title: image not appearing on secondary tile
body: <p>Hi i'm trying to resize an image to show it in a secondary tile.My code works fine  but i don't know what i'm doing wrong because when the image is bigger than 1000*1000   the image is not shown in the secondary tile
  this is my code  that i use to resize </p>
  
  <pre><code>//restablecemos el nuevo tamañao 100*100
              using (var sourceStream = await file.OpenAsync(FileAccessMode.Read))
              {
                  BitmapDecoder decoder = await BitmapDecoder.CreateAsync(sourceStream);
                  BitmapTransform transform = new BitmapTransform() { ScaledHeight =100, ScaledWidth= 100 };
                  PixelDataProvider pixelData = await decoder.GetPixelDataAsync(
                  BitmapPixelFormat.Rgba8,
                  BitmapAlphaMode.Straight,
                  transform,
                  ExifOrientationMode.RespectExifOrientation,
                  ColorManagementMode.DoNotColorManage);
  
                  using (var destinationStream = await localfile.OpenAsync(FileAccessMode.ReadWrite))
                  {
                      BitmapEncoder encoder = await BitmapEncoder.CreateAsync(BitmapEncoder.JpegEncoderId, destinationStream);
                      encoder.SetPixelData(BitmapPixelFormat.Rgba8, BitmapAlphaMode.Premultiplied, 100,100,96, 96, pixelData.DetachPixelData());
                      await encoder.FlushAsync();
                  }
              }

  <p>and this is my code that i use to pin and show the secondary tile</p>
  
  <pre><code>  private async void btnpin(object sender, RoutedEventArgs e)
      {
  
          //mantenmos abierta el appbar
          this.miappbar.IsSticky = true;
  
          //obtenemos la imagen del .json y la mostramos en  la nota
          Uri smalllogo = new Uri(pequeniaImagen);
  
          //creamos el secondary tile
          SecondaryTile secondary = new SecondaryTile(logoSecondaryTileld, String.Format("{0} {1:d}",pageTitle.Text,Convert.ToDateTime(tvFecha.Text)),pageTitle.Text,logoSecondaryTileld, TileOptions.ShowNameOnLogo,smalllogo);
          secondary.DisplayName =pageTitle.Text;//nombre de la nota
          //obtenemos el color de fondo del secondary tile
