Hi<br>
<br>
I am using OSM and connecting successfully to their mapnik server.<br>
Everything works OK, this is my code: <br>
<br>
map = new OpenLayers.Map
("map", {<br>
controls:[<br>
new OpenLayers.Control.Permalink(),<br>
new OpenLayers.Control.MouseDefaults (),<br>
new OpenLayers.Control.LayerSwitcher(),<br>
new OpenLayers.Control.MousePosition(),<br>
new OpenLayers.Control.PanZoomBar()], <br>
maxExtent: new<br>
OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34),<br>
numZoomLevels:17,<br>
maxResolution:156543,<br>
units:'meters', <br>
projection:
"EPSG:41001"} );<br>
<br>
layerMapnik = new OpenLayers.Layer.TMS(<br>
"Mapnik (updated
weekly)",<br>
"<a
href="http://tile.openstreetmap.org/mapnik/" target="_blank">
http://tile.openstreetmap.org/mapnik/</a>",<br>
{type:'png', getURL:
get_osm_url, displayOutsideMaxExtent: true },<br>
{'buffer':1} );<br>
<br>
etc. etc.<br>
<br>
What I am not understanding is how to limit the zoom levels to just from <br>
zoom 9 to zoom 16 I tried different ways: An array of scales, an array of<br>
resolutions, changing the maxResolution, change the numZoomLevels etc etc<br>
always failed, is there someone in the list who can help with this issue? <br>
<br>
Kind Regards<br>
Rosario Carbone<br>
