[Java] Resizing ImageIcon in Java

Solved

Hello everyone, I have a question regarding ImageIcons in Java, and more specifically their resizing.

My application automatically creates jpg images, which can be of any size. I want to put the created image into a JLabel that has a specific size. Let's say for example 400x400 (just as an example).
How can I ensure that my image appears entirely in the JLabel (so that I don't just see a small portion of my image)?

I have heard about the setImageAutoSize method for TrayIcons; is there an equivalent for ImageIcons...?

Configuration: Mac OS X / Firefox 3.6.3

    ImageIcon icon = new ImageIcon(new ImageIcon("tonImage.jpg").getImage().getScaledInstance(20, 20, Image.SCALE_DEFAULT));

      "Image.SCALE_DEFAULT" is used for default scaling of images, but if you believe that replacing it with a specific number like 20 yields better results, then you should feel free to use that value for your needs.

    ImageIcon icon = new ImageIcon("tonImage.jpg");
    Image img = icon.getImage();
    BufferedImage bi = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB);
    Graphics g = bi.createGraphics();
    g.drawImage(img, 0, 0, WIDTH, HEIGHT, null);
    IconImage newIcon = new IconImage(bi);

    It's not the best way, but it's one :)
