AnnDeserializeOptions Class

Summary

Options to use when loading annotation objects.

Syntax

Java

Objective-C

WinRT C#

public class AnnDeserializeOptions

Public Class AnnDeserializeOptions

public sealed class AnnDeserializeOptions

@interface LTAnnDeserializeOptions : NSObject

public class AnnDeserializeOptions

function Leadtools.Annotations.Core.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.
