Specifying color fonts
by Tom Lechner 22 Jan '16

22 Jan '16

Hi, Is there currently in Inkscape a way to specify exact fonts, like specific font files? If I understand right, would this mean support of "user fonts" as specified by CSS3 Fonts? I've been working on using color fonts made from font layers (where each color layer is a different font file), but the layer fonts I can find all specify family names and styles in such a way that it seems impossible to specify them in Inkscape. Is there any planned native support for color fonts, either manually layered, or opentype svg/colr/cpal color fonts? -Tom ---- laidout.org tomlechner.com

Inkscape 0.92 and Converting Inkscape to CMake
by Bryce Harrington 19 Jan '16

19 Jan '16

CMake is a key goal for the Inkscape 0.92 release. We're close, but some important work still remains. Are you familiar with CMake? It's important not only that we convert the codebase, but that we also install our developers (i.e. YOU!!) with adequate cmake know-how to be able to update stuff as needs arise. Is CMake something you've not yet learned? I've written up a little Inkscape-specific tutorial / class to give you the basics. Please put it on your near-term todo list: http://wiki.inkscape.org/wiki/index.php/Working_with_CMake Once you're ready to tackle some cmake work, please take a look at my write-up of cmake tasks that I think we need to get done: http://wiki.inkscape.org/wiki/index.php/CMake_Tasks I've organized that page by tasks that I feel we need to get done for 0.92, versus ones that have to be done post-0.92 (since they'd break the autoconf stuff), and minor tasks that can be safely done whenever. Thanks for lending a hand to helping with the CMake work. My dream is that by achieving this conversion, we'll be able to unify a lot of our platform-specific packaging. Effort that currently is divided between linux, osx, and win32, will be able to be merged so we can better collaborate with packaging generally. Bryce

Re: [Inkscape-devel] Quality of gradients.

The EMF export function supports simple gradients as descriptions (high & low color values, scale and direction of linear gradient) and so are not quality limited in this manner. Perhaps in some instances you could export to EMF and then render from that in another application which doesn't have the 8bit limit? Unfortunately there is no exact support for radial gradients in the EMF or EMF+ standards. Currently Inkscape emulates such gradients in EMF files with many small single colored elliptical slices. The best one could do with EMF would be to use the peculiar "triangle" gradient mode (Google "GRADIENT_FILL_TRIANGLE") to emulate a radial gradient. Then instead of rings it would be a lot of small wedges, each with its own part of the gradient. At the moment there is no code in Inkscape to do this. (EMF+, which is not yet supported at all in inkscape but is coded into libUEMF, has something called a "Path Gradient Brush" which is essentially a bunch of these triangle gradients merged, so that instead of specifying a lot of triangles, one specifies a center point and a path.) Going this route would be a one way trip, since the code for working back from multiple triangle gradients to a radial one would need to be pretty clever to look for and detect this sort of clustering and arrangement of gradients, especially since those EMF records need not be consecutive in the file. (Going from EMF+'s Path Gradient Brush to an SVG radial gradient would be easier because it would not have the multiple record problem.) Also an awful lot of these triangles might be needed to get a smooth looking radial gradient, that is, one that doesn't look like a set of nested polygons resulting from "contour lines" of constant colors. Perhaps slightly varying the angle in each slice would hide that effect a bit? Anyway, for future reference: EMF Triangle gradient (look about 1/3 down from the top) http://www.flounder.com/gradientfiller.htm EMF+ Path Gradient Brush http://www.codeproject.com/Articles/20018/Gradients-made-easy Regards, David Mathog mathog@...1176...

Licensing issues with Scour (aka 'Optimized SVG' output)
by Eduard Braun 12 Jan '16

12 Jan '16

Hi all, I'm posting here today hoping that we can finally resolve some licensing issues which recently emerged regarding the Scour extension for Inkscape (also know as 'Optimized SVG' output). I'll try to summarize the issue as good as possible so everybody is up to speed: * Right now we bundle an old version of Scour that is dual-licensed with Apache 2.0 license and GPLv2+. This dual licensing was only introduced in a very recent commit [1] when the original author Jeff Schiller agreed to re-license his code under the terms of GPLv2+ after license issues in Inkscape were brought up in a previous discussion [2]. However at this point there were multiple contributions to the Scour codebase by other authors who did not accept to re-license their contributions. This is why the re-licensing is likely to be void and the the current maintainer of Scour (Tobias Oberstein) decided not to apply the dual-licensing when switching over to GitHub with the project [3]. * I recently updated the Scour extension for Inkscape and want to merge these changes [4]. Obviously I followed Tobias Obersteins decision not to apply the dual-licensing, so the new version only has the Apache 2.0 License. * The open question now is: Can we bundle the Scour code with Inkscape and how to we do it? In my opinion this should not be a problem since Scour is an external module that is *indepentent* from Inkscape, e.g. license incompatibilities do not play a role here which is also the opinion of Tobias Oberstein (see [5] for details and references). Also most project members seem to agree (see comments in the merge request [4]) However If we don't want to follow this reasoning we have to decide on alternatives (especially since the code currently in trunk might well have an invalid license). I hope we can once and for all resolve this issue! Best Regards, Eduard [1] http://bazaar.launchpad.net/~scouring/scour/trunk/revision/222 [2] https://sourceforge.net/p/inkscape/mailman/message/32342425/ [3] https://github.com/codedread/scour [4] https://code.launchpad.net/~eduard-braun2/inkscape/scour/+merge/278387 [5] https://github.com/codedread/scour/issues/7

Inkscape is legally backed by the Software Freedom Conservancy, but SFC needs your help
by Dave Crossland 12 Jan '16

12 Jan '16

Hi Software Freedom Conservancy is the legal backer of Inkscape, but it is at risk of shutting down :( You can help make it sustainable by joining as a member for $120/year - just 14 people are needed! :) SFC is a not-for-profit charity that helps promote, improve, develop, and defend Free, Libre, and Open Source Software (FLOSS) projects. Conservancy provides a non-profit home and infrastructure for FLOSS projects. This allows FLOSS developers to focus on what they do best — writing and improving FLOSS for the general public — while Conservancy takes care of the projects' needs that do not relate directly to software development and documentation. http://sfconservancy.org/members/current/ lists the projects that they support, and the following are relevant to libre graphics: - Inkscape - Git - BOOST - a programming framework used in Inkscape - SWIG - another programming framework used in Inkscape, that enables Python scripting - K-3D - 3d modeling app - Outreachy - helps people from groups underrepresented in free and open source software get involved Just 14 more people needed to meet their membership goal this month, since those who sign up by January 31 count twice, thanks to Private Internet Access. Please consider joining as a member :) -- Cheers Dave

30 second video for the Inkscape project: New features & work from the past year
by C R 08 Jan '16

08 Jan '16

Okay, so there was not enough interest in doing the interview montage, so I'm back-burnering that one. :) So instead, let's show them what's new in Inkscape! I am doing a brief video commercial for the Inkscape project with updates from the last year. So what are you favourite Inkscape features/progress. This will replace the "two slides" at LGM, with something much more swish and polished to show off the hard work that's been done in Inkscape over the last year (starting from or around April last year). What I need: A list of your favourite new features in Inkscape (developed in the last year, or that will be finished and/or working by the date of LGM in April). I will combine them with mine and submit a video (after showing to everyone on this mailing list and #gimp to make sure we have all the facts right. Cheers. -C

Path Count Restriction in Division, Cut and Difference
by Martin Owens 05 Jan '16

05 Jan '16

I've committed a change to splivarot.cpp to remove the restriction which stopped our difference/cut/division functions from working on multiple paths. I was reading the forum post at http://www.inkscapeforum.com/viewtopic.php?f=5&t=20762 and it didn't seem to make much sense, so I did a few tests which I've posted here: https://inkscape.org/en/gallery/item/7216/ You can see we do the most sensible things already and the new functionality enabled by the commit doesn't seem to make a /lot/ of sense as far as I can see, but then I'd like to not artificially restrict the function because someone might find it interesting. The other hand is that there might be a more common sense way of doing the functions. Maybe by making a union first, or some other thing. But we'd first have to see examples on what users think they'll get when they run these operations on their multiple paths. Best Regards, Martin Owens

Re: [Inkscape-devel] [LGM] Fwd: LGM 2016: Call for Participation
by C R 03 Jan '16

03 Jan '16

I'm working on some proposals for talks this weekend. These are things I can talk about as a graphic designer who works with opensource software as a primary toolset. Inkscape will be featured in several of these talks, but I also desire to help the Inkscape Project with any materials and ideas for talks. What I'd like is to have (for the Inkscape Project) is a series of short videos where our current contributors to the project talk about what motivates them to contribute to Libre software. I will then compile these into a video (5-10 minute) video about Inkscape to present at LGM. This is a way for some of us who can not make it to London to talk about their role in Inkscape as a developer and/or professional user. To make it easy for the camera-shy among us, I'd suggest we do it in a format that resembles this mini commercial I did recently for a small Italian Restaurant: https://www.youtube.com/watch?v=GmPQ8FjRqr8 Something to notice is that the question comes up as text in the video rather than having a presenter ask questions, which makes it easy to ask and answer the questions as a regular conversation, rather than just an interview. Notice at no time did Carlo (who is tremendously camera-shy) have to look at the camera. He was always looking at me (off camera), and just answering my questions while ignoring the camera entirely. In this way I'm able to mix in relevant graphics, and cover mistakes or pauses to produce a professional quality edit with key points of interest. I will provide all editing, compositing, music, captioning (in the case where translation is needed). All materials will be provided in open formats as well for your tinkering pleasure. Any interest in this idea? -C On Sun, Jan 3, 2016 at 10:26 AM, Femke Snelting <snelting@...2319...> wrote: > All the best for 2016! > > ... and don't forget to submits your proposal for the upcoming LGM in > London! > > Deadline: *Sunday January 10th* > > > -------- Forwarded Message -------- > Subject: LGM 2016: Call for Participation > Date: Thu, 3 Dec 2015 15:46:29 +0100 > From: Femke Snelting <snelting@...2319...> > To: libre-graphics-meeting@...626... > > *Libre Graphics Meeting 2016: Other Dimensions* > > http://libregraphicsmeeting.org > > > The eleventh annual international Libre Graphics Meeting 2016 will take > place Friday 15th until Monday 18th April 2016 in London, UK.

Extension to export objects or layers to individual files: looking for testers/feedback
by su_v 03 Jan '16

03 Jan '16

Motivated by a request here on the mailing list wrt support for preparing animation frames from within Inkscape based on paths generated with Inkscape's 'Interpolate' extension, I began working on an extension to export a group of paths, or a selection of objects, to individual SVG files in November last year. Recent testing and feedback by Jabiertxo Arraiza Cenoz (thanks a lot!) introduced more features: export of layers or sublayers to individual files, additional export file formats (PNG, GIF) and optional creation of an animated GIF image of all exported objects (for bitmap-based export formats only). It also introduced a dependency on 'convert' from ImageMagick for the additional file formats. A snapshot of the current state of the extension can be downloaded for testing from the report in the bug tracker: * Bug #1530380 “Extension to export objects to separate files for ...” https://bugs.launchpad.net/inkscape/+bug/1530380 Some known issues and limitations are mentioned in the report description (and later comments) - any further feedback would be appreciated (I'm sorry for the lack of documentation / tutorial at this stage).

Colour Mixing
by Martin Owens 31 Dec '15

31 Dec '15

Dear Ink-devels, My friend has just complained that Inkscape doesn't have colour mixing. He's the first person to mention this functionality to me and I believe from his description the idea is that the colours can be mixed off canvas, where two color stops are selected and then a slider can move between the two. Has anyone ever heard of this? Best Regards, Martin Owens

Questions about EllipticalArc, BezierCurve, and Path
by Papoj Thamjaroenporn 24 Dec '15

24 Dec '15

Dear Inkscape-devel, I would like to convert a path that internally stores EllipticalArcs into a path with a bunch of BezierCurves. Is there a method that already does this? One way I think can be used is to convert path to pwd2, and convert back again to pathVector using path_from_piecewise() because internally it only uses Bezier curves, but I am wondering if there is a more direct way to do this. If I have a PathVector structure, and I know all Paths inside are connected to each other, is there an easy way to convert such PathVector into Path? Thank you.

Jenkins administration
by Johan Engelen 23 Dec '15

23 Dec '15

Hi all, Jenkins, our CI system, has been down for more than a month. It looks like the disk has filled up, and we need to do clean up / the build tasks should clean up after themselves better (I suspect it has to do with storing the results of too many older builds instead of just the current one plus a few recent builds). We need an administrator for Jenkins. Currently, I think only me and Bryce have access, which is not good enough. Who is interested in maintaining the automatic build/testing system? Of course, you can tailor the system to your own likes; there is much to be improved and I think all are open to whatever crazy plans you may have :-) http://jenkins.inkscape.org/ regards, Johan

Different sizes when cut and paste between Inkscape Trunk or Stable and FontForge
by Ivan Louette 23 Dec '15

23 Dec '15

Hello, Because of hardware problems with my main PC tower I went to my laptop where Inkscape 0.91 stable was installed while I mainly use Trunk usually. I noticed a difference in size in cut and paste from FontForge (the version 2 from Ubuntu 14.04 repositories) between Trunk and Stable 0.91. And I don't know if this is due to changes in units in Inkscape, and intentional or not. Thus I hesitate to fill a bug. However I will fill it if necessary. I ask me also if some settings I changed in my Trunk could cause this change. - if I cut a glyph in FF and paste it in Inkscape Trunk, its size in Inkscape is equivalent to this glyph typed at 750 pts - if I do the same to Inkscape Stable it's equivalent to the same at 800 pts ivan

How to properly fix bug and commit to Inkscape trunk
by Papoj Thamjaroenporn 17 Dec '15

17 Dec '15

Dear Inkscape-devel, I would like to fix a simple bug I found in src/helper/geom.cpp::pathv_to_cubicbezier(). The control points are not set correctly: Geom::CubicBezier b(cit->initialPoint(), cit->pointAt(0.3334) + Geom::Point(cubicGap,cubicGap), cit->finalPoint(), cit->finalPoint()); where it should have been: Geom::CubicBezier b(cit->initialPoint(), cit->pointAt(0.3333) + Geom::Point(cubicGap,cubicGap), cit->pointAt(0.6667) + Geom::Point(cubicGap,cubicGap), cit->finalPoint()); or more precisely: Geom::CubicBezier b(cit->initialPoint(), cit->pointAt(1./3.) + Geom::Point(cubicGap,cubicGap), cit->pointAt(2./3.) + Geom::Point(cubicGap,cubicGap), cit->finalPoint()); (The Geom::Point(cubicGap,cubicGap) shouldn’t really be there, but that’s a separate issue I described in another email.) I am not sure how to properly submit this. Do I follow the practice for bzr here <http://wiki.inkscape.org/wiki/index.php/Working_with_Bazaar#Test_branches_b…> and simply merge my fix (without a need for someone to review)?

Why does Inkscape automatically convert Cubic Bezier straight line to Line Segment?
by Papoj Thamjaroenporn 17 Dec '15

17 Dec '15

Dear Inkscape-devel, I am not sure if this is a design decision, but when I draw a cubic Bezier straight line on canvas, it would always get converted to a linear segment (no tangent node handles) automatically. This seems to happen in other scenarios (specifically in LPE) as well. This causes a little bit of an issue when I work on an LPE that requires having cubic bezier output, even for straight line, to maintain C1 smoothness across path segments. However, this automatic conversion will break my curve continuity, because I don’t have the tangent “node” to define for a linear segment that is connected to a cubic segment. In src/helper/geom, there is a method pathv_to_cubicbezier() that does this conversion, but it’s tricky: the tangent handles are somewhat “hacked” by adding small amount of offset to make the curve actually not perfectly linear. Although visually it maybe ok, but for scenarios that we care about precision, we may want strict linear segment to retain as-is, even though it’s in cubic form. Is there a way to turn this automatic conversion off? Regards, _______________________ Papoj "Hua" Thamjaroenporn papojt@...3117...

Developing on Mac
by Michael New 15 Dec '15

15 Dec '15

Hey Inkscape developers, I’ve spent the last several years both using Inkscape and working with C++, and I’d really like to contribute to the project now that I have some relevant skills. I develop on macs though, and I can’t seem to find any up-to-date instructions on building for mac. Can anyone point me to some current info? Thanks for the help, and thanks for everything you guys do. -Mike

Hi to all. Im starting a proyect and want link 2Geom to the code. Always have problem on compile because 2Geom files includes has a include base like "#include 2geom/point.h" and dont find it correctly. Any one know how to link 2Geom library whithout this problem, I dont want to change source code of 2geom. The code basic proyect -helloword- is here: https://code.launchpad.net/~jabiertxof/+junk/browup The error code on compile is Scanning dependencies of target 2geom [ 2%] Building CXX object 2geom/CMakeFiles/2geom.dir/affine.cpp.o /home/jtx/Development/browup/2geom/affine.cpp:9:26: fatal error: 2geom/affine.h: No existe el fichero o el directorio compilation terminated. 2geom/CMakeFiles/2geom.dir/build.make:62: recipe for target '2geom/CMakeFiles/2geom.dir/affine.cpp.o' failed make[2]: *** [2geom/CMakeFiles/2geom.dir/affine.cpp.o] Error 1 CMakeFiles/Makefile2:122: recipe for target '2geom/CMakeFiles/2geom.dir/all' failed make[1]: *** [2geom/CMakeFiles/2geom.dir/all] Error 2 Makefile:127: recipe for target 'all' failed make: *** [all] Error 2 Thanks in advance, Jabier.
