Linux Color Management Hackfest 2012

Brno, Czech Republic, Europe @ Red Hat Czech office

9th - 12th November 2012

Goals

This is a cross-desktop event that will focus on improving the state of color management on Linux desktops.

  • On demand ICC profile distribution
    • We want to make a lot of this stuff automatic, so that the user doesn't deal with .icc profiles directly. This makes it important to integrate all applications with a CM stack with color management enabled by default.
  • Color management for displays
    • 2D LUT "temperature" correction now works well, but with high gamut displays we're doing to need to do something more advanced in the compositor. This means a lot more moving parts and levels in our stack.
  • Color management for cross platform printing (libCmpx/PDF)
    • Or if this isn't suitable for GTK/cairo, how easy to re-implement.
  • Color management inside toolkits and libraries (Qt, GEGL, Cairo, Wayland)
    • We probably only want to CM parts of a window, for instance a PNG with an embedded profile, not the widget controls (assume sRGB for those).
  • Color management for applications, especially office apps (LibreOffice, KDE)

    • And getting rid of the [x] Enable Color Management checkboxes from everywhere.
  • Define application and workflow color management demands
    • I.e. discussions on what real world users (e.g. LO) want from a CMS in the real world.
  • Plan colour management API's and specifications for (Qt, GEGL, Cairo, Wayland)
    • wayland is a big change for our stack, and we want to design the CM to be a supported extension that works on all devices.

Travel & Accomodation

  • Brno has his own airport, but there are not many flights to it. There are direct flights from London/Stansted and Rome/Fiumicino and also Moscow. Another possibility to go to Brno would be the airport in Prague and then to Brno with train or bus. Another possibility is the airport in Vienna and also with bus or train to Brno.

  • A ticket for train costs from Prague arround 13€ and from Vienna arround 9€. Consider the bus, they are really comfortable and they have WLAN ;)

  • For using the public transport buy a ticket for 100+101 zones, consider to buy a 5day ticket for CZK 250 (~9€)
  • There are several hotels in Brno http://www.brno-hotel-avanti.eu/ , http://www.vista-hotel.cz/en/ or http://www.a-sporthotel.cz/hotel-brno-ubytovani/ . We try to get all participants in one hotel, to get special rates.

Sponsorship

OpenICC has as organization no budget, we try to win some sponsors, to re-imburse the travel costs. We can not guarantee that we can reimburse all travel costs! If you can be sponsored from another organization or your company, we would appreciate that.
