<p>Deyan,</p>
<p>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.</p>

<div>Hello,</div>
<div>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.</div>
<div><br>
</div>
<div>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.<br>
</div>
<div><br>
</div>
<div>Can you please share if there is a way to request specific
zoom-levels without doing the closing/reopening stuff?<br>
</div>
