SVG to alpha channel QPixmaps?

I have an image in *.svg format. I want to load and convert it into a QPixmap object, where the image is opaque where the svg vector lines dictate color, and transparent everwhere else.

I'm currently doing this:

Code:

---

QSvgRenderer renderer;
renderer.load("images/my-logo.svg");
QPixmap image(renderer.defaultSize());
QPainter painter(&image);
renderer.render(&painter);
QLabel *logoLabel = new QLabel(this);
logoLabel->setPixmap(image);

---

It puts the svg image into the QLabel, but with an opaque background.
How can I make it with a transparent background?

I am not sure if the svg renderer can handle that.
Are you sure the pixmap is not transparent?
Have you tried saving it and opening it in a viewer or something?

Try:

Code:

---

image.fill(Qt::transparent);

Are you sure the renderer won't overwrite all the pixels in the pixmap?

Yes, I tested it. :)
