Get size of BorderLayout.CENTER

Question

I have a gif that's set to the center of a Panel using BorderLayout.
        pic = new ImageIcon(gifName);
        image = pic.getImage();
        imageWidth = image.getWidth(null);
        imageHeight = image.getHeight(null);
        label = new JLabel(){
                    public void paintComponent(Graphics g){
                        super.paintComponent(g);
                        double width = getWidth();
                        double height = getHeight();
                        Insets insets = getInsets();
                        int hInsets = insets.left + insets.right;
                        int vInsets = insets.top + insets.bottom;
                        // scale up to full image size
                        double wScale = width/(imageWidth + hInsets);
                        double hScale = height/(imageHeight + vInsets);
                        double scale = (wScale > hScale ? wScale < 1 ? wScale : 1 : hScale < 1 ? hScale : 1);
                        g.drawImage(image, 0, 0, (int)(imageWidth * scale), (int)(imageHeight * scale), this);
        };the gif scales dynamically with the size of the frame, the problem is that the gif would be fully visible if it were just added to the contentPane of the frame, but it's added to the CENTER. to the SOUTH i have a 3 x 2 GridLayout of TextFields, and this "covers up" the bottom of the gif. how do i set the gif to only extend to the bottom of the CENTER portion of the panel, instead of the bottom of the frame it is in?

Answer 1

Ok, i got everything displaying now, but i still have the residual problem that when i open an internal frame with a circle in it, and then open an internal frame with a rectangle in it--the circle becomes stretched horizontally. to explain via an example:
-- i open a circle image that is inscribed within a 10 x 10 internal frame. the circle fills up the frame.
-- i then open a rectangle image that is inscribed in a 20 x 10 internal frame. the image of the circle now takes on the width:height ratio of the rectangle. furthermore, when i initially open these images, they are displayed at 1/2 the dimensions of the actual .GIF file, but after opening this second frame, the first one (after i resize a little to update the image) takes on the max size of the most recently opened one (rectangle in this case).
So my circle image is 600 x 600. i open it--it displays as 300 x 300. my rectangle image is 487 x 265. i open it and it displays at ~244 x 133 simultaneously my circle image now looks like an oval. i try to resize it and it jumps to 487 x 265. the reverse occurs if i open the rectangle first, then open the circlei.e. the rectangle assumes the size of the circle, and becomes a square. How do I fix this?
        toolPanel.setSize(new Dimension((int)(imageWidth*.5), (int)(imageHeight*.5)));    
        System.out.println("tool size--w x h: "+toolPanel.getWidth() + " "+toolPanel.getHeight());

        //Set the window's location.
        setLocation(xOffset*openFrameCount, yOffset*openFrameCount); //changes location for each new JIF
        //scroll.setViewportView(label);
        toolPanel.add(label, BorderLayout.CENTER);
        toolPanel.add(myPanel, BorderLayout.SOUTH);       
        toolPanel.setOpaque(false); //works
        contentPane.add(toolPanel);
