How to resample a ofxSVG or ofPath

I am trying create ofMesh from a svg file. This basically works fine, but i need more points on the outline, so i am looking for a way to resample the path.

This is where i am with out any resampling:

    svg.load("file.svg");

    path = svg.getPaths()[0];
    mesh = path.getTessellation();

I found out that it is possible to resample ofPolyline with getResampledBySpacing(5). But i can’t figure out how to convert the ofPolyline back in to a path.

Any help would be much appreciated.

if you have a closed polyline you can convert to a path (for tessellation) like this:

ofPath p
for (int i = 0; i < line.size(); i++){
  if (i == 0) p.moveTo(line[i]);
  else p.lineTo(line[i]);
}
p.close();

Thank you @zach, worked beautifully!

// ofApp.h

   ofxSVG svg;
   ofPath path;
   ofPath pathResampled;
   ofMesh mesh;

// ofApp.cpp

   svg.load("letter_B.svg");    
   path = svg.getPaths()[0];
    
   for (int i = 0; i < path.getOutline().size(); i++) {
       ofPolyline outline = path.getOutline()[i].getResampledBySpacing(5);
        
       for (int j = 0; j < outline.getVertices().size(); j++){
           if (j == 0) pathResampled.moveTo(outline[j]);
           else pathResampled.lineTo(outline[j]);
       }

       pathResampled.close();
   }
        
   mesh = pathResampled.getTessellation();
