Color-interpolation properties
by Jasper van de Gronde 12 Jan '09

12 Jan '09

I found out at least one source of differences in rendering of filters between Inkscape and Batik/W3C test suite, and that's the color-interpolation-filters property. This property determines the color space used for filter operations (color-interpolation does the same for gradients and normal compositing), and Inkscape doesn't support it at the moment. The problem is that by default color-interpolation is set to sRGB and color-interpolation-filters to linearRGB (sRGB before the gamma adjustment)... There was probably some rationale for this, but it's a pretty big nuisance, as it means that we'll probably have to convert to and from linearRGB for each application of filtering (as the conversion is very much non-linear). Also, this means that pretty much any file that uses filters should actually be rendered differently from how it is rendered now (and often quite visibly different). So it might be a good idea to do something about this ASAP, to minimize the impact. So, now my question is: What to do about this? There are a number of possibilities. First of all, Inkscape could start setting the color-interpolation-filters property to use sRGB. This would probably be a very quick "fix" and at least ensure that any new files created with Inkscape will render the same in other (compliant) viewers. Obviously this wouldn't resolve problems with current files. The main other possibility is to add support for color-interpolation-filters. Obviously this is the right thing to do in the long run, but it's also tricky to do it right. Quality (and probably performance) wise it would likely be best to allow the conversion to be part of the filter, as for example gaussian blur already uses increased precision internally and could apply the conversions with little loss in quality. However, it would obviously be much easier to simply write conversion functions and call them before and after applying any filters. And even if support for color-interpolation-filters is added, it might still make sense to set it to sRGB (or set color-interpolation to linearRGB), as letting the settings be different results in non-intuitive behaviour like having normal compositing behaving differently from the equivalent feBlend and feComposite modes.

Re: [Inkscape-devel] [Inkscape-user] Clear Open recent?
by Felipe Sanches 11 Jan '09

11 Jan '09

I have added a button to the Interface page in the Inkscape preferences dialog that will remove all items of the "File -> Open Recent" menu. The code was commited in the svn revision number 20503 and the feature will probably be in the next stable release, I hope. Could anybory review my code, please? It is the first time I deal with GtkRecentManager. Could you please review it, Bulia?

extension namespace
by Thomas Holder 11 Jan '09

11 Jan '09

Hi there, is it possible to make the new namespace for inx files optional? I see no real benefit for the namespace, but it is a real drawback that all previous custom extensions will become invalid (until you add the namespace to the inx files). When we release 0.47 lots of users will be confused and will report bugs for this I guess. Thomas

3D importing
by Alexandre Prokoudine 11 Jan '09

11 Jan '09

Hi, Since recently we have an OBJ importer in form of an extension. IIRC there was a debate how this extension should be implemented better (real importer vs. extension). So, I've just stumbled upon http://assimp.sourceforge.net/ -- Open Asset Import Library, which is designed to help importing various 3D scene files into applications. It covers not just Obj, but also 15 more file formats, including 3D Max and the like. Could be a good GSoC2009 project for somebody, especially if importing would come with live preview :) Alexandre

Tr : Inkscape 0.46 Devel Dependencies
by Ivan Louette 11 Jan '09

11 Jan '09

That's allright now ! I did a mistake in the package source address... Inkscape 0.46 Devel runs now on my Kubuntu ! I am happy to be able to continue filters development. That will be a little bit slower because at the moment I am very busy to write a book. But these days I also tried the compatibilities between Inkscape and Fontforge and I am sure svg filters will add something new in my font creation ideas... Thanks to everybody here for the hard work ! Very friendly ivan ________________________________ ----- Message transféré ---- De : Ivan Louette <ivan_louette@...48...> À : Inkscape-devel(a)lists.sourceforge.net Envoyé le : Dimanche, 11 Janvier 2009, 17h29mn 41s Objet : Inkscape 0.46 Devel Dependencies Hello !

Calling init_gtkmm_internals()
by Jasper van de Gronde 10 Jan '09

10 Jan '09

I found that to make rendering of feImage filters work correctly I have to call Gtk::Main::init_gtkmm_internals() before trying to use Gdk::Pixbuf. If this is not done it complains about not being able to wrap GdkPixbuf. With this change it suddenly seems to work just fine. However, I have no idea where it should be put. At the moment I put it in nr-filter-image.cpp (because that was were the problem was occurring), but it would probably be better to do it while starting Inkscape. However, it should also be called for Inkview. And perhaps it should be called after/before some other things? So, if someone who is a bit more familiar with GtkMM (and Inkscape's initialization) could have a look at this, that would be great. This very simply change will make feImage's with references to files work automagically :) (There are probably still a few caveats, but still.)

JavaFX 1.0 support
by Adam Giemza 09 Jan '09

09 Jan '09

Hello all, I know from this blog http://silveiraneto.net/2008/11/21/inkscape-and-javafx-working-together/ that there is JavaFX support build in the latest (0.46) build. BUT the problem is, that this support is for pre-1.0 releases of JavaFX. Silveira (the guy from the blog) postet in his todo list, that the 1.0 support will come on Dec. 2nd. But there is still nothing in this direction, right? I posted a comment on his blog, asking for the progres without any reaction. Maybe somebody here can take up this topic. Would be very much appreciated! Cheers, deradam (Also posted in the InkscapeForum -> http://www.inkscapeforum.com/viewtopic.php?f=20&t=2091)

Hello inkscape-devel, My name is Dmitry, I'm a student from Russia. I'm interested in developing your project and participating in next Summer of Code (2009). I want to know about ideas, which I can take part in. And I'm going to make this work to be my master thesis at University. -- Best regards, Dmitry mailto:Dmitry.Jurasov@...400...

Inkscape and good causes
by Josh Andler 09 Jan '09

09 Jan '09

Hey all, I decided to pass this along as it is in the same basic spirit of open source with the attitude of doing something for a cause greater than one's self (our global community). Recently there was a contest held on DeviantART to promote breast cancer awareness and early prevention that was sponsored by DeviantART, MGM (yes, the studio), and the Susan G. Komen for the Cure Foundation. With over 1,400 submissions spanning all kinds of art forms imaginable, the Grand Prize Winner chosen was by one of our Inkscapers on DA (and yes she used Inkscape for this), Loraine A. Baird, aka QuicheLoraine. The competition results are here (which contains a link to her winning entry, but also shows a few runners up for reference): http://news.deviantart.com/article/66804/ And her gallery which contains quite a bit of excellent work done in inkscape can be seen here: http://quicheloraine.deviantart.com/gallery/ Congratulations to her, and if you have a DA account it would be nice to drop by and leave her a comment. Cheers, Josh
