Simple Gradient Paint Example
This section illustrates you how to use Gradient Paint.
A gradient refers to a colored strip with two defined endpoints. Both the end
points are defined with different color. Then the colors will starts changes
gradually from one to the other along a straight line between the two
points.
To use a Gradient paint, we have used the class Elipse2D which provides the shape oval. The
class GradientPaint allows you to set up a gradient filled shape with a
linear color gradient pattern.
Here is the code of SimpleGradientPaintExample.java
import java.awt.*;
import javax.swing.*;
import java.awt.geom.*;
import java.awt.event.*;
public class SimpleGradientPaintExample extends JPanel {
public void init() {
setBackground(Color.gray);
}
public void paint(Graphics graphics) {
Graphics2D g2d = (Graphics2D) graphics;
g2d.setPaint(new GradientPaint(0, 0, Color.cyan, 200,
200, Color.red, false));
Ellipse2D.Double ellipse = new Ellipse2D.Double(5,5,200,200);
g2d.fill(ellipse);
}
public static void main(String args[]) {
JFrame frame = new JFrame("Simple Gradient Paint");
SimpleGradientPaintExample gradientExample = new
SimpleGradientPaintExample();
frame.getContentPane().add("Center",gradientExample);
gradientExample.init();
frame.setSize(new Dimension(300, 250));
frame.show();
}
