If you're just looking for the dimensions of the overall figure in pixels,
you can easily access them through other means. E.g:
import matplotlib.pyplot as plt
fig = plt.figure()
_, _, width, height = fig.bbox.extents # <- Extent of the figure in pixels
fig.savefig('temp.png', dpi=fig.dpi) # <- Be sure to specify the dpi!!
Note that you'll have to specify that you want to save the figure at the
same DPI it was when you called the extents...
The figure will be saved with whatever default DPI is in your .matplotlibrc,
which is commonly different than the default screen dpi (80).
Hope that helps,

Start uncovering the many advantages of virtual appliances
and start using them to simplify application deployment and
accelerate your shift to cloud computing.
