Segment.GetBendPoints method

Gets bend points

Syntax:

Function GetBendPoints(ByRef Offset1 As Double, ByRef Offset2 As Double, Optional ByVal OffsetType As cdrSegmentOffsetType = cdrParamSegmentOffset) As Long

Parameters:

Name	Type	Description
Offset1	Double	Specifies the offset, in document units, of the first bend point
Offset2	Double	Specifies the offset, in document units, of the second bend point
OffsetType	cdrSegmentOffsetType	Specifies the type of offset of the point on the curve's subpath, and returns cdrSegmentOffsetType.

Remarks:

The GetBendPoints method returns the number of bend points in a curve segment. A bend point is the offset where a curve segment bends (that is, where it changes its curvature from positive to negative). There can be a maximum of two bend points per segment, and possibly none.

Examples:

The following VBA example marks, with small circles, all bend points in the selected curve.

Sub Test()
  Dim seg As Segment
  Dim t1 As Double, t2 As Double, n As Long
  For Each seg In ActiveShape.Curve.Segments
    n = seg.GetBendPoints(t1, t2)
    If n > 1 Then MarkPoint seg, t2
      If n > 0 Then MarkPoint seg, t1
      Next seg
    End Sub
    Private Sub MarkPoint(seg As Segment, t As Double)
      Dim x As Double, y As Double
      Dim s As Shape
      seg.GetPointPositionAt x, y, t
      Set s = ActiveLayer.CreateEllipse2(x, y, 0.03)
      s.Fill.UniformColor.RGBAssign 255, 255, 0
    End Sub
