How to send cropped image through msgbroker using python

Hey, I am also trying to use custom objects in pyds. I asked here. I understand now, that I have to add the classes in Cpp (did that already for the C Version of my project). How can I now re-generate the pyds binding with the added object classes? It does not seem like the pyds bindings are open-source as it only comes as a precompiled .so file?
