GSoC Idea: Inkscape API Improvement
by Glimmer Labs 03 Apr '09

03 Apr '09

My name is Soren Berg and I wanted to propose a possible Google Summer of Code project and see what you guys think. I would like to use GSoC '09 to improve the scripting API of Inkscape. This is an area that has seen some major changes over the last few years in terms of extension support and verb passing but I still believe there is room for improvement. The extensions are very useful for making filters but don't (correct me if I'm wrong) really expose any of Inkscape's functionality. You need to use an entirely different set of tools to manipulate the XML data and pass it back. The verbs are very useful for batch processing and similar tasks, but the fact that none of them take any parameters or return results means that they are not ideal for scripting or otherwise interacting with Inkscape in a more in-depth fashion. I wrote a scripting console that exposed many Inkscape functions for programatically creating images and it was accepted for inclusion but it became harder and harder to support, largely because of the lack of any sort of API. It did show some very interesting benefits to controlling Inkscape programatically (like script-fu for the GIMP) though. I know there is some work going on with a Java based API but it seems to be mostly stubs right now. I could start working on this early as well since I have a job that wants to integrate software with Inkscape. What do you guys think? Obviously I haven't fleshed out my plans very much, and that is because I want to get some general feedback on the concept first. Thank you for reading, Soren Berg

Icons for "align nodes horizontally" and "align nodes vertically" are swapped
by worms invasion 03 Apr '09

03 Apr '09

Hello, This has been going on for a while I think in current SVN and is still present in r21009 (win32snapshot)... The "align nodes horizontally" function is assigned the "align vertically" icon, and vice-versa for the "align nodes vertically" function.

Affine Transformations in Python
by G33K 02 Apr '09

02 Apr '09

Hi, I' d like to ask if there is perhaps some sort of affine transformation library available to the Inkscape Python scripts? So far, I only found the file simpletransform.py, which is quite useful, but not very comprehensive. The transformation stuff already has excessive support in the Inkscape C++ code. Are there any Python bindings for that? Right now, I am primarily interested in getting pretty constructor functions for defining rotations and scaling, without having all the mathy matrix clutter in my code. If none are available, I could add those to simpletransform.py myself. Cheers, Gerrit -- http://www.fastmail.fm - And now for something completely different

Ubuntu nightly builds
by Ted Gould 01 Apr '09

01 Apr '09

Hello all, So I've gotten most of the way on getting a nightly build setup in a Launchpad PPA. It builds for the current, the previous and the next release of Ubuntu. What I'm particularly happy about is the package is "inkscape-devel" so it can be parallel installed with a stable version of Inkscape. Here's the PPA: http://launchpad.net/~inkscape-nightly/+archive I'm going to run the script by hand for a couple of days to catch errors but then Cory has graciously allowed me to run it on his server after that so it should become more regular. --Ted

I am thinking about doing a project on reading digits on licence plate of cars from a picture of the car. I have done considerable research on this project which involves both image processing and optical character recognition. Please let me know if you are interested in this project or any other requirements i need to fulfill. Thank You

Changes in rendering of lpe tests
by Jasper van de Gronde 31 Mar '09

31 Mar '09

Can somebody knowledgeable in all things lpe have a look at the new rendering results for the "lpe shapes.svg" and "lpe-knot.svg" tests? Links to the SVG files in SVN can be found on the results page: http://home.hccnet.nl/th.v.d.gronde/inkscape/ResultViewer.html The existing references are also in SVN: https://inkscape.svn.sourceforge.net/svnroot/inkscape/gsoc-testsuite/tester… (There are a few other "New" results shown on that page, but that's just due to a change in the missing file image, and the references have been updated already.)

Fwd: Google Summer of Code: Potential Student Applicants: "***Very Important***: Submit your Proposals via the 2009 site *now*"
by Alexandre Prokoudine 31 Mar '09

31 Mar '09

For your consideration ---------- Forwarded message ---------- From: Vaughan Johnson <vaughan@...2172...> Date: Wed, Apr 1, 2009 at 12:08 AM Subject: [Audacity-devel] Google Summer of Code: Potential Student Applicants: "***Very Important***: Submit your Proposals via the 2009 site *now*" To: Audacity Developers List <audacity-devel(a)lists.sourceforge.net> Leslie Hawthorn, who runs GSoC, just posted to the mentors announce list a msg with subject "***Very Important***: Get Your Students to Submit their Proposals via the 2009 site *now*". If you're planning to apply, go ahead and do so now. This way, you can start to get feedback from us and Google can get an idea of how many students are applying. We fully expect applications to be iteratively refined before the deadline, so don't worry if your application is not complete, submit it now, so we can give you feedback on how best to complete it. The other reason to do so, LH explained, is because it is vital information in considering whether to extend the application deadline, which is under consideration. Thanks, Vaughan

GSOC: Dynamic tints, tones and shades based on a named 'anchor' color
by Frederik Fabritius 31 Mar '09

31 Mar '09

Hi Inkscape developers I hope to participate in GSOC 2009 and have written my project proposal in the bottom of this message. I have (very) briefly outlined the idea in an email to Jon A. Cruz, and he did not seem dismissive to this idea ;) This has some overlap with existing blueprints in Launchpad, so this project could be complementing current ongoing efforts in the code base. It seems that the work has barely started yet, so i hope my work will speed up things in this regard. My project proposal is below, and i have signed up for GSOC 2009 (name: frederikf) but not submitted my proposal, since i wanted some feedback from you guys first. Best regards, Frederik ------- Project proposal ------- Name: Frederik Fabritius Project: Dynamic tints, tones and shades based on a named 'anchor' color Project proposal: The idea is to have named colors which objects can inherit as fill or stroke color, so when changing the color value of the named 'anchor' color, all objects inheriting it will change color accordingly. As well as inheriting the exact 'anchor' color it should also be possible to specify an object color as 'linked' a tint/tone/shade of the 'anchor' color. After having seen this in Xara and Adobe Illustrator i immediately thought that Inkscape was missing this feature. I saw on Launchpad that two blueprints had been written, but not much had been implemented: https://blueprints.launchpad.net/inkscape/+spec/named-color-swatches https://blueprints.launchpad.net/inkscape/+spec/color-groups Jon A. Cruz 2008-06-03: This sounds like an overlap of the named color stuff, Open SwatchBook, and what I've been calling "live colors" but are actually dynamic tints, tones and shades based on an 'anchor' color. I have briefly emailed with Jon A. Cruz about this proposal who has said he was just begun implementing part of the ground work for implementing named swatches. I was thinking that this GSOC project might offload/complement some of Jons work. I think the concepts could be extended by not only linking shade/tint of a color, but also looking into linking colors across the spectrum such as complementary/triad/analogous colors as explained here: http://www.tigercolor.com/color-lab/color-theory/color-theory-intro.htm I consider this extension to the concept, to be out of scope of the GSOC delivery. Final deliveries: A named swatches dialog A property editor dialog to edit the color in the swatch, which also allows one to specify a 'linked' tone/tint/shade to a named 'anchor' color in the swatch. These should support being stored in Jon's "Open Swatchbook", if it makes sense in the given timeframe. I know Jon has considered implementing an additional color picker, but i plan on limiting the delivery to support the current color pickers implemented in Inkscape and working out the details with the mentor associated for the project. Inkscape Questions When did you first hear about Inkscape? Have you used Inkscape before? If so, for what sorts of things? Ive used Inkscape mostly for illustrations for the past three years for student projects at my university. I have also used it for website mockups and for doing layouts for event invitations and the like. About Yourself I am currently writing my master's thesis at the Technical University of Denmark where i am writing audio processing on the GPU. I have a 2 week planned vacation where i was going to bring my laptop and work on the project as well. My main programming language is python, but have done various projects in C++, C# and java.

Inkscape logo license
by Nicolas Dufour 31 Mar '09

31 Mar '09

I know it has already been discussed before, but I can't find any conclusion. We (me and Elisa) need to use the Inkscape logo in two contexts: . to create a customized logos for the inkscape-fr and planet Inkscape-fr websites; . in a book we're currently writing, adapted in our drawings. All of these uses need that the logo allows modifications, and the last one no commercial limitation. We plan to release our work very shortly and we really need to know what to do. Thanks. -- Nicolas
