Nightly/Testing Builds
by Joshua A. Andler 24 Apr '09

24 Apr '09

Hey All, We seem to be in a bad place with our nightly builds. It would be excellent if we could have a few volunteers step up to produce nightlies (or at least builds from every few days). Anyone who can (or would like to) produce builds for Windows, Linux, and OSX would be making a great contribution to keeping us on track to release 0.47 in the near future. If you are interested, please speak up and we will do what we can to get you producing builds ASAP. For the record, this is how bad the situation is: Win32 - April 18th OSX - March 3rd Linux - nothing from this year (Autopackages are over a year old) So again, if lending some CPU cycles and a little time is all you can do, it is still a LOT for the community. Cheers, Josh

Mitigating color-interpolation-filters problems
by Jasper van de Gronde 24 Apr '09

24 Apr '09

According to the SVG spec filters can be rendered in either the sRGB or the linearRGB color space, the same goes for gradients and alpha compositing). The latter is controlled by the color-interpolation attribute, the former by the color-interpolation-filters attribute. Inkscape does not handle either of these. Unfortunately the default for color-interpolation is sRGB, while the default for color-interpolation-filters is linearRGB... This means that Inkscape's rendering of pretty much any filter is incorrect (how severe this is depends on the filter). And perhaps more importantly, it differs from how other renderers behave. I don't think it's a good idea at this time to truely "solve" this problem. But perhaps we could make sure that new filters created by Inkscape automatically have their color-interpolation-filters attribute set to sRGB? (I have no idea how to do that, so any help is appreciated.) For reference, I created the following bug report: https://bugs.launchpad.net/inkscape/+bug/365073

Call for volunteers (non-programming stuff!)
by Joshua A. Andler 24 Apr '09

24 Apr '09

Hey All, Volunteers needed! Do you want to contribute to Inkscape but don't program? We can still use your help! We need volunteers for the following tasks: Testing SVN/Nightly Build (windows and osx especially) Reviewing and triaging Bug Reports Updating Tutorials & Documentation Reviewing Release Notes for accuracy/completion Writing PR/Announcements for our upcoming release Those are needs we always really have, but, we can always use an extra hand in the lead-up to release. Right now, if we could have a lot of attention put on our bug tracker for confirming bugs, figuring out what has been fixed, tagging things, and just getting it in better shape for the bug hunt, it will make a world of difference to the people trying to fix things. If anyone is interested in participating, please feel free to reply, hop on irc/jabber to discuss, or just jump right to it. :) If you need any information, please do not hesitate to contact me. Cheers, Josh

sketch lpe
by jf barraud 23 Apr '09

23 Apr '09

Hi all, I've unhidden the sketch lpe. I decided to remove the "construction line" feature in this effect (it used to place the tangent lines randomly along the input path). My feeling was that the placement should either be tuned by hand, or guessed from curvature extrema or something... Anyway, I felt it was not good enough as is, and would eventually be worth a separate effect (the issue with independant effect is that you need to apply 2 effects on the *same* source path, which is not possible atm --- but no doubt this will come sooner or later! ;-) Anyone having an opinion about this feature or it's eventual splitting in a separate effect? By the way, my dream is that we could import or mimic Blender's 'node' system into inkscape: the effect editor would be a window within which each effect would be a little box with input and output slots (+ input fields + an eventual small window to show the result of the effect), and you would be free to connect ones with others, defining not only a pipeline, but a full graph with parallel ways, etc... You generally end up with a nice plate of noodles, but it's very powerfull. Notice the same thing could be used for both lpe and filters effects. Cheers, jfb.

Take the bottom-most path that has not been processed yet and compute both differences and the intersection with all processed paths. 2. Determine the opaque fill for all three pieces. 3. Go to 1. Step 1 is "just" some bool ops (making sure no empty paths are created if you want to be fancy). Step 2 is trivial if everything uses solid colors. If gradients are involved it becomes a bit more complex, but either it's a simple matter of some algebra or it is not possible to express the result with a new gradient and you'd still have to fall back to a bitmap.

Win32 snapshots on Modevia broken?
by worms invasion 23 Apr '09

23 Apr '09

Hello, For about 2 weeks now, the size of the Windows builds on Modevia is 38Mb, while the size was 44Mb before. I haven't tried to download/install them, because I think they are probably incomplete? Anyone has information about this? Thanks in advance.

Out of Memory Crash
by Craig Leat 22 Apr '09

22 Apr '09

Hi I'm new here, just compiled r21187 on Ubuntu. I'm getting an "Out of Memory!" error when importing an A2 pdf with a large bitmap. I hope to check it's not something funny with my build before reporting a bug. The pdf file is 112Mb in size. Evince on Ubuntu opens the pdf well, but Abode Reader on Windows struggles. Inkscape shows a preview in the PDF Import Settings, but crashes while doing the actual import. A back trace is attached. I watched the free memory while the import was in progress and noted: With Inkscape running - 1195Mb free RAM PDF Import Settings with preview displayed - 1098Mb free RAM Import proceeds and free RAM drops to 48Mb before spilling to swop. 835Mb of swop is used before the app crashes. Total memory usage in RAM and swop before crashing = 1982Mb. Nearly 2Gb of memory is used to import a 112Mb PDF. Seems to me something is wrong. Any ideas if it's my build at fault? Thanks Craig Ps Imports of smaller PDFs (A4) work well.

Spray Tool is NOT going in 0.47... we can't introduce it so late in this cycle if we want to have a shot at releasing anytime soon. For the record I've been testing it as they've been working on it too, so it's not an excitement issue here. :-) On Apr 22, 2009 3:29 AM, "Alexandre Prokoudine" < alexandre.prokoudine@...400...> wrote: On Wed, Apr 22, 2009 at 1:28 PM, John Cliff wrote: >> +1 for DeviantArt > > +1 from me too > We have decent sized community there that have done well for us in the past, > ... Whatever hosting we pick, what rules do we set this time? What particular new features would we want to have being demoed? We have new modes in Tweak tool. We have new Spray tool that might or might not make it into 0.47 (their deadline is 2 weeks away) We have a hell of new SVG Filters and a bunch of new extensions Ah! We have Spiro :) What else?

Inkscape 0.47 Proposed Release Plan
by Joshua A. Andler 21 Apr '09

21 Apr '09

Hey All, In an effort to honor Bryce's work in this department for previous releases, I've liberally copied & pasted what he wrote last time. :) I know that it looks incredibly ambitious with the dates on there, but it IS doable provided people have the time and desire. I'd be interested to see what would happen if we plan a bug sprint weekend on May 9 & 10. We can have whoever is up for the challenge commit to it and see what we can pull off in two days. The following is based on previous release plans. Let me know if there's anything missing. 1. Open development. (Complete) 2. Chill. Development focuses on wrapping up. (In progress) No further refactoring. Identify 'make distcheck' issues Triage bug reports Run an About Screen contest First draft of Release Notes. Update tutorials and other docs 3. Frost. Most development complete. (May 1, 2009) Release Notes should be >90% filled in. Bug Hunt: 500 points Post inkscape-0.47-alpha.tar.gz 4. Feature Freeze. No further development work. (May 15, 2009) Disable features that can't be finished in time. Focus on critical bug fixing. Finalize all tutorials, docs, etc. Finalize all extensions. Translators create translations. Inkscape must pass 'make distcheck' Post inkscape-0.47-beta.tar.gz 5. Hard freeze. Only release wardens can commit to mainline. (May 25, 2009) No further string changes. Focus on release-critical bug fixing. Finalize translations, release notes, etc. Packagers test creating pkgs of the -beta release. Post inkscape-0.47-rc1.tar.gz 6. Branch. Establish the Stable Branch for release (June 5, 2009) Complete any late-late-late work. Final verification of packaging, release notes, docs, etc. Publish more release candidates until ready for release. Plan 0.47.1+ release(s), if needed 7. Release. Post inkscape-0.47.tar.gz (June 15, 2009) Post packages Post official announcements 8. Open development. I know it is a radically short timeframe, especially given how long 0.46 took. However, our last few releases have been dragged out to a painful degree. Honestly, it seems like most people loathe the process now. So... let's rip the bandaid off and just make it happen. We can modify the schedule at any point of course, but we need to address our biggest issues IMMEDIATELY to attempt to keep the dates as close as possible. This is doable. We're good, we're smart, we're competent, and we have the resources... we just need to be focused to make this happen. Cheers, Josh P.S. As all can see, I'm attacking the bug tracker... I hope other non-coders will contribute to preparing the bug tracker for the bug hunt too (let's free up the bug fixers time to actually fix things, rather than wade through the current mess).
