win32 build working again
by Bob Jamison 08 Apr '24

08 Apr '24

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"

Inkscape developer meetings
by Marc Jeanmougin 25 Jul '20

25 Jul '20

Hi all developers, during recent discussions, we have been pondering the idea of regular dev meetings, and discussing them again on the live today, we are suggesting to hold them every eight days (so that if someone has an agenda problem with a day of the week, it'll still be okay for most of the meetings) . The idea for these meetings would be to talk about the development of Inkscape code informally, discuss bug reports we have been working on, recently raised regressions, etc, so that we could help one another if needed and get a wider sense of who is working on what area, and how things are progressing overall with features or releases in mind. Tentatively, we could hold a first meeting on August 6th 5pm UTC (24h before next board meeting ?) If you have any remarks about this, feel free to voice them :) Thanks everyone! -- Marc

Hackfest 2020: Developer Day
by Martin Owens 23 Jul '20

23 Jul '20

Dear Developers, This coming Saturday we are continuing are hackfest sessions with our developer day. If you are a developer, please come along at any point during the day starting at 4PM UTC and ending at 10PM UTC. There will be a meeting to talk about Inkscape's development specifically will be at 5PM UTC hosted by Thomas Holder, one item to talk about is if the developer team should meet once a month like other teams do. The rest of the day we will be looking at merge requests together. Going through some code and doing some presentation style hacking. Expect a lot of screen sharing! Let me know if you have anything specific you'd like to present before Saturday. Thanks everyone! Best Regards, Martin Owens Hackfest Organiser

gitlab.com gold group features
by Marc Jeanmougin 14 Jul '20

14 Jul '20

Hi all, this is a short "what do you think about this?" message about gitlab. Current state of things : we currently use gitlab on their "gold" plan which does include proprietary extensions to the free software gitlab core (those features are scoped labels, multiple assignees, related issues (/duplicates), multiple issues boards, exceptions to protected branches, push rules, merge approvals). By "just asking", we could also have access to group-level gold features, such as Epics which are like meta-issues to track releases or big feature plans ( https://docs.gitlab.com/ee/user/group/epics/ ) and Group milestones (instead of having per-project milestones) The question is simple : should we ? (Pro : we get access to it; Cons : it's asking to use proprietary features, which is not something we usually do) -- Marc

Quick update on scribus pdf. current screenshots.

11 Jul '20

here's the current screenshot: https://i.imgur.com/T5awaBn.jpg and of the work to be done: https://i.imgur.com/ccU08hN.png i have to do a grid / form layout and some elements, which is trickier than it sounds. more tricky than freee-flow text. i may decide are best left free standing and not in any particular editable layout.

PDF and patents, feel free to ignore this if it's touchy.
by NASA Jeff 11 Jul '20

11 Jul '20

Hi, I'm currently writing an import filter to import free flow pdf text into Scribus for editing but i'm aware that there's no free pdf editor worth it's salt because pdf is patent encumbered. as a result all pdf editors that let you edit free flow pdf text are quite expensive and the free versions often limited by watermarks. anyhow, i hope i've avoided any patent issues as layout and fonts used bare no resemblance to anything pdf uses as I aggregate all the text and use Scribus's quite advanced layout engine to do the bulk of the heavy lifting with some vaguely intelligent aggregation code to aggregate the text in the filter. anyhow, can anyone give me a heads up on pdf and patents?
