Function Previous() As Node
Member of Node
The Previous method returns the preceding node in a curve, relative to the given node.
The following VBA example creates a curve with six segments, finds the first symmetrical node, and displays the index number of the node preceding the first symmetrical node.
Sub Test() |
Dim s As Shape |
Dim n As Node |
Dim sp As SubPath |
Dim crv As Curve |
Set crv = CreateCurve(ActiveDocument) |
ActiveDocument.ReferencePoint = cdrBottomLeft |
Set sp = crv.CreateSubPath(1, 1) |
sp.AppendLineSegment 1, 1 |
sp.AppendCurveSegment 3, 3 |
sp.AppendCurveSegment 5, 1 |
sp.AppendCurveSegment 6, 4 |
sp.AppendCurveSegment 8, 2 |
sp.AppendLineSegment 10, 5 |
sp.Nodes(2).Type = cdrSmoothNode |
sp.Nodes(3).Type = cdrSmoothNode |
sp.Nodes(4).Type = cdrSymmetricalNode |
sp.Nodes(5).Type = cdrSmoothNode |
Set s = ActiveLayer.CreateCurve(crv) |
For Each n In s.Curve.Nodes |
If n.Type = cdrSymmetricalNode Then |
Set n = s.Curve.Nodes.Item(n.Index).Previous |
Exit For |
End If |
Next n |
MsgBox n.Index |
End Sub |
