Yes, it makes the image the right way around.  I was simply confused 
because I expected the pixel at (x,y) in the imshow display to be the 
value of img[x,y].  It appears not to be.  I hasten to add MATLAB's 
worse, as the pixel at (x,y) is actually the value of img[y,x];  MATLAB 
displays with the first array coordinate increasing downward and the 
second from left to right.

I'm sure the code is fine, John, and it's just me.  Specifically, if I 
want to see how matplotlib is doing something, I can't just trace 
function calls like I'm used to doing with Fortran and C, because there 
are methods too and I have to find the class which defines those methods 
to see what's happening.  Is there anything like ctags for Python?
