See thing at 0:20. Is this or something similar in Krita as well? If not, could it be added? Seems quite useful, especially if you only have mouse to use. If it's there, how to access it?

only in the freehand path tool, but the stroke in and out stuff isn't(in can be done via distance sensors, out isn't possible atm)

I still recommend a tablet on the basis of 'RSI'.

Yup, but sometimes you have to work e.g. on a train or in a park and tablets aren't easy to tug around. Plus sometimes drivers just don't seem to work. And not all tablets have Linux support (my doesn't), so unless I'll boot into winexcrements, I can't use it.

I think this tool would be great for people that for one or another reason can't use tablet. Also those curves, according to Paintstorm's promo can be applied to other parameters as well, which means also opacity, etc. Really swell and I'd love to see it in Krita.

It was discussed years ago already if there should be a way to change a brush stroke. In practice the feature isn't that useful as could undo and paint it again. If you don't have a tablet you have to tweak every stroke like this which is not practical for the images Krita is made for. So in some sense Krita encourages to get it right the first time

Extending the brush engine would be a lot of work and it's that likely to happen. It might be able to do it with the macro system, but that's a bit cumbersome to use if you just want to change the stroke. I think the easiest way by far would be to fix the tablet support to support your tablet if possible.

Even if you get it right the first time there is one thing that would still strike me as useful:

Curves for brush parameters to vary over the stroke length.

This can not be done while the stylus is still on the tablet, because the full stroke length is not yet known.

But it would be useful for some interesting effects.

Some Examples are shown in the video and one could easily think of others.

- Stroke width modulated by a fixed curve could be used to easily create lots of grass blades or tree leafs wis the same basic shape.

...


In the ui this could just be an additional curve like the pressure curve for each brush parameter. (maybe only visible if you activate "stroke parameters" to avoid ui-clutter)

I don't know enough about the paint engine to say if this would be hard to implement or not, but it would certainly be useful.

Apart from that an interface that allows "Stroke rewriting", could be used for a more advanced stabilizer, since it's much easier to deduce the intention of the artist after the stroke is done.

I'm not arguing that these features should be prioritized. Just that they are not dismissed as useless.

And as i understood it much of the rendering code needs to be rewritten for the performance work anyway so this could be an oportunity to add these interesting features more easily. But again i don't know enough of krita internals to know if this is true.

This is not about rendering code that needs to be rewritten, this would be abput the whole paint system needing to be rewritten.

That said, we do have a wishbug for variable width vector strokes, where features like these wpuld fit in much better, and would make it a subsystem of a far more powerful one.
However, variable width vector strokes will need vectors rewrite, which in turn will have as priority having the text-tool rewritten. And that isn't planned till next year.
