SetSegmentStartWidth Method (IPolyLine)
Success[out]
True if the start width is set, false if not

Sets the start width of the specified 2D PolyLine segment.

.NET Syntax

Visual Basic (Declaration) 
Function SetSegmentStartWidth( _
   long SegmentIndex As System.Integer, _
   double 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
