Usage

From source file:Main.java

public static void main(String[] args) throws IOException {
    URL url = new URL("http://www.java2s.com/style/download.png");
    BufferedImage im = ImageIO.read(url);
    URL url2 = new URL("http://www.java2s.com/style/download.png");
    BufferedImage im2 = ImageIO.read(url2);
    Graphics2D g = im.createGraphics();
    g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.4f));
    g.drawImage(im2, (im.getWidth() - im2.getWidth()) / 2, (im.getHeight() - im2.getHeight()) / 2, null);
    g.dispose();/* w w w  .  jav a 2s . c  o  m*/

    display(im);
