Esempio

Nell'esempio seguente viene illustrato come ridimensionare una Matrix struttura.

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;
}
