[Matplotlib-users] image display conventions

[Perry G. <pe...@st...>]

I'm wondering about whether the convention that matplotlib 
adopts for image display is the the standard expected for
science and engineering. When an image is displayed,
index 0,0 appears at the top left. While that is the standard
conventions for most computer graphics, it isn't in astronomy 
(we usually expect it to be bottom left). Are there others
that expect the way it behaves now? 

While I'm at it, does anyone else need to display images as
raw pixel dumps (every pixel in the image matches the
display pixel) without trying to match axes? This is very
common in astronomy (I understand that this is effectively
not really using matplotlib to do graphics, but rather as
a simple image display window, but this is something
astronomers are used to doing for data inspection, and
it would be nice to be able to do this within matplotlib as it
is for IDL). My guess is that a raw image display function
would be figure-oriented (as opposed to axes-oriented as it
is for the current one).
