[Kde-extra-gear] kgraphviewer: export to image: actual command line behind the scenes

[Kleag]

Hello,

In fact, this is not handled by dot. I just ask the scene to render itself on 
an image, this way:
    QPixmap pix(m_canvas->sceneRect().size().toSize());
    QPainter p(&pix);
    m_canvas->render( &p );
    pix.save(fn,"PNG");

So, you get the QGraphicsView antialiasing.

Regards,

Gaël
