Ex9 blob to svg polyline

Hi vvvv fellows,
I would like to translate a blob edges in ex9 into svg polyline or line/b-spline.
Tried pipet, but got weard forms. Attached here that test.
Quiet sure it is whishfull thinking, but would be happy if anyone has an idea how to make it.

have a look at Contour node and it’s help patch- pretty sure that’s what you are after

great, thanks everyoneishappy! you solved the riddle.
it’s working quiet nice. still the line is not consistent for some reason, but sure this is the direction.
