LGM 2013
by Alexandre Prokoudine 04 Feb '13

04 Feb '13

Hello team, As you probably already know, registration for LGM 2013 is open, and talk proposals can be submitted. The event is taking place on April 10-13 in Madrid. See http://libregraphicsmeeting.org/2013/. LGM used to have a nice attendance by Inkscape team in 2006-2010, but then, AFAIK, things have changed. Has anybody already made up their minds to participate this year? If you did, I'd be happy to publish news and invite community to attend the event, so that they could meet you in person.

Pointers -> references
by Johan Engelen 30 Jan '13

30 Jan '13

Hi all, A code snippet from trunk: void srgb_to_linear( double* c ) { if( *c < 0.04045 ) { *c /= 12.92; } else { *c = pow( (*c+0.055)/1.055, 2.4 ); } } Alright, this method should not do a NULL check for performance reasons (I assume). But, shouldn't we use a reference in this case then? To signal clearly that the method does not accept NULL pointers without crashing: void srgb_to_linear( double &c ) { if( c < 0.04045 ) { c /= 12.92; } else { c = pow( (c+0.055)/1.055, 2.4 ); } } I'm trying to reduce the number of crashes due to simple NULL pointer crashes. I find such bugs satisfying to fix because it takes really only 1 minute to locate the bug and 1 minute to fix and commit it, but........ Ciao, Johan

dxf2svg extension
by Kris De Gussem 30 Jan '13

30 Jan '13

Hi all Upon crawling through the source code for memory related issues, I noticed some serious issues in the dxf2svg code. Modifying the code (at least in entities2elements.cpp) did not result in recompilation and apparently the code has not been looked after for years (see [1]) and was since long excluded from the building system ([2], [3] and [4]). Is there still some purpose for the code or could we drop the dxf2svg extension code from the source tree? Regards K.

Drawing to Canvas
by Dennis Coyle III 29 Jan '13

29 Jan '13

Hi, I am new to developing for inkscape and was wondering about drawing to the canvas. I've been digging through the src and have figured a few things out but I am still unclear as to which #include files I need add specifically and what the proper functions to call are. Any help would be much appreciated. Thanks, Dennis

pathv_to_linear_and_cubic_beziers, only to linear?
by mathog 25 Jan '13

25 Jan '13

Is there somewhere in Inkscape a function equivalent to: pathv_to_linear_and_cubic_beziers() which only outputs a polyline/polygon instead of a polybezier? The output format I am working on now has the former types, but not the latter. Thanks, David Mathog mathog@...1176... Manager, Sequence Analysis Facility, Biology Division, Caltech

Ideating
by Arshdeep Singh 23 Jan '13

23 Jan '13

I have a new idea to do something in Inkscape that will help the artists a lot. * * *For the same I have been digging into the files:* fill-and-stroke.(cpp+h) paint-selector.(cpp+h) fill-style.(cpp+h) I could figure out all the details of how the FiLL and STROKE dialog box is drawn plus how it interacts with the objects. What I don't get is the code where the changes are actually applied to the selected objects on the canvas(desktop). *Facts I already know:* 1.) in Inkscape, there are two representations of the document being worked on: Object and XML. 2.) Changes in the XML Representation is automatically reflected in GObject Representation but not vice versa. Please help ! -- demicoder

Mac OSX 0.48.4 RC3

Mountain Lon: http://rapidshare.com/files/1736402100/Inkscape-r0.48.4-r9943-10.8%2B-x86_6… Lion: http://rapidshare.com/files/3930886749/Inkscape-r0.48.4-r9943-10.7%2B-x86_6… This RC has the following features: - clipboard now fully working. The problem was inside the gtk2 library, and I fixed with this patch: https://bugzilla.gnome.org/show_bug.cgi?id=692123 GIMP and Darktable would benefit from this patch too. - OSX Menu fully functional with OSX-style mnemonics - uniconverter 1.1.5 + sk1lib 0.9.1, cdr import works great. - ghostscript bundled with the app: importing postscript works great - "open recent" working in Lion release too Problems I see: - the context-menu (right click on object) lack the "Cmd" mnemonic. This is a gtk problem. Mnemonics are correct but gtk lacks the symbol/icon for the Apple/Cmd key. I think it might be better to leave it for the gtk2/quartz team to fix this. Please let me know how it works for you, Valerio

Inkscape and clipboard (mac and others)
by Valerio Aimale 18 Jan '13

18 Jan '13

Re Inkscape clipboard, I believe there are two major problems : 1) General to all platforms, the fact that Inkscape spends time at exit, putting items on the clipboard: I believe that Inkscape current behavior is the correct one. Placing items on the clipboard is an expensive operation. Most operating systems have switched to a "delayed clipboard request fulfilling" model: an app offers items on the clipboard, at the user request, but does not actually pass them to the OS. Only when another app requests the clip, the original app fulfills the request. On exit, if the app owns the promised items on the clipboard, the OS will request to fulfill placement of items on the clipboard, to make them available to other apps. The reason for that behavior is that it makes apps look nicer. If all "copy" requests were to be materialized in the clipboard immediately, the user would have to wait a significant amount of time when he/she presses Cmd-C. It is especially true of Inkscape. Inkscape's cut and past operations are especially expensive, because the have to go through uniconverter. By delaying clipboard requests fulfillment, the user as a better experience: when he requests a paste in another app, the app who own the clipboard item is the the background and can fulfill the request at any speed, without annoying the user. Materializing items in the clipboard at exit does not annoy the user, because the user is focus on other activities and does not mind a rather slow app exit. 2) Mac specific: Inkscape+quartz cannot interact with the clipboard, due to the fact that the gtk library + quartz backend does not do a proper job of translating mime-types to Uniform Type Identifier, and vice-versa. The patch below, should fix properly gtk2+quartz, but I'm still testing it.

Coding style: const
by Johan Engelen 18 Jan '13

18 Jan '13

Hi all, Inspired by a blog text, I've spent some time adding "const" in a number of places. Adding const tends to spiral out of control if it was not used when code was written, meaning that you will have to add const in many other places where it should have been when it was first written. Please be very aggressive in adding "const" to any code you write. It will help us understand code better and will prevent bugs from creeping in. If "const" is new to you or you're a bit rusty on the topic, read this: http://www.cprogramming.com/tutorial/const_correctness.html Thanks a bunch, Cheers, Johan

Extensions tutorial
by Alex Valavanis 16 Jan '13

16 Jan '13

Hi everyone, I've been asked by a friend to give a talk/tutorial about Inkscape Extensions scripting for a local Python users meeting. It's a slightly daunting task for me, given that (a) I'm way more comfortable with C/C++ than Python (b) My involvement with the extensions subsystem has been pretty minimal! I'll happily put something together myself, based on the guidance on the Wiki, but if anyone already has any additional useful documentation/slides/tutorial material that they would like to contribute, that would be very helpful, and might even encourage some new contributors to the project :) Thanks!

Inkscape and Mac OSX menu integration
by Valerio Aimale 15 Jan '13

15 Jan '13

~suv, thanks as always for your insightful comments. Sorry for the belated reply, I've been busy with work. 99 times out of 100, refactoring is best. However, there are exceptions. Refactoring the menubar machinery in a way that works for all platforms is a major undertaking. It would be a significant investment of time. I think it would be nice to be able to provide a 0.48.4 release to the Mac users out there, who have been left behind for quite some time. I've come up with a solution that is not a hack, but not even refactoring. As a matter of fact, Inkscape has already 80 % of the code needed to work with a unified menubar. Would you, Victor, or any other willing test this version: https://rapidshare.com/files/2954353212/Inkscape-0.48.4-10.7%2B-x86_64.dmg It has a unified MacOSX menu for all windows/document/views. I don't know, however, what the unified menu does to dynamic menu items. Check marks are there and they seem to be ok for me. This version has also a working python installation. The application menu Quit item is not yet integrated with the app. It will be soon. ~suv, I've seen you comments in the bug reports and will reply, as time permits. Valerio > Commenting here even though the topic is quickly getting way above my > head: Personally, I wonder whether it's really about adding some hack, > or more about efforts at refactoring some of Inkscape's code base?

Feature request, export a svg to a multi resolution icon
by Justin Dearing 14 Jan '13

14 Jan '13

Hello, I created a 512x512 svg image to serve as the "master" logo and icon for poshrunner. I then use inkscape from the command line to make png renderings at 256,128,64,48,32, and 16 pixel square resolution, and then use FreeImage to create a single ICO file that gets embedded into the final ico. This involves two powershell scripts: https://github.com/zippy1981/AppDomainPoshRunner/blob/master/art/buildart.p… https://github.com/zippy1981/AppDomainPoshRunner/blob/master/art/buildIcon.… It would be nice to simplify this process. Could inkscape add multi resolution ico export support? For the resolution it could be a series of checkboxes for the accepted resolution (btw as of Vista the ICO format supports 256x256). For the scriptable command line version the syntax could look like: inkscape --export-ico=foo.ico--export-ico-resolutions=16,32,48,64,48,128,256 foo.svg Regards, Justin Dearing

Can we list the Chocolatey (apt-get for windows) package for InkScape on http://inkscape.org/download/?lang=en
by Justin Dearing 13 Jan '13

13 Jan '13

Hey all, I took over maintenance of the chocolatey (http://chocolatey.org) package for inkscape. Chocolatey is basically yum/apt-get/fink/etc for windows. I have a request and two offers. My request is that you list the package on the download page. My first offer is that if you deem it appropriate I will make someone on the inkscape core team a co-owner of the package. My second offer is to integrate the package building into the inkscape windows build process if you deem that appropiate. Let me know your thoughts. Regards, Justin Dearing

Patch that allows use of Meta key on Mac OS X and all platforms
by Valerio Aimale 09 Jan '13

09 Jan '13

I've submitted this patch https://bugs.launchpad.net/inkscape/+bug/1097539 that activates the Meta (or Apple or Command or Windows Flag) key as modifier key. It allows to have Mac-like menu accelerators (Command-C for copying, Command-V for pasting, etc.) After applying the patch and compiling/packaging, the file share/keys/mac.xml has to be copied as Inkscape.app/Contents/Resources/keys/default.xml The file mac.xml is a copy of default.xml where I brutally found all occurrences of 'Ctrl' and replaced them with 'Meta'. I'm sure it needs a more careful approach. Valerio
