Hoiw to create a thumbnail image which doesnt refer to the original

Question

I have a large buffered Image, I want to create a smaller version of the image and then release the memory taken up by the larger image
Image smallImage = largeImage.getScaledInstance(size,size,Image.SCALE_FAST);This creates a small image but I think it is just a view over the larger image, how can I create it as standalone so I can release the memory used in the large image.

Answer 1

Yes thats done the trick, code as follows:
private static Image resize2D(Image srcImage, int size)
        int w = srcImage.getWidth(null);
        int h = srcImage.getHeight(null);
        // Determine the scaling required to get desired result.
        float scaleW = (float)size / (float)w;
        float scaleH = (float)size / (float)h;
        System.out.println("Image Resizing to size:"+size+"w:"+w +":h:"+h+"scaleW:"+scaleW+"scaleH"+scaleH);
        // Create an image buffer in which to paint on.
        BufferedImage bi = new BufferedImage(size,size,BufferedImage.TYPE_INT_ARGB);
        // Set the scale.
        AffineTransform tx = new AffineTransform();
        tx.scale(scaleW, scaleH);
        // Paint image.
        Graphics2D g2d = bi.createGraphics();
        g2d.drawImage(srcImage, tx, null);
        g2d.dispose();
        return bi;
BufferedImage newImage = resize2D(origImage, 200);
origImage.flush();
origImage=null;
