Like there is an example for letter S and a path for it looks like next:

var letterPath = new Path(
new Segment(new Point(63.39306640625, 265.7138671875), null, new Point(10.86669921875, 6.96630859375)),
new Segment(new Point(106.58203125, 277.97412109375), new Point(-16.71826171875, 0), new Point(24.79931640625, 0)),
new Segment(new Point(145.87060546875, 245.9306640625), new Point(0, 18.947265625), new Point(0, -17.27587890625)),

So now my question is how do u convert a svg file produced for example by Inkspace into Paper path?

Here is an example what I am trying to convert from:

<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
