Krita/Roadmap22

Overall goals

* stability
* performance

Use-cases

* We want to support  comic book artist fully
* We want to make it possible for the blender team to use Krita in their next project

For the comic-book artist we need:

* out-of-gamut preview in the image and in the color selector
* lock layer transparency (boud)
* improved memory usage and performance
* eps and psd support
* improved palette-based color selector interface

For blender we need:

* improved palette-based interface (see above)
* 10000x4000 multi-layered images with good performance
* big brushes (100-250 pixel radius) with good performance
* extensive compatibility with openexr

Bugs

I have gone through our bug backlog and assigned most bugs to the most likely person to fix the issues :-). [| Please take a look at it].

Commitments

Boudewijn

~~lock layer transparency (gui done, need to integrate icon, work out a way to preserve transparency in KisPainter, loading and saving or the property)~~
Fix bugs as they arrive. My goal is to be be under 20 known bugs for 2.2
fix serialization of the paintops, so stroke recording can work again. This might entail some refactoring, and ies in with Sven's preset work. Maybe something for the sprint?
finish my mypaint brush-compatible brush engine.
psd, gif support
gui polish

Cyrille

finish the CTL colorspace, that include optimizations, and full support for operations
finish merging of dynamic brush concepts into normal brush, that include the coloring options and angles, would probably an opportunity to look at some of the issues
keep polishing Shiva support, and GHNS integration
unit testing of pigment's operations (especially the one that are a bit broken, like convolution)

File support:

I want EXR to be a top class citizen in Krita, support for 16bit and 32bit, full CM (and probably layers if someone from blender is willing to answer a few questions and provide a test file)
since we are getting rid of GraphicsMagick, it's probably a good idea to work on replacing some of the filter as well, from those, my priorities would be ppm and jpeg2000

Color choosers:

I want to ditch that beep dialog :) We need a great color dialog
I have been thinking about a "digital color mixer" for a while, you will know more soon, since I think that the first thing I want to do after my PhD work is done ! I need fun !

Lukas

Paintops (some are thesis related):

implement new paintops: experimental, softbrush, particle brush
unify my paintops GUI, work with Cyrille and use sensors and share color dialog
brush outline should be QPainterPath , remove KoViewConvertor from paintops this way
help to port paintops for presets saving/loading

For Krita 2.3

3D brush needs shadows
finally look at the Emanuelle's work of Kubelka-Munk color composition
GLSL, OpenGL optimizations
all we came up during brainstorm with our community and David Revoy (UI fixes, speed-ups where can I do something) [see Action plan for details]

Sven

finish paintop presets (might interfere with the work from Boud or Lukas, so that needs more discussion)
adding shape layer implementation to the various visitors
get toolbox to work correctly with different layers
create flake shapes with Krita shape tools

Dmitry

finish layer merging refactoring, add synchronization between image and ui
add some parallelization to the merger
fix extent() bug in tiles3
add swapper to tiles3
(?) clone parallelization from merger to KisPrescaledProjection

Ed

Port Perspective Transformation tool
Improve convolution
