GraphicsPath.Transform(Matrix) Metode

Definisi

Ruang nama:

System.Drawing.Drawing2D

Rakitan:

System.Drawing.Common.dll

Menerapkan matriks transformasi ke GraphicsPathini.

public:
 void Transform(System::Drawing::Drawing2D::Matrix ^ matrix);

public void Transform (System.Drawing.Drawing2D.Matrix matrix);

member this.Transform : System.Drawing.Drawing2D.Matrix -> unit

Public Sub Transform (matrix As Matrix)

Parameter

matrix

Matrix

Matrix yang mewakili transformasi yang akan diterapkan.

Contoh

Contoh kode berikut dirancang untuk digunakan dengan Windows Forms, dan memerlukan PaintEventArgse, objek peristiwa OnPaint. Kode melakukan tindakan berikut:

• Membuat jalur dan menambahkan elips ke jalur.

• Menggambar jalur ke layar.

• Membuat matriks transformasi untuk menerjemahkan jalur 100 unit ke arah sumbu x.

• Menggambar jalur yang diubah ke layar.

Perhatikan bahwa elips asli digambar dengan warna hitam dan elips yang diubah digambar dengan warna merah.

private:
   void TransformExample( PaintEventArgs^ e )
   {
      // Create a path and add and ellipse.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->AddEllipse( 0, 0, 100, 200 );

      // Draw the starting position to screen.
      e->Graphics->DrawPath( Pens::Black, myPath );

      // Move the ellipse 100 points to the right.
      Matrix^ translateMatrix = gcnew Matrix;
      translateMatrix->Translate( 100, 0 );
      myPath->Transform(translateMatrix);

      // Draw the transformed ellipse to the screen.
      e->Graphics->DrawPath( gcnew Pen( Color::Red,2.0f ), myPath );
   }

private void TransformExample(PaintEventArgs e)
{
             
    // Create a path and add and ellipse.
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddEllipse(0, 0, 100, 200);
             
    // Draw the starting position to screen.
    e.Graphics.DrawPath(Pens.Black, myPath);
             
    // Move the ellipse 100 points to the right.
    Matrix translateMatrix = new Matrix();
    translateMatrix.Translate(100, 0);
    myPath.Transform(translateMatrix);
             
    // Draw the transformed ellipse to the screen.
    e.Graphics.DrawPath(new Pen(Color.Red, 2), myPath);
}

Public Sub TransformExample(ByVal e As PaintEventArgs)

    ' Create a path and add and ellipse.
    Dim myPath As New GraphicsPath
    myPath.AddEllipse(0, 0, 100, 200)

    ' Draw the starting position to screen.
    e.Graphics.DrawPath(Pens.Black, myPath)

    ' Move the ellipse 100 points to the right.
    Dim translateMatrix As New Matrix
    translateMatrix.Translate(100, 0)
    myPath.Transform(translateMatrix)

    ' Draw the transformed ellipse to the screen.
    e.Graphics.DrawPath(New Pen(Color.Red, 2), myPath)
End Sub

Keterangan

Transformasi dapat menskalakan, menerjemahkan, memutar, atau condong GraphicsPath.
