Implementation Guide

Now that we’ve covered the setup, let’s dive into implementing text watermarking.

Feature 1: Text Watermark Addition

Overview

Adding a text watermark involves loading your document and embedding custom text. This section will guide you through this process step-by-step.

Step 1: Load the Document

First, specify the path to your Word document:

string documentPath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "YourDocument.docx");

Ensure that documentPath points to a valid file location.

Step 2: Create and Configure the Text Watermark

Create an instance of TextWatermark, customizing its font, size, and content:

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

// Initialize text watermark with desired properties
TextWatermark watermark = new TextWatermark("Test watermark", new Font("Arial", 12));

This snippet demonstrates how to set the font and size of your watermark text.

Step 3: Add the Watermark to the Document

Use a Watermarker object to apply the watermark:

using (Watermarker watermarker = new Watermarker(documentPath))
{
    // Add watermark to document
    watermarker.Add(watermark);
}

Here, watermarker.Add() applies your configured watermark.

Feature 2: Saving Document with Watermark

Overview

After adding the watermark, you must save the modified document. This section will explain how to achieve that efficiently.

Step 1: Define Output File Path

Choose a directory and filename for saving:

string outputFileName = Path.Combine("YOUR_OUTPUT_DIRECTORY", Path.GetFileName(documentPath));

Ensure outputFileName does not overwrite existing files unintentionally.

Step 2: Save the Watermarked Document

Execute the save operation to store your watermarked document:

// Save the document with watermark
watermarker.Save(outputFileName);

This ensures that all changes are preserved in a new file.

Practical Applications

Use Cases for Text Watermarking:

  1. Document Protection: Mark sensitive documents as “Confidential” or “Draft.”
  2. Branding: Embed company logos or names across corporate documentation.
  3. Version Control: Distinguish between document versions with version numbers as watermarks.
  4. Collaboration: Clearly indicate authorship when sharing drafts among team members.

Integration Possibilities

Integrate GroupDocs.Watermark with other systems for automated workflows, such as batch processing or cloud storage solutions like AWS S3 or Azure Blob Storage.

Performance Considerations

To optimize performance:

  • Minimize file I/O operations by handling files in memory where possible.
  • Manage resources efficiently to prevent memory leaks, especially when dealing with large documents.
  • Follow .NET best practices for resource management and garbage collection.
