Hi Paolo,
My initial question was concerning a custom map type, not a derived
plugin. So basically you are saying that on a retina x2 screen I can
send back 512x512 tiles and the plugin will mark the tile with
pixelRatio = 2 (i.e not just rescale it) ?
But in fact I would prefer to be able to create my own plugin, because
the charts I am using are just local (some of them drawn on the fly,
some of them stored in mbtiles, some of them encrypted, and potentially
I also need vector tiles). For the time being I create a thread for each
type of map which is also a QTcpServer, but I would prefer to be able to
communicate directly and control more things at the plugin level. I will
investigate all this once more.
Thanks again for you replies
Philippe.

I may have misunderstood what you meant with "custom osm plugin".
What does that mean?
If you meant "a modified osm plugin", then you would be already using
this class anyway.
If you meant "custom map type", then just feeding 512x512 tiles should
work.

Hi,
Seems to me that QGeoCameraCapabilities is a private qt API?
From what I found on the net seems it would help a lot for customizing
own map plugin or tile server, but it's not clear how I can access it.
