Problem z rotacją obrazka(QPixmap) [Qt]

void PaintArea::paintEvent( QPaintEvent * e )
{
    QPainter painter( this );
    painter.translate(( - HH.pixPlane.width() / 2 + 1 ), -( HH.pixPlane.height() / 2 + 1 ) );
    QMatrix mat = QMatrix().rotate( HH.angle );
    painter.setMatrix( mat );
    painter.drawPixmap( HH.XY.x(), HH.XY.y(), HH.pixPlane.width(), HH.pixPlane.height(), HH.pixPlane );
}

painter.translate( xc, yc );
painter.rotate( 45 );

void PaintArea::paintEvent( QPaintEvent * e )
{
    QPainter painter( this );
    painter.translate( width() / 2, height() / 2 );
    painter.rotate( HH.angle );
    painter.drawPixmap( - HH.pixPlane.width() / 2, - HH.pixPlane.height() / 2, HH.pixPlane.width(), HH.pixPlane.height(), HH.pixPlane );
}
