PShape will load an SVG for display, but afaik it doesn't give you access to any of its attributes.

good luck!

Couple of years ago, I made a script in AppleScript (so that work on Mac only). This will create a custom function that you can paste in Processing. Exact reproduction of your vector path drawing and the possibility to still affect some control points with interactive behavior.

Open Illustrator. Draw something with the pen. Make sure that your path is activated (all point along the path are selected). Open the applescript routine in AppleScript Editor and run it. It will automatically insert in your pasteboard the code that you can paste in Processing. Just call this function with the required arguments in Processing and voilà.

One precision. It is not working with compound path figures, which is the case of a lot of letters (like an O).
