Hi @nick

I just looked at your question, together with my LKEB colleague Patrick de Koning, who has experience using the SWIG Python wrapper of ITK. Unfortunately, we haven’t found the answer to your question. :slightly_frowning_face:

DetectedLines wraps a C++ reference to an std::list of LineSpatialObject pointers. I can imagine that the wrapping would have been easier if std::vector was used, instead of std::list. For example, the Python wrapper of ITK’s VectorContainer does provide full access to the underlying std::vector.

However, SWIG does support std::list so I don’t really know why it does not work: https://github.com/swig/swig/blob/rel-4.0.0/Lib/python/std_list.i

Bradley @blowekamp do you have a clue?
