Public Function CreateBoundary() As Integer |
Remarks
The boundary of an Item is always 1 dimension less than the Item itself.
For example:
- The boundary of a Polygon item (which is 2-dimensional) is a LineString item.
- The boundary of a LineString item (which is 1-dimensional) is two Point Items (the start and end point of the LineString).
- The boundary of a Point item (which is 0-dimensional) is nothing.
If a Group is open, then graphics are added to the Group, otherwise a new Item is created.
