TryCreateFromThreePointsAngleAndRatio Method (NEllipse)

In This Topic

Tries 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.

Syntax

Visual Basic
C#

'Declaration
 
Public Shared Function TryCreateFromThreePointsAngleAndRatio( _
   ByVal pt1 As NPoint, _
   ByVal pt2 As NPoint, _
   ByVal pt3 As NPoint, _
   ByVal angle As System.Double, _
   ByVal ratio As System.Double, _
   ByRef ellipse As NEllipse _
) As System.Boolean

'Usage
 
Dim pt1 As NPoint
Dim pt2 As NPoint
Dim pt3 As NPoint
Dim angle As System.Double
Dim ratio As System.Double
Dim ellipse As NEllipse
Dim value As System.Boolean
 
value = NEllipse.TryCreateFromThreePointsAngleAndRatio(pt1, pt2, pt3, angle, ratio, ellipse)

public static System.bool TryCreateFromThreePointsAngleAndRatio( 
   NPoint pt1,
   NPoint pt2,
   NPoint pt3,
   System.double angle,
   System.double ratio,
   out NEllipse ellipse
)

Parameters

pt1
pt2
pt3
angle: angle (in radians)
ratio: ratio between the major and minor ellipse axes, must be >= 1
ellipse: resulting ellipse, valid only if method returns true

Return Value

true if succeeded, otherwise false
