SimplifyShapeByTangentSegments(Multipart,Double,Double,IEnumerable<MapPoint>) Method

In This Topic

Removes vertices from the input polygon or polyline geometry if the segments on either side are collinear. The maxOffset parameter defines the maximum distance that the final path can be from the original path. Vertices coincident with Anchor points will not be removed. If the input geometry is a polyline, the output will be a simplified polyline. If the input geometry is a polygon, the output will be a simplified polygon.

Public Overloads Function SimplifyShapeByTangentSegments( _
   ByVal inputGeometry As Multipart, _
   ByVal maxOffset As Double, _
   Optional ByVal offsetRatio As Double, _
   Optional ByVal anchorPoints As IEnumerable(Of MapPoint) _
) As Multipart

public Multipart SimplifyShapeByTangentSegments( 
   Multipart inputGeometry,
   double maxOffset,
   double offsetRatio,
   IEnumerable<MapPoint> anchorPoints
)

Parameters

inputGeometry: The input polygon or polyline to be simplified.
maxOffset: The maximum distance that the final path can be from the original path, in the units of the input geometry's spatial reference.
offsetRatio: The ratio of segment length to offset distance, above which adjacent segments are considered collinear. This parameter is optional, default value = 250.0
anchorPoints: The collection of point locations for vertices which will not be removed. If this collection is empty, all vertices will be considered to be candidates for removal. This parameter is optional.

Return Value

A simplified geometry of the same type as the input geometry.

Exceptions

Exception	Description
System.ArgumentNullException	Input geometry cannot be null.
System.ArgumentNullException	Input geometry must have a valid spatial reference.
System.ArgumentOutOfRangeException	Max offset must be a valid number greater than zero.
ArcGIS.Core.Geometry.Exceptions.GeometryException	An error occurred while simplifying the input geometry.

Requirements

Target Platforms: Windows 11 Home, Pro, Enterprise (64 bit)

ArcGIS Pro version: 3.7 or higher.
