        {
            int length = 4 * rect.Width;

            byte[] buffer = new byte[length];
            for (int index = 0; index < rect.Height; ++index)
            {
                int offset = (rect.Top + index) * this._stride + 4 * rect.Left;
                Animator.CopyToBitmap(buffer, this._bitmap, offset, length);
            }
