Add Text Replacement Annotation to Document

Introduction

In this tutorial, we will guide you through the process of adding a Text Replacement Annotation to your documents using GroupDocs.Annotation for .NET. This powerful library allows developers to manipulate and annotate various types of documents programmatically. By the end of this tutorial, you’ll be equipped with the knowledge to seamlessly integrate text replacement annotations into your .NET applications.

Prerequisites

Before we begin, ensure that you have the following prerequisites installed:

1. .NET Framework Installed

Make sure you have the .NET Framework installed on your development machine. You can download it from the Microsoft website.

2. GroupDocs.Annotation for .NET Library

Download and install the GroupDocs.Annotation for .NET library from the website. This library provides the necessary tools and functionalities to work with annotations in various document formats.

3. Development Environment Setup

Set up your preferred development environment, such as Visual Studio, to create and run .NET applications.

Import Namespaces

Before diving into the coding part, let’s import the necessary namespaces required for working with GroupDocs.Annotation for .NET:

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

Step 1: Define Output Path

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

Here, we define the output path where the annotated document will be saved.

Step 2: Initialize Annotator

using (Annotator annotator = new Annotator("input.pdf"))
{
    // Annotation code will be placed here
}

We initialize the Annotator object by specifying the input document (“input.pdf”) within a using block to ensure proper disposal of resources.

Step 3: Create Replacement Annotation

ReplacementAnnotation replacement = new ReplacementAnnotation
{
    CreatedOn = DateTime.Now,
    FontColor = Color.Blue.ToArgb(),
    Message = "This is replacement annotation",
    Opacity = 0.7,
    PageNumber = 0,
    BackgroundColor = Color.Red.ToArgb(),
    Points = new List<Point>
    {
        new Point(80, 730), new Point(240, 730), new Point(80, 650), new Point(240, 650)
    },
    Replies = new List<Reply>
    {
        new Reply
        {
            Comment = "First comment",
            RepliedOn = DateTime.Now
        },
        new Reply
        {
            Comment = "Second comment",
            RepliedOn = DateTime.Now
        }
    },
    TextToReplace = "replaced text"
};

Here, we create a ReplacementAnnotation object with various properties such as creation date, font color, message, opacity, page number, background color, points (coordinates), replies (comments), and the text to replace.

Step 4: Add Annotation

annotator.Add(replacement);

We add the created replacement annotation to the annotator.

Step 5: Save Document

annotator.Save(outputPath);

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

Step 6: Display Success Message

Console.WriteLine($"\nDocument saved successfully.\nCheck output in {outputPath}.");

A success message is displayed indicating that the document has been saved successfully.

Conclusion

In this tutorial, we’ve covered the process of adding text replacement annotations to documents using GroupDocs.Annotation for .NET. By following the step-by-step guide and understanding the prerequisites, you can easily integrate this functionality into your .NET applications.
