Add text stamps to PDF in C++

Add a text stamp to a PDF page and configure its font, color, position, and rotation using Aspose.PDF for C++.

Add a styled text stamp

1. Open the input PDF as a Document.
2. Create a TextStamp containing Sample Stamp.
3. Set background mode, position, and 90-degree rotation.
4. Use FontRepository to select Arial and configure the stamp text state.
5. Call AddStamp() on page 1.
6. Save the result with Save().
