Ejemplos

En el ejemplo de código siguiente se muestra cómo cargar un mapa de bits desde un identificador de Icon, mediante la enumeración GraphicsUnit y cómo usar el método Round para dibujar los límites del rectángulo de un mapa de bits.The following code example demonstrates how to load a bitmap from an Icon handle, using the GraphicsUnit enumeration, and how to use the Round method to draw the rectangle bounds of a bitmap.

Este ejemplo está diseñado para usarse con Windows Forms.This example is designed to be used with Windows Forms. Cree un formulario que contenga un botón denominado Button2.Create a form that contains a button named Button2. Pegue el código en el formulario y asocie este método al evento Click del botón.Paste the code into the form and associate this method with the button's Click event.

void Button2_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   Bitmap^ bitmap1 = Bitmap::FromHicon( SystemIcons::Hand->Handle );
   Graphics^ formGraphics = this->CreateGraphics();
   GraphicsUnit units = GraphicsUnit::Point;
   RectangleF bmpRectangleF = bitmap1->GetBounds( units );
   Rectangle bmpRectangle = Rectangle::Round( bmpRectangleF );
   formGraphics->DrawRectangle( Pens::Blue, bmpRectangle );
   delete formGraphics;
}
private void Button2_Click(System.Object sender, System.EventArgs e)
{

    Bitmap bitmap1 = Bitmap.FromHicon(SystemIcons.Hand.Handle);
    Graphics formGraphics = this.CreateGraphics();
    GraphicsUnit units = GraphicsUnit.Point;

    RectangleF bmpRectangleF = bitmap1.GetBounds(ref units);
    Rectangle bmpRectangle = Rectangle.Round(bmpRectangleF);
    formGraphics.DrawRectangle(Pens.Blue, bmpRectangle);
    formGraphics.Dispose();
}
Private Sub Button2_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button2.Click

    Dim bitmap1 As Bitmap = Bitmap.FromHicon(SystemIcons.Hand.Handle)
    Dim formGraphics As Graphics = Me.CreateGraphics()
    Dim units As GraphicsUnit = GraphicsUnit.Point
    Dim bmpRectangleF As RectangleF = bitmap1.GetBounds(units)
    Dim bmpRectangle As Rectangle = Rectangle.Round(bmpRectangleF)
    formGraphics.DrawRectangle(Pens.Blue, bmpRectangle)
    formGraphics.Dispose()
End Sub
