    final Rect frame = new Rect(crop);
    final float scale = mSnapshot.getScale();

    // Rescale the frame from snapshot to window coordinate space
    frame.scale(1 / scale);

    // By default, offset it to to top/left corner
    frame.offsetTo((int) (-crop.left / scale), (int) (-crop.top / scale));

    // However, we also need to make space for the navigation bar on the left side.

            mContentInsets.left);
