter which draws a coloured gradient. This is largely superceded by GradientPaint in Java1.2, but does provide a few more gradient options.
