Re: [Matplotlib-users] How to determine position of axes after imshow?

[Mark B. <ma...@gm...>]

I tried a few things and found out that doing a pause works.
So why does a pause work, but a draw() or show() does not?
This all on Windows using the standard PythonXY installation.
Here is the code that works (testimage.py):

from pylab import *
c = ones((10,20))
ax = imshow(c)
pause(0.01)
print ax.get_axes().get_position()

Running from IPython:
run testimage
Bbox(array([[ 0.125     ,  0.24166667],
       [ 0.9       ,  0.75833333]]))
