Just getting back to work after an illness...
Eric's assessment is 100% correct: the transform kwarg is ignored by
images. It probably could be, but it would not be trivial, particularly
in the way the Agg backend is currently architected. This should
probably be added as a feature request to

Thanks to both of you for your help! I had spotted the transform
argument in imshow, but didn't manage to find any information about
how to use it. The Affine2D method looks like it will help, so I
should be all set now.
Thanks!

It looks like rotation/translation should be easy to do with Affine2D,
so I tried using it, but I can't seem to get it to work as expected -
here is an example of how I am using it:
import numpy as np
from matplotlib.pyplot import *
from matplotlib.transforms import Affine2D
im = np.random.ra

Hello,
I was wondering whether there is a way to rotate a grayscale/
colorscale when using imshow.
I have been using PGPLOT (a fortran/c plotting library) for many years
now, and the equivalent to imshow is called PGGRAY (or PGIMAG). One of
the arguments this function takes is a 6-element ar
