Add Text Redaction Annotation to Document

Introduction

Adding a text redaction annotation to a document can be a crucial step in securely managing sensitive information. GroupDocs.Annotation for .NET provides a robust solution to achieve this seamlessly. In this tutorial, we’ll guide you through the process of adding a text redaction annotation to your document step by step.

Prerequisites

Before we begin, make sure you have the following prerequisites in place:

1. GroupDocs.Annotation for .NET: Ensure you have installed the GroupDocs.Annotation for .NET library. You can download it from the website.
2. Development Environment: Set up a development environment with a .NET compatible IDE such as Visual Studio.

Importing Namespaces

Firstly, let’s import the necessary namespaces to our 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

Define the output path where you want to save the annotated document. Ensure it’s accessible and writable.

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

Step 2: Initialize Annotator

Initialize the annotator with the input document path. Replace "input.pdf" with the path to your document.

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

Step 3: Create Text Redaction Annotation

Create a TextRedactionAnnotation object with the required properties such as PageNumber, FontColor, and Points. Customize the annotation as per your requirements.

TextRedactionAnnotation textRedaction = new TextRedactionAnnotation
{
    CreatedOn = DateTime.Now,
    Message = "This is text redaction annotation",
    PageNumber = 0,
    FontColor = 16761035,
    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
        }
    }
};

Step 4: Add Annotation and Save

Add the created annotation to the document using the annotator and save the annotated document to the specified output path.

annotator.Add(textRedaction);
annotator.Save(outputPath);

Step 5: Check Output

Finally, confirm that the document has been saved successfully to the specified output path.

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

Conclusion

In this tutorial, we’ve walked through the process of adding a text redaction annotation to a document using GroupDocs.Annotation for .NET. With these steps, you can now securely manage sensitive information within your documents.
