Animated gif resizing problem

Question

Im trying to achieve the following: showing an animated gif that resizes to fill the area of a canvas. I tried the easy way: adding a label and setting the icon for that label, but when trying to resize the image it doesnt show (see code below). Is there any particular way of resizing an animated gif? can the labe-icon approach be used with animated gif that must be resized?
Thanks a lot in advance.
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Image;
import javax.swing.ImageIcon;
public class TestFrame extends javax.swing.JFrame {
/** Creates new form TestFrame */
public TestFrame() {
initComponents();
Image image = this.getToolkit().getImage("C:\\multivideo\\img\\39.gif");
Dimension dim = jLabel1.getPreferredSize();
image = image.getScaledInstance(dim.width, dim.height, Image.SCALE_SMOOTH);
ImageIcon i = new ImageIcon(image);
jLabel1.setIcon(i);
jLabel1.setBackground(Color.BLUE);
pack();
/** This method is called from within the constructor to
* initialize the form.
private void initComponents()
jLabel1 = new javax.swing.JLabel();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
jLabel1.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
jLabel1.setIcon(new javax.swing.ImageIcon("C:\\multivideo\\img\\40.gif"));
jLabel1.setMaximumSize(new java.awt.Dimension(1436, 86));
jLabel1.setMinimumSize(new java.awt.Dimension(1436, 86));
jLabel1.setPreferredSize(new java.awt.Dimension(1436, 86));
getContentPane().add(jLabel1, java.awt.BorderLayout.CENTER);
pack();
* @param args the command line arguments
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new TestFrame().setVisible(true);
private javax.swing.JLabel jLabel1;
}

I don't think getScaledInstance is smart enough to return a scaled image.
You could try doing your own scaling:
import java.awt.*;
import java.awt.geom.*;
import java.net.*;
import javax.swing.*;
public class Animated extends JComponent {
    private Image image;
    private double scale;
    public Animated(URL url, double scale) {
        image = new ImageIcon(url).getImage();
        this.scale = scale;
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Insets insets = getInsets();
        Graphics2D g2 = (Graphics2D) g.create();
        g2.translate(insets.left, insets.top);
        g2.scale(scale, scale);
        g2.drawImage(image, 0, 0, this);
        g2.dispose();
    public Dimension getPreferredSize() {
        Insets insets = getInsets();
        int w = insets.left + insets.right + (int)(scale*image.getWidth(null));
        int h = insets.top + insets.bottom + (int)(scale*image.getHeight(null));
        return new Dimension(w,h);
    public static void main(String[] args) throws MalformedURLException {
        URL url = new URL("http://members.aol.com/royalef/sunglass.gif");
        final JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(new Animated(url, 2), BorderLayout.NORTH);
        f.getContentPane().add(new Animated(url, 1), BorderLayout.SOUTH);
        f.pack();
        SwingUtilities.invokeLater(new Runnable(){
            public void run() {
                f.setLocationRelativeTo(null);
                f.setVisible(true);
}Or you could explicitly extract the images from the animated gif and
resize them individually. The sample code here does the extraction:
