Is something (hardware, drivers) capable of doing that?
Any hardware with a decent texture unit (or scaler which writes the results to the framebuffer) should be enough. Also some hardware has video overlays which can do it too (OMAP3 is one example). I don't know if any Xorg driver can do it, but DirectFB's matrox driver supports field based scaling. It uses the texture unit. > It would mostly make sense with small reduction (like 576->480), right? The scaling ratio should be irrelevant. The fields are basically independent pictures so you can scale them how much you like. -- Ville Syrjälä [email protected] http://www.sci.fi/~syrjala/ _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
