PCBmodE
by saar drimer 01 May '13

01 May '13

Hello everyone. I'm new to the list and wanted to introduce myself and talk about why I'm here. I developed a Python software for creating artistic and functional printed circuit boards. It's open source (Apache License) and based around JSON, SVG, and Gerber output (the latter for lack of any other more manageable alternative). I use Inkscape to draw the routing, and to move instantiated components around (everything else is created from information stored in JSON files). Before I continue, here's more info and some nice pictures: http://bitbucket.org/boldport/pcbmode http://boldport.blogspot.com My development mindset up to now was to not modify Inkscape or require plugins, and to use only what is strictly necessary, or what I cannot reasonably implement myself (auto-routing, complex SVG manipulation, etc.). This might need to change, as I'm realising that in order to make PCBmodE more useful to other people, it needs to be more tightly integrated with Inkscape. So I'm here to discuss the possibilities and hear your thoughts, advice, and criticisms. Here's more about me and my background: http://www.saardrimer.com http://uk.linkedin.com/in/saardrimer Thanks! saar.

GSoC 2013 Project Idea | Mayank Dehgal
by Mayank Dehgal 01 May '13

01 May '13

Hello! I am Mayank Dehgal, a student from IIT Bombay, India, currently a second year undergraduate in the Computer Science department. I am interested in working with Inkscape for GSoC. I have used Inkscape to present the designs of 2D games and animations I have created. I have been thinking for long about using the generated svg file for creating a 2D game engine, or for animating certain rigid bodies. Since the svg file is an xml file, we just store the information of different structures in the file. I have been using Box2D ( 2D physics engine) lately, and we just declare different bodies with their positions, gravity, density, shape, so that the physics engine uses the information and runs the simulation. I plan on adding various properties to the svg file through additions in the User Interface, and then using it with Box2D to create simulations and 2D games. Please give me feedback and suggestions regarding this idea. Thank you.

Build and hard link
by Martin Owens 01 May '13

01 May '13

Hey Devs, and more specifically Super Ted, I'm trying to come up with a script to process some of these merge requests more effectively. I've been keeping a trunk branch handy which is re-made each new pull so I have something up to date enough to work from and not have to wait for huge builds. So, I thinks to myself, maybe if I used bzr correctly and did a `bzr branch trunk bug174678 --hardlink`, ran the autogen and then hardlinked over all the .o files from trunk, I'd have a reasonable starting point. Turns out it's not that simple and make just wants to rebuild everything in the new branch anyway. I'm guessing it's checking some prerequisite's date stamp and I'm just not making sure it's touched. Script can be seen here: http://paste.ubuntu.com/5621102/ Any ideas? Best Regards, Martin Owens

DBus api signals
by cabieces julien 30 Apr '13

30 Apr '13

Hi, I have to produce a "plugin" for Inkscape. Python extension functionnalities are not enough for what I want to do so I came to try the DBus Api. With this one, I can communicate from my plugin to Inkscape but not in the other way. The only implemented signal is "ObjectMoved" but I need to know when Inkscape modifies a node, adds an attribute or things like that. I look after the dbus extension code and it seems that the signals that I want are described in proposed-interface.xml and are not yet implemented. Is there any way to achieve what I want to do? Is there further development forecast for dbus extension? Is this possible to propose eventually patch? Thanks for the reply

I wrote up a quick rack (linear) gear extension yesterday. https://github.com/braingram/inkscape_rack_gear I would like to add this to the inkscape extensions repository (on the wiki) and ask for any feedback. Thanks!

GSoC 2013: Unit Handling
by Matthew Petroff 29 Apr '13

29 Apr '13

Hello, My name is Matthew Petroff, and I am an undergraduate at Johns Hopkins University majoring in Physics and Computer Science. I've used Inkscape for about six years, and have also created SVG files by hand. I've been involved with FOSS for a few years now, namely Hugin [1] and, more recently, FontForge [2], mainly as a builder. For Google Summer of Code, I would like to improve unit handling in Inkscape. It is my understanding that Inkscape's current unit handling is scattered across the code base in various locations, and from personal experience, I know Inkscape's unit handling could use improvement. To start, I would refactor all of Inkscape's unit handling into one centralized location. I would then extend this unit handling to allow for easier use of "real" units, e.g. millimeters, both on the document wide level and for individual objects, as has already been outlined in a blueprint [3]. Thoughts? -Matthew Petroff [1] http://hugin.sourceforge.net/ [2] http://fontforge.org/ [3] http://wiki.inkscape.org/wiki/index.php/BlueprintRealUnit

Re: [Inkscape-devel] C++ification of the SPObject tree
by Markus Engel 29 Apr '13

29 Apr '13

Hi there, I removed those c++11 parts now and went on with c++ifying the SPEventContexts. These were even easier to convert, I should have started with them. As far as I can tell, Inkscape did not get any slower and memory consumption even decreased a bit. At least that's what /usr/bin/time -v inkscape -z share/examples/car.svgz -e car.png says. Btw, I found a little mistake in the source code: src/widgets/sp-attribute-widget.cpp:262:15: warning: use of logical '&&' with constant operand [-Wconstant-logical-operand] if (flags && SP_OBJECT_MODIFIED_FLAG) ^ ~~~~~~~~~~~~~~~~~~~~~~~ src/widgets/sp-attribute-widget.cpp:262:15: note: use '&' for a bitwise operation if (flags && SP_OBJECT_MODIFIED_FLAG) ^~ & src/widgets/sp-attribute-widget.cpp:262:15: note: remove constant to silence this warning if (flags && SP_OBJECT_MODIFIED_FLAG) ~^~~~~~~~~~~~~~~~~~~~~~~~~~ Maybe one of you can correct that as I don't have write access.

question about memory leaks
by insaner 27 Apr '13

27 Apr '13

i wrote up a patch ( https://bugs.launchpad.net/inkscape/+bug/1092374/comments/11 ) for https://bugs.launchpad.net/inkscape/+bug/1092374 but as you can see from the comment (hopefully not the patch itself) i dont have much experience with c++, gtk or inkscape programming, so i really want to avoid the potential of having created a memory leak with that. if someone could take a look and enlighten me a bit i would appreciate it. last thing i want is to be making inkscape a slow hog through my little fixes -- View this message in context: http://inkscape.13.x6.nabble.com/question-about-memory-leaks-tp4966734.html Sent from the Inkscape - Dev mailing list archive at Nabble.com.

message for tavmjong
by insaner 27 Apr '13

27 Apr '13

hi tavmjong, i saw the awesome work you did on http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/12104 so i thought you would be the guy to request a look at: https://bugs.launchpad.net/inkscape/+bug/168960 (and if possible, https://bugs.launchpad.net/inkscape/+bug/1064717 as well.. ) i included there a link to how gimp seems to do it.. but i just realized its not quite all there, so i looked up a little more info and found these as well: http://fossies.org/linux/misc/gimp-2.6.12.tar.gz/dox/fonts-commands_8c_sour… http://fossies.org/linux/misc/gimp-2.6.12.tar.gz/dox/gimp-fonts_8c_source.h… hope this is of some help. it would be a great feature to have for those of us who have fontforge open while working on a huge inkscape project that at times requires a refresh of the font list. thanks in advance -- View this message in context: http://inkscape.13.x6.nabble.com/message-for-tavmjong-tp4966720.html Sent from the Inkscape - Dev mailing list archive at Nabble.com.

HI all, Sorry if this is a noob question, but i am trying to build the tarballs for inkscape from trunk, and am running into issues. When trying to run "make dist", I get the following errors: make dist-bzip2 dist-gzip dist-zip am__post_remove_distdir='@:' make[1]: Entering directory `/home/.../source/inkscape' make[1]: *** No rule to make target `mkinstalldirs', needed by `distdir'. Stop. make[1]: Leaving directory `/home/.../source/inkscape' make: *** [dist] Error 2 is there a "mkinstalldirs" target? cheers, ryanlerch
