Creating a Realtime PDF Annotation and Commenting System

Viewing a PDF directly in a web app is steadily becoming mainstream. PDFTron’s WebViewer, the leading, most reliable javascript PDF viewer, is now powering hundreds of apps around the web.

After viewing, the next step for many apps is enabling users to annotate the PDFs and communicate about them in real time, directly in the browser. WebViewer has indeed always supported this, because by importing and exporting annotations and comments using the standard PDF XML comment format, annotations can be instantly synchronized between users.

In this tutorial, we will step you through this process by

  • Setting up a new WebViewer instance
  • Synchronizing annotations between the clients and a server
  • Authenticating users, and enforcing permissions

Semantic Content Recognition in PDF

Semantic content recognition is the ability to identify components of a document by their “class” – that is if any particular content constitutes a title, subtitle, section, paragraph, word, figure, caption, table, etc. This is a problem, that despite decades of research, remains open. Available solutions are unreliable and are far, far behind the ability of a human being.

At the 2015 PDF Technical Conference, PDFTron’s CTO gave a presentation addressing the problem of semantic content recognition in PDF. The presentation gives an overview of the problem itself, why it has been such a hard problem to solve, and how the industry as a whole might organize itself to finally develop solutions that perform with the same accuracy as a person.

pdf.js: Interesting Project, Incorrect Rendering

pdf.js is a well known project for rendering PDF documents directly in the browser. In that sense, it is similar to our recently announced PDFNetJS. While pdf.js is interesting project, and may be a reasonable choice in some very specific situations, it has a number of serious problems that make it unreliable for any situation where PDF rendering is important.
