Plugin: onionskin plugin for animation
by Lucas H 28 Apr '14

28 Apr '14

Hi there, I recently wrote a plugin to allow an 'onionskin' view of inkscape layers to aid animation. I'm developing some other animation-related plugins, too. Someone told me I should let the Inkscape dev team know about it, so here I am. All the info is here: http://github.com/lingo/inkscape_onionskin Reddit post (for flames,trolls,or upvotes): http://www.reddit.com/r/Inkscape/comments/242ys3/onionskin_plugin_to_make_a… Kind regards, - Lucas

Units
by Tavmjong Bah 28 Apr '14

28 Apr '14

Hi, I had a discussion with several people at the SVG Working group meeting in Leipzig this past week about user units vs. "real" units. I proposed that it be possible to set a ratio for the initial user unit to inch (or cm). This was not well received. My basic conclusion from these discussions is that the use of any real unit (inch, pt, etc.) inside an SVG file (other than on the root 'width' and 'height') is pointless. The correct way to proceed is to set the 'width' and 'height' of the SVG to the size of the drawing and then the 'viewBox' to the same values without units, e.g.: <svg width="20in" height="15in" viewBox( 0 0 20 15 ) ... > Once you have done this, one user unit is one inch. If you actually set a length to an inch inside the file (i.e. width="1in"), it will be interpreted as 90 inches since we use 90 user units per inch. OK, so be it. The gods have spoken. However, we should at some point change 90 user units per inch to the CSS 2.1 value of 96 which has now been fixed in stone. (Illustrator has the same problem, having used a value of 84.) Tav

New LPE roughen
by Jabiertxo Arraiza Cenoz 26 Apr '14

26 Apr '14

Thanks to Josh for the idea to port two extensions to a one LPE. The extensions are Add Nodes and Jitter nodes. And the effect born as "roughen". I need some help to redefine the strings to make more easy to undertand. Also can work on widgets to visual make a separator from Add Nodes widgets and Jitter ones. Here are the code: https://code.launchpad.net/~jabiertxof/inkscape/roughen Regards, Jabier.

Merge in certain Ponyscape features
by liamw 25 Apr '14

25 Apr '14

Many of the developers are probably aware of a popular fork of Inkscape called Ponyscape. If you don't know of it, here are the extra features it offers: • Inverse clipping (clearly I'm not going to merge this in) • Objects dialog (http://sta.sh/0zb66ec8hyk ) • Tags dialog (selection sets http://sta.sh/01n137vphezw ) • Power stroke point control dialog (activated by shift+clicking width points http://sta.sh/01s1vyyazw8k ) • CubicBezierSmooth Power Strokes (http://sta.sh/0232eheuvzn0 ) • UI enhancements (for example https://bugs.launchpad.net/inkscape/+bug/1310688 ) • 5 new path effects ◦ Attach Path (there is a great tutorial on this by R4inbowR4ge here http://youtu.be/5o5P0897vb8 ) ◦ Bounding Box (...clearly you know what this one does, right?) ◦ Ellipse by 5 Points ◦ Fill Between Strokes (obsoleted) ◦ Fill Between Many (http://sta.sh/0mze2vk449o ) Path effects gallery: http://sta.sh/2257tq53v5kb My plan is to get (most) of these features merged into trunk to keep them from bit-rotting away. I have created a branch here at Launchpad: https://launchpad.net/~inkscapebrony/inkscape/inkscape which addresses the majority of these features. I've also fixed this: https://bugs.launchpad.net/inkscape/+bug/1290573 and this: https://bugs.launchpad.net/inkscape/+bug/1290573 (AFAIU neither have been fixed in trunk) I'm asking for a little review—and possibly some feedback?—on the new features in the branch. Also, I am not familiar enough with the Inkscape codebase to know what to do with the very old looking SPTag stuff, which is why it isn't in my branch yet. If anyone wants to take a look and advise me on how to refactor this to make it work, the tag stuff is here: http://sta.sh/01etufm3jqvt (seriously, what the heck is an SPObjectClass? is that some sort of impls thing?) -- View this message in context: http://inkscape.13.x6.nabble.com/Merge-in-certain-Ponyscape-features-tp4970… Sent from the Inkscape - Dev mailing list archive at Nabble.com.

Clang address sanitizer abort

Hi, Fedora 20 recently updated from clang 3.3 to clang 3.4. When I compiled Inkscape trunk with the new version and ran it, I immediately got an abort. I was playing around with clang a few months ago and appear to have set the CXXFLAGS to: -fsanitize=address-full,undefined,integer Can anybody help me interpret the error message?

Hi All, We're happy to announce that we have two students who will be working on projects with our organization this year during Summer of Code. Krzysztof Kosiński will work on implementing robust boolean and stroking operations for 2Geom. Tomasz Boczkowski will work on improving Inkscape's support for SVG paints. We look forward to working with them and wish them the best of luck this summer. Cheers, Josh

Should select area for text objects include leading and trailing spaces?
by mathog 22 Apr '14

22 Apr '14

In this bug: https://bugs.launchpad.net/inkscape/+bug/1243401 there is a discussion about whether or not the selectable area for a text object should include leading and trailing spaces. That is, for text objects 1 = " " and 2 = " a b " the old behavior was that the "arrow" or "+A" selection pointers would not detect object 1 at all and would move across the leading and trailing spaces of object 2 without registering a hit. The patch in that bug makes these pointers treat spaces like any other character. People were coming down on both sides of the change and ScislaC suggested moving that discussion here. See posts 20-27 for the discussion so far. Regards, David Mathog mathog@...1176... Manager, Sequence Analysis Facility, Biology Division, Caltech
