Syntax

Java

WinRT C#

C++

public class AnnDeserializeOptions

Public Class AnnDeserializeOptions

public sealed class AnnDeserializeOptions

@interface LTAnnDeserializeOptions : NSObject

public class AnnDeserializeOptions

function Leadtools.Annotations.Core.AnnDeserializeOptions()

public: 
   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.

using LeadtoolsExamples.Common; 
using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Core; 
using Leadtools.Codecs; 
 
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); 
}
