Easily Add Watermarks: Python Watermarking for Excel

GroupDocs.Watermark for Python via .NET is a library that makes it easy to add watermarks to many business file types. Follow these steps to quickly add watermarks to your documents in Python:

Get Started with Watermarking: Begin by creating an instance of the Watermarker class. Pass your Excel file (as a path or stream) to the constructor to open it for watermarking.
Create Your Watermark: Make a Watermark object with your desired text and settings. You can add watermarks to any page or even to document elements like headers or attachments.
Customize the Watermark: Adjust the watermark’s size, position, font, color, and alignment to fit your needs. This helps your watermark look just right in your document.
Apply and Save: Use the Watermarker method to add your watermark(s) to the document. Save the result, ideally to a new file for safety.

    # Create a text watermark object
    font = gww.Font("Arial", 36.0)
    watermark = gww.TextWatermark("top secret", font)
    watermark.foreground_color = gww.Color.red
    watermark.horizontal_alignment = gwс.HorizontalAlignment.CENTER
    watermark.vertical_alignment = gwс.VerticalAlignment.CENTER
    watermark.opacity = 0.4

    watermarker.add(watermark)
