is there something line BitmapToBuffer available ?

hello,

I can create a bitmap from a buffer
    bmp = wx.BitmapFromBuffer ( w, h, self.bytes )

I also can load a bitmap from a file
    bmp = wx.Bitmap("D:\\data_TO_test\\images.bmp", wx.BITMAP_TYPE_BMP)

Now I want to change a small part of the bitmap,
so is there something like BitmapToBuffer ?

In case anyone is interesting what I'm all up to,
I made a small animation of the JAL Functional Simulator I'm trying to build,
(as my first GUI Python application :wink:
see here: (600 kB)

thanks,

There probably could be, but there isn't currently. At this point you can either use the raw bitmap access mechanism to copy the pixel data yourself, or convert to a wx.Image and call its GetData().
