如何在JLabel中调整Image / IconImage的大小？

这是我的代码：

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); 

现在，从图标中提取的图像非常小。 我该如何resize？

 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))); } }
