Phase 7: Zero-copy numpy array via capsule ownership#8
Merged
Conversation
…transfer Add imagedata_to_numpy_zerocopy() that transfers ImageData ownership to a Python capsule instead of copying pixel data. When a transform produces an output ImageData, the numpy array now directly references the existing buffer with the capsule preventing premature deallocation. Used in Transform.apply() binding — eliminates one memcpy per transform call from Python. The existing imagedata_to_numpy() is kept for cases where the source must outlive the array.
