public void MultiplyTransform (System.Drawing.Drawing2D.Matrix matrix, System.Drawing.Drawing2D.MatrixOrder order);
member this.MultiplyTransform : System.Drawing.Drawing2D.Matrix * System.Drawing.Drawing2D.MatrixOrder -> unit
Public Sub MultiplyTransform (matrix As Matrix, order As MatrixOrder)
Parameters
- order
- MatrixOrder
Member of the MatrixOrder enumeration that determines the order of the multiplication.
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
transformMatrix
matrix (a two by two identity matrix plus a zero-translation vector).Translates the transform matrix by a vector (200, 100).
Rotates the world transformation matrix of the Windows Form by 30 degrees, prepending the rotation matrix for 30 degrees to the form's transformation matrix.
Multiplies the rotated world transformation matrix by the translated
transformMatrix
, appending thetransformMatrix
to the world transformation matrix.Draws a rotated, translated ellipse.
public:
void MultiplyTransformMatrixOrder( PaintEventArgs^ e )
{
// Create transform matrix.
Matrix^ transformMatrix = gcnew Matrix;
// Translate matrix, prepending translation vector.
transformMatrix->Translate( 200.0F, 100.0F );
// Rotate transformation matrix of graphics object,
// prepending rotation matrix.
e->Graphics->RotateTransform( 30.0F );
// Multiply (append to) transformation matrix of
// graphics object to translate graphics transformation.
e->Graphics->MultiplyTransform( transformMatrix, MatrixOrder::Append );
// Draw rotated, translated ellipse.
e->Graphics->DrawEllipse( gcnew Pen( Color::Blue,3.0f ), -80, -40, 160, 80 );
}
private void MultiplyTransformMatrixOrder(PaintEventArgs e)
{
// Create transform matrix.
Matrix transformMatrix = new Matrix();
// Translate matrix, prepending translation vector.
transformMatrix.Translate(200.0F, 100.0F);
// Rotate transformation matrix of graphics object,
// prepending rotation matrix.
e.Graphics.RotateTransform(30.0F);
// Multiply (append to) transformation matrix of
// graphics object to translate graphics transformation.
e.Graphics.MultiplyTransform(transformMatrix, MatrixOrder.Append);
// Draw rotated, translated ellipse.
e.Graphics.DrawEllipse(new Pen(Color.Blue, 3), -80, -40, 160, 80);
}
Private Sub MultiplyTransformMatrixOrder(ByVal e As PaintEventArgs)
' Create transform matrix.
Dim transformMatrix As New Matrix
' Translate matrix, prepending translation vector.
transformMatrix.Translate(200.0F, 100.0F)
' Rotate transformation matrix of graphics object,
' prepending rotation matrix.
e.Graphics.RotateTransform(30.0F)
' Multiply (append to) transformation matrix of
' graphics object to translate graphics transformation.
e.Graphics.MultiplyTransform(transformMatrix, MatrixOrder.Append)
' Draw rotated, translated ellipse.
e.Graphics.DrawEllipse(New Pen(Color.Blue, 3), -80, -40, 160, 80)
End Sub
Remarks
A value of Prepend for the order
parameter specifies that the order of the multiplication is matrix
x world transformation. A value of Append for order
specifies that the order of the multiplication is world transformation x matrix
.
