Accessible PDF Stamping

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…

Selling Customized Gift Certificates: A Case Study

When it’s impossible to have customers in the store and clients face-to-face, how can money be made? One fairly obvious, and earnest-enough, method is by selling your reputation on paper: gift certificates and gift vouchers. For many businesses there is a real opportunity for income here. And many (future) loyal customers understand that purchasing gift certificates is a way to support businesses right now. They know that by making these purchases, when the Great Shutdown begins to heal, their community might look closer to how it did in 2019.

New Plugins!

This month there is loads more news than usual, and not much of it is easy to bear. Here in California we’ve been ordered to stay home now for more than a week. I’ve distracted myself by typing lots and lots code. It’s about time I addressed your ongoing request for a PDF watermarker that preserves internal links such as table of contents. For many of you with longer PDFs, these page indexes are crucial. While my proposed solution is more expensive and mildly more complicated to install than WaterWoo & EDDiMark, it offers improved PDF parsing/writing and heftier encryption, as well as backing by the PDF gurus at SetaSign. Bottom line: if it is essential your PDF keep its internal links, you want a -Stamper plugin, not WaterWoo or EDDiMark.

Adding Custom Fonts to EDDiStamper

All three new Stamper plugins (EDDiStamper, PDF Stamper, and Download Monitor Stamper) come with the three standard PDF fonts: Helvetica, Times New Roman, and Courier. Not much to get excited about, I know. Whereas EDDiMark and WaterWoo (plugins based on TCPDF, not SetaPDF-Stamper) have built-in font uploaders with more instant gratification, the integration with Seta is a bit more complicated, and so you’ll need to use a little code. Whether you add the code into a custom plugin, your child theme functions.php file, or by using the more plug-n-play Code Snippets plugin doesn’t matter. Before using the following example code, we have started by creating a “fonts” folder inside the wp-content/uploads/eddistamper/ folder. We put our Comic Sans (yes!) TTF file inside the fonts folder. You can see that path reflected in line 6 of the code below. So, put the continue reading…
