Cheers, Jabier.

If we make up new names for things just to prevent comparisons and
user questions, we sacrifice discover-ability, and also wishlist
items
that make the brush system more versatile and easier to use.

No doubt we get all sorts of questions about raster transformations
from people who are new to a vector editor. This is not a good enough
reason to change common terminology between the programs, it is a
good
opportunity to educate people on the differences between vector and
raster editors.

A vector brush is still a brush, just as a raster brush is still a
brush. The functionality is identical to the user, and so should the
terminology.

Also, when people do compare, we can immediately point out the
advantages of Inkscape vector brushes vs. GIMP brushes - just have
them zoom in. :) They'll get it right away.

-C

If we call them something that more reflects the vector-ness, then
we don't
have that problem.  I'm afraid that people will compare them to
raster
brushes, and they just aren't the same.  They're similar, but so
very
different, at the same time.

In many other areas, Inkscape has created its own terminology...or
used SVG
terminology.  Inkscape calls "nodes" what other programs call
"points", as a
prominent example.  Inkscape calls 'paths" what other programs call
"lines".

I wonder if we could look to SVG (standards) to guide the
terminology...somehow?

All best,
brynn

Does Inkscape really strive to be a vector-brush drawing
program??  Isn't
that like saying "vector paint program"?

Inkscape is a vector drawing program. In previous threads, we
expanded
the term "drawing" to encompass, well pretty much anything. :)
Why limit Inkscape's vector capabilities because it doesn't fit a
particular definition of "drawing"?

I've really seen the term brush used more and more lately, in
reference to
Inkscape, and in what I consider to be an inappropriate
way.  Inkscape can
achieve brush-like effects, with great effort.  But unless there
really is
some plan to actually add true brushes, and develop Inkscape in
that
direction, I think we should discourage using that term.  It
gives a false
impression of Inkscape capabilities, imo.

The term "brush" is used because that's what the effect is.
Inkscape
already has vector brushes in the Caligraphy tool. It's important
to
use terminology that users are familiar with. Saves a lot of
explaining, just to be told "well, why didn't you call them
brushes"
like everyone else? :) I brush (in all graphics programs) refers to
a
shape applied along a path with added transformations. The effect
is
that it acts like a brush, so the term brush is appropriate here as
well as in other drawing/painting/editing applications.

As it's referred to on the Pen and Pencil control bars, I think
Shapes is
better, referring to the profile of the stroke.  Shapes, or maybe
even
"stroke profiles".

Or we could call them "brushes" like everyone else does, and spare
the
user the technical jargon we make up. :)
Our "stroke profiles" are analogous to "brushes" in other programs.
So
when people ask "does Inkscape have brushes?" And we hit them with
"no, but we have stroke profiles." Yea... let's just call them
brushes
like everyone else does, for the same reasons everyone else does.
:)

Referring to a different comment in this thread, I didn't intend
to "bash"
GIMP earlier.

That comment was in regard to the remark "There's something good in
GIMP?" - Don't do this, people. GIMP project are our friends, and
you'll make none here by belittling another projects hard work.

I just dislike the interface, as a personal opinion.

We are not talking about GIMP's whole interface (as if one could
write
it all off as "bad" or something).
Someone is mocking up wireframes based on how GIMP handles brushes.
That's what sparked the GIMP comments... and people keep derailing
the
conversation.
GIMP's entire user interface is not within the scope of this
thread.
Let's see where the wireframes go before denouncing it because it
might look kinda like how GIMP does it.

There's
every chance it's an effective interface for a raster
program.  But I
don't
think it would be effective for Inkscape.

No one is suggesting copying GIMPs whole user interface. :P

What's wrong with the Shapes
menu, to hold the stroke profiles or so-called "brushes"?

"Where are the brushes in Inkscape"
"They are in the 'Shapes Menu'."

Nah, not feeling it, personally. ;) Most everything in Inkscape is
a
"shape". Say "Brush", and people will know what you are talking
about
right away.

No need to reinvent the wheel here from my perspective. We could
call
them "vector brushes" like Krita does. It's important to stick with
terms that are analogous to real life terms that are similar to the
functionality. It makes learning and recall easier, and thus more
intuitive.

I think breaking out the brushes and effects into a dialog of its
own
is really the only way to go. I've not encountered a single
graphics
program out there which handles many (potentially customisable)
brushes that doesn't have it's own side-panel/dock for the brush
pallet. It really MUST happen at some point for Inkscape to
become a
better vector-brush drawing program.

Thanks to all for the hard work on this, esp Jabier!

Hi all.

As far I undertand boolop union result is more for the
caligraphic tool
than for the pencil tool.

Anyway we have a feature that Nate like too much and is not
pressent in
Calligrapic tool is the min/max pressure. This is easy to do
but we
need more space on the toolbox because it not fit into my
monitor size.

Is not the only tool that have this problem and when the
program grow
the problem become bigger. Also because the lack of space we
need to
compress the widgets and make hard to undertand. The cuestion:

¿What about removing this toolbar by a tool dialog in the right
like
for example Gimp, that autoupdate controls between tool
changes?
This give "unlimited" size to expand tools. Also I'm in favor
of a
expander at the end of this dialog for advanced users or not
all day
use features.

Finaly seems easy boolop union with previous strokes in
calligraphic
tool.

Cheers, Jabier.

Hi! I figure I'll just throw myself in here.

It sounds like you are requesting something like the Adobe
illustrator blob brush. Essentially this tool is like
Inkscape's
calligraphy brush with an auto merge feature. Which could in
fact be
a handy feature. In illustrator you can paint with the brush
and the
new shapes merge it with a selection or a layer or maybe even
all.
The same effect can be achieved by using Inkscape's
calligraphy brush
and then merging the shapes. All the blob brush does is make
that
automatic.

The really cool thing you added to the pencil that would also
be cool
on the calligraphy tool is the Max/min size.

Am I correct in my interpretation of what you are asking for

You know how you can spray objects and have the path joined

while
stroking.

Hi all!

This week I do a similar implementation and mark it for

Here are a preview of the new branch running:

Hi All,
I'm Nate, the one who posted in the forums. I started
just

asking if

the feature existed, but was told I should ask for it
as a

feature so

here I am. Hello :)  First I wanted to say I love the
program

and

find the features super useful. The powerstroke is one
of the

coolest

features and I am having a lot of fun playing around
with it. I

have

been an Adobe Illustrator for years but I am already
enjoying
inkscape more. Anyways, the reason I was asking about
pressure
sensitive line work is because it could be a huge time
saver

for

manga art(or any extensive line art) where line work is

incredibly

important. It seems like all of the features actually
exist in
Inkscape, but not together as a tool. The calligraphy
pen works
nicely with pressure and the mass(for precision), but
if the

line

needs to be edited in an meaningful way, they basically
need to

be

redrawn.

The powerstroke feature is awesome, but in its current
state

may

require a lot of manual setting line thicknesses if
there are a

lot

of complicated lines. Being able to control the stroke
width

via

pressure would make it a very smooth process.
Unfortunately it

would

not be as useful without a preview as you draw. Maybe
it could

use

the same preview the calligraphy tool uses? Even if
that isn't

a 100%

representation of the final product, it would guide the
user to
understand how much pressure they are applying.

I asked about an auto simplify feature not only for the
benefit

of

reducing the number of nodes, but also in aiding fast
smoothed

line

work. I see that a line drawn with a pencil has a
smoothing

feature,

maybe that can also be applied to the powerstroke outer
lines

as

well; or maybe the pressure has an adjustable sample
rate?

Additionally, it would be fantastic if there was a way
to

increase or

decrease the relative distance of the powerstroke nodes
from

main

path. In essence it would be like increasing or
decreasing the

width

of the powerstroke. As an example I recorded my screen
using a
variable brush tool in Illustrator. It reads the pen
pressure

and

applies it to the stroke, but also allows that stroke
to be

increases

or decreased.

Screen capture example Video: https://youtu.be/u78JlGD9
Y34

Example of the adobe brush tool simplify/fidelity
options: http

s://yo

utu.be/iIW_oeUcO2E?t=144

That same tool in adobe also has settings to
control/limit the

brush

size and shape. I've been utilizing mass, thinning and
fixation

to

accomplish this effect in Inkscape.

 https://youtu.be/iIW_oeUcO2E?t=97

I think that covers what I was originally asking about
and

more.

Hopefully it was not too much. Thanks so much for all
the hard

work

you have put into the program!  I know this software is
a lot

of work

and new features are no small thing. I am not really a

programmer so

I can't contribute to the effort that way, but if you
have a

need or

desire to include a UX/UI designer I would be happy to
help!

If you got through the whole email, thanks for
listening!

Hi Brynn.

Great and easy to do. I could do if we want. The
problem is

no

realtime
preview, so you need to finish the path to see the
variable

width.

Maybe I can add a preview while drawing but this is
more

complex.

Cheers, Jabier.
________________________________________________

Well I don't use this kind of feature myself.  So I

couldn't say

if

the lack of
live preview would be crippling.  I'll try to get
the

person who

posted the
message to subscribe to the list, so he can give
comments.

How would it work?  Would it add pink nodes where
the

pressure is

greater?  And
then the artist drags them after the path is
finished?  Or

would

the

variable
width be immediately evident when the path is
finished?

And it would only work with graphics tablets?

One benefit for such a tool (it seems to me) would
be that

the

number

of nodes
probably would not build up so fast, as it does
with

Calligraphy.

Thanks, Jabier.  I'll try to get this guy to
subscribe so

he can

discuss
directly.

All best,,
