Hello Nyall,
yes, content rendered to QPainter is rendered as vector object (except
images, of course). It is a big advantage - the rendering in the viewer
has two stages - in the first stage, page content is being prepared as a
vector graphics (this can be time consuming, because, for example, image
decoding and color management can take time) and then prepared pages are
rendered onto the widget (or the QPainter). So, zoom is very quick,
because I just re-render prepared vector graphics.
Best regards,
Jakub Melka

Thanks for the announcement Jakub! I had a quick look at the repo and
I'm very happy to see that your library supports rendering PDF content
directly to a QPainter. That's something I've loooong desired!
One quick question regarding this: is content rendered to QPainter
devices as vector objects? Or is the PDF content rasterised and the
drawn as images to the painter?
Kind regards,
Nyall
