DensifyByLength Method (IGeometryEngine)

In This Topic

Densifies the specified geometry.

Syntax

C#
Visual Basic (Declaration)

Geometry DensifyByLength( 
   Geometry geometry,
   double maxSegmentLength
)

Function DensifyByLength( _
   ByVal geometry As Geometry, _
   ByVal maxSegmentLength As Double _
) As Geometry

Parameters

geometry: The geometry to be densified.
maxSegmentLength: The maximum segment length allowed in the output geometry.

Return Value

Returns the densified geometry.

Exceptions

Exception	Description
System.NotImplementedException	The method is not implemented for GeometryBag or Multipatch.
System.ArgumentNullException	Geometry is null or empty.

Remarks

The densify operation adds vertices to the input geometry.

Example

Densify by Length

// densify a line segment
MapPoint startPt = MapPointBuilderEx.CreateMapPoint(1.0, 1.0);
MapPoint endPt = MapPointBuilderEx.CreateMapPoint(1, 21);
LineSegment line = LineBuilderEx.CreateLineSegment(startPt, endPt);
Polyline polyline = PolylineBuilderEx.CreatePolyline(line);

Geometry geom = GeometryEngine.Instance.DensifyByLength(polyline, 2);
Polyline result = geom as Polyline;


// densify a circular arc
MapPoint fromPt = MapPointBuilderEx.CreateMapPoint(2, 1);
MapPoint toPt = MapPointBuilderEx.CreateMapPoint(1, 2);
Coordinate2D interiorPt = new Coordinate2D(1 + Math.Sqrt(2) / 2, 1 + Math.Sqrt(2) / 2);

EllipticArcBuilderEx cab = new EllipticArcBuilderEx(fromPt, toPt, interiorPt);
EllipticArcSegment circularArc = cab.ToSegment();
polyline = PolylineBuilderEx.CreatePolyline(circularArc);
geom = GeometryEngine.Instance.DensifyByLength(polyline, 2);
result = geom as Polyline;

Requirements

Target Platforms: Windows 11, Windows 10, Windows 8.1
