Strokes are not painting at cursor position using an "Intuos Pro" in relative positioning mode. The pen cursor moves correctly, like a mouse, but the strokes are painted at absolute pen coordinates, why???

It seems to me that Krita only works with tablets in "absolute mode", which is unusable for most tablet users. (common tablets are usually from small to medium size)

The problem seems very easy to solve since the Mouse draws correctly, at its position. Technically speaking: Coordinates x,y should be taken from mouse events while pressure, angle, etc. are correct (taken from pen)

BTW: Paint Tool SAI is working in relative mode even when the tablet is in absolute mode, which is perfect.

I attached a screen movie for you to understand what I mean.

Thanks!

Hi Jose,

Yes, that is correct, Krita only supports absolute mode. That is, actually, what nearly every drawing tablet user uses. We won't support relative mode any time soon, unless some volunteer steps up and implements it in a maintainable way. Until now, nobody has cared enough to write the code.

Thank you so much, Boudewijn.

I'd like to have a try with Krita debugging and coding, as I did for
pencil2D, but I'm loosing too much time trying to build it ( on windows
with Qt5).
I coded a photoshop like liquify tool for a graphic video game and I can
facilitate you that code, for a smoother effect, without triangulation.

Regards,

Jose (aka Cirus)
