[OpenLayers-Users] Zoom levels

[bradleyspencer]

Tim,

Thanks for that. It works really well.

If interested you can try my demo at
http://demo.cubewerx.com.au/DemoDrapes.html

Just enter 'harvey avenue' in address window below map. This will set bounds
to the collection of addresses geocoded from GoogleMaps.

Thanks again.

Cheers,

I am doing the same thing.  I did not see any direct support for this in
OpenLayers, so I implemented this by setting minBottom, minLeft, maxTop
maxRight variables as I loop through the icons I wish to display.  If
the lon,lats of the icon are greater/lesser than one of those variables,
I update the appropriate variable using the coordinates of the icon. At
the end of the loop, I do this:

var bounds = new OpenLayers.Bounds(minLeft,minBottom,maxRight,maxTop);
map.setCenter(bounds.getCenterLonLat(),map.getZoomForExtent(bounds));
