Help!

The method below rescales an image, its basically copied from sun's site (but with a few modifications) ..... it doesn't quite work right though, most of the time it dumps a REALLY long exception stack trace when I try and use it.

//Rescales an image to the specified dimensions
public static Image rescaleImage(Image imageSource, int width, int height) {
//Get Scale Factors
double wScale=(double)width/(double)imageSource.getWidth(null);
double hScale=(double)height/(double)imageSource.getHeight(null);
//Get closets integer scale dimensions
int wScaled=(int)(wScale*imageSource.getWidth(null));
int hScaled=(int)(hScale*imageSource.getHeight(null));
//Create a Buffered Image with our Scale
BufferedImage imageOut = new BufferedImage(wScaled, hScaled, BufferedImage.TYPE_INT_RGB);
//Setup Scaling Transformation
AffineTransform tx = new AffineTransform();
tx.scale(wScale, hScale);
//Create Graphics2D object and render the new image
Graphics2D g2d = imageOut.createGraphics(); //Graphics2D now holds empty buffered pallet
//g2d.setRenderingHints((RenderingHints)hints); //set the rendering hints
g2d.drawImage(imageSource, tx, null); //Render image onto our pallet with approiate scaling
g2d.dispose(); //Clear some memory
return (Image)imageOut; //Return our newly rescaled image
}

Here is the tack dump:

It seems you're passing a negative size to the BufferedImage constructor.
