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

Hi to all, I just made a new extension to round to a fixed decimal position some data in SVG. Currently it round optionaly: Nodes, with another optional check to move handles along Handles Stroke width Height Width Position X Position Y https://inkscape.org/en/gallery/item/7126/ Ping me if think some atribute important to add( ex:transforms, viewbox...) Cheers, Jabier.

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...

C++ Exception Handling
by Rodrigo Bonifacio 15 Dec '15

Dear all, (apologies if you receive multiple copies) We are investigating the use of C++ exception handling constructs in well known open-source C++ systems, and have published some results in the last International Conference on Source Code Analysis and Manipulation [1] We are expanding this research to a broader community, so I kindly invite you to answer our new version of the survey at: https://www.surveymonkey.com/r/SXCB7WJ Sincerely, Rodrigo Bonifácio (on behalf of the authors of this research effort).

Developing on Mac
by Michael New 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
