if (framingRect == null) {

        int screeny = screenResolution.y;
        int width, height, left, top;
        if (screenx > screeny) {
            width = (int) (screenx * 12.5 / 100);
            height = (int) (screeny * 25 / 100);
            left = (int) screenx * 83 / 100;
            top = (int) screeny * 75 / 100;
        } else {
            left = (int) (screenx * 12.5 / 100);
            top = (int) (screeny * 25 / 100);
            width = (int) screenx * 83 / 100;
            height = (int) screeny * 75 / 100;
        }
  framingRect = new Rect(left,top, width, height);

  Log.d(TAG, "Calculated framing rect: " + framingRect);
}
return framingRect;
}
