The win32 build, which was broken for the weekend, is working again. I just made a "manual autobuild" again, so that we can see how it looks on Windows: http://troi.titan-aeu.com/~rjamison/inkscape/builds/ Bob

Regarding the serialization of Spiro control points
by Fred Brennan 28 Mar '22

28 Mar '22

Greetings, I write from the FontForge project. Of particular interest to me is the Spiro spline feature, which was originated around ten years ago by Raph Levien. One thing I'd like to add, (which would benefit both our projects,) is the ability of FontForge to understand the Inkscape Spiro serialization format. However, there are several things about the format which to me as an outsider appear to be defects serious enough that I have no idea how to even *import* these splines correctly, much less export our Spiro splines to this format. I would very much like to support the _de facto_ standard Inkscape has originated of supporting Spiro in SVG, but I am lost. George Williams, FontForge's original author, noticed this defect over eleven years ago.[1] Things are virtually unchanged since then, I checked `git blame`. Spiro has five point types, not including beginning and ending points. They are: * G4 curve (o) * G2 curve (c) * Corner (v) * Left Constraint ([) * Right Constraint (]) The ASCII single letters are the normal method of Spiro serialization, as championed by Raph Levien and by us in FontForge. Inkscape seems to create what I will call a "pseudo-SVG path". So, it is not really an SVG path, but rather is an SVG path which undergoes transformation into the typical Spiro format. Inkscape stores this in the "original-d" attribute. So, given a Bezier spline with control points defined as (x, y, c1, c2), Inkscape interprets a control point with only (x, y) to be a corner, meanwhile a control point with all four is a G4 curve, and (x, y, c1, NULL) is a left constraint while (x, y, NULL, c2) is a right constraint. I can probably overcome this, although George Williams was right to be skeptical of this format. There is no way I can see to define a G2 curve in this strange "original-d" format. Thus, this email. I write to ask a few things. I suppose first of all, what are the chances that we can convince you guys to store Spiro splines in plate[2] format, or another widely accepted Spiro serialization format? Second, if we cannot convince you to do that, how do I export FontForge spiros which contain G2 control points to Inkscape's original-d format? It's not possible, yes? So should I just silently fail and save them as G4? The curves will not be the same if I do that. Should I disallow export to SVG w/Spiro if glyph contains G2 control point? That seems a steep cost that will just confuse my users, so perhaps I should abandon the whole thing if it comes to that. Cordial regards, Fredrick Brennan (@ctrlcctrlv) [1]: https://narkive.com/63FADpG3.4 [2]: https://levien.com/garden/ppedit/README, section "Plate files"

Hi, I am Saurabh Singh from IIT Roorkee, India. I am pursuing computer science here. I was doing graphic designing as an hobby when I came across Inkscape application and really liked it. I want to contribute in Inkscape for GSoC 2020, but I'm confused about the project ideas given in the idea list. Can someone help me with this? Thank you Regards Saurabh

LGM Hackfest in Rennes, France
by Marc Jeanmougin 21 Feb '20

21 Feb '20

Hi everyone, we will likely have our next hackfest in Rennes, France, just before LGM in May. LGM is May 26-29 and it's likely the hackfest will last for a few days before it (last hackfests lasted from 3 to 5 days). All contributors* are welcome and encouraged to attend the hackfest! Financial support will be available, but please sign up in advance (either by answering to this email, or by adding yourself on https://wiki.inkscape.org/wiki/index.php?title=Hackfest2020_Rennes_Attendees ), to account for possible limited hosting capacity and to allow expense (and logistics) planning. I hope to see lots of you there :) -- Marc (* not just code, a hackfest can be a productive time to write a tutorial, discuss some UX, progress on a translation, or coordinate some media outreach, for instance!)

"Getting Started with Development" instructions
by Maximilian Gaukler 18 Feb '20

18 Feb '20

Hi everyone, I am about to update the "getting started" instructions for new developers: https://inkscape.org/develop/getting-started/ If you have any further suggestions, feel free to answer. I'd like to consolidate all changes into one big edit because every change needs to be translated. Here's my list of changes: - git SSH -> change to HTTPS (as discussed a few months ago) - "Install build dependencies": replace old "apt-get" instructions with the new script from inkscape-ci-docker. Download and run the script to install all requirements: wget -v https://gitlab.com/inkscape/inkscape-ci-docker/raw/master/install_dependenc… -O install_dependencies.sh bash install_dependencies.sh --recommended - "/usr in the example" -> "in the example, it is installed in inst/ inside the source folder" - "Versions <= 0.92" -> remove from tutorial, move to Wiki remove mentioning of autotools, as CMake is now the default - do not mark optional arguments with "[ ]" so that copy-paste into the shell works. Also, omitting some of these arguments (e.g. ccache) will horribly slow down compilation, so they aren't truly optional. Instead, just add a note that these arguments may be omitted. - after changes are published: remove redundant info from the Wiki page https://wiki.inkscape.org/wiki/index.php?title=CompilingUbuntu Have a nice weekend, Max

Hi Elisa, thank you :) for organizing and for the invitation. There's going to be an Inkscape Board Meeting next week Friday evening at 19:00. I think the Rennes Hackfest will be a topic on the agenda then. Would you or Cédric maybe have time to join the Board for a bit of planning?

LGM: About two weeks left for entering your talk/workshop submission!
by Maren Hachmann 01 Feb '20

Hi everyone, this is a reminder that you can still submit a proposal for a talk, lightning talk, hackathon, Birds-of-a-feather meeting or workshop for this year's Libre Graphics Meeting. LGM will take place in Rennes (Brittany, France) from May 26-29 2020. The deadline for your submissions is February 17th. More info about your submissions: https://libregraphicsmeeting.org/2020/en/program.html Info about the venues: https://libregraphicsmeeting.org/2020/en/venue.html The main focus of this year's event is 'Getting Things Done'. The organizers explain that this "means explaining how you manage to attract more contributors, how you manage the tasks of development, fixing bugs, the general directions that you want to take your project, and how you interact to accomplish this. You might even talk about ideas you have but have not yet implemented. Part of Getting Things Done means sharing ideas and methods with each other and with artists." They are looking for: " * Presentations attracting new contributors to projects * Information about how your project "gets things done" * Productive workshops to improve and extend software * Technical presentations and workshops for developers * Showcases of excellent work made using Libre Graphics tools " There's also an Inkscape Hackfest planned to take place either during, before or after LGM, so stay tuned ;-) Maren
