Paste attributes
by Martin Owens 21 Apr '13

21 Apr '13

Hey devs, I've been tracking this bug: https://bugs.launchpad.net/inkscape/+bug/1107924 Dragging symbols to the document 'pastes' them in. The 'use' element created points to the symbol definition. But it also adds width="1" height="1" to the element which is erronious. sp-use.cpp sets width and height to 100% (1.0 + SVGLength::PERCENT) and I thought that might be the culprit, but it's not effecting these use elements. So I traced the copy process, outputting the xml at each step through the copy process. The use element created and passed around never has a width and height attribute and setting one gets overridden. So I'm at a loss, the element from the paste process acquires attributes by some magic I can't yet trace. Any help understanding what's going on would be great. Best Regards, Martin Owens

The first answer here describes the use of extern "C" quite well: http://stackoverflow.com/questions/1041866/in-c-source-what-is-the-effect-of -extern-c It is used to prevent name mangling so you can link together e. g. c object files and c++ object files. I think in Inkscape it isn't necessary at all as the c++ compiler is used for all the compiling. Markus

Preserving shapes better when deleting nodes
by Alexander Brock 19 Apr '13

19 Apr '13

Hi, I've been using Inkscape quite a while now for tracing cartoon-like images. The paths usually end up having way too many nodes which is a problem for the vinyl cutter I use to plot these images. I tried using the simplify path tool but it makes the path usually too simple and changes the overall appearance. Therefore I use the path tool (F2) to select unneeded nodes and delete them, but this leads to curves which poorly resemble the original curve, so I have to adjust the curve by hand which consumes a lot of time since I have to clone the path first so I can see the original shape and adjust the simplified curve to fit it better. I made some examples, see attachment demonstration.svgz. I also formulated a target function for minimizing the distance between two curves and calculated the partial derivatives of this function. I'm pretty confident I will be able to use a gradient based method for finding the two control points which lead to minimal distance between the original curve and the new one. Thoughts? Sincerely Yours Alexander

G_BEGIN_DECLS
by Arshdeep Singh 19 Apr '13

19 Apr '13

I was studying the code structure in ' gimpcolorwheel.h ' . I see 'G_BEGIN_DECLS' which is a miscellaneous macro : https://developer.gnome.org/glib/2.33/glib-Miscellaneous-Macros.html#G-BEGI… Is it used only for the files that are C based and compiled using a C++ compiler ? What is its relevance with the given file ? Thankyou for the help. -- Arshdeep Singh Third Year, Computer Engineering Delhi Technological University Ph: +91-9654115614 https://sites.google.com/site/adsingh1729/home

Re: [Inkscape-devel] GSoC13: Text Tool Improvements
by Valerie 18 Apr '13

As far as the text-tool drop-down is concerned, I totally think it should steal the interface Krita uses to manage paint modes. Mock-up: http://i49.tinypic.com/eq1fep.png Fonts would be stored in categories, and within categories, you can check a box to make the font appear in the "favourites" category on top. Uncheck to make it disappear again. This could solve pre-rendering issues: fonts will only render once you open a category. I'm not a font expert so I don't know how they should be categorized though. I'm aware that Inkscape doesn't have that widget, but it totally should, especially for managing the fonts drop-down. It's really handy for managing the dozens of modes in Krita, I just have 5~6 favourites and I can ignore the rest, but still access them easily on the rare occasions when I need them. ------------------------------ Message: 3 Date: Thu, 18 Apr 2013 13:10:58 +0200 From: Stojan Dimitrovski <sdimitrovski@...400...> Subject: [Inkscape-devel] GSoC13: Text Tool Improvements To: inkscape-devel(a)lists.sourceforge.net Message-ID: <CALTcmgnhPXwOv+9tFNO3A+7G7nK7sYOw2V1u1euT2LMhCuVtvA@...401...> Content-Type: text/plain; charset="utf-8" Hello everyone, I'm Stojan Dimitrovski, a sophomore from Macedonia.

I have a few ideas on improving the current text tool, particularly its user interface and some of its underlying features and implementation. Here are some of those ideas: - Typefaces' names should be rendered in the glyphs they describe if such exist. Example: Helvetica should be rendered in Helvetica, Garamond in Garamond, etc. Icon typefaces are rendered by the fallback GUI typeface on the system. - There should be a live preview / comparison of typefaces interface which will allow for a better and faster typeface selection. Inspired by typeface pickers like the one in TypeKit or similar. - There should be a character-preview of a typeface, which will show all of the glyphs in a typeface that are defined for it (and make it easy for those glyphs to be inserted into text). This is primarily useful when using icon typefaces (like Font Awesome from Twitter Bootstrap fame). - Improved handling of different variants, weights, styles of typefaces. (Current implementation is a bit flaky handling this.) - Implement a system for SVG font typesetting (actually be able to use the SVG fonts to render text inside Inkscape). - Improve the SVG font interfaces, they really need some love. I'd like to hear your suggestions and comments before I embark on doing mockups of the interface and thinking about the implementation. I should also mention that I'm fluent in the technologies that Inkscape uses, especially in GTK+ (2, 3), GObject, GLib, C / C++. I have general knowledge of the SVG standard.

Questions about Share / Icons
by Martin Owens 18 Apr '13

18 Apr '13

I'm looking at the icons in the inkscape trunk branch and have a few questions: 1. Do we need png and svg versions of the same icons? Don't all target OSes support svg now via gtk? 2. Is pango_icons.svg used at all? I can't see a reference to it in the code. Even though the icons in the file are nicer than those in inkscape IMO. Are these transitional? 3. Where is the swatch/color picker icon currently used for the the symbols icon. I wanted to change the symbols dialog icon. Make something better, but can't find it in the icons.svg or any of the other files. 4. The filter effects icons, are these temporary placeholders? is anyone working on better replacements? 5. OCAL doesn't seem like an icon, is it here because there's no other place for it? Best Regards, Martin Owens

GSoC 2013 Idea Discussion
by Arshdeep Singh 18 Apr '13

18 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

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
