Matrix.Scale(Double, Double) Metoda

Definice

Připojí zadaný vektor měřítka k této Matrix struktuře.

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)

Parametry

scaleX
Double

Hodnota, o kterou se má Matrix škálovat podél osy x.

scaleY
Double

Hodnota, podle které se má Matrix škálovat podél osy y.

Příklady

Následující příklad ukazuje, jak škálovat Matrix strukturu.


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;
}
