Step-by-Step Instructions

1. Load the Document Start by loading the Word document using Watermarker:

import com.groupdocs.watermark.options.WordProcessingLoadOptions;

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

2. Create and Configure a TextWatermark Create an instance of TextWatermark with your desired text, font, and color:

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

TextWatermark watermark = new TextWatermark("Confidential", new Font("Arial", 19));
watermark.setForegroundColor(Color.getRed()); // Set the color to red for visibility.

3. Lock the Watermark Ensure your watermark is locked across all pages:

import com.groupdocs.watermark.options.WordProcessingWatermarkPagesOptions;
import com.groupdocs.watermark.watermarks.WordProcessingLockType;

WordProcessingWatermarkPagesOptions options = new WordProcessingWatermarkPagesOptions();
options.setLocked(true);
options.setLockType(WordProcessingLockType.AllowOnlyFormFields); // Restrict modifications.

4. Add the Watermark to the Document Add your configured watermark:

watermarker.add(watermark, options);

5. Save and Close Save the document with the watermark applied and release resources:

Locking a Watermark in All Pages

Overview

Locking watermarks prevents easy removal, ensuring your content remains protected even if shared.

1. Create a TextWatermark Instance Initialize the watermark with specific text and font:

TextWatermark lockedWatermark = new TextWatermark("Locked", new Font("Arial", 19));

2. Configure Locking Options Set options to lock the watermark across all pages:

WordProcessingWatermarkPagesOptions lockingOptions = new WordProcessingWatermarkPagesOptions();
