[OpenLayers-Users] zoom level problem

[Jan H. van der Ven]

Dear maxx,

As a workaround you may try:
     var layer = new OpenLayers.Layer.Google( "Google layer", 
{'sphericalMercator':true, MIN_ZOOM_LEVEL:1, MAX_ZOOM_LEVEL:16});

You can of course also use a higher level for MIN_ZOOM_LEVEL.

Kind regards,


Jan
