Implementation Guide

In this section, we’ll walk through adding a text watermark to a Word document using GroupDocs.Watermark for .NET.

Adding Text Watermarks to Word Documents

Overview Adding a text watermark involves specifying the text, style, and position within the document. This feature is useful for branding or marking documents as confidential.

Step 1: Define Document Path and Output File Name

Start by defining the paths for your input and output files:

string documentPath = "YOUR_DOCUMENT_DIRECTORY\YourDocument.docx";
string outputFileName = Path.Combine("YOUR_OUTPUT_DIRECTORY", "WatermarkedDocument.docx");

Step 2: Load the Word Document

Use the Watermarker class to load your document:

using (Watermarker watermarker = new Watermarker(documentPath))
{
    // Further steps will be added here.
}

Step 3: Create and Configure the Text Watermark

Create a text watermark with specific settings:

TextWatermark watermark = new TextWatermark("Confidential", new Font("Arial", 36))
{
    RotateAngle = -45,
    Opacity = 0.5,
    ForegroundColor = Color.Red,
    HorizontalAlignment = HorizontalAlignment.Center,
    VerticalAlignment = VerticalAlignment.Center
};

Step 4: Add the Watermark to the Document

Add the configured watermark to your document:

watermarker.Add(watermark);

Step 5: Save the Watermarked Document

Save the changes to a new file:

watermarker.Save(outputFileName);

Troubleshooting Tips

  • Ensure all paths are correctly defined and accessible.
  • Check for any missing dependencies or incorrect library versions.
