Enable antialiasing for shapes in Java
Description
The following code shows how to enable antialiasing for shapes.
Example
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
/* ww w . ja v a 2 s .c o m*/
import javax.swing.JComponent;
import javax.swing.JFrame;
class MyCanvas extends JComponent {
public void paint(Graphics g) {
// Retrieve the graphics context; this object is used to paint shapes
Graphics2D g2d = (Graphics2D) g;
// Determine if antialiasing is enabled
RenderingHints rhints = g2d.getRenderingHints();
boolean antialiasOn = rhints.containsValue(RenderingHints.VALUE_ANTIALIAS_ON);
g2d.setFont(new Font("Helvetica", Font.PLAIN, 60));
// Enable antialiasing for shapes
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
g2d.drawString("java2s.com", 30, 200);
}
}
public class Main {
public static void main(String[] a) {
JFrame window = new JFrame();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setBounds(30, 30, 450, 450);
window.getContentPane().add(new MyCanvas());
window.setVisible(true);
}
}
The code above generates the following result.
