CreateEllipticArcSegment(Coordinate2D,Double,Double,Double,Double,Double,SpatialReference) Method

ArcGIS.Core.Geometry Namespace > EllipticArcBuilderEx Class > CreateEllipticArcSegment Method : CreateEllipticArcSegment(Coordinate2D,Double,Double,Double,Double,Double,SpatialReference) Method
The center point of the ellipse.
The start angle in radians measured from the rotated x-axis.
The central angle in radians measuring the span of the arc from startAngle to endAngle. A positive value corresponds to counterclockwise orientation.
The angle in radians by which the ellipse is rotated from the x-axis. A positive value corresponds to counterclockwise rotation.
The length of the semi-major axis.
The ratio of the length of the semi-minor axis to the length of the semi-major axis.
(Optional) The spatial reference of the arc. The default value is null.
Convenience method to create a new instance of the EllipticArcSegment class.
