RSVP: Inkscape Hackfest, Portland Oregon Apr 28 - May 3, 2017
by Bryce Harrington 12 Mar '17

12 Mar '17

You're invited! We will be hosting a hackfest in Portland Oregon this spring for 5 nights. Tell me ASAP if you might be interested in joining us. We're trying something a bit different for this hackfest. We're renting a house that's been set up for business meetings, with a front unit and a rear unit. We've reserved one unit, and if enough people will be coming we'll grab the other as well. The event will focus on stabilization of the 0.93 branch and infrastructure development. Depending on attendance, we'll also do planning of fundraising activities and brainstorming of outreach efforts. I will send further information soon (the Board is currently voting on a few details), but for now please drop me an email if you might be able to participate. Bryce

GSoC 2017 project idea 5 - Better data structure for selections
by Minglangjun Li 12 Mar '17

12 Mar '17

Hi all, I'm a student and I'm going to apply for GSoC this year. I'm interested in the project idea [1] about selections. But after a quick look at the code of class ObjectSet I found that ObjectSet has already been implemented using Boost::multi_index_container. So is the information on the wiki up-to-date?

Specify interpreter's version for Python extensions
by Minglangjun Li 09 Mar '17

09 Mar '17

Hi all, Today many distros make Python 3 as a default. While some existing Inkscape python extensions are not Python 3 compatible (or vice versa). So maybe I think its better to encourage extension developers to write code that support both Python 2 and 3 at somewhere on the website or wiki. For those existing scripts, we can either use 2to3 to make them compatible or extend our support of Python interpreter to both Python2 and Python3 (currently only "python" is supported in INX files). I prefer the former way, though. What do you think? Regards, Minglangjun

Trying to improve the performance of dragging objects in complex documents
by Minglangjun Li 08 Mar '17

08 Mar '17

Hi all, I notice that dragging objects in Inkscape becomes slow when the document contains a lot of objects. And there's already a bug report (#1198317 <https://bugs.launchpad.net/inkscape/+bug/1198317>) complains about it. It remains unresolved, though. I love Inkscape so I am willing to contribute. The big problem is Inkscape's codebase is too large for me. Currently I only find the following lines which may potentially be optimized (haven't tested). === modified file 'src/seltrans.cpp' --- src/seltrans.cpp 2016-10-24 22:58:43 +0000 +++ src/seltrans.cpp 2017-03-07 15:07:24 +0000 @@ -280,9 +280,13 @@ // (The special points are the handles, center, rotation axis, font baseline, ends of spiral, etc.) // First, determine the bounding box - _bbox = selection->bounds(_snap_bbox_type); _visual_bbox = selection->visualBounds(); // Used for correctly scaling the strokewidth _geometric_bbox = selection->geometricBounds(); + if (_snap_bbox_type == SPItem::VISUAL_BBOX) { + _bbox = _visual_bbox; + } else { + _bbox = _geometric_bbox; + } _point = p; if (_geometric_bbox) { In the previous mentioned bug report they said that the performance dropping has something to do with the bounding box computation. I don't get it. For simple shapes like circles, how can we compute their bbox. more efficiently? Another question is why should we compute the bbox. of the background objects when we drag an object? I think it's the real source of the performance issue. Am I right? Any help is appreciated. Thanks. Regards, Minglangjun

Question for extension development
by Lukáš Haberzettl 08 Mar '17

08 Mar '17

Hello, I have a question about Inkscape extensions UI options. I need textarea input (not only one line for text input, but something like textarea html element), but as far as I studied the documentation I haven’t find out how to do this. Is there any option how to add this type of input to interface of extension? Original of my question can be seen here : https://answers.launchpad.net/inkscape/+question/470626 <https://answers.launchpad.net/inkscape/+question/470626> Thank you for your reply, Lukas Haberzettl

Inkscape Advocates organizational meeting ~ Fri Mar 10th
by Bryce Harrington 07 Mar '17

07 Mar '17

Would you like to contribute to Inkscape by helping spread the word about it? Whether you're new to Inkscape or an old hand, we'll be getting together on IRC to chat about ideas for promoting Inkscape to other communities and to the world at large, and we would love to have you there! This advocacy meet-up will be next week on Friday, March 10 in the #inkscape-devel IRC channel and will kick off around noon Pacific time. Our aim is to establish a new regular team in the Inkscape community chartered to undertake outreach efforts, write and distribute marketing materials, and/or announce our releases. Training classes, merchandise, tradeshows, social media actions, press releases, and more are all possibilities on the table. Exactly what we do will be decided by the group itself, so if you have opinions come share them. Date: Friday, March 10 Time: Noon Pacific Place: irc://irc.freenode.org/#inkscape-devel If you've not used IRC before, you'll need an IRC program for your platform (tons are available), or you can use Inkscape's web IRC portal here: https://inkscape.org/en/community/discussion/ Thanks, and hope to hear your ideas come Friday!

Very early start on the future CAD feature of Inkscape
by Miguel Lopez 07 Mar '17

07 Mar '17

Hello guys, there is a idea that I have in mind which can be considered the very first start to CAD support of Inkscape. When I have manipulated the display units, I noticed that scale x, and scale y does change. I tried to find out what works best from Inkscape to Solidworks .dxf import, and as it turns out, the scale must be exactly 1.0 x and 1.0 y in order to achieve the correct size within Solidworks. The viable workaround to this is of course to make CAD templates, and I might make series of CAD templates. For people who are using Inkscape due to its .dxf support, they have to pay attention to the scale feature with document property. Also, sometimes they have to snap created object within the 0,0 of the workspace in order to import a vector object exactly as if the origin is the rotation point of the object. Modifying the centerpoint can be done with Solidworks, but it's a little tedious, but it can easily be done in Inkscape. There are 4 solutions I can think of for this when it comes to .dxf export, and CAD program support - Under Scale Box, there should be a checkmark which says retain 1:1 scaling when changing display unit. - If I were to export .dxf and the scale factor is not 1, then during the export process, Inkscape should automatically scale the result to 1/x where x represent the scale factor within Inkscape. Also, I wouldn't support px export in .dxf. - There should be a option to display the axis line within document property. That means the X line or horizontal line and the Y line or the height line. - Last of all, under .dxf export, I think one should have the option to always export the name of the unit being used next to the file name. That way, it would be easy to tell what's being used to avoid scaling issues within .dxf. Right now, all I have are templates, and I might try to give them out to you guys to put on the next release. I will try to talk more about this in the inkscape-devel if I can. Oh, and to Bryan or whatever the name is, I'm not in that state. I'm a university student with a very long commute and possibly suffering from unrecoverable chronic fatigue. It's unlikely I'll ever be able to go to a physical meeting as much as I want to.

Dear Developers, We've just finalised our revised sponsorship details. I've written a rough draft in situ to describe the different levels. https://inkscape.org/en/support-us/sponsors/?edit Please review the right side panel text, it's very rough draft so it'll need some corrections. You can edit it directly, but please don't publish yet. Bryce needs to confirm the details. Best Regards, Martin Owens
