Hello,
I've been trying for a few days now to send the pixel data of a surface using get_view() through a pipe to a c progam.
But i can't get the raw values of the rgb pixels using BufferProxy.raw...
I can see the "start" and "end" but not the "buf.raw".
I'm using python 2.7.
i tried using "array = pygame.surfarray.pixels3d(screen)", i can see it when using "print array" but the data can't go through the pipe because it is not contiguous.
Do you have any idea where i went wrong ?
Thanks !
