Signature

def _validate_connectivity ( image_dim , connectivity , offset )

Convert any valid connectivity to a footprint and offset.

image_dim : int: The number of dimensions of the input image.
connectivity : int, array, or None: The neighborhood connectivity. An integer is interpreted as in scipy.ndimage.generate_binary_structure, as the maximum number of orthogonal steps to reach a neighbor. An array is directly interpreted as a footprint and its shape is validated against the input image shape. None is interpreted as a connectivity of 1.
offset : tuple of int, or None: The coordinates of the center of the footprint.

c_connectivity : array of bool: The footprint (structuring element) corresponding to the input connectivity.
offset : array of int: The offset corresponding to the center of the footprint.

: ValueError:: If the image dimension and the connectivity or offset dimensions don't match.
