Matrix.Prepend Method

Prepends the specified Matrix structure onto this Matrix structure.

Namespace: System.Windows.Media
Assembly: WindowsBase (in windowsbase.dll)

public void Prepend (
	Matrix matrix
)
public void Prepend (
	Matrix matrix
)
public function Prepend (
	matrix : Matrix
)
You cannot use methods in XAML.

Parameters

matrix

The Matrix structure to prepend to this Matrix structure.

This operation is the same as multiplying the parameter matrix by this Matrix structure. Matrix multiplication is not commutative, however, so this operation is not the same as multiplying this Matrix structure by the parameter matrix; that is, matrix * this is not the same as this * matrix.

In a composite transformation, the order of individual transformations is important. For example, if you first rotate, then scale, then translate, you get a different result than if you first translate, then rotate, then scale. One reason order is significant is that transformations like rotation and scaling are done with respect to the origin of the coordinate system. Scaling an object that is centered at the origin produces a different result than scaling an object that has been moved away from the origin. Similarly, rotating an object that is centered at the origin produces a different result than rotating an object that has been moved away from the origin.

The following example shows how to prepend a Matrix onto another Matrix.

private Matrix prependExample()
{
    

    Matrix matrix1 = new Matrix(5, 10, 15, 20, 25, 30);
    Matrix matrix2 = new Matrix(2, 4, 6, 8, 10, 12);

    matrix1.Prepend(matrix2);

    // matrix1 is equal to (70,100,150,220,255,370). 
    return matrix1;

      
}
