Inkscape - GSoc Application
by shruthy r 05 Apr '10

05 Apr '10

Hi Everyone, I'm a third year electrical engineering student at National University of Singapore looking forward to participate in Google summer of code 2010. I noticed that Inkscape was accepted as a mentoring organization. After looking at the project ideas, I decided to go ahead with the exercise. I downloaded Bazaar for windows, as my laptop supports only Windows OS. I have gone through the basic bazaar tutorial. I would like to know what else is expected out of a typical applicant. Kindly help out, Thanks a lot, Shruthy.

Funding budget for improve text-block
by David Marín Carreño 03 Apr '10

03 Apr '10

Hi, all. I'm using Inkscape in a new business I am working on, and I have discovered some blocking-features that are missing (at least, I have not found them in the 0.47 version of Inkscape: - Vertical alignment property for a text block, so text can be shown at the top, the bottom, or centered. - Kerning adjustment for texts. - Tracking adjustment for texts. - Word-spacing adjustment for texts. My new project really need these features from Inkscape, so we'd like to provide funds for the project so they can be included as soon as possible. As we are currently in the process of getting funds from investors, I'd like to know what would be the approximated budget for implementing these features, and how log it would take (approximately). Thank you very much for your kind support, and for creating Inkscape. -- David Marín Carreño stylomate.com

Reducing dependency on SP_ACTIVE_DESKTOP
by Jon Cruz 03 Apr '10

On Apr 3, 2010, at 11:29 AM, Jon Cruz wrote: > Now, it is true that these meta components are dependent on an SPDesktop. However, they do not need to depend on "fetch the desktop pointed to by the global variable held in a known location". Instead it is easy to apply dependency injection (though we probably want to stick with manual instead of framework driven). The *KEY* yet subtle difference here is in changing things away from "a dialog reaching out and grabbing the global pointer desktop" to instead have "a dialog uses the desktop that is handed to it" > > http://en.wikipedia.org/wiki/Dependency_Injection > > Now, I should probably point out that we are *very* close to having those. That is, with just a bit of refactoring we can reach successful dependency injection on the dialogs and panels. There is an update on this point. In cleaning up the Fill & Stroke dialog so I could get rid of the copy-n-paste extra class (along with the plethora of rogue tile bug pattern occurrences) I was able to convert it to be properly dynamic and work nicely no matter if it were floating or docked, single or multiple. (This happened to also fix bug #270623 ""Fill and Stroke" panel is mirrored between open windows") I now have that tracking extracted into a stand-alone class, and have already reused it in a different panel. That new code is at src/ui/dialog/desktop-tracker.h src/ui/dialog/desktop-tracker.cpp Aside from fixing the immediately visible problems such as bug #270623, other improvements also happened as a consequence of the change. One of these is that prior to this a change in one view of one document would cause a cascade of event processing in all other dialogs for all views in all documents. Things had been all wiring themselves to the global inkscape application instance and listening for changes there. After switching to the new DesktopTracker the updated dialogs only are invoked when their specific desktop has a change (in selection, pertinent contents, document reload, etc). And of course there is the added benefit of getting things a little more multithreading friendly. That will be good too. So far I've not gone out to switch all of our dialogs over to this paradigm. Krzysztof expressed proper concern that we might expose some latent bugs in the process of switching. Since we are very close to 0.48, we should probably only change code that is actively being worked on, so we touch only things that we are looking at and are observing the behavior of. Oh, and if anyone does happen to be working in any code that happens to use SP_ACTIVE_DESKTOP or SP_ACTIVE_DOCUMENT, one minor tweak with a lot of benefit would be to make sure those are only used at the top of a function and are stored to a local variable. Then the function can work against that local variable and gain a bit of safety. And that will make a latter pass to switch things cleaner that much easier. Thanks.

Adaptable UI problems
by Krzysztof Kosiński 03 Apr '10

03 Apr '10

I have some doubts about the adaptable UI feature. Part 1: UI issues - The UI mode selection combo box (called "Task" for some reason) has usability problems: 1. it jumps around when changing mode, so every time I change it, I have to find it again to try another mode; 2. when the main commands toolbar is vertical, it causes a very large horizontal padding on it, even when it's hidden in the overflow menu. - Tearing off toolbars does not adjust their size to fit the controls. If I tear off a toolbar from a small window, I get a toolbar with an overflow menu. If I tear off from a maximized window, I get a toolbar with lots of unused space. This makes tearing off highly useless. - Toolbars can be torn off but can't be attached in a location different that the original one. This is because they use GtkHandleBox, for which the docking position is fixed. At the same time GDL has a widget named GdlDockBar which sounds like a true dockable toolbar (but it might as well be something else, I don't know). Part 2: UxManager class - UxManager::setTask: Magic constants in switch. - UxManager constructor: "tags" is created but doesn't do anything. - What is the point of having several desktops attached to one UxManager? Part 3: util/ege-tags.h, util/ege-tags.cpp - ege-tags.h: It supposedly implements http://create.freedesktop.org/wiki/ResourceTagging but at present I don't see any place in Inkscape that could make use of tagging. - Even if the aforementioned specification was good, the UxManager class apparently tries to do two completely unrelated things: manage external resources and change the UI mode. - TagSet: if I understand correctly what this class attempts to do, it should use std::tr1::unordered_map<Tag, int> with appropriate hash and equality predicates instead of the combination of std::vector<Tag> and std::map<std::string, int>. Part 4: other problems - toolbox.cpp:1578: code related to changing the UI layout uses a switch to assign function pointers. Polymorphism should be used instead. Regards, Krzysztof

GSoC Entry - Inkscape Web Exporter
by Alex Trujillo 03 Apr '10

03 Apr '10

Hey folks. I've been using Inkscape for years, and I couldn't think of a better project to join for my first GSoC. I've written up a proposal on an exporter of vector graphics for various web standards. I have experience using those various web standards over the years, most of which are documented on Google Code. I just wanted to run this by you guys before I submitted it, since I've read something to the tune that some of the best proposals have come from those who have sought community support. Here's the link to the proposal on Google Docs (as a public document) http://docs.google.com/Doc?docid=0AcePN-K69iVuZDI2ajlmYl85MjhjaHhyYnhndw&hl… Nanoblok is a project I've been working on my own for a while: http://code.google.com/p/nanoblok/ My personal website, where I have a great deal of graphics I've made in Inkscape: http://infokraft.org/ I even have an Inkscape tutorial on there I did not too long ago! Well, please lend me your questions and comments! - Alex

Re: [Inkscape-devel] Filter effect and blur background
by Jasper van de Gronde 03 Apr '10

(This is regarding "discontinuities" appearing in blurs, when using BackgroundImage.) Ivan Louette wrote: > Thanks Jasper ! > > Try Yann's file I sent back ; it breaks some times and sometimes not... > > ivan I have indeed been able to reproduce the problem, and found a few copy-paste bugs in Gaussian blur (which normally wouldn't be triggered, and as such went unnoticed) in the process. But the real problem seems to be with the way in which the background image is accessed. In essence the background image doesn't take the area enlargement into account that is needed to correctly render the blur. To properly fix this would probably require a few more changes than I'm comfortable with at this stage in the release cycle, and could take a while anyway, so I've filed a bug (+associated rendering test): https://bugs.launchpad.net/inkscape/+bug/554649

Re: [Inkscape-devel] GSoC - transformation anchors - before apply
by Zhenfeng Zhao 03 Apr '10

03 Apr '10

Hello, Thank you for all feedback a few days ago. I basically have some understanding about the project, which may allow me to start the proposal. In this weekend, I will write a proposal for the project, "Transformation anchors", with all information that I have got, and my ideas in planning. Should I submit it or send it to the mailing list for some feedback first? I will put some responses below...

I definitely will consider them into the plan. I see the possibility to work on these after completing the transformation anchor project, perhaps one or both of them. If there is no time to finish all of these in three months, I will try to make sure on-going work is easy to do. After the three months of work, I may be interested to continue the work, if I have time. Basically, I will do some planning that includes all these relevant tasks. At some point later, it may become clear what can be done. > ------------------------------ > > Message: 5 > Date: Fri, 26 Mar 2010 23:09:30 +0300 > From: Alexandre Prokoudine <alexandre.prokoudine@...400...> > > On 3/26/10, Pajarico wrote: > > > * 2) allow math operations (like sum, substraction, multiplication, > > division) inside the spin boxes for Height, Width, X, Y; and now I > > would add center of transformations. > > Just steal code from GIMP 2.7.0+ :) > > Alexandre > > Cool. I guess I can do that. Stealing from open source is something that I have done for many times, both for Master thesis and at-work programs. Recently, I took some code for spline interpolations into my thesis. Taking code from Gimp should not be too difficult to me. Translating it into C++ is doable too. I do porting of different languages on daily bases. Regards, Zhenfeng.

XDG User Dirs
by Krzysztof Kosiński 02 Apr '10

02 Apr '10

Hello While taking a stab at fixing the command line on Windows, I can also implement the XDG User Dirs specification, using relevant GLib functions. However, there is a slight problem with this: we currently look for user data (palettes, extensions, etc.) in the user's config directory, not in the data directory. The default user config directory on Unix is ~/.config, while the default user data directory is ~/.local/share. Is it OK to look in .local/share? We can automatically create a README in the config directory on the first run that tells the user to move his datafiles to ~/.local/share/inkscape. Regards, Krzysztof
