Add Distance Annotation to Document

Introduction

In this tutorial, you will learn how to add a distance annotation to a document using GroupDocs.Annotation for .NET. Follow these steps to accomplish the task:

Prerequisites

Ensure that you have the following prerequisites in place before proceeding:

• GroupDocs.Annotation for .NET Library: Download and install the GroupDocs.Annotation for .NET library from this link.
• Document to Annotate: Prepare the document (e.g., PDF) to which you want to add the distance annotation.
• Development Environment: Set up your development environment with Visual Studio or any other IDE of your choice.

Import Namespaces

Before you begin, make sure to include the necessary namespaces in your code. These namespaces are essential for accessing the required classes and methods.

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

Step 1: Initialize Annotator

Begin by initializing the Annotator object with the path to the document you want to annotate.

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

Step 2: Create Distance Annotation

Now, create a DistanceAnnotation object and configure its properties such as box dimensions, message, opacity, pen color, etc.

DistanceAnnotation distance = new DistanceAnnotation
{
    Box = new Rectangle(200, 150, 200, 30),
    CreatedOn = DateTime.Now,
    Message = "This is distance annotation",
    Opacity = 0.7,
    PageNumber = 0,
    PenColor = 65535,
    PenStyle = PenStyle.Dot,
    PenWidth = 3,
    Replies = new List<Reply>
    {
        new Reply
        {
            Comment = "First comment",
            RepliedOn = DateTime.Now
        },
        new Reply
        {
            Comment = "Second comment",
            RepliedOn = DateTime.Now
        }
    }
};

Step 3: Add Annotation

Add the created distance annotation to the document using the Add method of the annotator object.

annotator.Add(distance);

Step 4: Save Document

Save the annotated document to the desired location on your system.

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

Step 5: Display Confirmation

Finally, display a message confirming the successful saving of the annotated document.

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

Conclusion

Adding distance annotations to documents using GroupDocs.Annotation for .NET is a straightforward process. By following the steps outlined in this tutorial, you can enhance your documents with valuable annotations, facilitating better collaboration and communication.
