BufferedImagetoBufferedImage(Image image, int type)
Create a BufferedImage from the given image 
int w = image.getWidth(null);
int h = image.getHeight(null);
BufferedImage bImage = new BufferedImage(w, h, type);

BufferedImagetoBufferedImage(Image image, int x, int y)
Converts the given Image into a BufferedImage . 
BufferedImage result = new BufferedImage(image.getWidth(null), image.getHeight(null),
        BufferedImage.TYPE_INT_ARGB);
Graphics g = result.getGraphics();
try {
    g.drawImage(image, x, y, null);
    return result;
} finally {
    g.dispose();
