Join CEO Duff Johnson and CTO Peter Wyatt as they discuss current and future PDF Association initiatives. Intended primarily for members, this session is also open to non-members.

PDFs in the wild offer a bewildering amount of variation in syntax, features and structure.  For those building parsers or evaluating parsers, it is critical to have a broad coverage corpus available to assess and discover distributions of issues “in … Read more

Was hat sich seit den letzten PDF Days beim PDF-Export mit Bordmitteln von Microsoft Office oder LibreOffice getan? Die Erstellung von vollständig barrierefreien PDF-Dokumente nach PDF/UA-Standard ist nach wie vor nicht möglich und erfordert eine Nachbereitung. Aber von Jahr zu … Read more

We will examine how specific problems are handled in these (not so) similar processes. Sometimes PDF/A validation can be more complex than PDF/A conversion, and in other cases, is it the other way around. What makes a document difficult to … Read more

At the moment WCAG validation is a legal requirement, while PDF/UA is not (unfortunately). In this talk we make an attempt to perform a gap analysis between these standards, taking PDF/UA-1 and Matterhorn 1.1 protocol as a basis and analyzing the … Read more

Two years after introducing Deriving HTML from PDF document, two years after implementing the core concept, after processing countless authored and un-authored pdf files we will share our experiences. To successfully adopt the idea, developers need to understand the implementation … Read more

This presentations sorts out digital signatures and e-Signing and describes the current status of e-Signing, with its non-interoperable, cloud based workflows. Can PDF turn e-Signing into an interoperable workflow? Can PDF carry proprietary data of the signing process and the … Read more

This talk will present the Arlington PDF Model as the first open access, vendor-neutral, comprehensive, specification-derived machine-readable definition of all formally defined PDF objects and their intra- and inter-object relationships. This represents the bulk of the latest 1,000-page ISO PDF … Read more

This talk will present industry-relevant outcomes from the DARPA-funded “SafeDocs” research program, as well as reviewing future directions. This research is aimed at reducing the attack surface of parsing software, and identifying and removing inherent weaknesses in the file formats, … Read more

We are used to setting text in color, but for decades operating systems and font formats supported only monochrome fonts where the font specifies only the shape of a glyph, but not its color. While you can apply color when … Read more

The presentation will first provide an overview of the current active open-source projects that deal with PDF rendering, creation, and manipulation. We will be looking at the activity of the projects (i.e. frequency of commits, number of contributors, history, etc.) … Read more

With mobile claiming more than 50% of total internet usage for the past 5 years, the way we interact and manipulate content must continue to adapt. For all a lot of publishers, PDF is still the format of choice. But, … Read more

Since the entry of 3D to the PDF specification, usage has been dominated by the AEC industry. Today, the way we use, interpret and digest 3D models and embed 3D data has matured—mostly attributed to the exponential advancements in technology. … Read more

The relationship between cryptography and PDF is one with a long history. PDF’s cryptography-related features have been through a number of significant revisions over the years, and PDF signatures have firmly established themselves as a replacement for paper signatures in … Read more

As we all know, PDF files are a structural marvel. There are many ways of constructing a file while still maintaining the same visual result. This is a blessing, but also a curse. This variety has to be accounted for … Read more

Digital archives have to preserve not only the data formats, they also have to make sure that proper viewer technology is available in the future. For most paper like formats this is solved by PDF/A. Email has replaced paper as the … Read more

This presentation will outline the current development of PDF/R and the state of  research for adding new, highly efficient image codes to future PDF versions for smaller PDFs, faster network transfers and more.

Tagged, accessible PDF documents are already part of the standard requirements of many companies – partly due to legal obligations, but increasingly also under a moral aspect. This requirement already arrived in most sectors, that’s for sure, but will increase … Read more

Ever-increasing demand for productivity and faster time to delivery is increasing awareness and adoption of Low-Code application development by IT teams and “Citizen IT”. This trend is disrupting traditional patterns of software development and is shifting development towards cloud-based low-code … Read more

Digital signatures and PDF are an increasingly popular combination for digitizing paper-based business processes. While the focus of most signature products and solutions is on the creation of the signature itself, the correct validation of signatures contained in PDF is … Read more
