Namespace:   System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public void MultiplyTransform(
	Matrix matrix


Type: System.Drawing.Drawing2D.Matrix

The Matrix object by which to multiply the transformation matrix.

This method prepends the multiplication matrix specified in the matrix parameter to the transformation matrix for the multiplication operation.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, 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_Example1(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.

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