Create an Image from a Component

Question

Can anybody tell me how to create an Image from a Component?
I intend to create an Image from a JTable now but I want to have a more generic solution of course to be able to create an Image from any Java / Swing component (Applet, JList, JButton, ...).
Thank you,
Dirk

2 ways:
1) java.awt.Toolkit.createScreenCapture(Rectangle bounds)
2) This:
     public static BufferedImage grabByPaint(Component comp) {
          boolean visible = comp.isVisible();
          // if not visible, need to make visible to make sure sizes are correct. 
          if(!visible) {
               comp.setVisible(true);
          Dimension size = comp.getSize();
          BufferedImage bi = new BufferedImage(size.width, size.height, BufferedImage.TYPE_INT_ARGB);
          Graphics2D g2d = bi.createGraphics();
          comp.paintAll(g2d);
          if(!visible) {
               comp.setVisible(false);
          g2d.dispose();
          return bi;
     }
