Exemplos

O exemplo de código a seguir foi projetado para uso com o Windows Forms. É um manipulador para o Paint evento. Um Graphics objeto é passado para o evento e é usado para desenhar a imagem no formulário. O código executa as seguintes ações:

• Cria uma imagem de um arquivo chamado SampImag.jpg. Esse arquivo deve estar localizado na mesma pasta que o arquivo executável do aplicativo.

• Cria um ponto no qual desenhar o canto superior esquerdo da imagem.

• Desenha a imagem não dimensionada no formulário.

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

Comentários

Para desenhar um Image em um Formulário do DrawImage Windows, use um dos métodos.
