    • getRGB

      public int[] getRGB(BufferedImage image, int x, int y, int width, int height, int[] pixels)
      A convenience method for getting ARGB pixels from an image. This tries to avoid the performance penalty of BufferedImage.getRGB unmanaging the image.
      Parameters:
      image - a BufferedImage object
      x - the left edge of the pixel block
      y - the right edge of the pixel block
      width - the width of the pixel arry
      height - the height of the pixel arry
      pixels - the array to hold the returned pixels. May be null.
      Returns:
      the pixels
