Deyan,
you generally don't need to use that option. The driver should
automatically select the right overview level when you use the dataset
or band RasterIO() methods, according to the window of interest and the
size of the buffer you specify.

Hello,
I am trying to handle map zooming in a GDAL-based MBTiles windows app.
The only way I have found to control the raster's zoom level is
through GDALOpenEx's open options.
Changing the zoom-level app-side would require closing the MBTiles db
and reopening it, passing the new zoom level as an open option. I made
this to work but it seems to me somehow clumsy as there is surely a
significant overhead for closing and reopening the db.
Can you please share if there is a way to request specific zoom-levels
without doing the closing/reopening stuff?
