Parameters
----------
fname : str or file
File name or file-like object.
arr : ndarray
The array to write.
kwargs : keyword pairs, optional
Additional keyword arguments to pass through (see ``tifffile``'s
``imwrite`` function).
Notes
-----
Provided by the tifffile library [1]_, and supports many
advanced image types including multi-page and floating-point.
This implementation will set ``photometric='RGB'`` when writing if the first
or last axis of `arr` has length 3 or 4. To override this, explicitly
pass the ``photometric`` kwarg.
This implementation will set ``planarconfig='SEPARATE'`` when writing if the
first axis of arr has length 3 or 4. To override this, explicitly
specify the ``planarconfig`` kwarg.
