Krita GSoC: Colour selectors with Colourspaces support

my last post was long ago, the reason were my exams which ended a week ago and which forced me to do some learning. But in the past week I started working on Krita again.

All selector types from this site are implemented now. All of them support colour spaces, which is important, if using cmyk. There is quite a difference in what you are probably used to, as you can see here:

This is of course still work in progress. I plan to change the layout of the selectors dynamically according to the space provided. For instance the horizontal slider of the wheel selector will be a vertical one, if the width is greater than the height. This way the widget will be very space efficient.

I also made the MyPaint shade selector colour space aware. Here is a direct comparison between cmyk at the top and rgb at the bottom.

As you probably see, this widget is not antialiased. It’s not as simple as setting a flag in Qt, but during programming the standard selectors, I’ve learned, how to make it antialiased. So in the final version there will certainly be a MyPaint selector with antialiased edges. If I have time, I will also happily implement some of these ideas.
