It's likely quite a forgotten thing, but filters as they stand, do contain a crude method along these lines. If you go into settings, you can drop the filters rendering quality, which will limit the rendering resolution when editing. You will get quite notable artifacts, but it's vastly faster in many cases. There are a couple quality settings available in the filtering code. It could be useful to look into those and see if there's some better default combination than what we have now.

Large filter areas
by Diederik van Lierop 08 Jul '14

08 Jul '14

Hi ppl, It's no surprise that filters can make Inkscape crawl, and I ran into that while digging into this bug https://bugs.launchpad.net/inkscape/+bug/827192 In this case though, the area to be filtered measures 18416 x 17524 pixels, which is a bit too much for just on screen display. Is there any way to work around this? Can't we set an upper limit on the area, in order to keep Inkscape somewhat responsive? If it takes a few seconds that's OK IMHO in such extreme cases, but at least the user should be able to trust that Inkscape will recover. Diederik

requesting wiki account
by Brynn 06 Jul '14

06 Jul '14

Hi Friends, I've been given edit privileges at inkscape.org from Martin Owens. I want to re-organize and edit some of the community info, including Inkscape forums, tutorials and galleries. I came across info about forums, tutorials and galleries in the "old" wiki, and wanted to know about incorporating it into the new inkscape.org. He suggested that forums, tutorials and galleries probably don't belong in the wiki anyway, and said I should delete them, if I can get access to the wiki. He said the wiki (an updated and current wiki) should only contain development, design, code, etc., anyway. (Also told me to email this mailing list to ask for a wiki account.) So assuming you all are in agreement with him, I'm asking for access to be able to edit the wiki. I'll be glad to do any tedious, menial work that might need to be done there, to bring it up to meet the current needs of the community -- if anyone can tell me what kind of work that would be. Should I get access to the wiki, I would be at your disposal. Maybe most of you probably don't know me, but I've been a moderator at InkscapeForum.com for a few years, and nearly a year ago, opened a new Inkscape website (http://forum.inkscapecommunity.com/index.php). So I'm fairly well connected to the user community....at least those who post in forums. Thank you very much, brynn

Re: [Inkscape-devel] Inkscape-devel Digest, Vol 98, Issue 4
by Jelle Mulder 06 Jul '14

Ehm,.. not Inkscape related really, but I am looking for a C++ programmer to earn a few thousand euro's with a probably fairly easy task. (my estimate is a week part-time). I thought someone here might be interested and it would sort of indirectly help the project as well by supporting my favourite programmers. I hope not with a weeks delay though, don't want to interrupt what's going on here. If interested, send me your rating fee and we'll pick it up from there. There is some time pressure on it, so if you don't have time the coming few weeks, state it clearly in your e-mail. I may have other tasks later for the same or other clients as well. Cheers, Jelle

GSoC Project Update
by Krzysztof Kosiński 06 Jul '14

06 Jul '14

Hello The midterm evaluations are near due, so here's a public update on my GSoC project. The schedule this year was very bad for me, and dealing with university stuff ate most of my time in the first half of the project, so I didn't do nearly as much as I hoped for. I have however made a prototype CGAL-based implementation of boolops. It is available in 2Geom trunk; you have to have CGAL installed, its headers available in your default include path, and set the CMake option CGAL_TOYS=ON to compile it. Saying "sudo apt-get install libcgal-dev" suffices to satisfy the first two requirements on Ubuntu 14.04. The results of playing with this toy are rather disappointing. CGAL produces visibly imprecise results even for simple shapes (see attached pictures), and for some inputs (e.g. when sliding two bananas over each other so that they nearly match) it crashes with an assertion. It seems that its boolean operation algorithm for Beziers is of very poor quality. This means I will have to write the boolops code from scratch. I've found a MIT-licensed Objective-C library that implements boolops on Bezier paths, which may serve as an inspiration. https://bitbucket.org/andyfinnell/vectorboolean During the remaining time before midterm, I'll work on path-related APIs in 2Geom. This will be useful when implementing boolops, and will allow us to get rid of ugly ancient stuff in Inkscape, such as SPCurve. After the midterm, I will have to complete a final assignment at the university, and should have much more time to get useful work done in the second half of the project. Regards, Krzysztof

Bug of the Week - 167834
by Bryce Harrington 02 Jul '14

02 Jul '14

David is selecting bug #167834 as one of the two bugs of the week for this coming week. Please take a quick look and see if you can help move it to solution by Monday; it already has a verified patch that just needs wider testing. This is an ancient bug and so will be worth a ton of points for us. """ This one: https://bugs.launchpad.net/inkscape/+bug/167834 I am not sure exactly what the original problem was, but the examples in posts 4 and 5 are not visible in Inkscape (on XP). Maybe that was the problem?

Threading problem in extension system
by Johan Engelen 02 Jul '14

02 Jul '14

Hi all, There is a threading problem with the extension system. It results in a crash when saving a document and quitting while the save is happening. Have a look here: https://bugs.launchpad.net/inkscape/+bug/967416 I don't know enough about glib's threading to fix this bug. I do not fully understand where the execution flow is going after the fork (/src/extension/implementation/script.cpp, line 1017, _main_loop->run();), nor where the fork is terminated. I hope someone who knows more about this can have a look. I'm afraid it may lead to pretty weird bugs when running time consuming extensions and doing stuff meanwhile. (gdb reports illegal mem accesses when doing stuff while an extension is running, for example). Is this asynchronous extension execution so important, or can we disable it for now to improve stability? regards, Johan
