Re: [Inkscape-devel] pressure sensitivity for Pencil tool using powerstroke?

3 Sep 2017

      Hi all.
Yes Im working on brushes, I want to remove the overlaps on same withs
over closed curves on powerstroke using sketetal strokes paper.
Im not sure I can go into the goal :(
About GIMP, Im refering exclusibely to have a tools dialog at right
with unlimited space to do UX work instead the small tools toolbar at
top.
Cheers, Jabier.

It would really be nice to see
fancy brushes into Inkscape like you see in Illustrator, but we
just
don't have the resource or development yet (snip)
Jabier is currently working on brushes (of various types), which was
and should continue to be the focus of this thread.
I recommend we get back to that, and save the software comparison
analogies for another thread.
We should concentrate on helping with the UI tweaks Jabier and others
are requesting, which Inkscape needs to support his new (and old)
features.

Just my 2 cents.

for Inkscape to become a

Does Inkscape really strive to be a vector-brush drawing
program??
Isn't that like saying "vector paint program"?
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.
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".
Referring to a different comment in this thread, I didn't intend
to
"bash" GIMP earlier.  I just dislike the interface, as a personal
opinion.  There's every chance it's an effective interface for a
raster program.  But I don't think it would be effective for
Inkscape.  What's wrong with the Shapes menu, to hold the stroke
profiles or so-called "brushes"?
All best,
brynn

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
Miguel?

suggestion.
You know how you can spray objects and have the path joined
together, right? I'd like to see the option to do that
while
stroking.
