Creates a Named Seed object by following the current open Link item to make a closed loop.
Visual Basic |
---|
Public Function TopoEdgeFill( _ ByVal seed As String, _ ByVal bForwards As Integer, _ ByVal filter As String _ ) As Integer |
True
|
Follow the current open Link item from the start node to the end node. |
False
|
Follow the current open Link item from the end node to the start node. |
True on success, False
on failure.
The Link following algorithm always turns left at a Node. Therefore this method will always return an anti-clockwise TopoPolygon. The exception to this is if the current Link item is an edge Link. In this case one value of bForwards will return a clockwise perimeter TopoPolygon, and the other will return an anti-clockwise TopoPolygon.
