ArcGIS.Core.Geometry Namespace / Coordinate2D Structure / Rotate Method / Rotate(Double,Coordinate2D) Method
The angle in radians defining the rotation.
The axis around which the Coordinate2D is rotated.
Example

In This Topic
    Rotate(Double,Coordinate2D) Method
    In This Topic
    Rotates the Coordinate2D around an axis defined by another Coordinate2D.
    Syntax
    public void Rotate( 
       double angle,
       Coordinate2D axis
    )
    Public Overloads Sub Rotate( _
       ByVal angle As Double, _
       ByVal axis As Coordinate2D _
    ) 

    Parameters

    angle
    The angle in radians defining the rotation.
    axis
    The axis around which the Coordinate2D is rotated.
    Exceptions
    ExceptionDescription
    angle is NaN.
    Remarks
    The Coordinate2D is rotated a given input angle measured in radians around the specified axis defined by the input Coordinate2D.
    Example
    2D Vector Operations
    Coordinate2D v = new Coordinate2D(0, 1);
    // v.Magnitude = 1
    
    Coordinate2D other = new Coordinate2D(-1, 0);
    double dotProduct = v.DotProduct(other);
    // dotProduct = 0
    
    Coordinate2D w = v + other;
    // w = (-1, 1)
    
    w += other;
    // w = (-2, 1)
    
    w -= other;
    // w = (-1, 1)
    
    w = v;
    w.Rotate(Math.PI, other);
    // w = (-2, -1)
    
    w = other;
    
    w.Scale(-4);
    // w = (4, 0)
    // w.Magnitude = 4
    
    w.Move(-1, 4);
    // w = (3, 4)
    // w.Magnitude = 5
    
    w.Move(-6, -1);
    Tuple<double, double> components = w.QueryComponents();
    // components = (-3, 3)
    // w.Magnitude = 3 * Math.Sqrt(2)
    
    Coordinate2D unitVector = w.GetUnitVector();
    // w = (-Math.Sqrt(2) / 2, Math.Sqrt(2) / 2)
    // w.Magnitude = 1
    
    
    w.SetComponents(3, 4);
