Does the ".tostring()" part cost a lot of performance?
I.e. could there be more direct approaches which would be even faster?
(I remember there was some discussion on the matplotlib
mailing list concerning fast conversion of agg buffers to wx, see
http://sourceforge.net/mailarchive/message.php?msg_id=12801822
and the corresponding _wxagg.cpp
http://cvs.sourceforge.net/viewcvs.py/matplotlib/matplotlib/src/_wxagg.cpp?rev=1.1&view=auto
)
Best, Arnd
