Usage

From source file:Transparency.java

    Graphics2D g = target.createGraphics();
    // Set the Graphics composite to Alpha
    g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, (float) alpha));
    // Draw the image into the prepared reciver image
    g.drawImage(source, null, 0, 0);/*from w w w  . ja v  a 2  s  .c  o  m*/
