Comment redimensionner Image/IconImage dans JLabel?

Question

Voici mon code:

String s = "/Applications/Asphalt6.app"; 
JFileChooser chooser = new JFileChooser(); 

File file = new File(s); 
Icon icon = chooser.getIcon(file); 

// show the icon 
JLabel ficon = new JLabel(s, icon, SwingConstants.LEFT); 

Maintenant, l'image extraite de l'icône est vraiment petit. Comment puis-je le redimensionner?

import java.awt.*; 
import java.awt.image.*; 
import javax.swing.*; 
import java.io.*; 

class BigIcon { 

    public static void main(String[] args) { 
     JFileChooser chooser = new JFileChooser(); 
     File f = new File("BigIcon.java"); 
     Icon icon = chooser.getIcon(f); 

     int scale = 4; 

     BufferedImage bi = new BufferedImage(
      scale*icon.getIconWidth(), 
      scale*icon.getIconHeight(), 
      BufferedImage.TYPE_INT_ARGB); 
     Graphics2D g = bi.createGraphics(); 
     g.scale(scale,scale); 
     icon.paintIcon(null,g,0,0); 
     g.dispose(); 

     JOptionPane.showMessageDialog(
      null, 
      new JLabel(new ImageIcon(bi))); 
    } 
}
