Scale a BufferedImage. (Solved)

[Nate Lockwood]

I have created a buffered image

 biGray = (new BufferedImage(componebtcolormodle, writeableraster, true, hashtable));

Then I construct my GUI as a frame with three panels. The one on which the image is to be displayed is coded:

		JPanel imagePanel = new JPanel();
		imagePanel.setPreferredSize(new Dimension(preferredWidth, preferredHeight));
		ImageIcon imageIcon = new ImageIcon(biGray);
		JLabel imageLabel = new JLabel(imageIcon);
		imagePanel.add(imageLabel);
		frame.getContentPane().add(imagePanel, BorderLayout.CENTER);

The image I'm working with is big, 4004 pixels by 2762 lines, and all that displays is the upper right hand corner. I want to scale it by a factor of 1/3 to fit on my display before displaying it.
I've looked at couple of APIs but I'm new at this and I'm missing something and I don't know how to use the hash table in this context.

Edit
It took a lot of searching and trials but I found a way by creating a class that extends JPanel and putting the code in it;

  @SuppressWarnings("serial")
	class TheImagePanel extends JPanel {
  	public TheImagePanel () {
  		setPreferredSize(new Dimension(preferredWidth, preferredHeight));
  		Graphics2D graphics2D = biGray.createGraphics();
  		graphics2D.setRenderingHint(RenderingHints.KEY_INTERPOLATION,RenderingHints.VALUE_INTERPOLATION_BILINEAR);
  		graphics2D.drawImage(biGray, 0, 0, preferredWidth, preferredHeight, null);
  		graphics2D.dispose();
  	}
  	 public void paint(Graphics g) {

       Graphics2D g2d = (Graphics2D) g;
       g2d.drawImage(biGray, null, 0, 0);
   }
}

In my GUI setup:

		JPanel imagePanel = new JPanel();
		imagePanel.setPreferredSize(new Dimension(preferredWidth, preferredHeight));
		TheImagePanel thePanel = new TheImagePanel();
		imagePanel.add(thePanel);

It all appears to work now (at least to scale an image down) and I can retrieve the pixel values (16 bit gray scale) under the tool tip from the original data.

The above works but is not quite correct if one wants to print or save the image. I found the save image had the reduced size image in the upper right corner of the original image! Here's corrected code.

	@SuppressWarnings("serial")
	class TheImagePanel extends JPanel {
		public TheImagePanel() {
			setPreferredSize(new Dimension(preferredWidth, preferredHeight));
			renderedImage = new BufferedImage(preferredWidth, preferredHeight,
					BufferedImage.TYPE_USHORT_GRAY);
			Graphics2D graphics2D = renderedImage.createGraphics();
			graphics2D.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
					RenderingHints.VALUE_INTERPOLATION_BILINEAR);
			graphics2D.drawImage(biGray, 0, 0, preferredWidth, preferredHeight, null);
			graphics2D.dispose();
		}

		public void paint(Graphics g) {

			Graphics2D g2d = (Graphics2D) g;
			g2d.drawImage(renderedImage, null, 0, 0);
		}
	}
