I want to use bitBlt in Qt4,but I find it deleted by "#ifdef QT3_SUPPORT" by default.

Is it replaced by RaW bitmap operation with the same efficiency.??

Thanks.

QPainter::drawPixmap is the suggested alternative. It should be the same speed when there is no rotation matrix or similar that alters the image before blitting.
