resize ImageIcon within JPanel where file is retrieved from a folder

Question

I wish to resize an ImageIcon within a JPanel, and I know there are suggestions everywhere, where it does not work for the following no matter how I edit it. The following is one of the many attempts, which i find closest to my aim.

With courtesy from: resizing a ImageIcon in a JButton

How can i rectify my code?

        JLabel lblFoodPicUrl = new JLabel();
        lblFoodPicUrl.setPreferredSize(new Dimension (50,50));
        lblFoodPicUrl.setIcon (new ImageIcon (PlaceOrder.class.getResource("/Pictures/" + food_Pic_Url + ".jpg")));
        lblFoodPicUrl.setHorizontalAlignment (SwingConstants.CENTER);


        Image img = (Image) lblFoodPicUrl.getIcon();
        Image newing = img.getScaledInstance(20, 20, java.awt.Image.SCALE_SMOOTH);
        lblFoodPicUrl = new ImageIcon (newing);

`lblFoodPicUrl = new ImageIcon (newing);` what this code is supposed to do ? — Sage, Oct 23 '13 at 14:15

Try using Darryl's Stretch Icon. It should dynamically resize the icon if the size of the label ever changes.

try this. but you fixed your label and imageicon size. so it is not bother about jpanel size.

    JLabel lblFoodPicUrl = new JLabel();
    lblFoodPicUrl.setPreferredSize(new Dimension(50, 50));
    lblFoodPicUrl.setIcon(new ImageIcon(getClass().getResource("your path")));
    lblFoodPicUrl.setHorizontalAlignment(SwingConstants.CENTER);
    BufferedImage img = new BufferedImage(lblFoodPicUrl.getIcon().getIconWidth(), lblFoodPicUrl.getIcon().getIconHeight(), BufferedImage.TYPE_INT_RGB);
    Graphics g = img.createGraphics();
    lblFoodPicUrl.getIcon().paintIcon(null, g, 0, 0);
    g.dispose();
    Image newing = img.getScaledInstance(20, 20, java.awt.Image.SCALE_SMOOTH);
    lblFoodPicUrl.setIcon(new ImageIcon(newing));
