Point4D.Subtract(Point4D, Point4D) 方法

定义

命名空间:

System.Windows.Media.Media3D

程序集:

PresentationCore.dll

从一个 Point4D 结构中减去一个 Point4D 结构。

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

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

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

Public Shared Function Subtract (point1 As Point4D, point2 As Point4D) As Point4D

参数

point1

Point4D

作为被减数的 Point4D 结构。

point2

Point4D

要从 point1 中减去的 Point4D 结构。

返回

Point4D

返回 point1 和 point2 之间的差。

示例

以下示例演示如何从Point4D结构中减去Point4D结构。

// Subtracts a Point3D from a Point4D using the static Subtract method. 
// Returns a Point4D.

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

pointResult = Point4D.Subtract(point1, point2);
// pointResult is equal to (-5, -35, -59, -71)

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

' Subtracts a Point3D from a Point4D using the static Subtract method. 
' 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 = Point4D.Subtract(point1, point2)
' pointResult is equal to (-5, -35, -59, -71)

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