   ref class AnnDeserializeOptions 
Remarks

This class is used as the type for AnnCodecs.DeserializeOptions and contains the following members:

Member Description
DeserializeObject

Event to trigger for each annotation object being loaded. Allows you to monitor and skip any object.

DeserializeObjectError

Event to trigger when an error occurs during loading an annotation object. Allows you to handle the error or skip it.

Example

This example will create a container, adds a line and rectangle objects to it and saves it. Then it will show how to monitor the objects being loaded.

C#
using Leadtools.Annotations.Engine; 
 
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); 
}
