Gtk+ 3 build bit-rot alert!
by Alex Valavanis 05 Sep '14

05 Sep '14

Hello All, I thought I'd quickly check how we're doing with the Gtk+ 3 build in Ubuntu Utopic, and was unpleasantly surprised to see that: (a) A tonne more symbols that have been deprecated in Gtk+ 3.10 (principally, GtkAction) (b) We have a few regressions, and have resumed use of some deprecated symbols that we had previously replaced. (e.g., GtkHBox) I have updated bug #1016020 with the latest build log (20k lines caused by deprecation warnings!!) and summarised the failures in the description. Obviously, (a) isn't our fault, but we should try to regain the progress we had made! (b) is more of a concern, since we're actually moving backwards! Ultimately, we should really try to enforce "-Werror=deprecated-declarations" in our dev builds, but clearly we're far away from that goal. Would it be reasonable to target a deprecation-free build for Inkscape 1.0? In the meantime, can I please request that from now on, everyone runs a strict build with both Gtk+ 2 and Gtk+ 3 before merging in any new features, so that we can ensure that we're not introducing any new warnings? Thanks, AV [1] https://bugs.launchpad.net/inkscape/+bug/1016020

So we should keep that or perhaps your "Smooth" variant. If we keep the Johan variant, we must give it a different name (in SVG) and so will definitely be incompatible with Ponyscape files that use CubicBezierJohan. (we really can't release with that name in SVG) -Johan

Stroke placement
by Tavmjong Bah 04 Sep '14

04 Sep '14

Hi, We discussed variable placement of stroke (e.g. inside/outside/10% inside,90% outside). The key to implementing this is having a good way to offset a path as then one can use existing rendering libraries to draw the stroke (including things like dashes, line-caps). If I can provide a clear (testable) algorithm for how to offset a path, there is a good chance we can get this into SVG 2. The current Inkscape code for offsetting is a bit buggy. I believe lib2geom has better code. Can anybody comment? Thanks, Tav

need advice on faq item re command line
by Brynn 02 Sep '14

02 Sep '14

Hi Friends, FAQ #3.8.1 contains some garbled text. Unfortunately, I don't know anything about using Inkscape from the command line.....or much about the command line, in the first place. So I'm not sure exactly how to fix it. The current text is below, for convenience. Or here's the URL: http://inkscape.org/en/learn/faq/#Missing_console_output_issue Fyi, I'll be combining this with item #2.20. Could someone either fix the current text, or offer a short re-write for me? It's the first sentence or 2, which need attention. Or if that info is outdated, I need to know the new info. If anyone wants to see what I'm working on: http://staging.inkscape.org/en/brynns-user-faq Comments welcome. Besides updating and re-organizing, I'm taking out a whole bunch of old useless code! (whole bunch!) It's probably about halfway finished, and then I'll start on the faq for developers. Note that I have uploaded some tiny images of icons, in the How-To section, but they have somehow become lost. Martin is on the case ;-) And btw, when I get to work on the Developer FAQ, for the most part, all I'll be able to do, is take out the useless code, and *try* to reorganize the items. Since I'm such a newbie to this world, I won't be able to decide if some need to be deleted, or if some text needs to be updated, or if new items need to be added. That part will have to be up to you guys :-) Text below. Thanks, brynn "As of the 0.48.2 release of the windows installer an inkscape.exe and an inkscape.com. The start menu shortcut points to inkscape.exe which does not write any output to the console. However, if you type inkscape in a command prompt, and the install directory (C:\Program Files (x86)\Inkscape\) is in your path, the command prompt will resolve inkscape.com before inkscape.exe. The file inkscape.com is actually a windows executable, that callsinkscape.exe and attaches it to the console window, therefore displaying stdout and stderr to said console. If you call inkscape.exe from the command prompt, things like exporting or converting to plain SVG do work, they just do not output anything to the console. If you are using an older version of Inkscape, or just wish for historical context, see this mailing list thread."

Alignment in C++ classes
by Liam White 31 Aug '14

31 Aug '14

While browsing through header files in experimental I found these sort of things: sp-object.h unsigned int cloned : 1; unsigned int set : 1; unsigned int value : 1; sp-namedview.h unsigned int editable : 1; unsigned int showguides : 1; unsigned int showborder : 1; unsigned int showpageshadow : 1; These look very much like a holdover from C which did not have a boolean type like C does. Is there any viable reason for not simply converting these to boolean? There are other, similar things that I saw as well (sp-namedview.h): unsigned int borderlayer : 2; and I believe this variable is meant to hold an enum type. Should it just be changed to the type of the enum with no alignment or is there a reason to not do that?

The annoying ghost node bezier tool bug
by Artemis Scheepstra 30 Aug '14

30 Aug '14

I have seen this bug since the older (like, five years old) versions from inkscape: https://www.youtube.com/watch?v=Xn-pbY8Vjiw&feature=youtu.be You start to draw a shape, hit backspace, finish the shape and the deleted point appears again! Is that a feature or a bug? Oscar

0.91 pre2 not yet 100%
by john Culleton 29 Aug '14

29 Aug '14

When fooling around with 0.91.pre2, the latest bzr revision 13529 I had some problems with text objects. Sometimes the text object would become invisible. Sometimes as I attempted to modify the text object I would get a crash. I can't pinpoint the exact circumstance but I will try the same tasks using 48.5 to see if it is a real problem or just my own inexperience. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

should a change in document units be undone by ctrl-Z ?
by alvinpenner 27 Aug '14

27 Aug '14

there is a difference between Inkscape 0.48.5 and current trunk with respect to this issue. In Inkscape 0.48.5 a change in document units is not undone by ctrl-Z. in 0.48.5: - draw object - change document units - hit ctrl-Z, object disappears but the new units are kept - hit ctrl-Z again, nothing happens in trunk, rev 13534: - draw object (preferably not a rectangle) - change document units - hit ctrl-Z, units revert back to original - hit ctrl-Z again, object disappears Personally I prefer the behavior of Inkscape 0.48.5. It seems to me that ctrl-Z should apply only to visible objects, and document units is not a visible object. Apart from that, the current behavior leads to a crash if you use a rectangle, see: https://bugs.launchpad.net/inkscape/+bug/1348382 thoughts?

One more typographic template proposal
by ivan louette 26 Aug '14

26 Aug '14

Hello, Here is a draft for a template proposal adapted to Inkscape Typographic Extension used togheterwith SVG filters to alterate typefaces (some tastes of the Cross-Smooth filter are included in the template and accessible by the Filters Editor). I apply one of the filters to the charater visible in the window, then I fill the result with the "Fill bounded areas" tool and Then I do Extensions/Typography/Add Glyph Layer. One of my problems is that I don't know how I could precisely place the text origin to zero in this template. I did it manually (and it gives good results when opening the SVG font in FontForge) but I would do it more exactly. I don't figure how I could do it with the XML Editor. Another problem is that the range of unicode characters useable to type into the "Add Glyph Layer" dialog box isn't very wide (for example accented characters doesn't work... and Iuse french language). Could it be possible to fix that ? But a funny facility in this dialog box is that you can type a lot of characters at one time in this dialog box and then it creates one layer by character ! Enjoy ! ivan
