I guess you can do it by restricting transform.ScaleX and transform.ScaleY in the below event handler.if initialScale < somelength ,then only do the code.

private void OnPinchDelta(object sender, PinchGestureEventArgs e)
    {
        transform.Rotation = initialAngle + e.TotalAngleDelta;
        transform.ScaleX = initialScale * e.DistanceRatio;
        transform.ScaleY = initialScale * e.DistanceRatio;
    }
