Hi,

maybe I am missing out something... here's my use case and I can't see
how I would achieve that:

Say I have a layer's surface, containing a scene rendered with the
width/height of the layer and the scene is currently visible, i.e. in
the front buffer.

Now I want to change the layer's width & height and redraw my scene in
the new resolution. Once redrawn, I want that surface to be the contents
of the layer.

I.e. let's say my output is 1920x1080, the current layer surface's front
buffer is 720x576 (stretched by the hardware/mixer to match the output
resolution) and the layer surface's back buffer 1280x720; then I want to
do a flip and also the flip shouldn't cause any visible glitches.
Obviously this is not possible the way I described it, so how would one
do that with DirectFB?

Of course I could render into an additional surface and stretchblit
things, but I want to avoid additional blitting... Also, doing it like
this will still give a visible glitch on screen while reconfiguring the
layer.

Hope my description is somewhat clear :-)


Cheers,
Andre'
