Eraser
by Jabiertxo Arraiza Cenoz
Hello.
I have realized that an extension inkscape, by means of filters and
clones
makes some other deleted objects in overlapping parts, something
also cut live.
The problem is quite complicated and the resulting svg uses a
filter that erodes quality minimally deleted edges, which I think would
be invaluable in print because you have to
maximum zoom to see the difference of pixelization.
Researching upcoming SVG specification have seen that the primitive
blend filter-I-will have to incorporate a new method that is
draft.
I understand it's a little early to incorporate it into inkscape, but it
occurred to me that if you could add a new element to inkscape namespace
for the element that contains all Scrap right of the lower elements of
the group.
More could be done adelate this namespace be reflected in any svg
renderer thanks to the new way of blend filter primitive.
Now I'm starting with B-Spline extension but I think this is a good
thing for inkscape, and they can see how it works if you install the
extension in the latest stable version, is not urgent since no
alternative but can be interesting look.
The extension is set in inkscape forums with a link to the website of my
company and a donation button if any millionaire out there .

Yo he realizado una extensión en inkscape que, por medio de filtros y
clones
hace que unos objetos borren a otros en las partes coincidentes, algo
asi como un recorte en vivo.
El problema es que complica bastante el svg resultante y hace uso de un
filtro que hace perder minimamente la calidad de los bordes borrados,
cosa que considero que sería inapreciable en impresion ya que hay que
hacer un zoom máximo para apreciar la diferencia de pixelización.
Investigando la próxima especificación de SVG he visto que la primitiva
de filtro mezclar -creo- va ha incorporar un nuevo metodo que se trata
de borrador.
Entiendo que es un poco pronto para incorporarlo a inkscape, pero se me
ha ocurrido que si se podria añadir un nuevo elemento al espacio de
nombres de inkscape para que el elemento que lo contenga haga de
borrrador de todos los elementos inferiores de su grupo.
Más adelate se podria hacer que este namespace se reflejase en cualquier
renderizador de svg gracias a el nuevo modo de la primitiva de filtro
mezclar.
Yo ahora mismo estoy empezando con la extensión B-Spline pero considero
que esta es una buena cosa para inkscape, y ademas pueden verla en
funcionamiento si se instalan la extension en la última versión estable,
no es algo urgente ya que hay alternativa pero puede ser interesante
mirarlo.
La extensión está puesta en los foros de inkscape con un enlace a la web
de mi empresa y un boton de donación por si hay algún millonario por
ahi.

Re: [Inkscape-devel] B-Spline
by Jabiertxo Arraiza Cenoz
Good morning.
I am very glad that people are getting involved in the project. I thank
especially Arshdeep Singh for offering with such enthusiasm, I look
forward to working with him and learn.
I am also happy news for the project provided by Johan Engelen lib2geom
of the project, which seems key to the achievement of the B-Splines in
Inkscape.
For my part I contribute my part of the way and start coding before I
point out what I think we need to get.
The BSplines give the artist total control to make layouts without using
handlers, giving a speed and accuracy, I think, unique in the world of
drawing.
This feature is primarily patent while you draw each stroke, implement
this feature at the end of the path has no make much sense.
I therefore propose branch-if so-called the project into two consecutive
parts:
The first is a part facilitator also has benefits spiro tool. They are
getting while drawing a spiro curve, the mark of the "road" is already
the final route, without going into consideration to show both paths
and / or buttons to switch.
The second would be to implement a curve BSpline like a Spiro.
In both modes "spiro" and "BSPLINE" would be important to assign a key
to draw the next point is a corner point.
Do you think well this way?
-------------------------------------------------------------
Buenos días.
Estoy muy contento de la gente que se está involucrando en el proyecto.
Le doy gracias especialmente a Arshdeep Singh por ofrecerse con ese
entusiasmo, estoy deseoso de poder trabajar junto a el y aprender.
Me alegra también la noticia a favor del proyecto facilitada por Johan
Engelen de el proyecto lib2geom, que parece clave para la consecución de
las B-Splines en Inkscape.
Yo por mi parte aporto mi parte del camino y antes de empezar a
codificar quiero puntualizar lo que pienso que tenemos que conseguir.
Las BSplines dan al dibujante total control al realizar trazados sin
necesidad de usar manejadores, dando una velocidad y precisión únicas
-creo- en el mundo del dibujo.
Esta característica es patente principalmente mientras se va dibujando
cada trazo, implementar dicha característica al final de realizar el
trazado no tiene mucho sentido.
Por ello propongo bifurcar -si se llama así- el proyecto en dos partes
consecutivas:
La primera es una parte facilitadora que además tiene beneficios para la
herramienta spiro. Se trata de conseguir mientras se dibuja una curva
spiro, que la marca del "camino" sea ya el trazado final, sin entrar en
consideración de mostrar ambos trayectos y / o botones para alternar.
La segunda seria implementar la curva BSpline como una Spiro.
En ambos modos "spiro" y "bspline" seria importante asignar una tecla
para que el siguiente punto a dibujar sea un punto de esquina.
¿Os parece bien este camino?

I am a computer graphics enthusiast who loves mathematics. The idea of
implementing B-Splines seems really cool. I am proficient in C/C++.
And I am doing a course in college that covers the basics of Beizer
Curves and B-Splines. Can I be of any help ?

Thanks for the response.

It doesn't seem to be giving me an color managed screen proof though. If
I fill a square with a hexadecimal value in Inkscape and fill a square
with the same value in Gimp, on screen they look like two different colors.

This is unfortunate, but as long as I am primarily working in sRGB this
is still usable for created screen/web graphics.
Thanks again.

Color Management Doesn’t Seem to Work
by Jason Simanek
Hi,
I'm trying to nail down a color managed workflow for my design work
(print and web). I am running Inkscape Trunk on Ubuntu 12.04. I can't
seem to get Inkscape to output color managed colors.
For a test I export my Inkscape artwork as a PNG and open the resulting
PNG in Firefox (with full color management turned on) as well as Gimp
(with color management turned on).
My laptop display has been calibrated with a colorimeter via
colord/Argyle. I have assigned this display color profile in both Gimp
and Inkscape preferences.
The colors in my graphic should match in all three applications, but
Inkscape is obviously showing over-saturated colors while Gimp and
Firefox match exactly.
Am I doing something wrong? Is color management in Inkscape not really
working correctly yet?
Any help is much appreciated.

Shared library
by Alex Valavanis
Hi All,
I'm not an expert on this kind of thing, but is there a reason why we
don't distribute libinkscape as a shared library? At the moment,
Inkscape and Inkview share a huge amount of code and they are both
pretty big executables. Presumably, we'd save a lot of installation
space with a shared lib.

Re: [Inkscape-devel] B-Spline
by Jabiertxo Arraiza Cenoz
According council go Gronde Jasper I decided not to do before an
extension in Python. I created a branch in Launchpad called B-Spline.
As I want to make it work with the tool Beizer I have a problem. This is
the result I want to see while drawing tool like calligraphic strokes.
Subtraction accurately understand this if, for example, stroke is the
width or has a color similar to background. From what I see important
that the line where the stroke will go, once completed, should continue
as a curve or BSPLINE spiro and not currently a curve Beizer.
For as designed the efect that are updated live to close the path not
know if this is possible or not. Does anyone know?

Re: [Inkscape-devel] B-Spline

Traductor
inkscape create a path effect
In the attached document on the B-splines, especially in point 4, I read
the way a cubic Beizer curve, generate another curve to follow another
path to simulate a curve B-Spline.
At this point I find doubts.
I understand that the ideal is that the system works as curbas Spyro.
The Spyro curbas are really a "LIVE PATH EFFECT".
My ask is:
I have doubts if start is better here or a different starting point and
go directly to the "live path effects"
My current point is: develop it as an extension in Python that from a
path, create another with the path I should follow BSPLINE for points
and handles used in the original path.
Moreover Barendrecht Pieter offered me another way with groups but do
not understand. Thanks Peter.
Thank you very much in advance for their cooperation.

Future releases
by Josh Andler
Hey All,
I'd like to proposed that after we get 0.49 out the door, we have
regular planned releases. No more "always open" trunk development. But
leverage merge windows instead... which also means needing to land
"more complete" features in trunk than we've historically allowed. I'd
love to see us have 6 month cycles to get features and fixes out to
users sooner. It's awesome to have flashy new stuff for every release,
but it's just not necessary.
What are people's thoughts on this tried and true strategy many other
projects use? Can we at least give it a shot?
Cheers,
Josh
