I will add, in fairness to all concerned, that MATLAB has the same issue 
as matplotlib with respect to image position readout.  If one uses 
MATLAB's ginput() to read pixel coordinates from a displayed image, they 
have to be reversed to address the corresponding data in the displayed 
array.  Maybe the fairest thing is to tell me "this is how it works, get 
over it" :-) and move on.
