GSoC - transformation anchors - before apply
by Zhenfeng Zhao 26 Mar '10

26 Mar '10

Hello, I am interested in working on the "transformation-anchors" project in GSOC this year. I am a graduate student in Computer Science in Canada. I knew Inkscape would win GSOC projects this year, as usual. :-) Congrats. I hope it is not too late to say Hi here. Inkscape is one of my favorite open source software. I also have strong interests and work experiences in image processing, image editors. I have developed a vector-based graphics editor from scratch before. That graphics editor uses customized XML formats, have OOP architecture design to deal with all shapes/primitives with object classes, and allow SVG and DXF (Solidworks drawing file) import and export. Therefore, it seems Inkscape GSoC projects are most interesting and relevant to me. The project, transformation-anchors, seems interesting and doable to me. Wiki docs are very helpful. It is impressive that GUI mock-up has already been posted several months before the Gsoc actually starts. I will read and plan in further detail. I have similar work before, to have the default rotation center to be the geometric center of all shapes. Anchor coordinates are a part of the object (drawing) attributes. It can be adjusted, so that geometrical transformations, rotation, translation, scaling, and shearing, can be performed with the updated center. In this project, there will be some GUI modification, e.g. enable and disable buttons, display coordinates and values, take XY input from users, and allow undo and redo. Maybe some nice intuitive and simple designs will help on these. There may be some refactoring to do, but I am not sure. In this stage, I hope to understand more for this project. Please kindly share comments. I will draft a full proposal in about 10 days. Technically, this project seems doable to me. Besides that I am good in C++, which may be a basic requirement, I have done some work using the following. XML: I have used it for many projects, using C++, Python, C# and Java. Libraries used: .NET, DOM, JDOM, Minidom. SVG: I have written a SVG viewer before. GTK+: I have experience with it. It is the most complex GUI widgets that I have used. SVN: I used it at work before. Regards, Zhenfeng.

What about to use translations.launchpad.net? May be useful...
by Aurélio A. Heckert 26 Mar '10

26 Mar '10

Hi all, What you think about to use the web based launchpad's l10n system? https://translations.launchpad.net/inkscape I think that will be really more ease to get collaboration from our users. Gwibber is using this system. Cool? Aurium -- Aurélio A.

KML import status
by Will Holcomb 25 Mar '10

25 Mar '10

I was looking through the GSoC possiblities and I'm particularly interested in the KML import project: https://blueprints.launchpad.net/inkscape/+spec/kml-svg-translation I see reference to a project proposal being developed, however the link is now dead: http://socghop.appspot.com/student_proposal/show/google/gsoc2009/piotrekk/t… Given that project is still open, I assume that the proposal didn't go forward for some reason. I was wondering if anyone had further information as to why. I've been thinking quite a bit about the hyperlocal movement and I've been trying to come up with a reasonable way for users to add more complex structures to maps than what is available in browser-based drawing programs. It seems like this is a strong possibility, is there still interest in developing this feature? -Will

I assume that it would be better than SVN, which seems to be used previously. (?) Regards, Zhenfeng.

experimental LPE
by Uwe Schöler - OSS-Marketplace.com 24 Mar '10

24 Mar '10

Hi, in the last couple of testbuilds for windows are experimental LPE's enabled. On Ubuntu there are only a few effects available, but on windows builds are a lot of effects. And many of them let inkscape crash. Why do we have these unstable effects still enabled? Sincerely UweSch -- Mit freundlichem Gruß, Uwe Schöler

Inkscape-Aqua for Snow Leopard
by Stuart Edwards 24 Mar '10

24 Mar '10

There is now a pre-packaged version of Inkscape running native on my MacPro under OS X 10.6.2. That's the good news. The bad news is that there's some more work needed to make it useable. On start up I get the following console messages: 3/23/10 8:51:51 AM defaults[41485] The domain/default pair of (kCFPreferencesAnyApplication, AppleAquaColorVariant) does not exist 3/23/10 8:51:51 AM defaults[41487] The domain/default pair of (kCFPreferencesAnyApplication, AppleHighlightColor) does not exist 3/23/10 8:51:51 AM defaults[41496] The domain/default pair of (.GlobalPreferences, AppleCollationOrder) does not exist 3/23/10 8:51:51 AM [0x0-0x606606].org.inkscape.Inkscape[41457] Warning: AppleCollationOrder setting not found, using AppleLocale. 3/23/10 8:51:51 AM [0x0-0x606606].org.inkscape.Inkscape[41457] Setting Language: .UTF-8 3/23/10 8:51:51 AM [0x0-0x606606].org.inkscape.Inkscape[41457] cp: /Users/stu/inkscape_port/inkscape-0.47/packaging/macosx/stInkscape-aqua.app/Contents/Resources/etc/pango/pangox.aliases: No such file or directory 3/23/10 8:51:51 AM [0x0-0x606606].org.inkscape.Inkscape[41457] (process:41460): Gtk-WARNING **: Locale not supported by C library. 3/23/10 8:51:51 AM [0x0-0x606606].org.inkscape.Inkscape[41457] Using the fallback 'C' locale. 3/23/10 8:51:54 AM [0x0-0x606606].org.inkscape.Inkscape[41457] (inkscape-bin:41460): GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed 3/23/10 8:51:58 AM [0x0-0x606606].org.inkscape.Inkscape[41457] (inkscape-bin:41460): GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed 3/23/10 8:51:58 AM [0x0-0x606606].org.inkscape.Inkscape[41457] (inkscape-bin:41460): Gtk-WARNING **: Could not find the icon 'object-visible'.

Based on a quick 'tour', the basic functionality of the drawing tools etc seems to be in place. Of course, the two problems discussed in previous threads are still with us - the lack of radio buttons and the non appearance of aqua drop down menu items that have secondary menus associated with them. Another fairly critical item - saving the current document to file - causes a crash at the point where the 'save' button on the file dialog box is activated. This creates a series of console messages: 3/23/10 8:54:15 AM [0x0-0x606606].org.inkscape.Inkscape[41457] (inkscape-bin:41460): Gtk-WARNING **: Unable to find default local directory monitor type 3/23/10 8:54:35 AM [0x0-0x606606].org.inkscape.Inkscape[41457] (inkscape-bin:41460): Gtk-WARNING **: Unable to find default local directory monitor type 3/23/10 8:54:35 AM [0x0-0x606606].org.inkscape.Inkscape[41457] Emergency save activated! 3/23/10 8:54:35 AM [0x0-0x606606].org.inkscape.Inkscape[41457] Emergency save completed.

Hello everybody & GSoC Open Asset Import Library
by Alexander Gessler 24 Mar '10

24 Mar '10

Hello inkscape-devel! basing on the suggested ideas of last year (http://wiki.inkscape.org/wiki/index.php/Google_Summer_Of_Code), I'd really love to tackle one of the suggestions, actually the 3d file import stuff. Open Asset Import Library (http://sf.net/projects/assimp) is a sort of generic importer library for 3d models, it supports two douzens of file formats from various 3d apps, frameworks, games, such as 3ds, obj, Collada, x, md5, ... Project exists since 2008, is hacked on by a team of 5-6 people. I'm currently the main committer, always trying to keep things together. Basing on the '3D Polyhedron' extension, the idea would be to integrate Assimp as model importer to get access to a wide range of formats. After importing, display a sort of real-time preview (in a separate window with OpenGL, maybe?) so the user can choose his preferred view point, lighting, whatever. When he's done, the model would be projected onto the drawing plane, converted to inkscape polygons and grouped together. Fancy stuff such as flat-shading and other things would be quite easy to accomplish. Also, Assimps development will surely continue, so format support might be improved in future (Diederik van Lierop pointed out that CAD file formats are mostly missing, also there's no support for Blenders native format yet). A few words to myself: I'm currently 18. Attending the german equivalent of highschool in year 12 of 13. A bit computer-addicted (just a little bit, you know :-) Worked with a few software technologies, in terms of programming languages mostly C, Python, C++. Also, I do like anything related to computer graphics. No development experience with Inkscape' source code yet (biggest achievement so far: it compiles), but I like the app and use it regularly and would like to contribute in future. GSoC seems a great opportunity. Please tell what you think. Regards Alexander Gessler

Saving preferences
by Martin Sucha 23 Mar '10

23 Mar '10

Hello all, I today closed a group of 6 Inkscape 0.47 windows and ended up with a corrupted preferences file. Is it possible that multiple Inkscape instances were writing to the same file at the same time? Has anyone encountered this before? Thanks. Regards, Martin Sucha

(I'd prefer to keep > it on inkscape-devel and not fork into several private threads). ok, we're back on the devel list now - sdk10.4 was an optional install that I didn't think I'd need. Now I have it. Probably a(nother) dumb question - but how (and when) do I switch to gcc 4.0 ? If I use the current script with sdk 10.4, will the result be useable on 10.6? I'll work on a bug report once I get to the end of this effort and can tell better what were true bugs and what was just my ignorance ; ) thx Stu
