Inherits MgResource.
Detailed Description
Defines the runtime state of a map.
- Note:
- This is a base class. In most cases it is best to use a class derived from this class. See Maps and Layers for details.
Public Member Functions | |
| virtual void | Create (CREFSTRING mapSRS, MgEnvelope *mapExtent, CREFSTRING mapName) |
| Initializes a new MgMapBase object given a spatial reference system, spatial extent of the map, and a name for the map. This method is used for the WMS service implementation and creates a map without any layers. | |
| virtual void | Create (MgResourceService *resourceService, MgResourceIdentifier *mapDefinition, CREFSTRING mapName) |
| Initializes a new MgMapBase object given a resource service, map definition, and a name for the map. This method is used for MapGuide Viewers or for offline map production. | |
| virtual MgEnvelope * | GetDataExtent () |
| virtual INT32 | GetDisplayDpi () |
| virtual INT32 | GetDisplayHeight () |
| virtual INT32 | GetDisplayWidth () |
| virtual double | GetFiniteDisplayScaleAt (INT32 index) |
| virtual INT32 | GetFiniteDisplayScaleCount () |
| virtual MgLayerGroupCollection * | GetLayerGroups () |
| Returns this map's layer groups. | |
| virtual MgLayerCollection * | GetLayers () |
| virtual MgResourceIdentifier * | GetMapDefinition () |
| Returns the resource identifier that specifies the location of the map definition that was used to create this map. | |
| virtual MgEnvelope * | GetMapExtent () |
| virtual STRING | GetMapSRS () |
| virtual STRING | GetName () |
| Gets the name of this map. | |
| virtual STRING | GetObjectId () |
| STRING | GetSessionId () |
| virtual MgPoint * | GetViewCenter () |
| Gets the current center point of the map, in the spatial reference system of the map. | |
| virtual double | GetViewScale () |
| MgMapBase () | |
| Constructs an empty un-initialized MgMapBase object. | |
| virtual void | Open (MgResourceService *resourceService, CREFSTRING mapName) |
| Loads the map object from a session repository. | |
