Rotate with AffineTransform in Java

Description

The following code shows how to rotate with AffineTransform.

Example


import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.geom.AffineTransform;
/*  w  w w.  ja va 2 s.  co  m*/
import javax.swing.JComponent;
import javax.swing.JFrame;

class MyCanvas extends JComponent {
  public void paint(Graphics g) {
    Graphics2D g2d = (Graphics2D) g;
    AffineTransform transform = AffineTransform.getRotateInstance(Math.PI / 16.0d);
    g2d.setTransform(transform);

    g2d.setFont(new Font("Helvetica", Font.BOLD, 24));
    String text = "java2s.com";
    g2d.drawString(text, 300, 50);
  }
}

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.
