Their goals include: making further improvements to accessibility support, implementing tiling support to allow infinite zoom, improving the support for PDF annotations, revamping the comics back-end and reviewing and integrating pending patches.
The hackfest brings together members of the GNOME Accessibility team, and Evince developers. It also involves a number of Google Summer of Code students.
The event could not have taken place without the support of the GNOME Foundation.
