Fix for "easy-fix" bug "Tweak tool using wrong cursor", a few beginners questions
by Christoffer Holmstedt 18 Apr '13

18 Apr '13

I have pushed a fix for https://bugs.launchpad.net/inkscape/+bug/587729 to http://bazaar.launchpad.net/~christoffer-holmstedt/inkscape/lp587729-tweak-… 1) What do I do now as I don't have commit rights (I assume) to inkscape.dev? 2) During compilation of my changes I got an error "pixmaps/cursor-tweak-move-in.xpm:38:35: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]" for all my added cursors but I couldn't see any difference between my cursors and the original ones. I assume that I get the same errors during a full compilation for all cursors but I might be wrong here. 3) I added "--fixes lp:587729" to my bzr commit command but when I pushed to launchpad the status of the bug wasn't changed automatically, I expected it to change to "Fix committed". What is expected behaviour? Regards -- Christoffer Holmstedt

GSoC 2013
by Arshdeep Singh 17 Apr '13

17 Apr '13

Hello all, I am currently pursuing my undergraduate studies in Computer Science and Engineering at Delhi Technological University , New Delhi , India and am looking forward to be a part of GSoC 2013. I have been using software like Adobe Illustrator and Photoshop since before high-school. With the interest I had in programming and algorithms, I always wanted to contribute to such software programs. FOSS caught my attention in my second year of college and I began delving into Inkscape as it provided me an opportunity to get inside the workings of a real software almost similar to Illustrator. I have fixed one bug till yet: https://bugs.launchpad.net/inkscape/+bug/773288 *I intend on implementing a Recolor Artwork Tool that shall allow: *1) Managing Color Themes with one go. 2) Enable editing many objects' colors on-the-go (simplified interface). This site should give some idea about what I have in mind- http://colorschemedesigner.com/ Thankyou to ScislaC for pointing this site out and lessening my burden of explaining what the tool would do. The credit for the idea goes to Inkscape's developer wiki which urges the contributors: '*Don’t please the artist—BE the artist'* and in my view, this tool shall be a boon to all of Inkscape's heroes, our artists. I have played around the gimpcolorwheel.c file and studied Cairo's drawing structure to paint the entire Hue Wheel in my experiments. A screenshot (result) is attached for the mentors' and advisors' perusal. Also, I have added a 'Recolor Artwork' option in the 'Object' Menu to house the final tool widget. As an almost rookie for such a project, I hope the discussion with people adept with industry methods and experience in digital designing will definitely help me chalk out finer details of how to structure the tool keeping in mind the intricacies of Inkscape's codebase. Thankyou for your time. -- Arshdeep Singh (demicoder) Third Year, Computer Engineering Delhi Technological University Ph: +91-9654115614 https://sites.google.com/site/adsingh1729/home

Request for http://wiki.inkscape.org account, update to CompilingUbuntu wiki page
by Christoffer Holmstedt 17 Apr '13

17 Apr '13

The wiki states that I should send an email to the dev list if I want a wiki account, so here is that email . I just followed the compiling instructions at http://wiki.inkscape.org/wiki/index.php/CompilingUbuntu on a clean install of Ubuntu 12.04.2 LTS and I had to install the package "autopoint", which is not listed on that wiki page, to get the autogen.sh script working. Anyone running Ubuntu Raring that can confirm that it's the same for later releases than 12.04? Regards -- Christoffer Holmstedt

GSoC 2013 - Embedding of license and attribution metadata
by Christoffer Holmstedt 17 Apr '13

17 Apr '13

Hi I'm studying Master in Software Engineering at Mälardalen University in Sweden and looking in to the possiblities of participating in GSoC 2013. I've used Inkscape for several years as a user and want a deeper understanding of how c/c++ is used in larger projects so I feel that Inkscape can be a good project for me. Enough about me for this time, as Johan Engelen posted in an earlier conversation [1] I will try to spend my time fixing bugs instead of "fine tuning" my GSoC application. So to my suggestion and questions. For the last weeks I've been in contact with Jonas Öberg a Shuttleworth Fellow running the project "License and attribution metadata" [2,3]. With start from the 1st of June 2013 they will begin their work of developing a library for storing license and attribution metadata in digital works. My suggestion for GSoC 2013 is to use that library in Inkscape. There are both benefits and problems that comes with trying to use a library while it's still in alpha/prototype stages so what do you think about this? 1) Is this work of any interest? 2) What do you think about developing the additions to Inkscape as GSoC project in parallell with creation of a library for this?

Re: [Inkscape-devel] Displayig a Tool in the Menu
by Arshdeep Singh 14 Apr '13

14 Apr '13

Hi all, I have been successful in making a menu-item in the *Object* Menu of the name *Recolor Artwork*. Just as an exercise I have copied the Fill and Stroke .cpp and .h files and translated the entire dialog to under the name *RecolorArtwork* rather than *FillAndStroke*. Logically this should mean that the entire dialog box shall now be replicated under the pseudonym of * RecolorArtwork*. To add a menu-item I edited the *menu-skeleton.h* file's variable * menus_skeleton[]. * I added " <verb verb-id=\"DialogRecolorArtwork\" />\n " under " <verb verb-id=\"DialogFillStroke\" />\n " This handles the display part of the task. Now what remains is linking the action and verb. I added a enum value: *SP_VERB_DIALOG_RECOLOR_ARTWORK* in *verbs.h* and in *verbs.cpp * I added: *new DialogVerb(SP_VERB_DIALOG_RECOLOR_ARTWORK, "DialogRecolorArtwork", N_("_Recolor Artwork..."),* * N_("Description of Recolor Artwork..."), INKSCAPE_ICON("dialog-fill-and-stroke")), * This links the verb *SP_VERB_DIALOG_RECOLOR_ARTWORK *and * DialogRecolorArtwork. * In the same file *verbs.cpp*, I added: *case SP_VERB_DIALOG_RECOLOR_ARTWORK:* * dt->_dlg_mgr->showDialog("RecolorArtwork");* * break;* in the function: * * *void DialogVerb::perform(SPAction *action, void *data) * * * which launches the appropriate dialog or rather it should. Sadly this is not the case ?

Grids - new coordinate system
by Johan Engelen 14 Apr '13

14 Apr '13

Hi all, We have to change the coordinate system used by grids in XML. I think it is the only thing left that has the inverted coord-system in XML. I changed it in the guides improvements branch, and it works fine. The only problem is: grids of old files will show wrong, they are not "upgraded" to the new format, because there is (yet) no way to distinguish old-style from new-style grids. How should I go about this? It is relatively easy to fix it manually for each file, but I understand it is an annoyance. Cheers, Johan

Introducing myself and GSoC 2013 student participation
by Jiabao Wu 13 Apr '13

13 Apr '13

Hello, Thanks to you all and the rest of the Inkscape community for making such a great project. I am a masters student at Australian National University. I am currently part of a course on FOSS run by Andrew Tridge and Bob Edwards.This boosted my huge enthusiasm in contributing to the FOSS community and the software I use. For this course I will be making a report on the study of the Inkscape(inc. culture, governance, etc), as well as a report of my work. The experience from my Bachelor of I.T left me feeling like I didn't know very much about real software development. Studying your project has really helped to open my eyes and I want to contribute as much as I can. I sent my first patch recently to fix the too small default window size, which is at https://bugs.launchpad.net/inkscape/+bug/830663. Thanks to ~suv and JazzyNico for testing it. It has not been accepted and is still being discussed. I am looking forward to more recommendations and suggestions on how I can improve the patch. At the mean time, I will try to fix more bugs and send more patches. Finally I greatly enjoyed my short time with inkscape and hope to participate in GSoC as well. Cheers, Jiabao

apply and remove transform ?
by Bric 12 Apr '13

12 Apr '13

I am certain this question has been asked; i found discussions online but no viable solution. Is there a command to "solve" the transform derivation (or shift), store the derivation as constants, and remove the transform directive? This KIND OF happens with paths, when you "simplify path". But that's a big "kind of": "simplify path" actually removes nodes. I'd like to keep all my nodes but get rid of the "transform" attribute (after integrating and hard-coding its effect, in constant values). Possible? Please help! thanks!

Compile Errors
by Arshdeep Singh 12 Apr '13

12 Apr '13

Hi all, I added a new .cpp file in the ' ...\inkscape\src\ui\dialog ' directory. For reference I was using the fill-and-stroke.cpp for creating a GUI for my code. I named the tool say 'XYZ'. Upon compiling XYZ.cpp along with inkscape the following errors cropped up: Make error line 301: problem compiling: src/ui/dialog/xyz.cpp:31:1: error: 'XYZ' does not name a type. Can someone help me in understanding why this cropped up ? I am deriving a class of the name XYZ under the UI->Inkscape->Dialog namespace. Also, in fill-and-stroke.cpp: FillAndStroke::FillAndStroke() : UI::Widget::Panel ("", "/dialogs/fillstroke", SP_VERB_DIALOG_FILL_STROKE), _page_fill(Gtk::manage(new UI::Widget::NotebookPage(1, 1, true, true))), _page_stroke_paint(Gtk::manage(new UI::Widget::NotebookPage(1, 1, true, true))), _page_stroke_style(Gtk::manage(new UI::Widget::NotebookPage(1, 1, true, true))), _composite_settings(SP_VERB_DIALOG_FILL_STROKE, "fillstroke", UI::Widget::SimpleFilterModifier::BLUR), deskTrack(), targetDesktop(0), fillWdgt(0), strokeWdgt(0), desktopChangeConn() What do the highlighted text accomplish ? -- demicoder

Well, no, on linux, sorry. But I don't quite get the problem. There are lots of people who seem to have managed to make a recent version of gcc work on mac os. Of course you'd have to recompile all the necessary libraries from scratch when switching to a compiler with a different abi. As far as I understood that, Apple switched from gcc to clang because newer version of gcc are gplv3? Is Inkscape compilable with clang? -----Ursprüngliche Nachricht----- Von: suv@...2204...

Inkscape helper apps.
by john Culleton 11 Apr '13

11 Apr '13

I am asking this question on the devel list because those who know the answer are likely to hang out here. I know the helper applications like Scribus, Gimp, TeX and Java are needed to use the full power of Inkscape: Scribus for CMYK conversion, Gimp for extended manipulation of bitmap images, TeX for the Latex extension, and Java to support Jessylink. Am I missing any helper apps here? I would include both those called by Inkscape itself and those external to Inkscape but also considered very helpful. What about Imagemagick, Ghostview etc? Since I use Slackware linux I have a pretty complete set of helpers already. But what about the Windows and Mac users? -- John Culleton Wexford Press

GSoC 2013 student participation
by Damjan Velickovski 10 Apr '13

10 Apr '13

Hello, I'm Damjan Velickovski (dummyan) and I want to apply for this year GSoC on this project. I study Computer Architectures and Networking at St. Cyril and Methodius University. This year I became interested in computer graphics and that's the main reason why I choose Inkscape, also the fact that is a well established vector drawing program. Our faculty program emphasise programming in java, so my knowledge of C++ is intermediate. But I already started learning those things that I can do in java but not in C++ and I sure learned new things as well. My key objective with this participation is to sharpen up my programming skills, learn how to work in team and of course make a contribution to the open source community. I use linux about 6 or 7 years and I think it's finally time to pay back some of my moral debt :) I have read the blueprints and their comments and I haven't really decided for what to apply. These are some of them that seem interesting for me: - <https://blueprints.launchpad.net/inkscape/+spec/non-advanced-filters-ui> <https://blueprints.launchpad.net/inkscape/+spec/non-advanced-filters-ui>A filter effects dialog for non-advanced users with higher level abstraction of effects<https://blueprints.launchpad.net/inkscape/+spec/non-advanced-filters-ui> I see that this blueprint already have an assigner, but no work is done and seems to be halted. If you are Felipe "Juca" Sanches, please reply and tell me what are your opinions about handling this to student. If there is no reply I will contact him on the email address provided on launchpad. - Named color swatches dialog <https://blueprints.launchpad.net/inkscape/+spec/named-color-swatches> - Geometric & Tech Drawing<https://blueprints.launchpad.net/inkscape/+spec/tech-drawing> It seems to me that this one have great deal of coding and polishing. Can anyone explain briefly what has to be implemented in order to achieve this? So please post your thoughts. Share some previously GSoC experiences, where students fail most, what is essential to the job, in what way should I construct the application for GSoC. PS I have read the wiki page and I contributed my first patch and after my exams week is over I will try to solve more bugs. Thanks for reading, and best regards!

Glyphs that return no vertical extent information???
by mathog 08 Apr '13

08 Apr '13

In trying to clean up my libTERE text reassembler code so that it works properly with R->L languages like Hebrew I found that the Hebrew glyphs mostly contain no useful vertical extent information, even though this information is present for English language characters. Here is the code (in C, this is not strictly a part of Inksape, but is used by it): int TR_getadvance(FNT_SPECS *fsp, uint32_t wc, uint32_t pc, int load_flags, int kern_mode, int *ymin, int *ymax){ FT_Glyph glyph; int glyph_index; int advance=-1; FT_BBox bbox; glyph_index = FT_Get_Char_Index( fsp->face, wc); if (!FT_Load_Glyph( fsp->face, glyph_index, load_flags )){ printf("DEBUG TR_getadvance 1\n");fflush(stdout); if ( !FT_Get_Glyph( fsp->face->glyph, &glyph ) ) { printf("DEBUG TR_getadvance 2\n");fflush(stdout); advance = fsp->face->glyph->advance.x; FT_Glyph_Get_CBox( glyph, FT_GLYPH_BBOX_UNSCALED, &bbox ); printf("DEBUG TR_getadvance bbox.ymax/ymin %d,%d\n",bbox.yMax,bbox.yMin);fflush(stdout); printf("DEBUG TR_getadvance glyph metrics height %d vertbearing Y %d\n",fsp->face->glyph->metrics.height,fsp->face->glyph->metrics.vertBearingY);fflush(stdout); if(ymin && (bbox.yMin < *ymin))*ymin=bbox.yMin; if(ymax && (bbox.yMax > *ymax))*ymax=bbox.yMax; if(pc)advance += TR_getkern2(fsp, wc, pc, kern_mode); FT_Done_Glyph(glyph); } } return(advance); } When the font is "Century Schoolbook L", for instance all Hebrew strings trigger a series of these output lines: DEBUG TR_getadvance 1 DEBUG TR_getadvance 2 DEBUG TR_getadvance bbox.ymax/ymin 0,0 DEBUG TR_getadvance glyph metrics height 0 vertbearing Y 0 and ymin,ymax are returned as zero. So far only one tested font actually had this vertical extent information for these glyphs - Verdana. The glyph does eventually render OK in Cairo, but not being able to figure out the vertical extent of the bounding box really makes it difficult to reassemble complex text into <text><tspan> structures! Is there some trick for pulling these vertical extent values out when the font itself appears not to hold them? Perhaps a function that will calculate them from the glyph instead of reading them from the font? The only other approach I could think of was to fall back to looking up the vertical extents for some glyph that does have these values, like "A", and applying them for the missing Hebrew glyph. That would be a terrible approximation, but better than saying the vertical extent is zero! Thanks, David Mathog mathog@...1176... Manager, Sequence Analysis Facility, Biology Division, Caltech

new .48 XAML output not compatible with silverlight, PathFigureCollection not supported in silverligth 5
by Damian Hallbauer 08 Apr '13

08 Apr '13

Hello, Thanks for your continued development on Inkscape. Due to all the format wars this the best and only tool i can use for my self-funded Silverlight game. But I'm having a problem. We have been stuck using version .47 and it was crashing allot randomly, but the xaml worked, in WPF and silverlight. finally got .48 to work, it is stable, but i get a problem, its now using PathFigureCollection for any simple path. here is the issue i am stuck with now. http://stackoverflow.com/questions/11331549/why-does-this-xaml-path-crash-s… . MSIE wont draw it. Could you please revert so that the XAML does without the Figures= ? Or set it as an option if you are taking it somewhere needed?. So far i see only one object in the collection anyways. I just downloaded the latest daily build from Skydrive and still see the Figures.. This may affect RT, phone 8 and other developers. Another smaller issues i have: -thinner line weight on paths do not show in xaml. ( this worked in inkscape .47) i work around it by scaling 10x more on my drawing, then import at 0.001 scale. -groups do not show in xaml( this is still broken but i just ungroup for now) we only use simple paths, layers, strokes, and sometimes groups. if my game makes any money after this 4+ years development i will donate. Yours, Damian Hallbauer
