Looks good! I may sign up. Interestingly, I had a brief look for open source alternatives and found that KDE Itinerary[0] may do a similar thing, and that the same code has been re-used in a Nextcloud Mail extension[1]. I don't use either so haven't been able to test directly yet.

This is generally rather computationally expensive, but I believe you are looking for potrace. Source: over 1 year ago

For fairly simple art, you could try potrace: http://potrace.sourceforge.net. Source: almost 2 years ago
