Add Point Annotation to Document

Introduction

GroupDocs.Annotation for .NET is a powerful tool that allows developers to add various types of annotations to documents programmatically. In this tutorial, we will focus on adding a Point Annotation to a document using C#.

Prerequisites

Before we begin, make sure you have the following:

1. Basic understanding of C# programming language.
2. Visual Studio installed on your system.
3. GroupDocs.Annotation for .NET library installed. You can download it from here.

Importing Necessary Namespaces

To get started, you need to import the required namespaces into your C# project:

using System;
using System.Collections.Generic;
using System.IO;
using GroupDocs.Annotation.Models;
using GroupDocs.Annotation.Models.AnnotationModels;
using GroupDocs.Annotation.Options;

Step 1: Define Output Path

string outputPath = Path.Combine("Your Document Directory", "result" + Path.GetExtension("input.pdf"));

In this step, we define the output path where the annotated document will be saved.

Step 2: Initialize Annotator

using (Annotator annotator = new Annotator("input.pdf"))

Here, we initialize the Annotator object with the input document (“input.pdf”).

Step 3: Create Point Annotation

PointAnnotation point = new PointAnnotation
{
    Box = new Rectangle(100, 100, 0, 0),
    CreatedOn = DateTime.Now,
    Message = "This is point annotation",
    PageNumber = 0,
    Replies = new List<Reply>
    {
        new Reply
        {
            Comment = "First comment",
            RepliedOn = DateTime.Now
        },
        new Reply
        {
            Comment = "Second comment",
            RepliedOn = DateTime.Now
        }
    }
};

In this step, we create a PointAnnotation object and specify its properties such as position, message, page number, and replies.

Step 4: Add Annotation

annotator.Add(point);

Here, we add the created point annotation to the document.

Step 5: Save Document

annotator.Save(outputPath);

Finally, we save the annotated document to the specified output path.

Conclusion

In this tutorial, we’ve learned how to add a Point Annotation to a document using GroupDocs.Annotation for .NET. With this powerful library, you can enhance your document management applications by incorporating annotation functionalities.
