Rect.Transform 方法

定义

命名空间:

System.Windows

程序集:

WindowsBase.dll

使用指定的矩阵转换矩形。

重载

Transform(Matrix)	通过应用指定矩阵来转换矩形。
Transform(Rect, Matrix)	返回矩形，该矩形是通过向指定矩形应用指定矩阵而得到的。

Transform(Matrix)

通过应用指定矩阵来转换矩形。

public:
 void Transform(System::Windows::Media::Matrix matrix);

public void Transform (System.Windows.Media.Matrix matrix);

member this.Transform : System.Windows.Media.Matrix -> unit

Public Sub Transform (matrix As Matrix)

参数

matrix

Matrix

指定将应用转换的矩阵。

示例

以下示例演示如何使用Transform(Matrix)该方法通过使用 a Matrix转换Rect结构。

private Rect transformExample1()
{
    // Initialize new rectangle.
    Rect myRectangle = new Rect();

    // Set the Size property of the rectangle with a width of 200
    // and a height of 60.
    myRectangle.Size = new Size(200, 60);

    // Creating a Matrix structure.
    Matrix myMatrix = new Matrix(0, 1, 1, 0, 20, 2);

    // The Transform method transforms this rectangle using the specified matrix.  
    // myRectangle location changed from 0,0 to 20, 2 and the size changed from
    // 200,60 to 60,200.
    myRectangle.Transform(myMatrix);

    return myRectangle;
}

Transform(Rect, Matrix)

返回矩形，该矩形是通过向指定矩形应用指定矩阵而得到的。

public:
 static System::Windows::Rect Transform(System::Windows::Rect rect, System::Windows::Media::Matrix matrix);

public static System.Windows.Rect Transform (System.Windows.Rect rect, System.Windows.Media.Matrix matrix);

static member Transform : System.Windows.Rect * System.Windows.Media.Matrix -> System.Windows.Rect

Public Shared Function Transform (rect As Rect, matrix As Matrix) As Rect

参数

rect

Rect

作为转换基础的矩形。

matrix

Matrix

指定将应用转换的矩阵。

返回

Rect

此操作生成的矩形。

示例

以下示例演示如何使用 Transform(Rect, Matrix) 该方法创建一个新 Rect 结构，该结构由将 a Matrix 应用于现有矩形而产生。

private Rect transformExample2()
{
    // Initialize new rectangle.
    Rect myRectangle = new Rect();

    // Set the Size property of the rectangle with a width of 200
    // and a height of 60.
    myRectangle.Size = new Size(200, 60);

    // Creating a Matrix structure.
    Matrix myMatrix = new Matrix(0, 1, 1, 0, 20, 2);

    // The Transform method Transforms the specified rectangle using the specified matrix 
    // and returns the results.  
    // resultRect is an alterned version of myRectangle with a location of 20,2 rather
    // then 0,0 and a size of 60,200 rather then 200,60.
    Rect resultRect = Rect.Transform(myRectangle,myMatrix);

    return resultRect;
}
