Hi, I am quite new to WriteableBitmapEx. I tried to load a png file in a WinRT Project by using a WriteableBitmap object and WriteableBitmapEx included via nuget.
The Image is
My code is
async void MainPage_Loaded(object sender, RoutedEventArgs e)
WriteableBitmap image = new WriteableBitmap(100, 100);
StorageFile file = await Package.Current.InstalledLocation.GetFileAsync("Assets\\Plan_cathedrale_Amiens.png");
IRandomAccessStreamWithContentType randomAccessStream = await file.OpenReadAsync();
private void Transform(WriteableBitmap source)
Color bottomleft = source.GetPixel(5, 5);
The line Color bottomleft = source.GetPixel(5, 5); is the one goind bad and throwing an AccessViolationException.
I would very much appreciate any help.

It's simply not loaded at the time you want to access the pixels. Just check the PixelWidth and Height properties.
You should use the WBX methods to load your stuff:
Uri imageUri = new Uri(BaseUri, "///Assets/Plan_cathedrale_Amiens.png");
image = await BitmapFactory.New(1, 1).FromContent(imageUri);
