[Qt-interest] pixmap.scaled gives empty pixmap

[Matthias Pospiech]

If I change in the following code the painter scale to the 
pixmap.scaled, the I get no output in my widget.

void QCameraImageBase::paintEvent(QPaintEvent * event)
{
    QPainter painter(this);
    painter.scale(scaleFracX, scaleFracY);
    //d->pixmap = d->pixmap.scaled(scaleFracX, scaleFracY, d->aspectRatio);
    painter.drawPixmap(0, 0, d->pixmap);
}

Why? I am interested in pixmap.scaled only because of the possibility to 
keep the aspect ratio, which I otherwise would have to programm on my own.
