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.

Inkscape Matrix Space
by Ted Gould 16 Aug '21

16 Aug '21

Hello, There is a new beta feature the Matrix folks are working on, and after being pinged about it by jabiertxof I setup Inkscape to use it. It basically allows grouping of the Inkscape rooms to get a UX that is closer to Slack/Discord/etc. Feature description: https://element.io/blog/spaces-the-next-frontier/ Generally, since it is a beta feature, I don't want to put it on the webpage/social media/etc yet. But it would be useful if folks who have Matrix accounts and are willing to enable the beta feature could test it out. I believe if you click this, you will be able to join: https://matrix.to/#/#inkscape:matrix.org If you have any issues joining or any recommendations on how to configure it you can reply here, ping me in one of the chats, or DM me on Matrix, @ted:gould.cx Ted

Meeting Today
by doctormo＠gmail.com 12 Aug '21

12 Aug '21

Dear all, Our Leadership Committee meeting is today¹ and it would be great to have you attend. Each meeting will be recorded so people who can not come will be able to watch the discussion later. This meeting's focus is going to be on making sure we can include more people in the definition of "The Inkscape Community" for the purpose of voting. I've put together this agenda: 1. Moving the canonical membership list to the website 2. Requesting from the SFC a change in agreement to define this new list as the list of voting members. 3. The remaining time we can talk about the mechanisms by which people get added to the list (see continuation of previous discussions). I expect the second item will produce a vote which will be sent to the mailing list. But we'll see how the discussion goes. Thanks everyone! Best Regards, Martin Owens Inkscape Leadership Committee ¹ https://inkscape.org/cals/event/30/

PLC Meeting this Thursday
by Martin Owens 09 Aug '21

09 Aug '21

Dear all, A remember that this Thursday we have a big blue button meeting. This month I'd like to have us decide on the membership problem. The question is: "How should we ask the SFC to change our agreement, to include all inkscape contributors" the goal for the meeting will be to put together the vote email which hopefully will be sent at the end of the meeting. Times and links: https://inkscape.org/cals/event/30/ Please do come if you'd like to be involved in the discussion of inkscape membership. Best Regards, Martin Owens
