请教：有没有办法把JScrollPane或者JInternalFrame的画面抓到Image或者ImageIcon里面？

[www203]

因为我想把他保存成图片
或者把画面的内容打印到PDF上面

public class T {
public static void main(String[] args) {
JDesktopPane desktop = new JDesktopPane();
final JInternalFrame internalframe = new JInternalFrame("Test", true, false, true, true);
internalframe.getContentPane().add(new JLabel("Hello World!", JLabel.CENTER));
internalframe.setSize(150, 100);
internalframe.setVisible(true);
desktop.add(internalframe);

JButton imgBtn = new JButton(new AbstractAction() {
{ putValue(NAME, "SaveImage"); }

public void actionPerformed(ActionEvent e) {
BufferedImage img = new BufferedImage(
internalframe.getWidth(), internalframe.getHeight(),
BufferedImage.TYPE_INT_RGB);
Graphics g = img.getGraphics();
internalframe.paint(g);
g.dispose();

try {
ImageIO.write(img, "png", new File("test.png"));
} catch (IOException e1) {
e1.printStackTrace();
}
}
});

JFrame f = new JFrame();
f.getContentPane().add(desktop, BorderLayout.CENTER);
f.getContentPane().add(imgBtn, BorderLayout.SOUTH);
f.setSize(300, 300);
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
}
}
