PDF is a file format everyone is using, but most people, including the majority of the hacker community, knows very little about how it works.
This lecture is intended as an introduction to the PDF file format. For the audience, knowledge about other file formats is helpful but not mandatory.
The file format will be explained in as much detail as fits in one hour, using self-generated "hello world" style examples as well as more complicated examples for selected PDF features. The covered areas include the following (no particular order yet):
brief history and overview to PDF versions (1.0 to 1.5, PDF/X, PDF/A)
standards and license issues
syntax and semantics overview of the file format
relationship PostScript and PDF
fonts
bitmap and vector graphics
strings, streams, compression, encryption
The ideal goal is to enable the listener to understand the structure of a given PDF by opening it in vi or a hex editor, and to get an idea about the effort that is needed to write a PDF generator or a PDF consumer application.
A short (and incomplete) overview to tools, applications and pointers to further information will be included in documentation to the lecture.
The lecture will be held in English unless there's nobody in the audience who doesn't understand German.
A preliminary version of the lecture has already been held at ICMP2.
A workshop to examine selected technical areas in more detail is possible after the lecture, if there's a timeslot left to fill.
