Properties | |
isBaseLayer | {Boolean} Treat this layer as a base layer. |
singleTile | {Boolean} use tile server or request single tile image. |
Constants | |
TILE_PARAMS | {Object} Hashtable of default parameter key/value pairs for tiled layer |
SINGLE_TILE_PARAMS | {Object} Hashtable of default parameter key/value pairs for untiled layer |
Constructor | |
OpenLayers. Layer. MapGuide | Create a new Mapguide layer, either tiled or untiled. |
MapGuide OS uses a DPI value and degrees to meters conversion | factor that are different than the defaults used in OpenLayers, so these must be adjusted accordingly in your application. |
Create a new Mapguide layer, either tiled or untiled.
For tiled layers, the ‘groupName’ and ‘mapDefinition’ values must be specified as parameters in the constructor.
For untiled base layers, specify either combination of ‘mapName’ and ‘session’, or ‘mapDefinition’ and ‘locale’.
For untiled overlay layers (singleTile=true and isBaseLayer=false), mapName and session are required parameters for the Layer constructor. Also NOTE: untiled overlay layers issues a synchronous AJAX request before the image request can be issued so the users browser may lock up if the MG Web tier does not respond in a timely fashion.
factor that are different than the defaults used in OpenLayers, so these must be adjusted accordingly in your application. See the MapGuide example for how to set these values for MGOS.
