Survey: Default beabiour on clones with path operations
by Jabier Arraiza 02 Jan '18

02 Jan '18

Hi all: I just commit a branch [1] that convert shapes and optinaly clones to paths previously any of this path operations: Booleans, Stroke to paths, Object to paths, Combine and Break Apart. The cuestion is simple: ¿Whats is your prefered option about symbols? This is done in preference section and can be change by the user, but we are speaking about the default behabiour. A: Convert to path clones and apply the operation B: Retain clones in this operatios ignoring the operation Thank for take time to reply. [1] https://gitlab.com/inkscape/inkscape/merge_requests/159

Trunk PPA working - Merry Christmas!
by Alex Valavanis 25 Dec '17

25 Dec '17

Hi All, Hope everyone's having a nice holiday. I've fixed the Trunk PPA uploads. The issue was that since we moved to git, there is no longer a universal sequence number for the commits... in other words, every time we merge a branch, the auto-numbering got screwed up. The solution (albeit a bit ugly) was to move to time-stamps in the version string, as recommended by the Launchpad documentation [1], rather than using a commit log number. The version strings for the built package now take the form: 1:0.92.0+devel+{time} This expands to something like: inkscape-trunk_1:0.92.0+devel+201712242340~ubuntu17.04.1 So it's a bit messy, but it's still a unique sequential ID. Best wishes, AV [1] https://help.launchpad.net/Packaging/SourceBuilds/Recipes#Version_numbers_a…

holiday graphics for website?
by brynn 22 Dec '17

22 Dec '17

Hi Friends, I'm thinking about starting a tradition of making holiday graphics for the website. Like for example, today I spiffed up the logo for Inkscape Community with some lights (not twinkling, but maybe next year ;-p ). https://forum.inkscapecommunity.com/index.php I'm thinking of just something small and simple like that. Holly and berries, or something. We couldn't do exactly the same thing on the website, because the logo doesn't work the same way as IC. (plus it's pretty small) But there must be some ways to easily slip in some extra graphics into the website? Like maybe in the menu/navigation bar? (could they be red and green? or look like snow is piled on them?) Or the white space between the logo on the top-left and the search field on the right? I saw that cute Inkscape logo with a santa hat in the gallery (https://inkscape.org/en/~jiawhein/%E2%98%85inkscape-logo-christmas), and that's what got me started. But unfortunately, it has a solid white background, which I don't think could be used for the site. I requested either SVG or a transparent PNG, but no answer yet. I made some sort of straight lines of lights, one of which might fit in the white space at the top. But alone, they're hardly creative. Anyway, if someone could explain what those ways might be, where we could sneak in some cute graphics around holidays, I'll take the responsibility to put out a call for such graphics before each major holiday.....or maybe just 4 seasons? Or maybe holidays plus 4 seasons? (I still want to see more graphics on the site, in general. But that's a much bigger project which I can't take a leadership role right now. Well, not unless someone else wants to co-leader it?) Thanks for comments :-) All best, brynn

GDL broken under Wayland
by Tavmjong Bah 21 Dec '17

21 Dec '17

Hi, It appears that GDL (Gnome Docking Library) is broken under Wayland. >From what I've figured out, the problem is that Wayland doesn't have the concept of global windowing position which means that GDL doesn't know how to do drag-n-drop.[1] The blue "pseudo" window used to indicate where the window is while dragging does not change position. GDL doesn't seem to be under active development so I can't see this being fixed upstream soon. (There were a handful of commits last year, mostly for translation updates.) The code and our interface to it are rather complicated and it would probably take someone a considerable amount of time to fix it. It might be time to rethink how we handle docked and floating dialogs. Any ideas? Tav [1] https://blog.gtk.org/2016/07/15/future-of-relative-window-positioni ng/

Re: [Inkscape-devel] Embroidery extension
by Lex 18 Dec '17

Ah, I see. My machine (a Brother SE400) can't cut the thread and continue stitching. It's a pretty difficult limitation to work with. I try to avoid jumps whenever possible, and when I have to, I place jumps such that they're easy to trim by hand.

Neat idea, but as far as I know, there's no good way for an extension to modify keyboard shortcuts. The only method I can think of would be to kill inkscape, modify the preferences file, and restart. That seems like a terrible user experience. > > Question: - if the ice is white - how do you specify a thread change ? > The extension processes objects in their stacking order, lowest to highest. If it sees a color change from one object to the next, it automatically inserts a thread change instruction in the output file.

Spin slider widget, redux.
by Tavmjong Bah 16 Dec '17

16 Dec '17

Hi all, I've taken into account all the feedback and have developed a little test program that shows of a number of solutions to replacing the Gimp Spin Scale widget. A gzipped tar file of the source code is attached so that you can try out the solutions (should be trivial to compile on Linux if you have the Gtk3 libraries). Not all of the solutions fully work as I didn't take the time to make them... but you should be able to get a feel for them. If you run in debug mode (see README) you can interactively add CSS. I've include an example CSS file you can paste into the debug window (ignore the colors, they were just for experimenting). I've also attached PNGs of the widgets with and without the extra CSS. The five solutions, from top to bottom, are: * Custom Gtk::Range widget couple with Gtk::Spinbutton: This is my current favorite. It works quite well, methinks. Use the 'Alt' key to get into fine adjustment mode. It was rather simple to implement. Could be refined further (add styling properties, rounded corners, etc.). * Gtk::Scrollbar coupled with Gtk::Spinbutton: Works rather well, but doesn't show as well the current value. Using a narrow "slider" prevents it from covering up the text (text not implemented yet). I didn't know it before, but if one clicks on the slider and doesn't move for a second or two it enters into a fine- adjustment mode. * Gkt::ProgressBar coupled with Gtk::Spinbutton: CSS can get this looking pretty good but some extra work has to be done as the ProgressBar doesn't have an "adjustment", the class that actually handles tracking a value. The Gtk::Spinbutton actually contains a ProgressBar but while one can style it via CSS one can't directly access it and it overlaps the numerical entry part of the SpinButton (this is how the Gimp widget works). * Subclassed Gtk::Spinbutton: This is essentially a modified version of the Gimp widget but it has some major flaws as one cannot access the underlying widgets (ProgressBar, Buttons). In this example, the built in ProgressBar is disabled and new code that simulates a narrower ProgressBar has been added. I could not fine a good way to calculate how much narrower the new bar needs to be to not overlap the numerical entry part. Also, when dragging the bar it is easy to highlight the numerical text. The code to do all this is pretty messy. * Gtk::Scale coupled with Gtk::Spinbutton: CSS can make this look reasonable. Reducing the size of the circle will prevent it from covering text (text not implemented yet). Gtk::Scale also has a fine-adjustment mode accessed the same was as for a scrollbar. Tav

Stickers are here! ... now what?
by C R 12 Dec '17

12 Dec '17

The stickers arrived today. They are of acceptable quality, but I think 300dpi is a little low quality for stickers this small. Also I think the cutting machine had some ink residue, because the border of stickers are a bit dirty on the cut. So, who wants/needs stickers? I have a request for a sheet of the coffee and sheet of the ice cream already. Did we have any solid plans for these yet? See attached for samples.
