Inkscape meeting at Libre Grapics Meeting
by Jon Cruz 11 May '11

11 May '11

I just wanted to drop a quick note that the Libre Graphics Meeting has scheduled a general Inkscape team meeting for today at noon (two hours from now). To try to be inclusive (especially since not many Inkscape contributors made it to Montreal this time) I'll be on IRC throughout the meeting and try to bridge some of the questions and conversation. I would encourage any who are able to get on our IRC room and ask as well as answer questions, goals, etc. Thanks.

Complie error

Hi, Just tried to compile Inkscape trunk on my spanking new laptop (replacing my 6.5 year old one). It failed in 2geom with an error from the boost library. I used Fedora 15 beta which has boost 1.46 and gcc 4.6. The error message is: In file included from 2geom/transforms.cpp:37:0: ./2geom/transforms.h: In member function ‘S& Geom::ShearBase<S>::operator*=(const S&) [with S = Geom::HShear]’: ./2geom/transforms.h:59:9: instantiated from ‘void Geom::TransformConcept<T>::constraints() [with T = Geom::HShear]’ /usr/include/boost/concept/detail/has_constraints.hpp:42:98: instantiated from ‘const bool boost::concepts::not_satisfied<Geom::TransformConcept<Geom::HShear> >::value’ /usr/include/boost/concept/detail/has_constraints.hpp:45:31: instantiated from ‘boost::concepts::not_satisfied<Geom::TransformConcept<Geom::HShear> >’ /usr/include/boost/mpl/if.hpp:67:11: instantiated from ‘boost::mpl::if_<boost::concepts::not_satisfied<Geom::TransformConcept<Geom::HShear> >, boost::concepts::constraint<Geom::TransformConcept<Geom::HShear> >, boost::concepts::requirement<boost::concepts::failed************ Geom::TransformConcept<Geom::HShear>::************> >’ /usr/include/boost/concept/detail/general.hpp:50:8: instantiated from ‘boost::concepts::requirement_<void (*)(Geom::TransformConcept<Geom::HShear>)>’ 2geom/transforms.cpp:121:120: instantiated from here ./2geom/transforms.h:212:77: error: invalid initialization of reference of type ‘Geom::HShear&’ from expression of type ‘const Geom::HShear’ ./2geom/transforms.h: In member function ‘S& Geom::ShearBase<S>::operator*=(const S&) [with S = Geom::VShear]’: ./2geom/transforms.h:59:9: instantiated from ‘void Geom::TransformConcept<T>::constraints() [with T = Geom::VShear]’ /usr/include/boost/concept/detail/has_constraints.hpp:42:98: instantiated from ‘const bool boost::concepts::not_satisfied<Geom::TransformConcept<Geom::VShear> >::value’ /usr/include/boost/concept/detail/has_constraints.hpp:45:31: instantiated from ‘boost::concepts::not_satisfied<Geom::TransformConcept<Geom::VShear> >’ /usr/include/boost/mpl/if.hpp:67:11: instantiated from ‘boost::mpl::if_<boost::concepts::not_satisfied<Geom::TransformConcept<Geom::VShear> >, boost::concepts::constraint<Geom::TransformConcept<Geom::VShear> >, boost::concepts::requirement<boost::concepts::failed************ Geom::TransformConcept<Geom::VShear>::************> >’ /usr/include/boost/concept/detail/general.hpp:50:8: instantiated from ‘boost::concepts::requirement_<void (*)(Geom::TransformConcept<Geom::VShear>)>’ 2geom/transforms.cpp:122:120: instantiated from here ./2geom/transforms.h:212:77: error: invalid initialization of reference of type ‘Geom::VShear&’ from expression of type ‘const Geom::VShear’ ./2geom/transforms.h: In member function ‘S& Geom::ShearBase<S>::operator*=(const S&) [with S = Geom::HShear]’: ./2geom/transforms.h:212:80: warning: control reaches end of non-void function [-Wreturn-type] ./2geom/transforms.h: In member function ‘S& Geom::ShearBase<S>::operator*=(const S&) [with S = Geom::VShear]’: ./2geom/transforms.h:212:80: warning: control reaches end of non-void function [-Wreturn-type] make[3]: *** [2geom/transforms.o] Error 1 Any clues?

Recent surge of spam in the wiki
by ~suv 04 May '11

04 May '11

In recent weeks, Inkscape's Wiki is increasingly targeted by (presumably) spam bots which create a new user and a new page with spam (including uploaded images) [1]. 1) Could the wiki use tighter rules for the creation of new users (captchas?) that can't be exploited as easily as apparently the current configuration? 2) Who does have admin credentials to change the current wiki configuration? 3) Who else does have admin rights to clean up (delete pages, block user accounts)? At the moment, it seems as if 'Legio noctis' is the only one with sufficient admin rights who cares and cleans up from time to time, but if the spam surges as it has in recent days, maybe this clean-up task could be shared by several users, or even done by a script? ~suv [1] <http://wiki.inkscape.org/wiki/index.php?title=Special:RecentChanges&hidebot…>

Gtk3 and libgdl
by Joel Holdsworth 04 May '11

04 May '11

Hi All, I'm interested in upstreaming libgdl so that we can remove it from the inkscape codebase, but I notice that GDL has now been ported to Gtk3. Are there any plans in motion to port inkscape to Gtk3. Or is this something I could consider involving myself with. Best Regards Joel Holdsworth

Upstreaming Inkscape's libcroco
by Joel Holdsworth 01 May '11

01 May '11

Hi Inkscape Devs, I've decided to take it upon myself to try and get Inkscape's libcroco pushed upstream. I've been doing some web searching about the previous discussions that have gone on about it: http://mail.gnome.org/archives/libcroco-list/2007-February/msg00000.html http://mail.gnome.org/archives/libcroco-list/2009-March/msg00001.html https://answers.launchpad.net/inkscape/+question/123799 https://bugs.launchpad.net/debian/+source/inkscape/+bug/648246 https://bugzilla.gnome.org/show_bug.cgi?id=572454 http://bugs.gentoo.org/show_bug.cgi?id=252510 I've been doing some work pulling out the differences between inkscape and upstream crocco into a series of tidy patches. The main differences are the libxml split-out, fixes for compiler warnings, and a couple of minor bug fixes. But as you know the main issue is about splitting out libxml, and I see that this has already been attempted here:http://bugzilla-attachments.gnome.org/attachment.cgi?id=129078 Do anyone know anything about the status of this patch? Was is rejected for some reason? Best Regards Joel Holdsworth

Hi Guys, So I have been doing a lot of work on the Gallery dialog (the OCAL dialog is still in progress ;] ) and I have finished! Again I was wondering whether I could get some testing, especially on some different platforms. You will find the dialog in File > Gallery Thanks!

Curve sketching--Cornucopia
by Ilya Baran 25 Apr '11

25 Apr '11

Hi, A while ago I asked the Inkscape list whether there was interest in an implementation of my curve sketching algorithm (see the thread at http://sourceforge.net/mailarchive/message.php?msg_id=24902605). There seemed to be interest and I wrote a cleaner (and much faster) version, although this took longer than I anticipated. There are still a bunch of improvements possible, but at this point it's quite usable. The code and a windows installer for a demo binary are available at http://code.google.com/p/cornucopia-lib/ and there's some documentation. I am completely unfamiliar with Inkscape's codebase, so the integration would need to be done by one of the Inkscape devs. As a proof-of-concept, however, I wrote a very crude replacement of the bezier_fit_cubic_r call with a call to Cornucopia in the pencil tool (patch attached--of course, you have to build and link to Cornucopia to try it). For the real thing, I'd need to find a better mapping from the "smoothness" slider in Inkscape to my myriad of parameters. Is someone interested in working on this? I would, of course, help in what way I can (although I'm pretty busy these days and my response latency may be high occasionally). Thanks, -Ilya

My implementation essentially exposes almost every magic constant in every algorithm as a parameter, so there are 30 or so. There are parameters that specify what kinds of primitives (arcs, lines, clothoids) and transitions are preferred, and the rest mostly tradeoff accuracy vs. simplicity and quality vs. performance. For a real UI, therefore, I think that one or two sliders (the quality vs. performance slider is probably optional) and some buttons for choosing the curve type should be sufficient.
