Re: [matplotlib-devel] Transparent backgrounds for savefig

[Michael D. <md...@st...>]

Something similar was added to SVN yesterday.  Pass "transparent=True" 
to savefig.  This will set both the figure rectangle and the axes 
rectangles to transparent.

If you just want a transparent figure rectangle, you can do:

  fig().figurePatch.set_alpha(0.0)

Maybe this should be made an option on the "transparent" kwarg to 
savefig, something like:

   transparent = 'figure' | 'figure_and_axes'

Or is that just making things too complicated?

Cheers,
Mike
