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.
