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?

Thanks for the response. On 09/09/2012 10:43 AM, S.Kemter wrote: > The CM functionality in Inkscape means screen proof and adding the > profile to the svg, as the standard supports this. 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. > For export to png Inkscape uses cairo and that doesnt support this > feature. This is unfortunate, but as long as I am primarily working in sRGB this is still usable for created screen/web graphics. Thanks again. Jason Simanek

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

Thanks Pieter. a simple cuestion. My goal is a button near spyro button for made the bsplines. Is posibol to made entire proyect in phyton or need to learn C? Sorry burt im a beginer programer. Thanks very much for the quick response.
