Usage

From source file:XORRectangles.java

    // using white as the XOR color.
    g2.setXORMode(Color.white);// w  ww  . j  a v  a2  s.c om
    // Paint a red rectangle.
    Rectangle2D r = new Rectangle2D.Double(50, 50, 150, 100);
    g2.setPaint(Color.red);
    g2.fill(r);
    g2.transform(AffineTransform.getTranslateInstance(25, 25));
    // Draw a blue rectangle.
    g2.setPaint(Color.blue);
    g2.fill(r);
}

From source file:Main.java

    // we need to cast to Graphics2D for this operation
    Graphics2D g2d = (Graphics2D) g;

    // save the old paint
    Paint oldPaint = g2d.getPaint();

    // set the paint to use for this operation
    g2d.setPaint(paint);

    // fill the background using the paint
    g2d.fillRect(0, 0, width, height);//w w w .  j  a  v a2 s  .c om

    // restore the original paint
    g2d.setPaint(oldPaint);
