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

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

I fixed the problems with holes in libdepixelize algorithm. Now the only blocker before work on B-Splines optimization is fix the position of T-junction nodes. I small video of the "polygon with holes": https://vimeo.com/72611259 And a small post describing the last algorithmic changes: http://vinipsmaker.wordpress.com/2013/08/13/splines-extraction-on-kopf-lisc… -- 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

[CAD] Status
by Sebastian Götte 17 Aug '13

Hi, This week I mainly squashed some bugs. The current code [0] still requires -std=c++11 in the CXXFLAGS. Connector creation is working properly now, without stray points left over afterwards. Points can be selected in groups which can be transformed (scale, shear, rotate, translate etc.). Simple orthogonal routing and straight routing work. Libavoid routing works as far as there are no objects to be avoided (I did not yet test it with objects to be avoided). Multiple connectors can be connected to the same endpoint. Remaining problems are: * When moving a connector in selection mode ([F1]), sometimes a stray point appears somewhere inside the bounding box of the original connector (strange one!). * Connector aborting does not work yet. I deactivated these 10 lines for now. * There are some open UI questions: - How to disconnect connectors? - How to re-connect connectors to different endpoints? - How to edit SPPoints as parts of groups? How to move them into groups? - Probably some more which I forgot * Libavoid routing is still untested. * Sporadically, I manage to get the UI into some infinite recursion. I am looking into these issues. Best regards, Sebastian [0] https://code.launchpad.net/~h-e-6/inkscape/connector-wip

[CAD] Comments and SVG Connector proposal
by Tavmjong Bah 16 Aug '13

16 Aug '13

Sebastian, Good to see you're making some progress squashing bugs. I've played around a little bit with the code. Here are a few observations: 1. Points (ports) need to be shown on the screen independent of whether or not they are attached to connectors. 2. Creating a connector should use a pre-existing point (port) if the cursor is near a point at the start or create a new point if it is not. The same thing should happen for the end point. 3. A distinction needs to be made between dragging a freely movable start/end point and moving a connector end from one port to another. 4. In your current code, drawing a simple connector creates a start point and an end point at the beginning of creating a connector. At the end, a new end point is created but doesn't seem to be actually used. 5. There needs to be one final redraw at the end of creating a connector. Since getting something out of Doug is like pulling teeth, I've put together a page on what I envision SVG 2 connectors to look like.[1] The key point (no pun intended) is that connection points can be defined using percentage values related to the objects they are part of or to the connector end points themselves. The one problem I have is how to specify a connection point inside a <symbol>. I hope to discuss this at the next SVG Working Group meeting. Your feedback (or anybody else's feedback) is welcome.
