Example
 
[TestMethod]
public async Task AnnCodecs_AnnDeserializeOptions()
{
   // Create a new annotation container, 8.5 by 11 inches
   AnnContainer container = new AnnContainer();
   // Size must be in annotation units (1/720 of an inch)
   container.Size = LeadSizeDHelper.Create(8.5 * 720, 11 * 720);
   double inch = 720.0;
   // Add a red line object, from 1in 1in to 2in 2in
   AnnPolylineObject lineObj = new AnnPolylineObject();
   lineObj.Points.Add(LeadPointDHelper.Create(1 * inch, 1 * inch));
   lineObj.Points.Add(LeadPointDHelper.Create(2 * inch, 2 * inch));
   lineObj.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create("Red"), LeadLengthDHelper.Create(1));
   container.Children.Add(lineObj);

   // Add a blue on yellow rectangle from 3in 3in to 4in 4in
   AnnRectangleObject rectObj = new AnnRectangleObject();
   rectObj.Rect = LeadRectDHelper.Create(3 * inch, 3 * inch, 1 * inch, 1 * inch);
   rectObj.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create("Blue"), LeadLengthDHelper.Create(1));
   rectObj.Fill = AnnSolidColorBrush.Create("Yellow");
   container.Children.Add(rectObj);

   // Show the container
   ShowContainer("Before save", container);

   // Create the codecs object to save and load annotations
   AnnCodecs codecs = new AnnCodecs();

   // Save the container
   string destFileName = @"container.xml";
   StorageFile saveFile = await Tools.AppLocalFolder.CreateFileAsync(destFileName);
   await codecs.SaveAsync(saveFile, container, AnnFormat.Annotations, 1);

   // delete the container
   container = null;

   // Create a new instance of AnnDeserializeOptions and Hook to the DeserializeObject and DeserializeObjectError events
   AnnDeserializeOptions deserializeOptions = new AnnDeserializeOptions();
   deserializeOptions.DeserializeObject += deserializeOptions_DeserializeObject;
   deserializeOptions.DeserializeObjectError += deserializeOptions_DeserializeObjectError;

   // Set it as our deserialize options
   codecs.DeserializeOptions = deserializeOptions;

   // Load the container we just saved
   container = await codecs.LoadAsync(saveFile, 1);

   // Show it
   ShowContainer("After load", container);
}

void deserializeOptions_DeserializeObjectError(object sender, AnnSerializeObjectEventArgs e)
{
   Debug.WriteLine(e.Error.Message);
}

void deserializeOptions_DeserializeObject(object sender, AnnSerializeObjectEventArgs e)
{
   Debug.WriteLine("loading object of type: " + e.TypeName);
}
