How to customize the bridging style for connector in WPF Diagram (SfDiagram)?

//overriding CreateSegments method of Connector 
protected override IEnumerable<PathSegment> CreateSegments(Point start, Point end, BridgeDirection direction)
{
  Matrix m = Matrix.Identity;
  MatrixTransform trans = new MatrixTransform(m);
  var pathsegment = new List<PathSegment>()
  {
    new LineSegment() {Point = trans.Transform(new Point(start.X, start.Y - 10))},
    new LineSegment() {Point = trans.Transform(new Point(start.X + 16, start.Y - 10))},
    new LineSegment() {Point = trans.Transform(new Point(start.X + 16, start.Y))},
    new LineSegment() {Point =trans.Transform(new Point(end.X+16, end.Y)) }
  };
  foreach (var line in pathsegment)
  {
                yield return line;
  }
}
