[Inkscape- Devel][Recolor] Default Arguments Compiling Error
by Arshdeep Singh 26 Jul '13

26 Jul '13

Hi, I have been trying to write a function with a default argument. The function: void recolor_wheel_nodes_init(GtkWidget *widget , int obj_list_size = RECOLOR_MAX_OBJECTS ) { ..... } This gives the following error: expected ';', ',' or ')' before '=' token Aren't default arguments allowed in GTK ? I bet I've seen them at a few places in the codebase before. -- Arshdeep Singh Third Year, Computer Engineering Delhi Technological University Ph: +91-9654115614 https://sites.google.com/site/adsingh1729/home

Handling missing point attribute in input SVG
by Tomasz Boczkowski 26 Jul '13

26 Jul '13

Hello, Since it is my first post here, I would like to introduce myself. I'm CS student interested in FLOSS software and C++ development. I would like to contribute to Inkscape to raise my programming skills and do something good this year. I've begun by solving bug #1202753. For polygon elements in input file, that have empty or no "points" attribute SPShape::curve field is NULL. According to comment in sp-polygon.cpp:125 this should not be the case. When points="", sp_polygon_set does not initialize SPShape::curve. Comment in sp-polygon.cpp:169 refers to W3C note: http://www.w3.org/TR/SVG11/implnote.html#ErrorProcessing. How should this situation be handled in document tree? Regards, Tomasz Boczkowski

RDF nodes
by Markus Engel 26 Jul '13

26 Jul '13

Hi there, I have not been in for quite a while, but now I've got some time to spend on inkscape again! :) I just looked at this RDF thing and I'm wondering whether it should rather derive from SPObject than being so "separated"? I mean, one document has one metadata node and that should have exactly one rdf node in it, shouldn't it? Currently, RDF nodes do not have any counterpart in the object tree... Btw, do you plan on merging the gsoc results before 0.49? Regards, Markus

Making a Windows binary
by unknown＠example.com 24 Jul '13

24 Jul '13

Dear Inkscape developers, I am working on a variant of Inkscape (well, "fork" but with no hostile intent towards such a great project) and while it runs and compiles just file on my Linux box, I haven't managed to make a Windows binary. I tried the native build on Win32 route but `pygobject` is needed (`pygobject.h not found`) for this particular variant. Basically, I think if I just add `pygobject` to the `devlibs`, everything will work out fine but I have no idea how to do this and I was hoping to get a quick answer from one of you since you already know your way around the codebase. If its something easy, feel free to skip the rest of this message which contains details of what I tried. I don't know the first thing about adding the needed paths for cross-compiling with `i586-mingw32msvc-g++` so I failed pretty quickly there (setting environment variables such as CXX worked fine but `make` then failed to find `libpng`). So I tried building on a (shared) Windows machine using MinGW. `buildtool.cpp` compiled fine (with a warning) and running it started the build process with no apparent problem (it didn't recognize the -j flag though) until it didn't find `pygobject.h`, which is obviously missing. I then installed Python and pygobject (using the PyGTK all in one bundle) but that didn't help (pygobject.h is missing), probably because those are runtime libraries with no header files. The entire goal of making such a build is so that I can get some testers. So I'm also happy to hear other options. (I haven't tried a Mac build yet since I don't have access to such a machine to test the output binary.) Thanks for your time (both in making Inkscape what it is and maybe answering my question).

Re: [Inkscape-devel] Inkscape-web what the next set of pages?
by Jared Meidal 23 Jul '13

I think I'm hearing it be helpful if blueprints were created of the staging webpages, to use as scratchpads and landing sites for arrangement of content goals. I have made blueprints before, but if this would be helpful I'm happy to work on it. I'm asking for clarification because I don't want to clutter up launchpad with posts that are not toward the vision that's desired. --Jared

Inkscape-web what the next set of pages?
by Leo Jackson 23 Jul '13

23 Jul '13

Hello Inkscape-web developers, Do we have a place to list the next items to be done; I can see a lot of pages we can move. Are we putting them on the Wiki as a Roadmap or Google Doc or something. Regards, Leo Jackson

Re: [Inkscape-devel] Inkscape Website: Tutorials
by Jared Meidal 23 Jul '13

I can add a list of additional tutorials to the Tutorials webpage [http://staging.inkscape.org/en/learn/tutorials/] if third-party tutorials belong there, such as these: http://www.chrishilbig.com/a-crash-course-in-inkscape/ https://inkscapetutorials.wordpress.com/ http://www.techdrivein.com/2011/08/10-good-inkscape-tutorials-for-vector.ht… http://creativenerds.co.uk/tutorials/inkscape-tutorials/ I see the Videos section many "third-party" tutorials are being gathered there. These ones above are primarily not videos. Thanks for the feedback. --Jared

[Recolor] Moving on: Class Hierarchy
by Arshdeep Singh 23 Jul '13

23 Jul '13

Hello, I started off with the final coding sub-phase for the mid-term yesterday. The whole ColorSelector class and the ColorWheelSelector class and their inheritance is confusing me. I need to get the ColorWheelSelector to access the GimpColorWheel member _wheel of ColorWheelSelector. How do I get hold of that object ? I tried this snippet, but it seems to be in effective ! *SPColorSelector *csel =SP_COLOR_SELECTOR(g_object_get_data((GObject*)psel->selector, "color-selector"));* *ColorNotebook *nb = dynamic_cast<ColorNotebook*>(csel->base);* * * *ColorWheelSelector *wsel = dynamic_cast<ColorWheelSelector*>(SP_IS_COLOR_WHEEL_SELECTOR(nb->getCurrentSelector())); * * * *GimpColorWheel *wheel = wsel->getGimpWheel() ;* *gimp_wheel_func ( wheel ); * Also, I need to get ColorWheelSelector because to my understanding, changing the colors from the ColorWheelSelector class object shall be a good idea. Please correct me if I am wrong in my thinking. For the final working model I will have to cut off the selection signals from the ColorWheelSelector object so that the entire selection's color isn't changed when I edit the colors on the GimpColorWheel. I hope I am clear with my doubt on the design of the interface. Its mostly 'Where to place the interface that makes the final changes'. -- Arshdeep Singh Third Year, Computer Engineering Delhi Technological University Ph: +91-9654115614 https://sites.google.com/site/adsingh1729/home

Removal of assumed dead code, tips and trix, workflow and testing(?)
by Christoffer Holmstedt 23 Jul '13

23 Jul '13

While working on the metadata enhancements I've realised that there are quite a few lines of dead code. Even the entire file of document-metadata.cpp|h seems to be left overs from 0.48 when Document Metadata was in its own window (now within document properties). With limited testing going on (or perhaps just me missing out on it?) what is the best practice to remove as much dead code as possible and nothing more without breaking stuff? ### On a more specific problem I've just tested to remove src/ui/dialog/document-metadata.cpp|h from Makefile_insert and done a clean build though I ended up with a compilation error that I've a hard time understanding. First of all I think that the DocumentMetadata is instantiated somewhere though the error message points to panel-dialog.h which is a template and to "/panel/home-dialog.h" which is a file I don't think exists in the source. Any help is appreciated. Last lines from "make" error attached in text file. Code available at https://code.launchpad.net/~inkscape.dev/inkscape/document-metadata-code-cl… Regards -- Christoffer Holmstedt

[Tracing] Report #5
by Vinícius dos Santos Oliveira 23 Jul '13

23 Jul '13

Hi folk, I've been battling against splines extraction lately and my code is kind of messy (uncommitable). I've realized I was getting confused and decided to write a summary about what I'm doing and this would help me to get code faster. So, this "progress update post" is located at http://vinipsmaker.wordpress.com/2013/07/21/splines-extraction-on-kopf-lisc… . Well, I think I need to apologize for don't give news about the project too, but my punishment is several hours under the dictatorship of the great lord Pomodoro <http://en.wikipedia.org/wiki/Pomodoro_Technique>. I hope to get something useful to show ya. -- Vinícius dos Santos Oliveira https://about.me/vinipsmaker
