Point4D.Subtraction(Point4D, Point4D) Operator

Definition

Namespace:

System.Windows.Media.Media3D

Assembly:

PresentationCore.dll

Subtracts a Point4D structure from a Point4D structure and returns the result as a Point4D structure.

public:
 static System::Windows::Media::Media3D::Point4D operator -(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);

public static System.Windows.Media.Media3D.Point4D operator - (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);

static member ( - ) : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> System.Windows.Media.Media3D.Point4D

Public Shared Operator - (point1 As Point4D, point2 As Point4D) As Point4D

Parameters

point1

Point4D

The Point4D structure to be subtracted from.

point2

Point4D

The Point4D structure to subtract from point1.

Returns

Point4D

Returns the difference between point1 and point2.

Examples

The following example shows how to use the overloaded subtraction operator to subtract a Point4D structure from a Point4D structure.

// Subtracts a Point4D from a Point4D using the overloaded - operator.
// Returns a Point4D.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Point4D pointResult = new Point4D();

pointResult = point1 - point2;
// pointResult is equal to (-5, -35, -59, -71) 

// Displaying Results
syntaxString = "pointResult = point1 - point2;";
resultType = "Point4D";
operationString = "Subtracting a Vector3D from a Point4D";
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString);

' Subtracts a Point4D from a Point4D using the overloaded - operator.
' Returns a Point4D.

Dim point1 As New Point4D(10, 5, 1, 4)
Dim point2 As New Point4D(15, 40, 60, 75)
Dim pointResult As New Point4D()

pointResult = point1 - point2
' pointResult is equal to (-5, -35, -59, -71) 

' Displaying Results
syntaxString = "pointResult = point1 - point2"
resultType = "Point4D"
operationString = "Subtracting a Vector3D from a Point4D"
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString)
