Add Ellipse Annotation to Document

Introduction

In this tutorial, you’ll learn how to add an ellipse annotation to a document using GroupDocs.Annotation for .NET. This step-by-step guide will walk you through the process, ensuring that you understand each step clearly.

Prerequisites

Before you begin, make sure you have the following:

1. GroupDocs.Annotation for .NET: Make sure you have downloaded and installed GroupDocs.Annotation for .NET. You can download it from here.
2. IDE (Integrated Development Environment): You’ll need an IDE installed on your system, such as Visual Studio, to write and execute the code.

Import Namespaces

First, import the necessary namespaces to your 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: Set Output Path

Define the output path where the annotated document will be saved:

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

Step 2: Initialize Annotator

Initialize the annotator by providing the input document path:

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

Step 3: Create Ellipse Annotation

Create an instance of the EllipseAnnotation class and set its properties:

EllipseAnnotation ellipse = new EllipseAnnotation
{
    BackgroundColor = 65535,
    Box = new Rectangle(100, 100, 100, 100),
    CreatedOn = DateTime.Now,
    Message = "This is ellipse 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 4: Add Annotation

Add the ellipse annotation to the document:

annotator.Add(ellipse);

Step 5: Save Document

Save the annotated document to the output path:

annotator.Save(outputPath);

Conclusion

Congratulations! You’ve successfully added an ellipse annotation to a document using GroupDocs.Annotation for .NET. You can now integrate this functionality into your .NET applications to enhance document collaboration and communication.
