Modify the sampled colours displayed by the Colour Sampler Tool to be concentric circles so that they are not obscured by the pen

Quick test. The design works well.

The compare bubbles are
The resize and thickness options are:
On / Off for outline is:

I feared, the ring design would become the thin inner outer circle of the initial post, which would have been a regression for me. But Carsten Hartenfels found a clever solution.

Technical note:
On my system (Windows 10 with Huion tablet attached) I have to minimize → maximize the Krita window after each change of the settings, otherwise the picker, triggered by the pen button, won’t work anymore.

The additional half-circles on the sides are actually both my idea and my implementation, you can see on the commits list. The settings were also implemented by me.

The technical side was implemented by him though, and he’s taking the control back for some more tweaks possibly to reenable the preview on hover (as @Lynx3d requested), so I’ll let him know. Also Carsten goes by @Drawpile here (since he also develops Drawpile).

I’d suspect that this is related to the settings dialog, not the setting. Try the following (starting from the state where it works):

1. Open the settings dialog. Don’t change anything, just press OK. Try to use the color picker with your pen button. How does it behave?
2. Switch to the color picker tool (e.g. by pressing P). In the Tool Options docker, change the Preview option to something else. Switch back to the brush tool (e.g. by pressing B). Try to use the color picker with your pen button again, how does it behave?

Sorry, then many thanks to you @tiar and to @Drawpile. The design and the customizability are making this picker stand out. I think this is the best picker I have seen so far.

1. it stops working, without changing a setting in Krita’s settings
2. picking with pen keeps working, when changing a setting in the Tool Options

One more:
Brush tool active → changing a setting within Krita’s settings - closing settings → brush still active → picker stops working → switching to another tool → switching back to brush → picker is working again

It looks good. I think i will get used to it quickly.

[Drawpile]

Okay, yeah, then it’s probably not related to the new setting. If you want to look into it further, you could check if it’s due to the Huion driver by uninstalling that and using OpenTabletDriver instead (check supported tablets and whether you need the Windows Ink plugin): https://opentabletdriver.net/

I think this feature request is also solved with the new color sampler preview options.

Option to disable the two color preview squares sampled on canvas, when using the eyedropper while painting with the brush

While painting, many painters using glazing and build-up techniques are constantly sampling tones from canvas (rather than from the advanced color selector), by continuously clicking the shortcut configured in preferences for having the color picker temporarily for an instant (many of us do configure that shortcut on the pen’s side button). The preview sampled colors appearing constantly (often by a fast instant) ends up being too distracting to paint comfortably. Many painters don’t need to ch…
