{Boolean} Allow user to pan forever east/west. Default is true. Setting this to false only restricts panning if sphericalMercator is true.
clone: function()
Create a clone of this layer
{OpenLayers.Layer.Google} An exact clone of this layer
setVisibility: function( visible )
Set the visibility flag for the layer and hide/show & redraw accordingly. Fire event unless otherwise specified
Note that visibility is no longer simply whether or not the layer’s style.display is set to “block”. Now we store a ‘visibility’ state property on the layer class, this allows us to remember whether or not we desire for a layer to be visible. In the case where the map’s resolution is out of the layer’s range, this desire may be subverted.
| visible | {Boolean} Display the layer (if in range) |
moveTo: function( bounds, zoomChanged, dragging )
| bounds | {OpenLayers.Bounds} |
| zoomChanged | {Boolean} Tells when zoom has changed, as layers have to do some init work in that case. |
| dragging | {Boolean} |
removeMap: function( map )
On being removed from the map, also remove termsOfUse and poweredBy divs
| map | {OpenLayers.Map} |
getOLBoundsFromMapObjectBounds: function( moBounds )
| moBounds | {Object} |
{OpenLayers.Bounds} An OpenLayers.Bounds, translated from the passed-in MapObject Bounds. Returns null if null value is passed in.
Mixin providing functionality specific to the Google Maps API v2.
This API has been deprecated by Google. Developers are encouraged to migrate to v3 of the API; support for this is provided by OpenLayers.Layer.Google.v3
