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

Meeting: build system on Windows
by Johan Engelen 09 Mar '12

09 Mar '12

Hi all, I would like to have an IRC meeting about the build system on Windows. Although I like buildtool, it cannot do parallel builds, so I am happy to change (back) to something else. And unify it with Linux if possible... I am trying cmake now, but it does not link without errors yet. It is not very encouraging to see the cmake build process get stuck on some intermediate step for a long while, seemingly checking something to find out it does not need to rebuild it. "btool" does this much much quicker... In any case, I'd like to discuss the options. Who's in? Regards, Johan

Re: [Inkscape-devel] Powerstroke cusps
by Valerie 09 Mar '12

09 Mar '12

I've been trying out the powerstroke too, and one of my thoughts on it actually involves poetry on how tragic it is for the sharp edge to be dulled so fast. In other words, I Love the edge, so I'm really sad when it gets cut off so soon. :P Is there a way to control the setting on how soon it gets cut off? I do like them long and sharp! So, other reports: - Thanks for fixing the grouping issue! I can submit a feature request for applying powerstroke to multiple items at the same time, but do people usually submit feature requests for features in the development version? It just seems a bit early. - I've noticed some instability in the rendering. If I do an interpolated powerstroke with multiple cusp nodes and start editing one of the nodes, another cusp node two nodes away (so not the neighbor) may start flickering between the interpolated and beveled states. I don't know how to reproduce this consistently though, and the terminal doesn't say anything strange. I'll try to reproduce it again later and see if I can attach a file. - Applying a stroke to the powerstroke will show lines "inside" at cusp nodes, but I think you already knew that. Still, this is shaping up nicely, and will definitely be an amazing feature for the next release!

Powerstroke cusps
by Johan Engelen 08 Mar '12

08 Mar '12

Hi all, I've been working on cusps on powerstroked paths. And I've obtained a first success. The attached picture shows a comparison between how powerstroke strokes thick cusps, and how Inkscape does it normally (I suppose according to SVG spec). I think the powerstroke solution is more artistically pleasing, what do you think? :-) Cheers, Johan
