Public Function TraceGeom( _ ByVal nGeom As Long, _ ByVal arclenStart As Double, _ ByVal arclenEnd As Double, _ ByVal offset As Double, _ ByVal bAllowSelfIntersections As Integer _ ) As Integer |
Parameters
- nGeom
- The index of the geometry component, starting at 0. Use GetNumGeom to get the number of geometry components in an Item.
- arclenStart
- The length along the geometry component from which to start the trace.
- arclenEnd
- The length along the geometry component at which to end the trace.
- offset
- The offset from the geometry component at which to create the LineString item.
- bAllowSelfIntersections
-
True
Allow the traced, offset LineString item to contain self-intersections. False
Remove any self-intersections from the traced, offset LineString item.
