Why to invert the order of the indices between numpy and SimpleITK?

Question: if GetArrayFromImage is not making a copy… Does that mean that any changes in the data contained by the numpy array, will also be shared if I query the image directly with GetPixel or similar methods?

GetArrayFromImage makes a deep copy, but GetArrayViewFromImage is a read only buffer in numpy. With the view you must maintain a ssitk::Image copy and if you modify the image it could effect the bumpy buffer. There is also SimpleITK’s lazy copying and reference accounting which can affect which image the buffer points to.
