Public Member Functions
virtual INT32	GetdatumWarningCount (void)=0
	Gets the datum warning count.
virtual MgCoordinateSystemGeodeticPath *	GetExplicitGeodeticPath ()=0
	Returns the definition of the geodetic path used to build the transformation, but only if the path was explicitly obtained from the Geodetic Path dictionary.
virtual MgCoordinateSystemGeodeticTransformDef *	GetGeodeticTransformation (INT32 index)=0
	Returns a pointer to the catalog-resident(!) geodetic transformation definition indicated by the index parameter.
virtual INT32	GetGeodeticTransformationCount ()=0
	Returns the number of geodetic transformations used in the implicit or explicit path used to convert the source to the target coordinate system. For a geodetic transformation to take place, both the source and the target coordinate systems have to be referenced to a datum.
virtual INT32	GetGeodeticTransformationDirection (INT32 index)=0
	Returns the direction of the transformation definition indicated by the index parameter.
virtual INT32	GetLastTransformStatus ()=0
	Gets the last transformation status.
virtual MgCoordinateSystem *	GetSource ()=0
	Gets the source coordinate system (MgCoordinateSystem)
virtual INT32	GetSourceWarningCount (void)=0
	Gets the source warning count.
virtual MgCoordinateSystem *	GetTarget ()=0
	Gets the target coordinate system (MgCoordinateSystem)
virtual INT32	GetTargetWarningCount (void)=0
	Gets the target warning count.
virtual MgLineString *	GridLine (MgCoordinate *fromPnt, MgCoordinate *toPnt, double curvePrecision, UINT32 maxPoints)=0
	Generates a MgLineString which represents, in the target coordinate system, the linear line segment provided in the source coordinate system.
virtual void	IgnoreDatumShiftWarning (bool bIgnoreDatumShiftWarning)=0
	Sets whether datum shift warnings will be ignored.
virtual void	IgnoreOutsideDomainWarning (bool bIgnoreOutsideDomainWarning)=0
	Sets whether outside domain warnings will be ignored.
virtual bool	IsIgnoreDatumShiftWarning ()=0
	Gets whether datum shift warnings will be ignored.
virtual bool	IsIgnoreOutsideDomainWarning ()=0
	Gets whether outside domain warnings will be ignored.
virtual bool	IsValidSourcePoint (double x, double y)=0
	Gets whether the given source point is valid.
virtual bool	IsValidSourcePoint (double x, double y, double z)=0
	Gets whether the given source point is valid.
virtual bool	IsValidTargetPoint (double x, double y)=0
	Gets whether the given target point is valid.
virtual bool	IsValidTargetPoint (double x, double y, double z)=0
	Gets whether the given target point is valid.
virtual void	ResetLastTransformStatus ()=0
	Resets the last transformation status.
virtual void	SetSourceAndTarget (MgCoordinateSystem *pSource, MgCoordinateSystem *pTarget)=0
	Sets the source and target coordinate systems.
virtual MgCoordinate *	Transform (double x, double y)=0
	Transforms the given X and Y values whose frame of reference is the source coordinate system into an XY coordinate whose frame of reference is the target coordinate system.
virtual MgCoordinate *	Transform (double x, double y, double z)=0
	Transforms the given X, Y and Z values whose frame of reference is the source coordinate system into a coordinate whose frame of reference is the target coordinate system.
virtual MgCoordinate *	Transform (MgCoordinate *coordinate)=0
	Transforms the given coordinate whose frame of reference is the source coordinate system into a coordinate whose frame of reference is the target coordinate system.
virtual MgEnvelope *	Transform (MgEnvelope *envelope)=0
	Transforms an MgEnvelope instance for the source coordinate system into an MgEnvelope instance for target coordinate system.
virtual void	TransformCoordinate (MgCoordinate *coordinate)=0
	Transforms the specified coordinate in-place.
virtual MgCoordinate *	TransformM (double x, double y, double m)=0
	Transforms the given X, Y, and M values whose frame of reference is the source coordinate system into a coordinate whose frame of reference is the target coordinate system.
virtual MgCoordinate *	TransformM (double x, double y, double z, double m)=0
	Transforms the given X, Y, Z, and M values whose frame of reference is the source coordinate system into a coordinate whose frame of reference is the target coordinate system.
