SetSegmentStartWidth Method (IPolyLine) Send Feedback
See Also 
Success[out]
True if the start width is set, false if not
SegmentIndex
Index of the vertex of the segment (see Remarks)
StartWidth
Start width at the specified vertex
Sets the start width of the specified 2D PolyLine segment.

Syntax

Visual Basic 
Function SetSegmentStartWidth( _
   ByVal SegmentIndex As System.Integer, _
   ByVal StartWidth As System.Double _
) As System.Boolean
C# 
System.bool SetSegmentStartWidth( 
   System.int SegmentIndex,
   System.double StartWidth
)
JavaScript 
SetSegmentStartWidth( 
   SegmentIndex : Number,
   StartWidth : Number
) : Boolean
COM native C++ 
HRESULT SetSegmentStartWidth( 
   LONG SegmentIndex,
   DOUBLE StartWidth,
   VARIANT_BOOL* Success
) 
C++ 
DSRESULT SetSegmentStartWidth( 
   long SegmentIndex,
   double StartWidth,
   bool* Success
) 

Parameters

SegmentIndex
Index of the vertex of the segment (see Remarks)
StartWidth
Start width at the specified vertex
Success[out] or Return Value
True if the start width is set, false if not

Remarks

SegmentIndex starts at 0. To determine a valid value for SegmentIndex, call IPolyLine::GetVerticesCount to get the number of vertices in the 2D PolyLine.

For this type of 2D PolyLine... Number of vertices equals...
Closed IPolyLine::GetVerticesCount
Open IPolyLine::GetVerticesCount - 1

 

Same width for its entire length
To set 2D PolyLine's... Use...
Start width only IPolyLine::SetSegmentStartWidth
End width only Same width for its entire length
Same width for its entire length IPolyLine::GlobalWidth instead of using IPolyLine::SetSegmentStartWidth and IPolyLine::SetSegmentEndWidth
