  • Draws a second line to the screen.

public void ResetTransform_Example(PaintEventArgs e)

    // Create a Pen object.
    Pen myPen = new Pen(Color.Black, 3);

    // Scale the transformation matrix of myPen.
    myPen.ScaleTransform(2, 1);

    // Draw a line with myPen.
    e.Graphics.DrawLine(myPen, 10, 0, 10, 200);

    // Reset the transformation matrix of myPen to identity.

    // Draw a second line with myPen.
    e.Graphics.DrawLine(myPen, 100, 0, 100, 200);
