Rich Text Format (RTF) documents remain popular because they are lightweight, portable, and supported across many platforms and applications. Adding a text watermark is a useful way to mark documents as confidential, indicate draft status, or apply branding information. If you need to add text watermark to RTF using Python, this guide explains how to embed custom text directly inside the RTF structure. It also shows how to apply watermark to RTF in Python, allowing you to control font style, color, and placement for consistent watermarking across the entire file.

Steps to Add Text Watermark to RTF Using Python

1. Install GroupDocs.Watermark for Python via .NET using pip to enable text watermarking for RTF documents.
2. Import the necessary modules: groupdocs.watermark, groupdocs.watermark.watermarks, and groupdocs.watermark.common.
3. Open the RTF file by creating a Watermarker instance within a with block to ensure safe and reliable resource handling.
4. Set up a Font object by defining the preferred style and size for the watermark text.
5. Create a TextWatermark object that contains the watermark string along with the configured font settings.
6. Adjust the watermark’s appearance by customizing its color, alignment, and placement within the document.
7. Apply the watermark to the RTF file using the watermarker.add() method.
8. Save the processed RTF document to produce the final file with the embedded text watermark.

The watermarking library applies the text watermark across all pages or sections within the RTF file, ensuring that the watermark remains visible throughout the document. You can customize the font type, size, alignment, and color to match your formatting requirements. By following the steps provided, you can automate Python code to add text watermark to RTF and incorporate watermarking into your document-processing workflows. This approach is especially useful when generating reports, creating document batches, or applying classification labels, helping maintain consistent formatting without manually editing each RTF file.

Code to Add Text Watermark to RTF Using Python

After processing, the RTF document displays your text watermark across its pages, providing a clear indicator such as “Confidential,” “Draft,” or any custom message you choose. You can further refine the appearance by adjusting alignment, font size, opacity, or color to suit various layouts. This guide demonstrates how to insert text watermark in RTF using Python, offering a dependable way to enhance control, consistency, and organization in your RTF documents. Automated watermarking ensures accurate placement and reduces manual effort when preparing documents for internal use or distribution.
