Example

In the following code shows how to use Arc2D.setArcByTangent(Point2D p1, Point2D p2, Point2D p3, double radius) method.

//  w  w w . jav  a  2  s .c  o  m
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Point;
import java.awt.geom.Arc2D;

import javax.swing.JFrame;
import javax.swing.JPanel;

public class Main extends JPanel {

  public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D) g;
    int w = getSize().width;
    int h = getSize().height;

    Arc2D arc = new Arc2D.Double(0.0, 0.5, w, h, 0.0, 60.0, Arc2D.CHORD);

    g2.draw(arc);

    
    arc.setArcByTangent(new Point(2, 3),new Point(3, 4), new Point(3, 4), Arc2D.PIE);
    g2.fill(arc);

    arc = new Arc2D.Float(0.0f, 0.0f, w, h, 210.0f, 130.0f, Arc2D.OPEN);

    g2.draw(arc);
  }

  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.getContentPane().add(new Main());

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(200, 200);
    frame.setVisible(true);
  }
}
