CanvasShapes.AddCurve Method
Creates a Bézier curve. Returns a CanvasShapes object that represents the new curve.
Namespace: Microsoft.Office.Interop.PowerPoint
Assembly: Microsoft.Office.Interop.PowerPoint (in Microsoft.Office.Interop.PowerPoint.dll)
Syntax
'Declaration
Function AddCurve ( _
SafeArrayOfPoints As Object _
) As Shape
'Usage
Dim instance As CanvasShapes
Dim SafeArrayOfPoints As Object
Dim returnValue As Shape
returnValue = instance.AddCurve(SafeArrayOfPoints)
Shape AddCurve(
Object SafeArrayOfPoints
)
Parameters
- SafeArrayOfPoints
Type: System.Object
An array of coordinate pairs that specifies the vertices and control points of the curve. The first point you specify is the starting vertex, and the next two points are control points for the first Bézier segment. Then, for each additional segment of the curve, you specify a vertex and two control points. The last point you specify is the ending vertex for the curve. Note that you must always specify 3n + 1 points, where n is the number of segments in the curve.
Return Value
Type: Microsoft.Office.Interop.PowerPoint.Shape
Shape
Examples
The following example adds a two-segment Bézier curve to myDocument.
Dim pts(1 To 7, 1 To 2) As Single
pts(1, 1) = 0
pts(1, 2) = 0
pts(2, 1) = 72
pts(2, 2) = 72
pts(3, 1) = 100
pts(3, 2) = 40
pts(4, 1) = 20
pts(4, 2) = 50
pts(5, 1) = 90
pts(5, 2) = 120
pts(6, 1) = 60
pts(6, 2) = 30
pts(7, 1) = 150
pts(7, 2) = 90
Set myDocument = ActivePresentation.Slides(1)
