Points can be selected in groups which can be transformed (scale, shear, rotate, translate etc.). Simple orthogonal routing and straight routing work.

Now I cannot compile connector-context.cpp. (It compiled under Fedora 18 I think.)

I am not going to have time to investigate further until I get back from vacation after next week. Tav

Solving bug #166371 - SAX parser
by Krzysztof Kosiński 21 Aug '13

21 Aug '13

Hello After fixing the XXE vulnerability, Inkscape can no longer read SVGs that use entities in URLs. Notable cases include SVGs saved from Adobe Illustrator. There does not seem to be a way to replace these entities without reintroducing the XXE vulnerability. https://bugs.launchpad.net/inkscape/+bug/166371 I just wanted to point out that the best way to solve this would be to use libxml2's SAX parser or the newer XmlTextReader parser to directly construct the tree of Inkscape::XML::Node's, instead of postprocessing the XML tree obtained from the DOM-like parser. With this approach, we could intelligently substitute only string entities and ignore entities that point to URLs or external files. An additional bonus would be a reduction in memory use and load time, since the libxml2 DOM tree would not be created. http://www.xmlsoft.org/xmlreader.html Regards, Krzysztof

Hello, I would like an account on the Inkscape wiki. I’ve been learning how to write extensions, and would like to expand the information available. Right now, I’d like to add screenshots of the different types of INX parameters. Thank you, Drini

EMF import on Linux
by Krzysztof Kosiński 21 Aug '13

21 Aug '13

Hello I know that there is working EMF import on Linux, and you can paste things from e.g. ChemDraw. Is it possible to make this code also work on Linux, using e.g. libemf, or would it require writing a completely new input filter? Regards, Krzysztof

Quoting Josh Andler <scislac@...400...>: > If it's already in use in 2geom and liked, I'd vote for it just > because of that alone. > > Cheers, > Josh Yes, Google Test and Boost Test are close enough that the use by 2geom might be a strong deciding factor. To summarize some of the differences: Google Test: * does not use exceptions. Among other things this means that if a function is called that might result in a test failing, the calling test will need to add an extra line to check status afterwards. * intended to be copied into the using project's source tree * needs the additional 'Google Mock' library for certain things such as comparing collections Boost Test: * uses exceptions to terminate tests * use is with pre-built libs/source that are not copied in-tree (which is an external dependency on that Boost library) * does not have an academic/artificial distinction between 'Mock' objects and general fakes/stubs So as long as it looks good to switch to Google Test, I'd suggest copying in Google Mock to our source, since it is a superset and contains a copy of the full Google Test sources. We should keep the actual gmock use to a minimum (even Google themselves warn against Mock overuse), but the collections support alone is extremely useful.

[Tracing] Kopf-Lischinski compatibility
by Vinícius dos Santos Oliveira 20 Aug '13

20 Aug '13

I reallized that something (T-junction heuristic) I thought it was the home of the bug was a false assumption. The bug was in the customized (will be replaced by lib2geom) printing function. Moving on, I initiated a poll on my blog about a matter that will impact any user of this (libdepixelize) project, with its accompanying information: http://vinipsmaker.wordpress.com/2013/08/20/should-i-really-target-kopf-lis… I'll sleep a bit and back to coding when I wake up. See ya. -- Vinícius dos Santos Oliveira https://about.me/vinipsmaker

Re: [Inkscape-devel] Inkscape Website: Remaining webpage edits
by Jared Meidal 18 Aug '13

Here are some remaining edits I see on the staging website: * Community -Like the Develop parent page this need intro content to the Learn pages to welcome guest engagement * About>>Overview -I dropped some content here. I really needs reworking to form a cohesive voice. If we can formulate a vision for who the readers may be and what resources we want to highlight I think that would help. * Learn -Like the Develop parent page this need intro content to the Learn pages to welcome guest engagement * Learn>>FAQ -I cleaned up some HTML table code and added a few new items here, and need to query out here: do we want to keep the table of contents numbering system? There is a lot of legacy HTML tags associated with this content which was copied over. If this is an organization we want to maintain I can peek in further and try to keep things clean. * Screenshots - do we want this to be a gallery of entire-screen shots showing various work processes at various stages, or a highlight of latest features ordered by release versions (like the existing website), or focus on showcased types of media which can be created (such as the existing Showcase webpage http://inkscape.org/showcase/index.php?lang=en) ?? I've added a few notes in the blueprints of the pages to maintain a list of references content is being pulled from and for vision of the pages: https://blueprints.launchpad.net/inkscape-web Finally some of the "Banner Features" on the homepage require linking and content right? Such as the Features, Gallery and Learning Resources. Sorry if this perhaps addresses too many areas at once. --Jared

Inkscape Website: Translation Instructions
by Martin Owens 18 Aug '13

18 Aug '13

Hey Devs and Users, I've updated the wiki explaining the new Inkscape website's translation instructions. New translations have accidentally overwritten the English content in some places (especially the front page) so to avoid this I've put together a brief explanation of why the front page is hard to edit. http://wiki.inkscape.org/wiki/index.php/WebSite#Translations Please do copy plugins into your local language instead of editing the English versions. All editors are reminded that each language can have different plugins for the same content-location if they wish. Website: http://staging.inkscape.org If you don't have an account and would like to help get content ready, login and send me an email so I can enable staff privileges for you and have you editing the CMS. Happy Editing, Martin Owens

removing overlapping lines
by Andrew Baxter 17 Aug '13

17 Aug '13

Hi, I have an SVG file which I want to burn using a laser cutter, and I was hoping to use inkscape to remove the overlapping line segments which are causing a problem with the laser cutter. (Where two lines in different shapes overlap, the line is cut once for each shape, leaving a heavier line). See here for details of my project: http://blog.highfellow.org/?p=37 There is already an inkscape plugin for removing double lines, but it's not working for the complex shapes in this file. (Inkscape crashes). See this forum post for the plugin: http://www.inkscapeforum.com/viewtopic.php?f=5&t=9578 . I was thinking of trying to fix or rewrite the plugin, but could do with some help getting started. The plugin is implemented as a filter in python, using this inx file: <inkscape-extension> <_name>Remove redundant edges</_name> <id>org.novalis.filter.removeredundant</id> <dependency type="executable" location="extensions">removeredundant.py</dependency> <dependency type="executable" location="extensions">inkex.py</dependency> <effect> <object-type>path</object-type> <effects-menu> <submenu _name="Modify Path"/> </effects-menu> </effect> <script> <command reldir="extensions" interpreter="python">removeredundant.py</command> </script> </inkscape-extension> I was thinking it might work better to implement the plugin as a python language binding extension, rather than as a filter, so that I can use functions and methods from the native inkscape API. One question is where I would start doing it this way; another specific question is whether inkscape has a 'is point on line/curve', or 'nearest point on line/curve' function built in? If so, this would save me a lot of hassle trying to write one. Thanks, andrew baxter
