Prerequisites

Before we dive into the step-by-step guide, let’s ensure you have everything you need:

  1. Groupdocs.Watermark for .NET: Download the latest version from here.
  2. .NET Framework: Ensure you have .NET Framework installed on your machine.
  3. Development Environment: A development environment like Visual Studio.
  4. License: You can opt for a free trial or purchase a temporary license.

Import Namespaces

First things first, you need to import the necessary namespaces in your project. These are essential for accessing the classes and methods provided by Groupdocs.Watermark.

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

Step 1: Set Up Your Project

Open your development environment and create a new .NET project. This can be a console application or any other type that suits your needs.

You need to add the Groupdocs.Watermark package to your project. This can be done via NuGet Package Manager. Run the following command in the NuGet Package Manager Console:

Install-Package GroupDocs.Watermark

Step 2: Load the Word Document

Define the Document Path

Specify the path to your Word document. This will be the document where you want to add the watermark.

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

Set Load Options

Create an instance of WordProcessingLoadOptions to load your Word document with specific options.

var loadOptions = new WordProcessingLoadOptions();

Step 3: Create the Watermark

Initialize Watermarker

Using the Watermarker class, load the document with the specified load options.

using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Further steps will be inside this using block
}

Define Watermark Properties

Create a TextWatermark instance with your desired text, font, and color.

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

Step 4: Apply Watermark to All Pages

Set Watermark Options

Define WordProcessingWatermarkPagesOptions and set the IsLocked property to true to lock the watermark. This ensures the watermark cannot be removed easily.

WordProcessingWatermarkPagesOptions options = new WordProcessingWatermarkPagesOptions();
options.IsLocked = true;
options.LockType = WordProcessingLockType.AllowOnlyFormFields;

Optional: Add Password Protection

If you want to add an extra layer of security, you can set a password for the watermark.

// To protect with password
// options.Password = "7654321";

Add the Watermark

Use the Add method of the Watermarker class to add the watermark to the document with the specified options.

watermarker.Add(watermark, options);

Step 5: Save the Document

Finally, save the modified document to the specified output file.

watermarker.Save(outputFileName);
