Introduction

In today’s digital age, adding watermarks to documents has become essential for protecting intellectual property and ensuring brand integrity. Groupdocs.Watermark for .NET offers a robust solution for developers looking to embed watermarks into documents seamlessly. This comprehensive guide will walk you through the steps of saving a document with a watermark to the same file or stream using Groupdocs.Watermark for .NET.

Prerequisites

Before diving into the tutorial, ensure you have the following:

  1. Development Environment: Visual Studio installed on your machine.
  2. .NET Framework: Make sure you have .NET Framework 4.0 or later.
  3. Groupdocs.Watermark for .NET: Download and install the latest version from the site.
  4. License: Obtain a temporary or permanent license from here.

Import Namespaces

To start using Groupdocs.Watermark in your .NET project, you need to import the necessary namespaces:

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

Step 1: Set Up Your Project

Before we add watermarks to our documents, we need to set up our .NET project. Here’s how:

  1. Create a New Project: Open Visual Studio and create a new Console Application.
  2. Add Groupdocs.Watermark Reference: Right-click on the project in Solution Explorer, choose “Manage NuGet Packages,” and install the Groupdocs.Watermark package.

Step 2: Copy the Document to a New Location

To avoid altering the original document directly, it’s a good practice to copy it to a new location first. Here’s how you do it:

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

Step 3: Initialize the Watermarker

Now that we have our document copied, we can initialize the Watermarker class to add our watermark:

using (Watermarker watermarker = new Watermarker(outputFileName))
{
    // watermarking goes here
}

Step 4: Create and Add a Text Watermark

Next, we create a text watermark and add it to our document:

TextWatermark watermark = new TextWatermark("Test watermark", new Font("Arial", 12));
watermarker.Add(watermark);

Step 5: Save the Document

Finally, save the document with the watermark applied:

watermarker.Save();
