{OpenLayers.Projection} Requires proj4js support. Projection used when creating the coordinates in the link. This will reproject the map coordinates into display coordinates. If you are using this functionality, the permalink which is last added to the map will determine the coordinate type which is read from the URL, which means you should not add permalinks with different displayProjections to the same map.
createParams: function( center, zoom, layers )
Creates the parameters that need to be encoded into the permalink url.
| center | {OpenLayers.LonLat} center to encode in the permalink. Defaults to the current map center. |
| zoom | {Integer} zoom level to encode in the permalink. Defaults to the current map zoom level. |
| layers | {Array(OpenLayers.Layer)} layers to encode in the permalink. Defaults to the current map layers. |
{Object} Hash of parameters that will be url-encoded into the permalink.
destroy: function()
Set the map property for the control.
