Class RadialGradientPaint

java.lang.Object

com.highqsoft.util.graphics.RadialGradientPaint

All Implemented Interfaces:

java.awt.Paint, java.awt.Transparency

public class RadialGradientPaint
extends java.lang.Object
implements java.awt.Paint

This class provides a way to fill a shape with a radial color gradient pattern. Given an Ellipse and 2 Colors, color1 and color2, the paint will render a color starting at color1 at the center of the Ellipse to color2 at its boundary. All pixels lying outside the Ellipse boundary have the color2 value.
