stamp_page_numbers
Number PDF pages
Use this when the user wants to add page numbers to a PDF, number the pages of a PDF, put "Page 1 of 10" in a footer or header, or skip numbering the cover page. Takes one attached PDF, a format with {n} (this page's number) and optional {total} (the last number), one of six positions, start number, pages to skip at the start, font size and margin, and returns a new PDF. Each stamp is checked again in the new file before the link is given. Does not open password-protected PDFs, does not draw non-Latin scripts or emoji, and does not change the page content under the number. Do not use for Bates numbers (use stamp_bates_numbers).
