Yes. If you set DSCAPS_VIDEOONLY the surface is always in video memory, if you don't set either flag DirectFB can migrate the surface to/from video memory automagically. > Assuming that then, am I right in thinking that in order to write to a > secondary surface, we have to use directfbs rendering functions. No, you can render with basically anything that uses the CPU and accepts a pointer to the data and pitch. Just Lock(), render, Unlock(). -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ _______________________________________________ directfb-users mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
