Replace sticky note icon

Hi,

I am looking to change the default icon I get when adding sticky notes
via code to the PDF. Currently I am using this function:

private async void SetBitmapSource(WriteableBitmap imageBitmap)
        {
            Windows.Storage.StorageFile file = await
Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(new
Uri("ms-appx:///MyProject/MyStickyNote.png"));
            using (Windows.Storage.Streams.IRandomAccessStream
fileStream = await
file.OpenAsync(Windows.Storage.FileAccessMode.Read))
            {
                try
                {
                    await imageBitmap.SetSourceAsync(fileStream);
                }
                catch (TaskCanceledException)
                {
                    // The async action to set the WriteableBitmap's
source may be canceled if the source is changed again while the action
is in progress
                }
            }
        }

But it does not work. Is there any chance?

Thanks,
