Usage

From source file:Composite.java

public void paintComponent(Graphics g) {
    super.paintComponent(g);
    Graphics2D g2 = (Graphics2D) g;

    Dimension d = getSize();//from  w ww.  j  av a  2 s  .c o m
    int w = d.width;
    int h = d.height;

    BufferedImage buffImg = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
    Graphics2D gbi = buffImg.createGraphics();

    g2.setColor(Color.white);
    g2.fillRect(0, 0, d.width, d.height);

    int rectx = w / 4;
    int recty = h / 4;

    gbi.setColor(new Color(0.0f, 0.0f, 1.0f, 1.0f));
    gbi.fill(new Rectangle2D.Double(rectx, recty, 150, 100));
    gbi.setColor(new Color(1.0f, 0.0f, 0.0f, 1.0f));
    gbi.setComposite(ac);
    gbi.fill(new Ellipse2D.Double(rectx + rectx / 2, recty + recty / 2, 150, 100));

    g2.drawImage(buffImg, null, 0, 0);
