[matplotlib-devel] wxagg and misc wx issues

[John H. <jdh...@ac...>]

I just committed a wxagg backend.  Jeremy and others may want to give
it a test drive.  I use fromstring / tostring methods to transfer the
image data to the wx bitmap.  This has the advantage of requiring no
wx specific extension code but obviously implies a performance hit.

This is just a first pass implementation so I tried to keep the
framework as close to the current wx setup as possible, in order to
reuse as much of backend_wx as possible.  I think though that the
bitmap is not necessary since I am rendering to agg.  Jeremy, can we
transfer the wxImage created in FigureCanvasWXAgg.draw directly to the
DC w/o going through the bitmap?

On my system, however, the performance is quite good.  Even when/if we
have an extension solution in place, it will be nice to preserve the
string methods as a fallback for those who can't compile the extension
for some reason.

There are a couple of unrelated wx issues that need attention:

  * The toolbar seems not to work on Mac OS X, either for wx or
    wxagg.  Not sure why.  It doesn't even showup in the window

  * I got this email this morning

        Hi, This is to inform you that Matplotlib 0.52 does not work
        with wxpython 2.5.1.  The corresponding code is available
        below.

        It works correctly with the previous version 2.4 of wxpython.

That's all for now,
