    Public Properties
     NameDescription
    Public PropertyAreaGets the ellipse area (PI * a * b)  
    Public PropertyBoundsGets the minimal enclosing rectangle of this ellipse.  
    Public PropertyBoundsRangeGets the range of this ellipse bounds.  
    Public PropertyCenterGets or sets the ellipse center point  
    Public PropertyEccentricityGets the eccentricity of the ellipse (the position of the focus as a fraction of the semimajor axis - computed as c / a)  
    Public PropertyFocus1Gets the first focus of the ellipse  
    Public PropertyFocus2Gets the second focus of the ellipse  
    Public PropertyFocusDistanceGets the distance of the focuses from the ellipse center (also known as c parameter)  
    Public PropertyInscribedCircleGets the circle, which can be insribed in the ellipse  
    Public PropertyInscribedCircleTransformObtains a transformation, which transforms the ellipse curve to the curve of the inscribed circle  
    Public PropertyIsEmptyDetermines whether the ellipse is with zero a or b  
    Public PropertyIsNormalizedDetermines whether the ellipse is normalized (a >= b)

    Public Methods
     NameDescription
    Public MethodAddToPathAppends the primitive to the specified graphics path.  
    Public MethodContainsOverloaded. Determines whether the rectangle contains the specified point  
    Public MethodContainsOnOutlineDetermines whether the outline of the ellipse contains the specified point.  
    Public MethodEquals  
    Public MethodGetHashCode  
    Public MethodGetOutlineLengthGets the ellipse perimeter.  
    Public MethodIntersectWithIntersects this circle with the specified line segment  
    Public MethodNormalizeNormalizes the ellipse, so that A is larger than B.  
    Public MethodPointFromAngleGets the point on the ellipse rim, which corresponds to the specified angle (in radians)  
    Public MethodPointFromTimeGets a point on the curve from a time parameter. When t is equal to 0, returns the StartPoint of the curve. When t is equal to 1, returns the EndPoint of the curve.  
    Public MethodTimeFromAngleGets the parametric angle that corresponds to the geometric one  
    Public MethodTranslateTranslates the primitive with the specified amounts.  
    Public Methodstatic (Shared in Visual Basic)TryCreateFromCenterAndTwoPointsTries to create an ellipse from a center and two points that lay on the ellipse  
    Public Methodstatic (Shared in Visual Basic)TryCreateFromThreePointsAngleAndRatioTries to create a normalized ellipse from three points, angle between the ellipse major axis and the X-axis and ratio between the major and minor axes. Returns false if the points are colinear, or any pair of points are coincident or ratio is zero.
