Esempio

L'esempio di codice seguente è progettato per l'uso con Windows Forms. È un gestore per l'evento Paint . Un Graphics oggetto viene passato all'evento e viene usato per disegnare l'immagine nel modulo. Il codice esegue le azioni seguenti:

• Crea un'immagine da un file denominato SampImag.jpg. Questo file deve trovarsi nella stessa cartella del file eseguibile dell'applicazione.

• Crea un punto in corrispondenza del quale disegnare l'angolo superiore sinistro dell'immagine.

• Disegna l'immagine non ridimensionata nel modulo.

private:
   void ImageExampleForm_Paint(System::Object^  sender, System::Windows::Forms::PaintEventArgs^  e) 
   {
      // Create image.
      Image^ newImage = Image::FromFile( "SampImag.jpg" );

      // Create Point for upper-left corner of image.
      Point ulCorner = Point(100,100);

      // Draw image to screen.
      e->Graphics->DrawImage( newImage, ulCorner );
   }

private void ImageExampleForm_Paint(object sender, PaintEventArgs e)
{         
    // Create image.
    Image newImage = Image.FromFile("SampImag.jpg");
             
    // Create Point for upper-left corner of image.
    Point ulCorner = new Point(100, 100);
             
    // Draw image to screen.
    e.Graphics.DrawImage(newImage, ulCorner);
}

Private Sub ImageExampleForm_Paint _
    (ByVal sender As System.Object, _
    ByVal e As System.Windows.Forms.PaintEventArgs) _
    Handles MyBase.Paint


    ' Create image.
    Dim newImage As Image = Image.FromFile("SampImag.jpg")

    ' Create Point for upper-left corner of image.
    Dim ulCorner As New Point(100, 100)

    ' Draw image to screen.
    e.Graphics.DrawImage(newImage, ulCorner)
End Sub

Commenti

Per disegnare un oggetto Image in un Windows Form, usare uno dei DrawImage metodi.
