[wxPython-users] using wxImage in C++ python extension

[Christopher Barker]

Robin,

Sorry to keep peppering you with little messages about this, but...

A couple months ago, you mentioned that you were trying to see if you 
could expose some of the methods for manipulating wx.Bitmap data 
directly. This would be a great application of that -- if we could just 
pass a pointer from the Agg buffer straight into a wxBitmap, then there 
would be no overhead at all. Of course, that would only work if the data 
format was right, but if we're lucky, that might be the common use case.

Also, it would be great if that could also be accomplished through the 
numpy array interface. Travis recently donated a patch to PIL that does 
this:

I imagine the code for wxBitmap and wxImage would look similar.

I'd like to get the array interface to be accepted by PointListHelper 
and friends too. I have it in mind to write that code, but who knows 
when I can get to it.

-Chris
