Bug tracker maintenance
by Josh Andler 16 Mar '12

16 Mar '12

Hey everyone, If you're a developer and have a chance sometime soon, please visit the bug tracker to view what bugs are assigned to you. If you feel a bug assigned to you is wrongly assigned or that it is unlikely that you will work on that bug, please unassign yourself. We don't want to discourage anyone from taking on a bug because someone else's name is on it. As long as my LP-fu isn't bad (forget the stats on the bug page, I did it not including bugs marked "fix committed") the bug tracker currently has 1,791 open bugs (wishlist not included), 748 are marked as new, 167 marked High, and it appears that bugs w/ patches is at 84. Those numbers aren't horrible, but I'm sure there are a number of bugs that can probably be closed at this point. If you don't code, but want to help the project, you can give us a hand by trying to help us reduce the number of "New" bugs mentioned above. Trying to reproduce bugs is always helpful if they're not confirmed or if it looks like it was last confirmed a couple years back (or on old versions). I'm not sure if the tracker is as open as it was, but hopefully you can modify the status and such without needing to be a team member. If so, please review http://wiki.inkscape.org/wiki/index.php/Bug_management to find out how we do things. Any Qs, as always, please don't hesitate to contact me. Cheers, Josh

This of course triggered me to see if I could hack buildtool to do parallel builds. It turns out to be extremely easy to do so! See rev. 11087 Rebuild buildtool with "-fopenmp" and then you should be able to use the "-j" (20 parallel threads) option or e.g. "-j 4" (4 threads). Needless to say this speeds up a clean build tremendously on i7 2600K: 7 minutes. It is somewhat buggy, but who cares You have to run btool once more without "-j" to get a build done. Someone should be able to fix that... Cheers! Johan

Circular Arrangement
by Denis 14 Mar '12

14 Mar '12

Hi Community, I wrote some days ago about circular arrangement. I'm still busy writing a proposal document (which I need for the Software Engineering course, this project is part of). As soon as I finish, I'll let you know. In the meantime, I've done some mockups, you can find at http://www.pasteall.org/pic/28214. Let me know what you think. - The first part of the dialog("Anchor Point") is the point that should be used to arrange the objects on the circle. - The second part is used to select what the circle/ellipse/arc to put the objects on is. Note: I've put Radius x/y in there, because this allows to have ellipses. - The angles are used to describe an arc - Finnaly if Rotate objects is turned on, the objects on the circle will be rotated (e.g. If you're trying to arrange the stars in the european flag, you should turn this option off) By the way, as someone suggested, I should put this feature in the "Rows and Columns" panel. As IMHO this panel is somewhat messy (especially the align selection), I also thought of ways to improve that. Denis Declara

Surface synthesizer?
by Jasper van de Gronde 13 Mar '12

13 Mar '12

Is there any particular reason that the morphology filter uses something called a "surface synthesizer" (or something along those lines)? Its time complexity currently depends on the structuring element size, and I wanted to fix that, but to do that I need to be able to keep some history, as well as delaying the output until enough data has been gathered. Is this possible at all within this scheme? If not, is it okay if I just copy-paste ink_cairo_surface_synthesize - gut it - and write a few simple loops? (Or am I missing something?)

Nightly 0.49 download/compile.
by john Culleton 13 Mar '12

13 Mar '12

I build the latest and greatest Scribus versions overnight. Now I would like to do the same for Inkscape 0.49.x. If possible I would like to do an svn download. If not just a tarball of the source would do. If Bazaar is the only path I will learn that. But I prefer the more familiar svn path. I have Slackware Linux, and don't want to make an Ubuntu partition just for Inkscape. Please show me the pointers needed to download the latest 0.49 nightly. -- John Culleton Free list of books for self-publishers: http://wexfordpress.net/shortlist.html Police Procedural and Expose: "Death Wore Black" "Create Book Covers with Scribus" http://www.booklocker.com/books/4055.html

New Cairo release rumors...
by Tavmjong Bah 12 Mar '12

12 Mar '12

A couple of weeks ago on the Cairo mailing list there was a request for a release engineer to drive Cairo 1.12 home. Do we have anything that we want to see in the next Cairo release? I seem to recall there being an issue with being able to set the EPS bounding box. Any others? Tav

CMake: parallel builds
by Johan Engelen 11 Mar '12

11 Mar '12

Hello all, Does the cmake build work well on Linux? I wonder if parallel builds work with it. For lib2geom, which uses cmake, parallel building does not work. If it works for Inkscape, we can try to compare and see where things go wrong for lib2geom... Thanks, Johan

Feature proposal: erase mode (and other boolean modes) for drawing tools
by Valerie 11 Mar '12

11 Mar '12

I'm just running this by the mailing list to see if it's worth a feature proposal before submitting it. Feature: boolean modes for all drawing tools. 1. Select an existing object 2. Select a tool of your choice (say... Pencil), with Exclude mode activated for example. (boolean modes appear as small icons in the toolbar) 3. When you draw a shape, the originally selected object does not get un-selected. When you finish drawing your shape, Inkscape automatically chips away at the original shape. The original shape still does not get un-selected until you select something else, so you can continue chipping away at it. Exclude is just one mode, you can have addition, intersection, etc. It applies to both drawing tools and shape tools. I was inspired for this by 2 things: - Krita's "erase" mode. You can basically take any paint tool and activate an erase mode to make the eraser much more interesting. - I never use the eraser. The round shape just isn't too convenient. : ( Thinking about it now, Gimp has similar options for selection tools. I often draw a rough shape and slowly refine it by zooming in before adding to it or chipping away at it, so this feature would streamline the workflow a lot. (also, it took me a while to remember the boolean operations, I imagine shortcut-phobic users would appreciate this feature a lot) Also makes it easy to make quick holes.

Converting SVG to HTML5 Canvas and extensions folder
by Karlisson Bezerra 11 Mar '12

11 Mar '12

Hello! I'm Karlisson Bezerra, from Brazil. I use Inkscape since 2005, to draw comics and other stuff: http://hacktoon.com Some time ago I started developing an extension to convert SVG to HTML5 Canvas, ca to provide Inkscape the hability to generate Canvas graphics without having to write Javascript code. You can see the roadmap on the Github page, and check on the progress of the project: https://github.com/karlisson/ink2canvas This was my final graduation work and I'd like to hear from you about it. My friend Felipe Sanches granted me write permission to the repository but I still not updated the code there with the last commits in Github. Note: I have already two submissions to Inkscape project. The first was the Split Text extension that is already deployed on the last releases. I have some good plans for the future of this extension, and it will get even more useful when Inkscape support SVG animation. For now, I want to create a framework for generating objects that encapsulates the code produced by the extension and can be invoked any time. This can be used in games for drawing characters and stuff. For you who programmed in Flash Actionscript, this would be a rough prototype of a "MovieClip" object. Also, I'd like to ask something: this extension needed more than one file because of its complexity. But, just putting all files in the extensions folder would scatter them, and this isn't an organized solution. This is what is happening today. My solution to this problem was copying the inkex.py and other Inkscape modules to the lib folder in my project, so people won't have to do nothing to test the extension. Actually I'd like to know if we could organize the extensions folder by putting each one in its own folder. Inkscape would read the folder the same way it reads an INX file. An extension would be recognized only if it would have an INX inside of the folder. That's all, folks :D -- --- Karlisson M. Bezerra http://hacktoon.com
