ITK package requires numpy array be of order='C' before using ITK.GetImageFromArray #1243

Regarding the conversion of Numpy arrays to ITK Images, I have found that an ITK package will report an error if the numpy array is not of order type 'C'. Specifically, when using an ITK Image that has been created from the conversion of a numpy array with itk.CoocurrenceTextureFeaturesImageFilter(), I will get the following error:

Requested region is (at least partially) outside the largest possible region.

Changing the numpy array to order 'C' resolved this issue. This doesn't seem to happen with arbitrarily created arrays using, for example, np.random.rand(), but does happen in my case with a pre-processed image.

Expected information

The proper format for a numpy array before conversion to ITKImage type.
