void extractFromPixeldata(short[] pixeldata, int columns, int stride, int mask, byte[] ovlyData, int off, int length)
extract From Pixeldata

 & img.getRGB((int) (Math.random() * img.getWidth()), (int) (Math.random() * img.getHeight()))));

Image imageFromIntArray(int[] pixels, int w, int h)
Build an image from a pixel array.

Image img = Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(w, h, pixels, 0, w));
return img;

int[] pixels(BufferedImage image)
pixels

return image.getRGB(0, 0, image.getWidth(), image.getHeight(), null, 0, image.getWidth());

 image.getRaster().setDataElements(x, y, width, height, pixels);
else
 image.setRGB(x, y, width, height, pixels, 0, width);
