Introduction

In this tutorial, we will explore how to add a watermark to shape images within Word documents using GroupDocs.Watermark for .NET. Watermarking is a crucial aspect of document protection, especially when dealing with sensitive or confidential information. By adding watermarks to shape images, you can ensure the integrity and security of your documents.

Prerequisites

Before we begin, ensure you have the following:

1. GroupDocs.Watermark for .NET: Download and install the GroupDocs.Watermark library from the download page.
2. Document: Prepare the Word document where you want to add the watermark.
3. Development Environment: Set up your preferred .NET development environment.

Import Namespaces

Before writing the code, make sure to import the necessary namespaces:

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

Step 1: Load the Document

First, define the path to your document and specify the output file name:

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

Step 2: Initialize Watermarker

Instantiate a Watermarker object by providing the document path and optional load options:

var loadOptions = new WordProcessingLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Add watermarking logic here
}

Step 3: Create Text Watermark

Define the text watermark with desired properties such as text, font, alignment, rotation, sizing, etc.:

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: Apply Watermark to Shape Images

Iterate through the document sections and shapes to identify shape images and add the watermark:

WordProcessingContent content = watermarker.GetContent<WordProcessingContent>();
foreach (WordProcessingSection section in content.Sections)
{
    foreach (WordProcessingShape shape in section.Shapes)
    {
        if (shape.HeaderFooter == null && shape.Image != null)
        {
            shape.Image.Add(watermark);
        }
    }
}

Step 5: Save the Document

Save the document with the added watermark to the specified output file:

watermarker.Save(outputFileName);
