Krita Community Wiki

This Community Wiki is intended for those who are making and improving Krita, such as programmers and designers. Users of Krita can check out getting started guides on, the Userbase wiki, and the manual. If you have questions, you can ask on the Krita Forums, or hop on #krita IRC!

Repository Information

There are two versions of Krita in development: 2.9, which is the stable branch and based on Qt4 and merged with Calligra, and 3.0 pre-alpha, which is based on Qt5.


Details are listed in the Linux build instructions.

Build Instructions

The full set of Krita 3.0 master dependencies:


The full set of dependencies for Krita 3.0 pre-alpha:

  • Qt 5, at least 5.3 is required, but the newer the better. You need the following components:
    • Core
    • Gui
    • Widgets
    • Xml
    • Network
    • PrintSupport
    • Svg
    • Test
    • Concurrent
    • OpenGL (optional, but really, really recommended)
    • Quick (optional, for sketch/Gemini)
    • DBus (optional)
    • X11Extras (only on Linux)
  • The following required packages
    • Eigen3
    • Exiv2
    • lcms2
    • GSL
    • Boost (headers and the boost system library)
    • zlib
    • libtiff
    • libpng
    • libjpeg
    • perl (need to check if this is really true, I doubt it)
  • The following optional packages
    • SharedMimeInfo
    • Poppler
    • OpenEXR
    • pthreads (for G'Mic)
    • openmp (for G'Mic)
    • curl (for G'mic)
    • libraw
    • fftw3 (for G'mic and performance improvements)
    • Vc 0.7
    • OpenColorIO

Krita can be built successfully omitting several optional packages. KIO is for optional thumbnail integration with Dolphin. QtDeclarative is for Krita Sketch. Poppler is for PDF import. GSL is for the transform tool and eventually the magnetic lasso tool. Vc is for faster SIMD accelerated painting, and is necessary for a usable painting experience on anything but the smallest canvases. SharedMimeInfo is for determining file types. If you want to build Krita without these features, you can omit the package.


For 2.9, David Revoy's guide is the best available: Building Krita for Cats

These are technical notes on the insides of Krita.

Design Notes




This is an index of work sponsored by the Krita community and the Krita Foundation. Note that the Krita Foundation (Stichting Krita) has been instrumental in fundraiser efforts around Krita. The first program, executed during the 2009-2010 timeframe, allowed Lukáš Tvrdý to work full-time on Krita for 24 weeks. This made a massive difference for Krita, solving hundreds of bugs and improving performance and usability of the canvas and many brushes to the level where Krita first became ready for (semi) professional use. Find more details here.

Subsequent fundraisers supported Dmitry Kazakov who brought openGL support to a new level and introduced advanced canvas operations like panning, mirroring and rotation and independent artist Timothee Giet who developed the "Comics with Krita" training DVD as well as a host of other video tutorials on Youtube.



The Krita team has two Wacom intuos tablets, two stylusses and two art pens. They are currently with:

  • Lukas Tvrdy: one tablet
  • Sven Langkamp: one tablet
  • Cyrille Berger: stylus art pen
