Sets the paint mode of this graphics context to alternate between this graphics context's current color and the new specified color.

Usage

From source file:XORRectangles.java

    // using white as the XOR color.

    g2.transform(AffineTransform.getTranslateInstance(25, 25));
    // Draw a blue rectangle.
