Prerequisites

Before we dive into the details, ensure you have the following:

  1. Groupdocs.Watermark for .NET: Download it here.
  2. .NET Framework: Make sure you have .NET Framework installed on your machine.
  3. A Word Document: Have a Word document ready that you want to add watermarks to.
  4. Development Environment: Visual Studio or any other .NET compatible IDE.
  5. Temporary License: Obtain a temporary license for Groupdocs.Watermark.

Import Namespaces

To get started, import the necessary namespaces into your project. This is a crucial step to ensure that all functionalities of Groupdocs.Watermark are available.

using GroupDocs.Watermark.Common;
using GroupDocs.Watermark.Contents.Image;
using GroupDocs.Watermark.Contents.WordProcessing;
using GroupDocs.Watermark.Options.WordProcessing;
using GroupDocs.Watermark.Watermarks;
using System.IO;
using System;

Now, let’s break down the process into manageable steps.

Step 1: Setting Up Your Project

First, set up your project in your preferred IDE. Create a new .NET project and install the Groupdocs.Watermark library.

dotnet add package GroupDocs.Watermark

Step 2: Load the Word Document

Load the Word document that you want to watermark. Ensure the path to your document is correct.

string documentPath = "Your Document Path";
string outputFileName = Path.Combine("Your Document Directory", Path.GetFileName(documentPath));
var loadOptions = new WordProcessingLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Your code will go here
}

Step 3: Create the Watermark

Create a text watermark that you will apply to the images in the Word document. Customize the text, font, size, and alignment to suit your needs.

TextWatermark watermark = new TextWatermark("Protected image", new Font("Arial", 8));
watermark.HorizontalAlignment = HorizontalAlignment.Center;
watermark.VerticalAlignment = VerticalAlignment.Center;
watermark.RotateAngle = 45;
watermark.SizingType = SizingType.ScaleToParentDimensions;
watermark.ScaleFactor = 1;

Step 4: Retrieve Images from the First Section

Access the content of the Word document and find all images in the first section. This step is crucial as it identifies the images to which the watermark will be applied.

WordProcessingContent content = watermarker.GetContent<WordProcessingContent>();
WatermarkableImageCollection images = content.Sections[0].FindImages();

Step 5: Apply Watermark to Images

Loop through each image in the first section and apply the created watermark. This ensures that all images in the section are protected.

foreach (WatermarkableImage image in images)
{
    image.Add(watermark);
}

Step 6: Save the Document

Finally, save the watermarked document to the specified path. This completes the process of adding a watermark to section images in a Word document.

watermarker.Save(outputFileName);
