I think it supports NPOT, but the precision of the scaling factor is too poor (5 fractional bits). Clipping is also a bit broken in HW. This is with the 2D core. We haven't started using the 3D core directly. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-users mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
