Are you looking to add watermarks to your documents seamlessly using .NET? Look no further! GroupDocs.Watermark for .NET is a powerful and easy-to-use library that allows you to manage watermarks in various document formats. Whether you’re working with PDFs, Word documents, or images, this tool has got you covered. In this tutorial, we’ll walk you through the process of loading a document from a stream and adding a watermark step by step. So, let’s dive right in!

Prerequisites

Before we start, make sure you have the following set up:

  1. Visual Studio: Any recent version of Visual Studio will work fine.
  2. .NET Framework: Ensure you have .NET Framework 4.0 or higher installed.
  3. GroupDocs.Watermark for .NET: You can download it from here.
  4. Basic Knowledge of C#: Familiarity with C# and object-oriented programming concepts will be helpful.

Import Namespaces

To use GroupDocs.Watermark in your project, you’ll need to import the necessary namespaces. This will enable you to access the library’s features without any issues.

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

Step 1: Setting Up Your Project

First things first, you need to set up your project in Visual Studio. Here’s how you do it:

  1. Create a New Project: Open Visual Studio and create a new C# Console Application project.
  2. Install GroupDocs.Watermark: Install the GroupDocs.Watermark library via NuGet Package Manager. Simply search for GroupDocs.Watermark and install it.

Step 2: Define Document Paths

Next, you need to define the paths for your document and the output file where the watermarked document will be saved.

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

Replace "Your Document Path" with the actual path of the document you want to watermark and "Your Document Directory" with the directory where you want to save the watermarked document.

Step 3: Load the Document from a Stream

Now, let’s load the document from a stream. This involves opening the document as a stream and then using the Watermarker class from the GroupDocs.Watermark library to manage it.

using (Stream document = File.OpenRead(documentPath))
using (Watermarker watermarker = new Watermarker(document))
{
    // Your code to manage watermarks will go here
}

This code snippet ensures that the document is opened as a stream and the Watermarker class is initialized with this stream. The using statements ensure that resources are properly disposed of after use.

Step 4: Create and Add a Watermark

Creating a watermark is straightforward with GroupDocs.Watermark. In this example, we’ll create a simple text watermark.

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

Here, we create a TextWatermark object with the text “Test watermark” and specify the font details. Then, we add this watermark to the document using the Add method of the Watermarker class.

Step 5: Save the Watermarked Document

Finally, save the watermarked document to the specified output path.

watermarker.Save(outputFileName);

This code saves the document with the newly added watermark to the outputFileName path you defined earlier.
