Load Document from Local Disk

Introduction

Watermarking documents is essential in today’s digital age to ensure content protection, ownership assertion, and confidentiality. Groupdocs.Watermark for .NET is a powerful library that allows developers to add, search, and manage watermarks in various document formats. In this tutorial, we’ll walk through the process of using Groupdocs.Watermark for .NET to add watermarks to your documents with detailed step-by-step instructions.

Prerequisites

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

  1. Visual Studio Installed: You’ll need Visual Studio or another compatible .NET IDE.
  2. Groupdocs.Watermark for .NET: Download the library from the download link.
  3. .NET Framework: Ensure you have .NET Framework 4.6.1 or higher installed.
  4. A Sample Document: Prepare a sample document to test the watermarking process.

Import Namespaces

To get started, you’ll need to import the necessary namespaces in your project. These are essential for accessing the classes and methods required for watermarking.

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

Step 1: Load Document from Local Disk

First, you need to load the document from your local disk. This document will be the one to which you will add a watermark. Define the path of the document you want to watermark.

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

Step 2: Initialize Load Options

Next, initialize the load options. For instance, if you’re working with a Word document, you’ll use WordProcessingLoadOptions.

var loadOptions = new WordProcessingLoadOptions();

Step 3: Create and Configure Watermarker

Now, you’ll create an instance of the Watermarker class. This instance will be used to manage and apply watermarks to your document.

using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // This block will contain further steps to add and save the watermark
}

Step 4: Create a Watermark

Create a text watermark. This watermark can contain any text you choose. Here, we will use “Test watermark”.

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

Step 5: Add Watermark to the Document

Add the created watermark to the document using the Add method of the Watermarker class.

watermarker.Add(watermark);

Step 6: Save the Watermarked Document

Finally, save the watermarked document to the specified path.

watermarker.Save(outputFileName);
