Working with the class mvIMPACT.acquire.PropertyPtr ( mvIMPACT::acquire::PropertyPtr in C++) is of limited use only: The returned values reference native memory addresses so most likely cannot be worked with in the target language. They might however be fed back into another (finally native) function expecting this address.
The file stream classes from the GenICam namespace of the C++ interface (e.g. mvIMPACT::acquire::GenICam::IDevFileStream and mvIMPACT::acquire::GenICam::ODevFileStream) are currently not available in Python.
The classes from the namespace mvIMPACT::acquire::GenICam::labs (e.g. mvIMPACT::acquire::GenICam::labs::LensControlBase and mvIMPACT::acquire::GenICam::labs::LensControlBirger) as well as the classes from the C++ header file mvIMPACT_acquire_helper.h are currently not available in Python.
