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

Rounder Extension
by Jabiertxo Arraiza Cenoz 22 Dec '15

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

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

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.

Connecting 2 paths smoothly in code
by Papoj Thamjaroenporn 14 Dec '15

14 Dec '15

Dear Inkscape-devel, I have these two paths (Geom::Path, or two Piecewise<D2<SBasis>> if you want), and I would like to join them smoothly (C1, to be precise), in code. Is there an API provided to achieve this task? What I am trying to achieve is obvious to do using Node Tool by first “Join selected nodes" and then “Make selected nodes symmetric”, but I am not sure how to achieve this in code using Geom::Path easily because it doesn’t have a notion of “node” to manipulate. I can setInitial() or setFinal() or setPoint() manually, but since the feature in already there in the code, although in the parts I do not yet understand (PathManipulator), I figured I should ask. Thank you! Regards, _______________________ Papoj "Hua" Thamjaroenporn papojt@...3117...
