Increasing Boost version for py2geom
by unknown＠example.com 19 Feb '10

19 Feb '10

Hello all, While trying to build py2geom, I run into problems because the version of Boost that we use (1.34) does not support our compiler's version (gcc 4.4.1). Not being able to build py2geom is not a huge problem for Inkscape, but it is a big disappointment. I read that Boost 1.37+ does support gcc 4.4.0. Boost 1.34 was released in 2007. Boost 1.37 at the end of 2008. Is that too recent for us to be able to use it? Increasing the version of Boost for Windows is not a big problem, since we have our devlibs. For Linux, I do not know the issues involved. Thanks, Johan

py2geom -- libboost_python binaries in the devlibs
by unknown＠example.com 18 Feb '10

18 Feb '10

Hi all, Now that we moved our devlibs to bazaar, I have write access to it and could upload the boost binaries required for building py2geom on Windows. I've added details on how to build it on our Wiki. Hope this helps spread the use of py2geom! Ciao, Johan

Hello, just wanted to ask if new development version will be available for testing on http://inkscape.modevia.com/win32/?M=D . It seems that no new devel builds have appeared there for quite some time. Thanks, Mourad

Node tool crash due to modified path data?
by ~suv 18 Feb '10

18 Feb '10

Trying to node-edit the third path in the attached file immediately and reproducibly crashes inkscape (tested with Inkscape 0.47+devel r9092 on OS X 10.5.8). - The path was created by combining two copies of a rectangle and applying (testing) the proposed extension 'Remove redundant edges' from recent launchpad report #521988 <https://bugs.launchpad.net/inkscape/+bug/521988> - The path is rendered without error in Squiggle (Batik 1.7) - The path can be node-edited in Inkscape 0.47 r22583 without crash. I don't know what is wrong with this specific path but even if the path data is invalid wouldn't it be better if Inkscape displayed an error message and refused to render or edit it? ~suv Process: inkscape-bin [8471] Path: /Volumes/blue/src/Inkscape/Inkscape-BZR/Inkscape.app/Contents/Resources/bin/inkscape-bin Identifier: inkscape-bin Version: ???

Problem with POpen on windows
by Rob Antonishen 17 Feb '10

17 Feb '10

Hi- I discovered the restack extension stopped working (under windows at any rate) in .47 for more than 82 objects in the svg document The code calling inkscape with the --query-all parameter (to get all the bounding boxes) was: if bsubprocess: p = Popen('inkscape --query-all "%s"' % (file), shell=True, stdout=PIPE, stderr=PIPE) rc = p.wait() f = p.stdout err = p.stderr It will just hang the python window in such a case. I found my removing the rc = p.wait() line the extension will work... but I am not sure of the impact of making that change. I see the Popen.wait call is used in other extensions as well, but they all seem to be using the single object query flag --query-id=ID, so so not experience this problem. The python docs state Popen.wait "will deadlock if the child process generates enough output to a stdout or stderr pipe such that it blocks waiting for the OS pipe buffer to accept more data. Use communicate() to avoid that." but it also states that with communicate() "The data read is buffered in memory, so do not use this method if the data size is large or unlimited." -Rob A>

Inkscape 0.48 Release Progress
by Joshua A. Andler 16 Feb '10

16 Feb '10

Hey All, It appears that everything is still on track for 0.48. Given that, I'd like to remind everyone that Chill will be setting in about 2 weeks from now. For those that do not know, here's what happens during Chill: New feature development focuses on wrapping up. We identify current 'make distcheck' issues. Have a small sprint to Triage new bug reports. Run an About Screen contest. Ensure that the Release Notes are at First Draft stage. Update tutorials and other docs (we could use volunteers). I'd like to push that if we want to get the DBUS stuff in for this release, that we look to get it merged by the 1st of March if possible (we just need to not break anyone's compilation, we can get it working on all platforms after the fact). Lastly, there is always an "open culture" issue about the hosting of the About Screen contest. Unless someone has something functional and easy for us to use by Chill, it will be taking place via DeviantART again. Any questions or comments? Cheers, Josh

Connecticut Film Festival
by Joseph Annino 15 Feb '10

15 Feb '10

I am a volunteer with the Connecticut Film Festival, Interactive and New Media component. Our festival, in its 6th year, this being the 2nd year of the Interactive and New Media component, is looking for presenters for workshops and panels. The festival is May 4-9, with the Interactive component on May 7,8,9, Friday to Sunday, in Danbury CT, located about 60 miles from New York City. Our theme this year is "Connections Multiplied". We have a strong focus on free and open source software for creative professionals. I think Inkscape would be an excellent fit as an illustration tool. We already have presenters lined up for Blender and Celtx, and representatives from the FSF and EFF. We want this festival to be a way for developers and users of these tools to connect with each other, as well as educate the larger public about their existence, usefulness, and importance. If anyone with extensive user, development, and/or training/presentation experience with Inkscape is interested in being a presenter please contact me at joeaguy@...400... to discuss further. We can provide hotel accommodations, and have limited funds to reimburse travel, so we would prefer someone based in the north east USA if you need travel reimbursement. I would also like to extend an invitation to our conference to all the members of this list. Please feel free to pass on this message to anyone whom might be interested. Our web site is http://ctfilmfest.com

To clarify: you're talking about a path which is NOT closed? Then it sounds logical (although I wonder why Inkscape would add a closing segment). If you're talking about having a closed path and then not adding the closing segment, please reconsider. Inkscape used to do this in the past and it caused some very nasty bugs (having to do with round-tripping for one), apart from simply being incorrect (at least in SVG).
