Returns a DirectColorModel that describes the default format for integer RGB values used in many of the methods in the AWT image interfaces for the convenience of the programmer.

Usage

From source file:Main.java

public void paint(Graphics g) {
    super.paint(g);
    Graphics2D g2d = (Graphics2D) g;

    GradientPaint gp1 = new GradientPaint(5, 5, Color.red, 20, 20, Color.yellow, true);

    gp1.createContext(ColorModel.getRGBdefault(), new Rectangle(0, 0, 30, 40), new Rectangle(0, 0, 30, 40),
            new AffineTransform(), null);

    System.out.println(gp1.getTransparency());
    g2d.setPaint(gp1);//w  w  w.j  a v a 2s  .  c  om
    g2d.fillRect(20, 20, 300, 40);
