def DeserializeObjectError(sender,e): # sender: AnnDeserializeOptions e: AnnSerializeObjectEventArgs 

Event Data

The event handler receives an argument of type AnnSerializeObjectEventArgs containing data related to this event. The following AnnSerializeObjectEventArgs properties provide information specific to this event.

Example

using Leadtools.Annotations.Automation; using Leadtools.Annotations.Engine; using Leadtools.Annotations.Rendering; public void 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 = LeadSizeD.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(LeadPointD.Create(1 * inch, 1 * inch)); lineObj.Points.Add(LeadPointD.Create(2 * inch, 2 * inch)); lineObj.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create("Red"), LeadLengthD.Create(1)); container.Children.Add(lineObj); // Add a blue on yellow rectangle from 3in 3in to 4in 4in AnnRectangleObject rectObj = new AnnRectangleObject(); rectObj.Rect = LeadRectD.Create(3 * inch, 3 * inch, 1 * inch, 1 * inch); rectObj.Stroke = AnnStroke.Create(AnnSolidColorBrush.Create("Blue"), LeadLengthD.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"; codecs.Save(destFileName, 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 = codecs.Load(destFileName, 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); }
