[wxPython-users] Re: Trouble with drawing, I need some ideas :)

[Peter Damoc]

Hi Robin,
First, let me apologize for not being clear again. :)

I appreciate the advice you gave BUT it is not touching the real issue.
The sample created was just some boiler plate for people to play with. It
was not "efficient".
I can do all the buffering that could be done BUT my main issue remains the
same:

How do I use alpha in a buffer that need to be blited over some other
drawing? Color based transparency won't do because of the wxGCDC used in the
buffer.

Here... take a look at this kind of desperate code:

        cache =3D wx.MemoryDC(wx.EmptyBitmap(w,h))
        cache.SetBackground(wx.TRANSPARENT_BRUSH)
        cache.SetBackgroundMode(wx.TRANSPARENT)
        cache.Clear()
        gc_cache  =3D wx.GCDC(cache)
        gc_cache.SetBackground(wx.TRANSPARENT_BRUSH)
        gc_cache.SetBackgroundMode(wx.TRANSPARENT)
        gc_cache.Clear()

Maybe it expresses what I'm trying to accomplish.

Peter.
