CreateEllipticArcSegment(MapPoint,MapPoint,Double,Double,Double,MinorOrMajor,esriArcOrientation,SpatialReference) Method

Convenience method to create a new instance of the EllipticArcSegment class. The new instance will be an elliptic arc.

Syntax

C#
Visual Basic (Declaration)

public static EllipticArcSegment CreateEllipticArcSegment( 
   MapPoint startPt,
   MapPoint endPt,
   double semiMajorAxis,
   double minorMajorRatio,
   double rotationAngle,
   MinorOrMajor minorOrMajor,
   esriArcOrientation orientation,
   SpatialReference spatialReference
)

Public Overloads Shared Function CreateEllipticArcSegment( _
   ByVal startPt As MapPoint, _
   ByVal endPt As MapPoint, _
   ByVal semiMajorAxis As Double, _
   ByVal minorMajorRatio As Double, _
   ByVal rotationAngle As Double, _
   ByVal minorOrMajor As MinorOrMajor, _
   ByVal orientation As esriArcOrientation, _
   Optional ByVal spatialReference As SpatialReference _
) As EllipticArcSegment

Parameters

startPt: The start point of the elliptic arc.
endPt: The end point of the elliptic arc.
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.
rotationAngle: The angle in radians by which the ellipse is rotated from the x-axis. A positive value corresponds to counterclockwise rotation.
minorOrMajor: The enumeration value indicating whether the arc is a minor or major arc. A minor arc is an arc such that the central angle is less than PI radians.
orientation: The value indicating if the arc is oriented clockwise or counterclockwise.
spatialReference: (Optional) The spatial reference. The default value is null.

Exceptions

Exception	Description
System.ArgumentException	semiMajorAxis, minorMajorRatio or rotationAngle is NaN.
System.ArgumentNullException	startPt or endPt is null.
InvalidParameterException	An elliptic arc construction operation was given invalid axes. The minorMajorRatio should be < 1.

Requirements

Target Platforms: Windows 11, Windows 10, Windows 8.1
