<p class="MsoNormal" style="margin-left:35.4pt">Hi<br>
<br>
Possibly related.<br>
<br>
Using the default style and default zoom levels, zooming out to display<br>
the whole of the UK took an age on my old device - the amount of detail<br>
in each tile at the outermost map is vastly more that the pixels<br>
available. Leaving it for a few minutes to draw everything just results<br>
in an unreadable mess. I guess it also uses a lot of the device memory<br>
to display so many tiles at the the same time.<br>
<br>
What I now have is an extra outer level that is a bit like the overview<br>
map, just shows sea/land, some borders, motorways and trunk roads and<br>
major cities. <br>
<br>
I have this in the mystyle/options:<br>
levels = 0:24, 1:22, 2:20, 3:18, 4:15<br>
<br>
but command line option --levels="0:24,1:22,2:20,3:18,4:15" should<br>
override the specification in the style.<br>
<br>
Beware, adding an extra map level might make the map exceed 2G <br>
