The PDF Hackathon is a technical and hands-on event where attendees will work in groups to find answers to their PDF questions. These questions might be related to any of the callas products or to more general PDF topics. Attendees will dig deep into the callas products or into PDF structures. Bringing one’s own laptop will be necessary. The idea of the PDF Hackathon is to bring together experts in different fields and to have an immediate and intense exchange of expertise.
