It’s pretty easy to create a QR code that opens a PDF. Google that and you’ll find a million results. But it’s a little trickier to add a QR code to an existing PDF. The TCPDF Bridge WordPress plugin can do that now! We’ve added settings to the TCPDF Bridge plugin settings panel to make adding different barcode types (including QR codes) to your PDFs, whether for retail, pharmacy, or industrial purposes. Since the plugin allows you to accept some user input before your PDF file is downloaded, you can even include that data in your barcode! Completely customized barcodes added on-the-fly to your PDFs, as they are downloaded… that’s pretty cool 😎 Here are the types of barcodes supported by TCPDF Bridge: CODE 39. Also called Alpha39, Code 3 of 9, Code 3/9, Type 39, USS Code 39, or continue reading…
PDFs are a fantastic way to share documents – they preserve formatting, are widely compatible, and can even be compressed for easy transmission. But what if that PDF contains sensitive or monetized information? The Portable Document Format (PDF) offers some security, which when stacked can be quite effective. These include: Watermarks. Adding content to a PDF, especially content customized to the end-user (such as their name and other personally-identifying information like phone/email, can not only personalize a PDF, but also thwart unauthorized sharing. Keep reading to find out how to make your watermarks most effective against PDF theft. Encryption. Arcfour RC4, and the superior 128-bit key or 256-bit AES encryption Passwording. User and owner passwords can be set. An owner password gives the holder full control over the PDF, including the ability to remove passwording entirely — share with caution! continue reading…
Many people and organizations put the extra care into their PDF documents to ensure they are usable by ALL humans, not just people with good vision and keyboard/mouse dexterity. What does this mean? It is often imperative documents be accessible due to accessibility codes and laws. So it must be very frustrating to have accessibility features removed by a PDF manipulation plugin! Unfortunately, the open-source PDF manipulation libraries I use for many of my plugins does not allow for robust or reliable PDF manipulation. Namely, TCPDI/TCPDF depends on being fed a syntactically correct PDF, and then because of the way objects are read flat into PHP memory during the process, certain PDF features in the stream are necessarily lost. Marking/passwording with TCPDI/TCPDF or FPDI/FPDF is lossy, no way around it. However, the SetaPDF library from SetaSign works differently by parsing continue reading…
Lately folks have been raising the alarm that passwords and content can be removed from PDFs. Unfortunately, this just isn’t news. When was the Internet a safe place to store or share documents? What does a PDF have in common with NASA, the Pentagon, Nasdaq, and most credit card companies? They are all demonstrably hackable. And if a multi-billion dollar organization can be hacked, you bet your bottom dollar your PDF can be, too. You can also bet that a
I’m getting too many emails about this to answer them all, sorry. Hopefully I can answer you here. I write and maintain WordPress plugins for a living. For ~8 years I have also provided and supported free plugins on the side. I provide two plugins in the free (open-source) WordPress.org plugin repository, both of which are well-loved and rated. As you may have noticed, they were abruptly removed by WordPress on January 24th. It was a surprise to me, too! Frankly I have been feeling burned out on supporting free software, so maybe this is a chance for me to at least say my piece. One has to think abstractly for it to feel rewarding, as in “I know people aren’t saying anything, but I imagine these plugins make the world better and peoples’ days easier.” I also feel like continue reading…
