Usage

From source file:TransformersRotation.java

public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D) g;

    // Use antialiasing.
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

    // Move the origin to 75, 75.
    AffineTransform at = AffineTransform.getTranslateInstance(75, 75);
    g2.transform(at);

    // Draw the shapes in their original locations.
    g2.setPaint(Color.black);//from  w ww.  j a v a2s  . c  o  m
    g2.draw(axes);
    g2.draw(shape);
