QSvgRenderer - correct rendering of svg-items despite of defaultSize()?

That is how i try to render SVG:

void DialogImageProperies::showSVG(QString sFile){
    this->adjustSize();

    QSvgRenderer rndr(sFile);   
    QPixmap px;
    QSizeF szSvgF = rndr.defaultSize();

    if (szSvgF.width() > szSvgF.height())
    {
        px = QPixmap(1000, int(qreal(1000 )* szSvgF.height()/szSvgF.width()));
    }
    else
    {
        px = QPixmap(int(qreal(1000 )* szSvgF.width()/szSvgF.height()), 1000 );
    }


    QPainter p(&px);
    rndr.render(&p);

    ui->wdgBck->setPixmap(px);
    this->exec();
}

But as for me, i never notice what is a size of canvas in any created by myself vector-image. So, i think that users also will not predefine correct boundaries.

That is how SVG looks in Inkscape - Inkscape That is what i get - rendered

For now i see no way to workaround all it...

If manually delete width="1250" and height="961.25" then Qt recalculate real itemsBoundingRect of svg)))
