virtual MgCoordinateSystemGridBoundary* MgCoordinateSystemFactory::GridBoundary	(	MgCoordinate *	southwest,
		MgCoordinate *	northeast
	)		[virtual]

Constructs a grid boundary object.

Parameters:

southwest	The coordinates of the the southwest corner of a rectangular region which represents the grid region. This point MUST indeed be southwest of the coordinate provided by the northeast parameter.
northeast	The coordinates of the the northeast corner of a rectangular region which represents the grid region. This point MUST indeed be northeast of the coordinate provided by the southwest parameter.

Returns:

Returns the grid boundary in the form used by the grid/graticule sub-system.

Exceptions:

MgOutOfMemoryException

Thrown in the event of heap memory allocation failure.

Remarks:

Externally, grid bundary objects are in viewport coordinates and define the extents of the region within which a grid is to be drawn. Such objects are often simple rectangles, but his is not a requirement.
