[Matplotlib-users] Converting figure to numpy array

Hi,

I want to convert the current figure to a numpy array w/o saving the
image to disk. I need this to convert a matlab function to python, the
original code is:
F = getframe(gcf);
X = frame2im(F);

My current workaround is
h = gcf()
h.savefig('tmp.png')
X = imread('tmp.png')
which is obviously not viable. Also I cannot use a different backend.
TkAgg seems to be the only backend running smoothly with ipython on my
machine.
I tried several functions but I couldn't find the right one. I'm using
matplotlib 0.98.6svn and TkAgg as backend.

Someone knows how to do this neatly?

Cheers

Philipp
