question about brush strokes

[donbartolo]

Hello to all !

Is it possible with Tv-Paint to choose how a brush stroke begins and ends ? With others words, is there a kind of stroke-in and stroke-out parameter ?

Exemple:

I want to achieve a brushstroke that gets bigger according to penn-pressure and always begins and ends very thin.




Thx forward

I can't quite understand your question.
if you set the size to be controlled by pen pressure, then all you have to do is begin and end a stroke lightly - this will give you the tapered ends.
In order to make stronger sure that the ends get tapered, curve your pressure connection profile like this:

P.S - if you fail to get thin ends, check your tablet preferences and set the pressure sensitivity to firmer.

Thx for replying malcooning!

I never played with "profile: size". Your suggestion seems to be the solution! i'll give it a try and come back.

( To make it clearer :
see a brush fade in and fade-out as a filter on the brush stroke. It's not directely linked to the penn-pressure. it just makes the beginning or end of your stroke sharper.
You can compare it to a fade filter applied on a sound file )

Use the Fade connection with the size, and Edit it like this. Don't hesitate to change the Fade seetings into "Options" (when Right clicking on the connections)

O hooo! coowl.

Thx also, Elodie!! :p

yeap, fade works pretty well with vector-drawing tools, but not "smart" enough with freehand tool.
in fact, it needs to know the start and end points before applying, to perform the desired % length
of ease-in and % length of ease-out, with freehand (raster) tool, it draws the begining of the stroke
without knowing how long the stroke will be, so the fade occures relatively to the brush settings
(size/stepping), and not the stroke length. (see pict.)

Also, Fade doesn't serve the purpose here because Pen Pressure doesn't get any manifestation here.
If such effect is much needed maybe a vector program is more suitable for the task.
Here, in bitmap, as in bitmap, you rely on your hands

in addition to the Size/Fade connection, pressure could size up/down the stoke's thickness as well, you just have to make an animated custombrush (varying its size) and connect the animation on Pressure.
(just to mention this workaround).

good point Zig.

"Here, in bitmap, as in bitmap, you rely on your hands "

Vector is not Evil you know. Nowadays the use of well-developed vector tools can feel - in some cases- as natural as using a bitmap-brush. Using one doens't exclude the other: they are complementary and can work very well together.

There is not that much difference between bitmap and vector : both are digital and both are made on your computer with your own hands. (In the eighties a part of the artists have been telling the same kind of talk about 'computers'. And if it really was so, there would never have been Tv-Paint... )

But i know you're just teasing. I greately appreciate your feedback.

I'll try to make a brush that suites my needs with tv-paint !

you induce, where you should be deducing. I didn't say anything bad about vector. or, in fact, I didn't say anything at all about vectors - I said about bitmap.
I know all the pros and cons of vectors and bitmaps, and the reason I'm here using bitmap is because it suits my way of working.
bitmap allows me the kind of freedom that is more closely matching my way of working with real matter.
And actually, if TVP was able to do exactly what it does today, but in vectors, then all the better. (bar the enormous file sizes...)
Or, in other words, I wouldn't even care what technology it uses if it'd do it well.

Humm... i think i hurted your artistic feelings. Surely my bad sense of humour. Sorry for that.

The only thing i say is:
You can achieve with vector also very natural work relying on your own hands in a COMPLEMENTARY way to bitmap.
i never said it has to replace bitmap in TVpaint. That should be a great mistake! But... I am just saying it could co-exist with bitmap in TV Paint.

We were talking about that 'fade' problem on a stroke, you remember ? In this case a vector brush would be a nice alternative. That's all.
(Like 'Manga Studio' does: you can choose between both in a same project: bitmap and vector layers )

Still friends, i hope?
