Bilinear Filter in Direct Draw?

[Gadget]

Is it possilbe to enable a bilinear filter? I want the screen to have that 'soft' edge feel to it. Or do I have to use Direct3D to do it?

Thanks

Nope, DirectDraw has no bilinear filtering, it only does some blurring while bliting when destination has diferent size than the source. As I understand you want to blur the frame buffer surface, if you want real bilinear filtering you'll have to do it by hand which would be slow, or you could blit everything to a small surface instead of the one that is displayed and then to that, but it wont look very good this way.
