MgLinearRing Class Reference
[MgLinearRing]
Inherits MgRing.
Detailed Description
An MgLinearRing is a geometry component.
- Remarks:
- It is used in the construction of MgPolygon geometries. It is a closed shape where the curves connecting the coordinates are interpolated linearly. An instance of this class is constructed by calling a non-static MgGeometryFaactory::CreateLinearRing() method and, once constructed, is immutable. See the MgPolygon Class for example code showing the construction of an MgLinearRing instance.
