Adding multiple knot holders to the same LPE effect
by Papoj Thamjaroenporn 06 May '14

06 May '14

Dear Inkscape-devel, I am trying to figure out what the best way to add multiple user-defined knot holders to the LPE is. Let’s say I want to allow lpe-tangent_to_curve to have multiple tangent knots that I can slide independently, or lpe-knot to have multiple independent knots instead of shifting between each intersection by dragging a single knot around. What is the best practice of doing this? The mechanism of implementing addKnotHolderEntities(), knot_set(), knot_get() seems to support the case that I have just one knot to insert (per class defined). I am not sure if it can support multiple knots (of the same kind) that work independently from each other this way. Another related question is, what’s is best practice to store multiple ScalarParam’s or VectorParam's that basically do the same thing? Again, let’s say I want to implement lpe-tangent_to_curve so that I can look at multiple tangent lines independently. Would you use, let’s say, std::vector<VectorParam> or ArrayParam<VectorParam>? If someone can point me to existing LPE code that does something similar I’d also appreciate, since I haven’t found it so far.

illustrator plugins?
by mathog 05 May '14

05 May '14

Has anybody ever looked into what it would take to make Illustrator plugins work in Inkscape? Presumably there is some sort of Illustrator plugin API, and depending on what it does, it might be possible to build a compatible API into Inkscape. Regards, David Mathog mathog@...1176...

Experimental feature enabling
by Josh Andler 05 May '14

05 May '14

Hey all, Mainly because I got tired of having to modify multiple files if I ever do a "bzr revert", I just went ahead and simplified a couple other places we had experimental stuff in addition to Tavmjong's. The LPE Tool (Geometric Tool/Technical Tool... I don't recall the outward facing name) and all "test" or experimental LPEs can now be enabled in configure.ac by uncommenting line 110. This has replaced enabling these in toolbox.cpp and effect.cpp respectively. Yes, I could have added a mega "enable everything" line, but keeping the SVG2 stuff and LPE stuff separated seemed reasonable enough. Hopefully it makes it a little easier for others too... Cheers, Josh

help on fillet LPE
by Jabiertxo Arraiza Cenoz 04 May '14

04 May '14

Hi to all, im developing a filleting LPE tool [1]. For the moment and based in the work in powerstroke i have a LPE that: * Create a Knot for each cusp node, with movement restricted to a curve. * Update Knots at path change/add/sustract/reverse/append/erase Any body can point me about the usage of arcTo from Geom::Path? The points i know are: start of arc, and end of arc, and think allways is 180ª arc. Other points/values need to be calculated. I have something in my mind but i want to have a expertice opinion. Thanks for our time reading, Jabier. [1] https://code.launchpad.net/~jabiertxof/inkscape/fillet

New SVG compliance testing software
by Tomasz Boczkowski 02 May '14

02 May '14

Hi! I have extended current software for running SVG compatipility test suite. Now it supports storing and reviewing test results by a web application. Test results for revision 13330 are available online at http://tboczkowski.linuxpl.info/svg_compliance/compliance/trunk. The general idea is to store the test results for selected revisions at server. There they can be reviewed manually. If result images of a test case are equal, they share the same mark. Client-side code [1] is based on Guiu Rocafort's solution. I added a module that packs the output directory, adds some metadata and sends them to server. Instead of provided input files, I use vanilla W3C test cases from [2]. Server-side application [3] is implemented as Django project. It stores information about test cases, test results and image marks in database. Tests results can be browsed and reviewed by web interface. Changing image mark is available for logged-in users only. To aid in reviewing images, I used image comparison functions from resemble.js library. When inkscape generated image is first clicked, it is replaced by raw difference with reference image. Second click switches to a diff ignoring antialiasing. Third click returns to original image. The next step will be to implement the generation of reference image library at server. It would consist of known passes and known fails. When a local testsuite will be run, client will download up-to-date library and compare test results to reference images. It can also calculate regressions and new passes since the latest revision stored at server. I have noticed that test results are greatly influenced by used fonts (e.g [4]). Since the test fonts are supplied with W3C test suite, it would be nice to use them. Does Inkscape support SVG and Woff fonts? If so, is there a command line switch or environment variable allowing to select the font directory? Do you think it would be sensible to add such option? I haven't yet rated the images. I'll do it over the weekend. Regards, Tomasz

Try recompiling the build tool with this line: g++ buildtool.cpp -o btool -fopenmp rebuild, and see if it now works.

Website Request: LPE News
by Martin Owens 29 Apr '14

29 Apr '14

Hi Devs, I've noticed there's quite a few LPE features going in, and it would be nice if we had a news article in the next few weeks that detailed them, their experimental or not status and any extra information. I'll do it as a fallback, but an LPE dev would be best to do a write-up. (send me any details if you think I should) I know there's been power stroke changes, there's the ponyscape LPEs on the horizon as well as Jabiertxof's Simplify and Perspective Envelope additions which are very useful. Anything else? Any other thoughts? Best Regards, Martin Owens
