The PDF specification is critical to the PDF technology ecosystem and its stakeholders. “The spec” is the “law” that defines what a valid PDF file must be. While PDF does not have a reference implementation, the common practice of relying on reverse-engineering the work of others, or examining PDFs “from the wild” tends to lead … Read more
ISO 32005 is a new Technical Standard from WG9 (for which I am the ISO Project Leader) aimed at aligning and unifying the capabilities of the PDF 1.7 and PDF 2.0 tagset. This talk will introduce this concept and how it has been incorporated into 14289-2 along with the PDF Association driven Well-Tagged PDF (WTPDF) … 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 challenges, authors have to change their habits in producing pdf files. We will discuss gaps … 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 2.0 specification in a machine-readable text-based definition of the entire PDF DOM. It establishes a … 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 using the font, individual glyphs didn’t contain their own colors. The rising popularity of emoji … 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 if you want to traverse PDF files consistently and without inconveniencing your end users with … 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.
PDF is THE standard for print production and digitally delivered documents. Controversial? Perhaps, but the fact remains that PDF continues to see more adoption every year. It has cracked open transaction print while becoming the lingua franca of direct mail, book printing, and publishing. This fact along with the work of the PDF standards committees … Read more
The term Automated Document Factory (ADF) might sound familiar, especially if you have worked in or around print over the last three decades. For the printing industry, an Automated Document Factory (ADF) was the mainstay of the 1990s to solve print processing challenges. As the sophistication of both print devices and software has increased, an … Read more
Come and learn how an idea becomes a standard! We’ll look at some recent work driven by the PDF Association to advance the state of the art in PDF technology and the process it undergoes to become an ISO standard.
