LPE Powerstroke
by Johan Engelen 05 Sep '14

05 Sep '14

Hi all, Release is getting closer, and we need to decide what parts of Powerstroke we are going to release. After release, it will be very annoying for users if we change the output of Powerstroke for certain input parameters. So we have to avoid having to do that. Ideas: - remove reflection-based extrapolated miters (my original extrapolation), add the arc extrapolation miter - remove CubicBezierFit and CubicBezierJohan interpolators, add Catmull-Rom interpolator thanks for input. I hope to work on this soon. -Johan

I have committed the change that enables Extrapolated Arc (used to be only available with specialized build) and removes Extrapolated (mirroring) from the UI. The code to deal with the old extrapolation setting still works, for people that use it in their files. I am not sure if we should keep that code around or not. It won't hurt too much for now, but may become a maintenance burden. (and I don't like having such undocumented features) The arc extrapolation definitely has issues, and needs to be improved (I feel). cheers, Johan

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
