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

public:
 void MultiplyTransform(System::Drawing::Drawing2D::Matrix ^ matrix);
public void MultiplyTransform (System.Drawing.Drawing2D.Matrix matrix);
member this.MultiplyTransform : System.Drawing.Drawing2D.Matrix -> unit
Public Sub MultiplyTransform (matrix As Matrix)

Parameters

matrix
Matrix

The Matrix object by which to multiply the transformation matrix.

Examples

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_Example1( PaintEventArgs^ e )
   {
      
      // Create a Pen object.
      Pen^ myPen = gcnew Pen( Color::Black,5.0f );
      
      // Create a translation matrix.
      Matrix^ penMatrix = gcnew Matrix;
      penMatrix->Scale( 3, 1 );
      
      // Multiply the transformation matrix of myPen by transMatrix.
      myPen->MultiplyTransform( penMatrix );
      
      // Draw a line to the screen.
      e->Graphics->DrawLine( myPen, 0, 0, 100, 100 );
   }

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

Public Sub MultiplyTransform_Example1(ByVal e As PaintEventArgs)

    ' Create a Pen object.
    Dim myPen As New Pen(Color.Black, 5)

    ' Create a translation matrix.
    Dim penMatrix As New Matrix
    penMatrix.Scale(3, 1)

    ' Multiply the transformation matrix of myPen by transMatrix.
    myPen.MultiplyTransform(penMatrix)

    ' Draw a line to the screen.
    e.Graphics.DrawLine(myPen, 0, 0, 100, 100)
End Sub

Remarks

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

Public Sub MultiplyTransform_Example2(ByVal e As PaintEventArgs)

    ' Create a Pen object.
    Dim myPen As New Pen(Color.Black, 5)

    ' Create a translation matrix.
    Dim penMatrix As 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)
End Sub

Remarks

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