    public static void main(String[] args) {
        // Initialize watermarker with your document path
        Watermarker watermarker = new Watermarker("path/to/your/document.docx");
    }
}

Implementation Guide

Let’s break down the process of adding a watermark into manageable steps.

Load Word Document Feature

Overview: This feature demonstrates how to load a Word document using GroupDocs.Watermark with specific load options.

Step 1: Create Load Options

import com.groupdocs.watermark.options.WordProcessingLoadOptions;

WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();

Step 2: Initialize Watermarker

Watermarker watermarker = new Watermarker("YOUR_DOCUMENT_DIRECTORY/document.docx", loadOptions);

Explanation: The loadOptions parameter allows customization for loading documents, such as specifying password protection.

Create Text Watermark Feature

Overview: Here, we create a text watermark with custom font and color settings.

Step 1: Define the Watermark

import com.groupdocs.watermark.watermarks.Color;
import com.groupdocs.watermark.watermarks.Font;
import com.groupdocs.watermark.watermarks.TextWatermark;

TextWatermark watermark = new TextWatermark("Watermark text", new Font("Arial", 19));

Step 2: Set Watermark Color

watermark.setForegroundColor(Color.getRed());

Explanation: The foregroundColor method sets the color of your text watermark.

Configure Watermark Section Options Feature

Overview: This feature configures options for applying a watermark to specific sections of a Word document.

Step 1: Define Section Options

import com.groupdocs.watermark.options.WordProcessingWatermarkSectionOptions;
import com.groupdocs.watermark.options.WordProcessingLockType;

WordProcessingWatermarkSectionOptions options = new WordProcessingWatermarkSectionOptions();

Step 2: Lock the Section

options.setSectionIndex(0);
options.setLocked(true);
options.setLockType(WordProcessingLockType.ReadOnlyWithEditableContent);

Explanation: The setLocked method ensures that only specific sections can be edited, while others remain protected.

Add Watermark to Document Feature

Overview: This step involves adding the configured watermark to your document and saving it.

Step 1: Initialize Components

Ensure you have initialized the watermark, options, and watermarker.

TextWatermark watermark = new TextWatermark("Your Watermark Text", new Font("Arial", 19));
WordProcessingWatermarkSectionOptions options = new WordProcessingWatermarkSectionOptions();

Step 2: Add Watermark to Document

watermarker.add(watermark, options);

Step 3: Save the Document

watermarker.save("YOUR_OUTPUT_DIRECTORY/document.docx");

Explanation: The save method writes the changes back to a new file in your specified directory.

Practical Applications

  • Document Security: Prevent unauthorized copying or sharing by adding watermarks.
  • Branding: Use custom logos and text to reinforce brand identity across all documents.
  • Version Control: Differentiate between document versions with version-specific watermarks.
  • Legal Documents: Secure sensitive information in legal documents before sharing.

Performance Considerations

When working with large Word documents, consider the following tips:

  • Optimize memory usage by processing documents in sections if possible.
  • Use efficient data structures and algorithms to minimize resource consumption.
  • Regularly monitor application performance and adjust configurations as needed.
