GeoEllipse class

The GeoEllipse class defines an geometric ellipse with horizontal radius xRadius, and vertical radius yRadius. The class may be used to calculate coordinates on the ellipse given an angle in radians or degrees.

Methods

coordinate(GeoAngle angle, [GeoCoordinate2D? center]) → GeoCoordinate2D

Get coordinate on an ellipse centered at center at an angle given in GeoAngle (either radian or degree). If center is not specified, origin (0,0) is assumed.

coordinateByDegree(double angle, [GeoCoordinate2D? center]) → GeoCoordinate2D

Get coordinate on an ellipse centered at center at an angle given in degrees. If center is not specified, origin (0,0) is assumed.

coordinateByRadian(double angle, [GeoCoordinate2D? center, double factor = 1.0]) → GeoCoordinate2D

Get coordinate on an ellipse centered at center at an angle given in radians. If center is not specified, origin (0,0) is assumed. Factor factor is multiplied with the amplitude at the angle to support polar charting

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

toString() → String

String representation of GeoEllipse showing horizontal (x) radius, and vertical (y) radius.

Operators

operator ==(Object other) → bool

The equality operator.
