List of all members.

Public Member Functions
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 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 STRING	GetBackgroundColor ()
	Returns the background color for the map.
virtual MgEnvelope *	GetDataExtent ()
virtual INT32	GetDisplayDpi ()
virtual INT32	GetDisplayHeight ()
virtual INT32	GetDisplayWidth ()
	Returns the current width of the map display in pixels.
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.
virtual void	SetDisplayDpi (INT32 dpi)

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.
