    Either `size` or `footprint` must be defined. `size` gives

    position, to define the input to the filter function.
    `footprint` is a boolean array that specifies (implicitly) a
    shape, but also which of the elements within this shape will get
    passed to the filter function. Thus ``size=(n,m)`` is equivalent
    to ``footprint=np.ones((n,m))``.  We adjust `size` to the number
    of dimensions of the input array, so that, if the input array is

        The input is extended by reflecting about the edge of the last
        pixel. This mode is also sometimes referred to as half-sample
