EllipticArcBuilderEx Constructor(Coordinate2D,Double,Double,Double,Double,Double,SpatialReference)

Builds a new instance of the EllipticArcBuilderEx class. The new instance will be an elliptic arc.

Syntax

C#
Visual Basic (Declaration)

public EllipticArcBuilderEx( 
   Coordinate2D centerPt,
   double startAngle,
   double centralAngle,
   double rotationAngle,
   double semiMajorAxis,
   double minorMajorRatio,
   SpatialReference spatialReference
)

Public Function New( _
   ByVal centerPt As Coordinate2D, _
   ByVal startAngle As Double, _
   ByVal centralAngle As Double, _
   ByVal rotationAngle As Double, _
   ByVal semiMajorAxis As Double, _
   ByVal minorMajorRatio As Double, _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

centerPt: The center point of the elliptic arc.
startAngle: The start angle in radians measured from the rotated x-axis.
centralAngle: The central angle in radians measuring the span of the arc from startAngle to endAngle. A positive value corresponds to counterclockwise orientation.
rotationAngle: The angle in radians by which the ellipse is rotated from the x-axis. A positive value corresponds to counterclockwise rotation.
semiMajorAxis: The length of the semi-major axis.
minorMajorRatio: The ratio of the length of the semi-minor axis to the length of the semi-major axis. Must be < 1.
spatialReference: (Optional) The spatial reference of the arc. The default value is null.

Exceptions

Exception	Description
System.ArgumentException	startAngle, centralAngle, rotationAngle, semiMajorAxis or minorMajorRatio is NaN.
System.ArgumentException	centerPt is empty.
System.ArgumentException	An elliptic arc construction operation was given invalid axes. The minorMajorRatio should be < 1.

Requirements

Target Platforms: Windows 11, Windows 10, Windows 8.1
