Hi,
I want to show a KML file as overlay on a map. Unfortunately all
examples I found have hard coded coordinates for the extend which part
of the map to show. My KML file is generated dynamically so I want to
zoom the Map to the extent of the layer.
The KML file is loaded and shown:
kml = new OpenLayers.Layer.GML("KML", "mykml.kml", {
format: OpenLayers.Format.KML,
formatOptions: {
extractAttributes: true,
extractStyles: false
},
projection: map.displayProjection
});
map.addLayer(kml);
But when i later try to zoom to the objects included in the KML, the map
does not move as expected (yes, the KML has been loaded when I call this):
map.zoomToExtent( kml.getExtent() );
The getExtent() method of OpenLayers.Layer does only return the current
viewport but not the whole extend. The following does not works neither:
map.zoomToExtent( kml.maxExtent );
I think the problem is that the KML layer may lie outside of the current
viewport and so it does not get loaded (?) I just want to get the
smallest bounding box that contains all coordinates in the KML file. How
can you do this?
Thanks!
Jakob
