Scale and rotate a tiff image

Question

How do you scale and rotate a tiff image without running out of memory?
I have been trying to scale the image and rotate it before i pass it to the DisplayJAI but i keep running out of memory.
code i use to rotate the image.
private Image rotateImage(boolean rotateRight)
Image img = imageHolder.getInUseImageIcon().getImage();
Image rot = null;
int imageWidth = imageHolder.getInUseImageIcon().getIconWidth();
int imageHeight = imageHolder.getInUseImageIcon().getIconHeight();
int buffer[] = new int[imageWidth * imageHeight];
int rotate[] = new int[imageWidth * imageHeight];
try
MediaTracker tracker = new MediaTracker (this);
tracker.addImage (img, 0);
tracker.waitForAll();
PixelGrabber grabber = new PixelGrabber(img, 0, 0, imageWidth, imageHeight, buffer, 0, imageWidth);
try {
grabber.grabPixels();
catch(InterruptedException e) {
e.printStackTrace();
if(rotateRight)
for(int x = 0; x < imageWidth; x++)
for(int y = 0; y < imageHeight; y++)
rotate[(x*imageHeight)+y] = buffer[((imageHeight-y-1)*imageWidth)+x];
else
for(int y = 0; y < imageHeight; y++)
for(int x = 0; x < imageWidth; x++)
buffer[(y*imageWidth)+x] = rotate[((imageWidth-x-1)*imageHeight)+y];
for(int y = 0; y < imageHeight; y++)
for(int x = 0; x < imageWidth; x++)
rotate[((imageWidth-x-1)*imageHeight)+y] = buffer[(y*imageWidth)+x];
rot = createImage(new MemoryImageSource(imageHeight, imageWidth, rotate, 0, imageHeight));
catch (Exception e)
e.printStackTrace();
return rot;
this is the code i use to scaled the image.
Image scaled = originalImage.getImage().getScaledInstance(
(int)(currentWidth * 1.5),
(int)(currentHeight * 1.5),
Image.SCALE_FAST);
I tried this method, it works and does what i want but the scrolling and loading is too slow.
public void paintComponent(Graphics g)
Graphics2D g2D = (Graphics2D)g;
g2D.rotate(Math.PI/2, (int)dimension.getWidth()/2, (int)dimension.getHeight()/2);
g2D.drawImage(image, 0,0,(int)dimension.getWidth(), (int)dimension.getHeight(), this);
Help plss.
