What programming language for "Mark and add comments" on PDF?

David Ormes · February 21, 2018

What technology to adopt for "marking and adding comments" on PDF file? And save it back to same server it is loaded? We have an application built in PHP and jquerry. Need an expert opinion as we are not quite familiar with this.

Below is an example video for reference relating to our topic.

I expect there are many PHP libraries that can do what you need. I'm not a PHP dev, so I'll leave it to you to search for an appropriate one for your company. If for some reason PHP doesn't have an acceptable library, you could use one from another language. You could use a web service, command line tools, or something else that PHP can call to get the results from the other application.

I've only done this in .NET before and have used iText (Java and .NET support), iTextSharp (.NET only), and ABCpdf .NET 9 (.NET only). I also recall looking into Adobe PDF Library (C++, .NET, and Java support) and others but I don't remember what they all were. iText suited our needs.
