GSoC: KML <-> SVG Translation
by sjatkins＠...2336... 06 Apr '10

06 Apr '10

Hi everyone, I'm interested in applying to create an KML - SVG converter. KML and SVG are similar enough that it makes sense for there to be a way to convert from one to the other. My plan would be: >From now until the end of week 1 or 2: Study both formats and work-out the equivalents between KML and SVG. I know there are features of KML - namely, placemark descriptions, which will not convert directly to SVG. There are probably other features too. I'll try to deal with these in any time I have remaining at the end. I'll also need to work out a way to convert the coordinates systems, and deal with sizing the image - using the KML coordinates, the image would be very small, in a very large document. Then, develop a command-line app that will actually do the conversion. I'll be using C++. I haven't decided on an XML library yet - any suggestions? * Plan the structure of the program. * Focussing first on KML -> SVG, gradually add tags to convert, and check they work correctly. * Once KML -> SVG works, add SVG -> KML. Should be a case of reversing the existing conversion functions. * Write some usage documentation. Once the command-line program is working, I'll start on giving it a GUI. I can't seem to find anything about what UI library Inkscape itself uses - can anybody tell me? It would be better to use the same one, to make maintenance easier. The GUI will send commands to the command-line program, to keep the two separate, and so that Inkscape itself can use the command-line one at some point if needed. * Design the UI. * Implement it. * Write some user documentation. Deliverables: * A command line program that can convert SVG to KML, and back, successfully. * (Probably) A GUI to go with the command-line program. If I get time: * Allow importing/exporting as KML from within Inkscape. * Find ways of handling 'placemark' KML elements, and any others that do not convert easily to SVG, so that a user can convert to SVG, edit, and convert back, without losing anything. Possibly by including hidden elements in the SVG, or using comments. ----------------------- Is this a decent plan? Is there anything I've missed? ~Samuel Atkins

Remove Inkview?
by Krzysztof Kosiński 06 Apr '10

06 Apr '10

Hello https://bugs.launchpad.net/ubuntu/+source/inkscape/+bug/278001 Inkview is large (8MB) and doesn't do much. Does anybody use it? I think it should be removed. This would reduce the size of binary packages as well as installed size somewhat. Regards, Krzysztof

Question on Frost - is this a known issue?
by Jason Smith 05 Apr '10

05 Apr '10

I am new to Inkscape, but have been involved in some open source projects (mainly Java-ish stuff). I downloaded the latest Windows release and tried it out. I am wondering if this is a known issue, since it is so badly broken. (Inkscape April 3 drop, Windows Vista) I am trying to use a Wacom Bamboo tablet. Inkscape looks like it recognizes the tablet, but I can't seem to get it to work with the caligraphy tool. My tablet works with 0.47, after some fiddling. Additionally, there are two GUIs for setting up input hardware now. The old one looks like 0.47, and the new one looks very cool, but for the life of me I can't figure out how to make it work. And keep in mind, it could be user error - I am new to Inkscape. But I am thinking that a Wacom Bamboo tablet should "just work" with a drawing application... Sooooo... are the hardware input dialogs still "in-work"? If not, I'll be happy to provide details and screen shots. I just don't want to clutter your bug tracking system before checking. Thanks!

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

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
