DeserializeObjectError Event

Summary
Represents the event to trigger when an error occurs during loading an annotation object.
Syntax
C#
C++/CLI
Java
Python
public event EventHandler<AnnSerializeObjectEventArgs> DeserializeObjectError 
public void addDeserializeObjectErrorListener(AnnSerializeObjectListener listener) 
public void removeDeserializeObjectErrorListener(AnnSerializeObjectListener listener) 
public:  
   event EventHandler<AnnSerializeObjectEventArgs^>^ DeserializeObjectError 
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.

PropertyDescription
AnnObject The annotation object being loaded or saved.
Remarks

AnnSerializeObjectEventArgs This event will trigger once for each annotation object being loaded with the AnnSerializeObjectEventArgs event data members containing the following:

Member Description
AnnSerializeObjectEventArgs.Error

The error that occurred.

AnnSerializeObjectEventArgs.TypeName

The type name of the AnnObject being loaded.

AnnSerializeObjectEventArgs.AnnObject

The AnnObject being loaded.

AnnSerializeObjectEventArgs.SkipObject

Set to false. You can change this value to true to skip loading this object and continue to the next.

Example
C#
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); 
}
