Introduction

Are you looking to add a watermark to specific pages in your Word documents, but want it to be locked so that it cannot be easily removed or edited? You’re in the right place! In this tutorial, we will guide you through the process of adding a locked watermark to specific pages in Word documents using GroupDocs.Watermark for .NET. This powerful library makes it easy to apply, manage, and customize watermarks on a variety of document types. Whether you’re a developer or just someone who needs to secure their documents, this guide will walk you through each step in a straightforward manner.

Prerequisites

Before we dive into the tutorial, let’s ensure you have everything you need:

  1. GroupDocs.Watermark for .NET: You can download the latest version.
  2. Development Environment: An IDE like Visual Studio.
  3. Basic Knowledge of C#: Familiarity with C# programming will be helpful.
  4. Document to Watermark: A Word document (.docx or .doc) that you want to add a watermark to.

Import Namespaces

First, you need to import the necessary namespaces in your C# project. These namespaces provide access to the classes and methods required to work with GroupDocs.Watermark.

using GroupDocs.Watermark.Options.WordProcessing;
using GroupDocs.Watermark.Watermarks;
using System.IO;
using System;

Now that we’ve got the prerequisites covered and the necessary namespaces imported, let’s break down the process step by step.

Step 1: Load the Word Document

To begin with, you need to load the Word document you want to add a watermark to. This can be done using the Watermarker class along with WordProcessingLoadOptions.

string documentPath = "Your Document Path";
var loadOptions = new WordProcessingLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Continue to the next steps
}

Step 2: Create the Text Watermark

Next, create a text watermark. You can customize the text, font, color, and other properties according to your requirements.

TextWatermark watermark = new TextWatermark("Watermark text", new Font("Arial", 19));
watermark.ForegroundColor = Color.Red;

Step 3: Configure Watermark Options

To apply the watermark to specific pages and lock it, configure the WordProcessingWatermarkPagesOptions. Here, you specify the page numbers where the watermark should appear and set the locking options.

WordProcessingWatermarkPagesOptions options = new WordProcessingWatermarkPagesOptions();
options.PageNumbers = new int[] { 1, 3 }; // Specify the pages
options.IsLocked = true; // Lock the watermark
options.LockType = WordProcessingLockType.AllowOnlyComments; // Set lock type
// To protect with a password
// options.Password = "7654321";

Step 4: Add the Watermark to the Document

With your watermark and options configured, you can now add the watermark to the document.

watermarker.Add(watermark, options);

Step 5: Save the Document

Finally, save the document with the watermark applied. Choose an appropriate output path and save the file.

string outputFileName = Path.Combine("Your Document Directory", Path.GetFileName(documentPath));
watermarker.Save(outputFileName);
