Put Image Annotation over Text

Introduction

In the world of .NET development, GroupDocs.Annotation offers a powerful solution for adding annotations to documents, making collaboration and document management more efficient. One common requirement is putting image annotations over text, which can be accomplished seamlessly using GroupDocs.Annotation for .NET.

Prerequisites

Before diving into the process of putting image annotations over text using GroupDocs.Annotation for .NET, ensure you have the following:

1. GroupDocs.Annotation for .NET Library: Download and install the library from here.
2. Development Environment: Set up a suitable development environment, such as Visual Studio or any other .NET IDE.
3. Document and Image Files: Prepare the document file (PDF, DOCX, etc.) and the image file you want to use for annotations.
4. Basic Understanding of C#: Familiarity with C# programming language is necessary to implement the code snippets provided in this tutorial.

Import Namespaces

Before proceeding with the annotation process, ensure you import the necessary namespaces in your C# project:

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

Step 1: Define Output Path

First, define the output path where the annotated document will be saved:

string outputPath = Path.Combine("Your Document Directory", "annotated_document.pdf");

Step 2: Initialize Annotator

Initialize the Annotator object by providing the input document path:

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

Step 3: Create Image Annotation

Create an ImageAnnotation object with the desired properties such as box dimensions, opacity, page number, image path, and z-index:

ImageAnnotation image = new ImageAnnotation
{
    Box = new Rectangle(100, 100, 100, 100),
    CreatedOn = DateTime.Now,
    Opacity = 0.7,
    PageNumber = 0,
    ImagePath = "image.png",
    ZIndex = 3
};

Step 4: Add Annotation

Add the image annotation to the document using the Add method of the Annotator object:

annotator.Add(image);

Step 5: Save Annotated Document

Save the annotated document to the specified output path:

annotator.Save(outputPath);

Step 6: Display Success Message

Display a success message with the path to the annotated document:

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

Conclusion

In conclusion, adding image annotations over text in .NET applications using GroupDocs.Annotation is a straightforward process. By following the step-by-step guide provided in this tutorial, you can efficiently annotate documents and enhance collaboration and document management capabilities in your .NET projects.
