Pen.MultiplyTransform Method (Matrix, MatrixOrder)

Multiplies the transformation matrix for this Pen by the specified Matrix in the specified order.

Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)
public void MultiplyTransform(
	Matrix matrix,
	MatrixOrder order
)

Parameters

matrix
Type: System.Drawing.Drawing2D.Matrix

The Matrix by which to multiply the transformation matrix.

order
Type: System.Drawing.Drawing2D.MatrixOrder

The order in which to perform the multiplication operation.

This method uses the MatrixOrder enumeration element (either prepend or append) specified by the order parameter to carry out the multiplication operation.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a Pen.

  • Draws a line to the screen.

  • Multiplies the transformation matrix of the pen by the specified matrix.

  • Draws a line with the transformed pen.

public void MultiplyTransform_Example2(PaintEventArgs e)
{

    // Create a Pen object.
    Pen myPen = new Pen(Color.Black, 5);

    // Create a translation matrix.
    Matrix penMatrix = new Matrix();
    penMatrix.Scale(3, 1);

    // Multiply the transformation matrix of myPen by transMatrix.
    myPen.MultiplyTransform(penMatrix, MatrixOrder.Prepend);

    // Draw a line to the screen.
    e.Graphics.DrawLine(myPen, 0, 0, 100, 100);
}
