SideBuffer(Polyline,Double,LeftOrRightSide,LineCapType) Method

Constructs a buffer on one side of a polyline

Syntax

C#
Visual Basic (Declaration)

Geometry SideBuffer( 
   Polyline polyline,
   double distance,
   LeftOrRightSide side,
   LineCapType caps
)

Overloads Function SideBuffer( _
   ByVal polyline As Polyline, _
   ByVal distance As Double, _
   ByVal side As LeftOrRightSide, _
   ByVal caps As LineCapType _
) As Geometry

Parameters

polyline: The polyline to buffer
distance: The buffer distance
side: The side of the polyline to create the buffer
caps: The line caps

Return Value

Geometry representing the side buffer

Exceptions

Exception	Description
System.ArgumentNullException	Geometry is null or empty
System.ArgumentException	The buffer distance must be a valid floating point number.
System.ArgumentException	The method is not implemented for LineCapType.Square.

Example

// right side, round caps
SpatialReference sr = SpatialReferenceBuilder.CreateSpatialReference(102010);
List<Coordinate2D> coords = new List<Coordinate2D>()
{
  new Coordinate2D(1200, 5800),
  new Coordinate2D(1400, 5800),
  new Coordinate2D(1400, 6000),
  new Coordinate2D(1300, 6000),
  new Coordinate2D(1300, 5700)
};

Polyline polyline = PolylineBuilder.CreatePolyline(coords, sr);
Polygon output = GeometryEngine.Instance.SideBuffer(polyline, 20, LeftOrRightSide.RightSide, LineCapType.Round) as Polygon;

Requirements

Target Platforms: Windows 10, Windows 8.1, Windows 7
