Talks for SVGOpen (the graphical web).
by Tavmjong Bah 11 Sep '12

Hi, I've posted drafts of my talks for SVG Open 2012 (now known as "The Graphical Web") to my website. Comments welcomed. I give both talks Tuesday morning in Zurich. The talks use JessyInk and require you to hit Page Down twice to get to the first slide. Firefox messes up some figures while Chrome doesn't do indenting text spaces well.

Eraser

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 . http://www.inkscapeforum.com/viewtopic.php?f=11&t=12517 ------------------------------------------------------------------------------------ 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. http://www.inkscapeforum.com/viewtopic.php?f=11&t=12517

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?

Color Management Doesn’t Seem to Work
by Jason Simanek 09 Sep '12

09 Sep '12

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. Jason Simanek

Shared library
by Alex Valavanis 07 Sep '12

07 Sep '12

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. AV

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?

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 05 Sep '12

05 Sep '12

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

Please Update Release Notes!
by Tavmjong Bah 04 Sep '12

04 Sep '12

Hi, I will be giving an Inkscape status talk at the "Graphical Web" conference (formerly "SVG Open") in two weeks. It would be very useful if the release notes for 0.49 were up-to-date. I know there are some important things missing like the recent updates to the Text toolbar and the removal of the Gradient dialog. Can all developers who have made significant changes please up date the release notes if they haven't done so already? Thanks, Tsv

SVG 2 and Inkscape
by Tavmjong Bah 03 Sep '12

03 Sep '12

Hi all, As has been noted by Alexandre, the first public draft of SVG 2.0 has been released: http://www.w3.org/TR/2012/WD-SVG2-20120828/ While this is a very early draft and will be unstable for some time, I don't think it is too early to make plans on how Inkscape will handle incorporating new SVG feature. SVG 2.0 will bring many things that will benefit Inkscape. Here are just a few: Mesh Gradients New blend modes New ways to specify color (CSS3 Color) Named colors Markers inheriting stroke color Hash lines Variable stroke placement (inside/outside path) Fill over stroke 3D transforms Before I make a proposal, I will review the status of the SVG in general. As many of you know, SVG as a standard almost died when Adobe bought Flash. (Adobe was the main driver behind SVG at the beginning.) The SVG Working Group (WG), which once had more members than the CSS WG, shrunk to just a handful of active participants. With SVG now being a core component of HTML5 and with SVG being added to IE 9 and the decision by Adobe to stop development work on Flash, interest in SVG has grown. New members have joined the WG over the past year. (The group is still smaller than the CSS WG which limits the speed that the SVG 2 specification is developed as well as what can be added.) In addition to renewed interest in SVG proper, there is interest in adapting many SVG features for more general use on the Web. Many parts of the SVG specification are being ripped out and made into stand-alone specifications shared with the CSS WG. These include Transforms, Blend modes, Filters, and Colors. These sections are maturing fast and experiencing rapid adoption by browser vendors. You can already use HSL colors (from CSS3 Colors) inside SVG in current versions of all major browsers. Transformations should be usable soon. In summary, SVG is moving forward and doing so rather quickly. How should Inkscape handle new features? First of all, as Josh has stated, we don't want a repeat of the flowtext fiasco where Inkscape implemented a feature that ended up not being added to the SVG specification. We should only enable stable features in our official releases. One indication of stability is the implementation of a new feature by one or more browser vendors without using a vendor specific prefix. HSL color is one example of this. We should encourage new features in unstable releases. It is important to the SVG specification development that there are working examples, even if only partially implemented, as it demonstrates a user desire for the feature and it gives the WG a chance to test and experiment with it. Second we should be backwards compatible with SVG 1.1 when feasible. By backwards compatible, I mean being able to read and write SVG 1.1 files. Some things are relatively simple to handle. HSL colors can be easily converted to RGB colors. Others like mesh gradients may require using a PNG. What I propose, is that as new features become stable, we modify the internal Inkscape code to use them while at the same time adding an option to export to SVG 1.1. In many cases, this will have the side benefit of simplifying our code. For example, matching marker color to stroke color now requires some rather complex code to create new copies of a marker for each different colored path as well as monitor changes to stroke and fill color. What do others think? Tav

Hello to all. I know some Python and I am able to use inkscape develop curve B-Spline. The Spyro curbas are fine for artistic themes but the B-Spline give greater accuracy with less work. Not quite where to begin. I have the mathematical formula for creating splines that I got Internet, I have always worked with programs in script and not much to compile C or anything Can you help me with the first / ... steps? Greetings from Pamplona. Sorry for my English.

Google Summer of Code 2012 Results
by Josh Andler 29 Aug '12

29 Aug '12

Hello Inkscapers! The Google Summer of Code 2012 program is now officially over. We’ve managed to have 3 out of 5 projects successfully completed by our awesome students. * Jan Pulmann created Python bindings for lib2Geom, the computational geometry library we use in Inkscape. * Samuel Chase made a lot of internal improvements to handling guides and to the coordinates system, making it easier to switch away from Cartesian system. * Veronika Irvine created a new tool for on-canvas tessellation. The code for 2geom library was written in the main development branch and hence is immediately available to all 3rd party developers. The changes to Inkscape have to be finalized before they can enter the main source code repository. Currently we don’t expect both of the new Inkscape features to be used in upcoming v0.49. We are sorry that 2 students didn’t make it, and we are going to take steps to avoid this kind of failure in the future, should we be accepted for the next runs of the program. Cheers, Josh (on behalf of the Inkscape team)

Hi, SVG Working Group release the first public draft of SVG 2.0. http://www.w3.org/TR/2012/WD-SVG2-20120828/ Among other important things it has: 1) Reference to the new "Blending and compositing" spec released earlier this month: https://dvcs.w3.org/hg/FXTF/rawfile/tip/compositing/index.html Among the outcomes: more useful blending modes. 2) LAB color, uncalibrated device color, with raw CMYK and n-channel data. There are people around who would kill for these features in Inkscape. Do we have any policy regarding adoptions of new SVG stuff? Alexandre Prokoudine http://libregraphicsworld.org

GTK+-3.0 acting strangely
by Arshdeep Singh 28 Aug '12

28 Aug '12

Hi everyone, I recently coded my first GTK+ app. I had first precisely followed the instructions shown on the "Compiling GTK+" page. The app successfully compiled and ran too. Then I had to turn off my computer as i had an errand to run. The problem now is that, when I restarted the laptop, I had to re-install the GTK+ library although it was present in the /opt/gtk folder. Again I was successfully able to compile and run the app. However when i closed the interval pkg-config no lobger recognised gtk+-3.0 as an installed library ! It seems somehow the changes I make when I install the library do not make it after I close the terminal. What to do, I cannot install gtk everytime I need to run my code ! -- demicoder

0.49 Release Plan Discussion
by Josh Andler 19 Aug '12

19 Aug '12

Hey All, It seems like it would be jumping the gun to put forth a proposed release plan without getting input from everyone on what should and should not be pursued during this cycle. After some feedback it should be a bit easier to put forth a somewhat realistic timeframe. Again, the goal is still to have a release before the end of the year. (Note: 0.48.4 is going to be cut hopefully in the next week or so) First, I want to address, what major features and issues are still left that people want include and will be able to wrap up in the near future? We still have some outstanding bugs with the new renderer which should really be addressed when possible. I know I will be going through the tracker soon to look for our blockers and must-fixes... others are welcome to do this as well. Our "start" time is still pretty unfriendly... valgrind just screams that it's fontconfig taking up the biggest chunk of this. I have no clue though if anyone is interested in taking this on. Also, it's time we get the skeletal pieces in place is the release notes. If you don't have time to write the full text, please write a placeholder Todo. Anyone is welcome to do this, if you are the author of a new feature or notable change or bugfix, traditionally you are the one to write this (as you're usually the most familiar with the feature). I don't believe we should include compatibility to compile against GTK3 as it will be viewed as a supported feature. So, where do we stand. I would really like to get a proposed release plan out in the next week if possible. Any suggestions for a theme for this release's About screen contest? Cheers, Josh

Augh, can someone do something about those "WARNING **: Inkscape currently only supports color-interpolation-filters = sRGB" messages? They're clogging up my console while I'm trying to get other bug messages. :( (but all my text tool problems are gone, yay!) Anyway, sorry for the delay. > This is weird, because it is exactly these two things that I fixed! > Can you send me an example file? Still Inkscape 0.48+devel r11297. There are two files attached: - The New doc file is the first file that crashed when I was testing Powerstroke. In fact, even now, it crashes Right when I open it. :P Which is rather fortunate because I wasn't able to get a second file that crashed once to crash again, nor the Tests file. - The Tests file is my more systematic attempt to reproduce the error messages. I basically started with the same-ish shape for different algorithms and cusps and attempted to torture the lines until I got a proper error message. In particular, I've marked one shape where it was quite easy to reproduce this error message: WARNING **: Exception during LPE [Unstable!] Power stroke execution. lib2geom exception: Invariants violation (./2geom/piecewise.h:144) Just select with the F2 tool, and drag the diamond back and forth between where the two lines point at. The error message should pop up. I was able to reproduce that error in several other lines but not as systematically. It seems to affect mostly the Linear and Spiro algorithms, though it may affect other line types too. It usually happens when editing the powerstroke width. No matter what I did though, I wasn't able to reproduce a crash in this session (and not for lack of trying).
