Overview

You’ll learn how to embed a modern WordArt-style text watermark within an Excel document, customizing it for specific worksheets and enhancing its appearance with font settings.

Step 1: Define Paths and Initialize Load Options

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

Step 3: Define and Configure the Text Watermark

Set up a TextWatermark object with desired font properties to create your WordArt effect:

TextWatermark textWatermark = new TextWatermark("Confidential", new Font("Arial", 24));
textWatermark.ForegroundColor = Color.LightGray; // Example of customization

Step 4: Configure Watermark Options for the Worksheet

Specify which worksheet to target and apply WordArt styling:

SpreadsheetWatermarkModernWordArtOptions options = new SpreadsheetWatermarkModernWordArtOptions();
options.WorksheetIndex = 0; // Targeting the first worksheet (index 0)

Step 5: Add Watermark and Save the Document

Add your configured watermark to the document and save it:

watermarker.Add(textWatermark, options);
watermarker.Save(outputFileName);

Troubleshooting Tips

  • Ensure paths are correctly specified to avoid file not found errors.
  • Verify font compatibility across different systems for consistent appearance.
