No it usually won't be a closed curve, it will be a bunch of fragments of curves that come pretty close to meeting each other at their ends so generally resembling a closed curve but I'm not confident about getting an actual totally clean closed curve generated for this automatically, there will tend to be little tiny pieces and little tiny spaces between different pieces.
