the reference count on the numpy array passed in should have its reference count incremented so that the array will not be
deallocated when the caller deletes it
Related to the callback, in src/python/k4a/src/k4a/_bindings/k4a.py:
the declaration of the k4a_image_create_from_buffer has the incorrect callback function type (_memory_allocate_cb instead of the correct _memory_destroy_cb).
The function
create_from_ndarray()insrc/python/k4a/src/k4a/_bindings/image.pyhas a number of errors:the naming of the modules used (
_ndinstead of_np, andctypesinstead of_ctypes)when the defaults for the size of the image are used (all set to 0), the correct values are not fetched from the array.
Noneis not permitted as the callback in k4a_image_create_from_buffer(), it leads to the following error:ctypes.ArgumentError: argument 7: <class 'TypeError'>: expected CFunctionType instance instead of NoneTypethe reference count on the numpy array passed in should have its reference count incremented so that the array will not be deallocated when the caller deletes it
