<span class="gmail_quote"></span>Hi all,<br><br>I'm currently trying to get the co-ordinates of the origin of the map in order to utilise the geoserver meta tiler extension to WMS see: <a href="http://docs.codehaus.org/display/GEOSDOC/WMS+vendor+parameters" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://docs.codehaus.org/display/GEOSDOC/WMS+vendor+parameters</a> These co-ordinates must be included in the WMS URL so I'm doing the following:<br><br>...<br><span>var map;<br>function init()
<br>{<br>var options =
{resolutions:[72,36,18,9.6,4.8,2.4,1.2,0.6,0.3,0.15,0.125],maxExtent:new OpenLayers.Bounds(0,0,2000000,2000000),maxResolution:'auto',units:'meters',projection:'EPSG:27700',controls:[]};<br>map
= new OpenLayers.Map( $('map'), options );<br>map.setCenter(new
OpenLayers.LonLat(543443,255213), 7);<br>var olextent = map.getExtent();<br>var
origincoords=toString(olextent.bottom) + ',' + toString(olextent.left);<br>...<br><br>and I'm getting the following error:</span><br><br><span><div>maxExtent has no properties</div><div><div><a>
