原文外掛簡介
PDF Ink Lite can add a watermark to every page of your sold PDF file(s). It can also password and permissions protect your PDFs. The watermark is customizable with font face, font color, font size, vertical placement, and text.
PDF Ink Lite watermarks PDF products when downloaded using WooCommerce download links, and works similarly for Download Monitor and Easy Digital Downloads.
Since the watermark is added when the download button is clicked (either on the customer’s order confirmation page or email, or account page), the watermark can include customer-specific data such as the customer’s first name, last name, and email.
Upon purchase download link, this plugin uses the open source TCPDI and TCPDF libraries to parse and customize your PDF.
(FYI – This plugin used to be called WaterWoo. It’s been in active development since 2014!)
Features:
Choice of font face, color, size and placement (a horizontal line of text, centered anywhere on the page)
Included font types cover most languages, and the plugin is internationalized
Dynamic customer data inputs (customer first name, last name, email, order paid date, and phone) to customize PDFs on-the-fly
Add a password to your PDF, and/or anti-copy, anti-print protections
Watermark only designated PDF downloads (as specified by you), or all PDF downloads from your site
Watermark is applied to all pages of the PDF (upgrade to choose pages)
Accommodates different page/paper sizes, and PDFs with various page sizes (letter, A4, legal, etc)
Secure & encapsulated: PDF Ink hooks into e-commerce download link clicks and checks for PDFs and maybe marks them – that’s it!
PDF Ink Lite is the only watermarker for WordPress which includes necessary libraries (so you don’t have to ask your host to load them), is compatible with PHP 8+, and watermarks newer versions of PDFs (not just older versions).
For better PDF coverage and many more options, check out PDF Ink, the full version of PDF Ink Lite.
