Summary

Represents the load and save options event data for annotation codecs.

Syntax

Objective-C

C++/CLI

Java

Python

public class AnnSerializeObjectEventArgs : EventArgs

@interface LTAnnSerializeObjectEventArgs : NSObject

public class AnnSerializeObjectEvent extends LeadEvent

public: 
   ref class AnnSerializeObjectEventArgs : EventArgs

class AnnSerializeObjectEventArgs(EventArgs):

Remarks

AnnSerializeObjectEventArgs is the data type for the following events:

AnnSerializeOptions.SerializeObject: Used during saving of an annotation file. Allows you to monitor the annotation objects being saved.
AnnDeserializeOptions.DeserializeObject: Used during loading of an annotation file. Allows you to monitor the annotation objects being loaded.
AnnDeserializeOptions.DeserializeObjectError: Used during loading of an annotation file when error occurs.

Example

using Leadtools.Annotations.Automation; 
using Leadtools.Annotations.Engine; 
using Leadtools.Annotations.Rendering; 
 
public void AnnCodecs_AnnSerializeOptions() 
{ 
   // 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(); 
 
   // Create a new instance of AnnSrializeOptions and Hook to the SerializeObject event 
   AnnSerializeOptions serializeOptions = new AnnSerializeOptions(); 
   serializeOptions.SerializeObject += serializeOptions_SerializeObject; 
 
   // Set it as our deserialize options 
   codecs.SerializeOptions = serializeOptions; 
 
   // Save the container 
   string destFileName = @"container.xml"; 
   codecs.Save(destFileName, container, AnnFormat.Annotations, 1); 
 
   // delete the container 
   container = null; 
 
   // Load the container we just saved 
   container = codecs.Load(destFileName, 1); 
 
   // Show it 
   ShowContainer("After load", container); 
} 
 
void serializeOptions_SerializeObject(object sender, AnnSerializeObjectEventArgs e) 
{ 
   AnnObject annObj = e.AnnObject; 
   if (annObj.Id == AnnObject.PolylineObjectId) 
   { 
      Debug.WriteLine("skipping a polyline during save"); 
      e.SkipObject = true; 
   } 
}
