Rotating an image and getting back the image...

Question

Hi,
I have a small problem using images...
1. I have an existing image...
2. I need to rotate the image by a certain angle(say 60 degree)....
3. Return the rotated image back to the calling routine...
My problem is that I can rotate the image using the AffineTransform, and draw the image immediately... but I cannot return the rotated image... can anyone help me out on this??????

No sorry that didn't fix it. I forgot to mention that I already have a method in ImagePanel called clearImage()
     * Clear the image on this panel.
    public void clearImage()
        if(panelImage != null) {
            Graphics imageGraphics = panelImage.getGraphics();
            imageGraphics.setColor(Color.LIGHT_GRAY);
            imageGraphics.fillRect(0, 0, width, height);
            repaint();
    }But if I clear the panel and then try to apply the function nothing happens. The LIGHT_GRAY background remains.
This is how I apply a function in the class[b] ImageViewer
     * Apply a given function to the current image
    private void applyFunction(Function function)
         if(currentImage != null) {     
              if(function.getName().equals("Zoom In")) {
                   Zoom.ZOOMIN_RATE = 1.5;
                   function.apply(currentImage);
              else if(function.getName().equals("Zoom Out")) {
                   Zoom.ZOOMIN_RATE = 0.5;
                   function.apply(currentImage);
              else {          
                   imagePanel.clearImage();
                   function.apply(currentImage);    //A function is applied                   
              frame.repaint();              
              showStatus("Applied: " + function.getName());
         else {
              showStatus("No image loaded.");
    }
