I see. Thanks for clarifying this. And yes, I think this should be fixed.
Hmm, it seems that somehow pil_to_array tries to make the image
upside-down by itself.
x_str = im.tostring('raw',im.mode,0,-1)
However. I'm afraid that changing this behavior may not be ideal for
backward-compatibility.
I think one possible solution would be to simply deprecate the support
for PIL image in imshow, and let users explicitly use array-interface
via asarray function.
Is there any other idea?
I'll make this change unless someone come up with something.
