通过

Matrix.Scale(Double, Double) 方法

  • 参考

定义

命名空间:
System.Windows.Media
程序集:
WindowsBase.dll

在此 Matrix 结构后面追加指定的缩放向量。

public:
 void Scale(double scaleX, double scaleY);
public void Scale (double scaleX, double scaleY);
member this.Scale : double * double -> unit
Public Sub Scale (scaleX As Double, scaleY As Double)

参数

scaleX
Double

此 Matrix 要沿 x 轴缩放的值。

scaleY
Double

此 Matrix 要沿 y 轴缩放的值。

示例

以下示例演示如何缩放 Matrix 结构。


private Matrix scaleExample()
{
    Matrix myMatrix = new Matrix(5, 10, 15, 20, 25, 30);
    
    // Scale myMatrix by a horizontal factor of 2
    // and a vertical factor of 4 about the origin.
    // After this operation,
    // myMatrix is equal to (10, 40, 30, 80, 50, 120)
    myMatrix.Scale(2, 4);
    
    return myMatrix;
}

private Matrix scaleAboutPointExample()
{
    Matrix myMatrix = new Matrix(5, 10, 15, 20, 25, 30);
    
    // Scale myMatrix by a horizontal factor of 2
    // and a vertical factor of 4 about the 
    // point (100,100).
    // After this operation,
    // myMatrix is equal to (10, 40, 30, 80, -50, -180)
    myMatrix.ScaleAt(2, 4, 100, 100);
    
    return myMatrix;
}
