[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.

[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

Paned vs (H|V)Paned and adding it to metadata-properties, namespace error?
by Christoffer Holmstedt 22 Jul '13

22 Jul '13

So working on implementing my mockup sent to the mailing list concerning more advanced metadata editing into Inkscape now. Though I've hit an error I can't understand, any help is appreciated. ### My problem The problem I have is that I can add new VBox and ScrolledWindow without problem to document-properties.cpp|h and compile it. When I try to add Gtk::Paned or Gtk::HPaned I get the following errors. error: ‘Paned’ in namespace ‘Gtk’ does not name a type error: ‘HPaned’ in namespace ‘Gtk’ does not name a type I've tried to add it in a mockup outside of Inkscape and it works. Any ideas what this could be caused by? ### Another question As a side note I'm trying to add a paned window to the document properties notebook which has each page built up by tables/grids. Is it wise to add a Paned window to the this notebook and moving away from the common practices of using the table/grid layout? Regards -- Christoffer Holmstedt

Inkscape Website problems and how to help
by Guiu Rocafort 22 Jul '13

22 Jul '13

Hi ! Today I noticed a problem with the new staging.inkscape.org page. In the "overview" tab the about and download buttons doesn't fit in the same row. I checked it using Firefox 22 and Chromium 28.0.1500.52 both in Ubuntu Studio with the same problem. Looking a little bit closer I noticed there is a 100px margin in the css class : #front-banner-overview.buttons-right #front-banner-read-more { margin-left: 100px; } Reducing that margin to 90px ( for instance, and to let some space between the buttons ) should solve the problem. There is another problem with the news pages. It seems to complain about an error with Django 1.5 but no clue about how Django works at all... Also noticed a problem with the drop-down language menu. If you don't move the mouse fast enough the drop-down closes before reaching it. The problem seems to be the top margin in the drop menu. In that space the mouse is not being detected as being in the drop-menu element. I would solve it adding a height fixed empty div inside the drop-menu with white background so it looks the same but not sure if a good solution. I would like to help solving this problems. Also I can help with Spanish and Catalan translations. So how can I help ? Thank you Guiu Rocafort -- Please avoid sending me Word or PowerPoint attachments.

Design Approach for Directory-Level Extensions?
by George Chriss 20 Jul '13

20 Jul '13

Hi, I'm seeking advice related to Inkscape Bug #1069248: Feature Request: Add 'Export to hOCR' in Save Dialog https://bugs.launchpad.net/inkscape/+bug/1069248 I've published a draft implementation of the extension (see comments) and am currently working on the next step, which is to say the ability to create multi-page PDFs from directories of hOCR html files and corresponding images. I have a standalone, draft version of this script based loosely on HocrConverter ( github.com/jbrinley/HocrConverter ); it's functionality I'd like to develop into a second Inkscape extension, if possible. So, two questions: 1) what steps are necessary to include the 'Export as hOCR' extension in Inkscape upstream? and 2) the 'next step' extension ("Create Multi-Page PDF from hOCR HTML Files" or similar): what would be the best way to integrate this into Inkscape? Most (all?) Inkscape exports/effects/operations operate on single documents, so it's a little different in scope. == An alternative method to create text-searchable PDFs within Inkscape is to open an image, create text boxes with opacity >= 0.4% (tested with Evince 3.4.0), then export as PDF using the current extension of the same name. Downsides to this approach are that the text is slightly visible and the loss of structured metadata (i.e., hOCR) which is extensible to other applications (e.g., DjVu, moz-hocr-editor) Sincerely, George

Hi, I'm getting forward with the refactoring of the old connectors code. I'm still having trouble when changing the connector type but that does not seem too hard. The current code can be found on launchpad at https://bazaar.launchpad.net/~h-e-6/inkscape/connector-wip/changes It is based on revision 12380. The next TODO is cleaning up the connector context code and moving most of the logic from there to sp-connector.cpp. Regards, Sebastian

Unit testing
by Jon Cruz 19 Jul '13

19 Jul '13

Hi guys, First off, I was wondering how many people out there have been running the unit tests along with builds. Secondly, the system we have now probably is in need of serious updating. Some of the test cases themselves aren't passing correctly, but the framework is also outdated. So does anyone have preferences in this area? Is there some framework we should consider other than Boost Test and Google Test. Or has it not been an issue for others and I should just go ahead and update to whatever keeps things working? Thanks.

Only GimpWheel Mode
by Arshdeep Singh 18 Jul '13

18 Jul '13

In my attempts to operate in the mode when the wheel is being used: I made the following changes (the diff file) - added a 'gboolean _isWheel' to struct ColorSelector - added a function (public) void set_isWheel {_isWheel = TRUE } - added a function (public) gboolean get_isWheel { return _isWheel; } -added a function to paint-selector.cpp 'gboolean isWheel' which returns the _isWheel attribute of its selector. Unfortunately, the value does not stick to TRUE. QuesA: Is this approach wrong ? Is there any intrinsic method by which I can get the information that the Wheel is active ? QuesB: Why is this approach failing ? -- Arshdeep Singh Third Year, Computer Engineering Delhi Technological University Ph: +91-9654115614 https://sites.google.com/site/adsingh1729/home

[Recolor] Good News
by Arshdeep Singh 18 Jul '13

18 Jul '13

Hello all, I have successfully implemented the code that enables dragging of the recolor nodes. Right now, any node you drag shall change the color of the entire selection. Another development: I successfully can edit the color from the Desktop. Here it is for future reference if someone needs it. *Inkscape::Selection *selection = sp_desktop_selection(desktop);* * * * GSList const *items = selection->itemList();* * g_printf("\n\n\t\t Prinitng the id's of Selected objects ");* * for (GSList const *i = items; i != NULL; i = i->next) * * {* * SPObject *obj=reinterpret_cast<SPObject *>(i->data);* * Inkscape::XML::Node* obj_repr = obj->getRepr();* * SPCSSAttr* obj_css = sp_repr_css_attr( obj_repr , "style" );* * sp_repr_css_set_property ( obj_css , "fill", "#00ff00");* * Glib::ustring str;* * sp_repr_css_write_string (obj_css, str);* * obj_repr->setAttribute ("style", str.c_str(), TRUE);* * }* * * Now only the linking task remains. By linking I mean the link b/w the recolor nodes and the selected objects so that only the respective node is changing the color of the respective object. I am facing one problem in that respect: Initializing a string, gchar* id = g_sprintf( "obj%d", i ); is giving a runtime error. The same goes with g_snprintf( ..) Any idea whats going wrong ? -- Arshdeep Singh Third Year, Computer Engineering Delhi Technological University Ph: +91-9654115614 https://sites.google.com/site/adsingh1729/home

[Recolor]
by Arshdeep Singh 17 Jul '13

17 Jul '13

Hello all, I am unable to narrow down to the mode when the Wheel is active. (in the code) I have been digging through: sp-color-notebook.h/cpp sp-color-selector.h/cpp sp-color-wheel-selector.h/cpp sp-color-scales.h/cpp I also tried using the SP_IS_COLOR_WHEEL_SELECTOR(o) but I couldn't figure out how to design the final function call that takes as the argument, the list of selected objects when the wheel is actively being used (in the sp-color-notebook) and then changes the colors of the individual objects. This is what is holding me back: Where to put the function ? As a member of ColorSelector ? ColorWheelSelector ? or PaintSelector ? Please help. -- Arshdeep Singh Third Year, Computer Engineering Delhi Technological University Ph: +91-9654115614 https://sites.google.com/site/adsingh1729/home

'path' attribute in mesh branch
by Alex Valavanis 17 Jul '13

17 Jul '13

Hi Tav et al., I noticed that the 'path' attribute was added for meshes in r11406 [1] but it was not listed as being "supported" in attributes.test.h. I wanted to check whether it's safe for me to just change its status to "supported" in the test because it's part of an experimental feature. If we don't do this, the unit test faiils. One possible issue is that the 'path' attribute is listed as only applying to the 'animateMotion' element, while meshes aren't part of the formal SVG standard [2]. Am I reading too much into the meaning of "supported" here? Have I got the wrong end of the stick entirely?! Cheers, AV [1] http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/11406#src… [2] http://www.w3.org/TR/SVG/animate.html#PathAttribute

[Templates] report
by Jan Darowski 17 Jul '13

17 Jul '13

Hi! Last week I've been mainly working on templates filtering and loading info about them from .svg files. This part is ready, but i suspect that later on, some modifications connected with translations can be needed. I've been also diving a little bit in the extensions system to prepare for the procedural templates.

Regression in rev. 12399
by Eric Greveson 16 Jul '13

16 Jul '13

Hi Alvin, After updating to the latest Inkscape trunk, I've come across a regression - boolean operations on paths no longer work correctly. It appears that revision 12399 (Shape calculations - do not quantize the coordinates) is the culprit. I believe this commit attempts to fix the issue of path coordinates being rounded (and hence losing precision) - however, it looks like the boolean operation algorithms rely on this rounding to work correctly, and now fail with certain path data. I've attached an example of an SVG file with two paths. If you "select all" and then perform a "Path/Difference" operation, it produces the expected result in 12398. If you perform these steps in 12399, both paths disappear. (If the attached file gets stripped out for some reason, it's also available at https://dl.dropboxusercontent.com/u/3442233/boolean_regression.svg). I can understand how this error went unnoticed in simple tests - I tried drawing a couple of rects and doing a "difference" operation and it worked fine. Must be dependent on the exact shape of the path, perhaps my example file contains coordinates that give the difference algorithm some headaches due to floating-point precision issues (numbers being squared etc) that the coordinate rounding hides. I guess the best option for now would be for someone to back out revision 12399. Alvin, hopefully my example SVG will allow you to find the source of the bug! Best, Eric

Inkscape logo on the wiki
by Krzysztof Kosiński 16 Jul '13

16 Jul '13

The wiki still has the extremely old and ugly logo instead of the Tango one. (The new one is attached.) Does anyone know who has or can give access to the Mediawiki server, so that the logo may be finally changed? This is not a trivial thing, as I'm sure the old ugly logo is still being downloaded from the wiki and reused by third parties as our "official" visual identification. Regards, Krzysztof

[Templates] translation of xml data
by Jan Darowski 16 Jul '13

16 Jul '13

Hi! I'd like to ask, if any one of you have any ideas how should be some additional data inside .svg files kept to enable easy translation? I mean info about the template (name, description etc) and probably, later on, some field names for procedural templates. Is there any recommended mechanism for translation of this data or should I think of something new? Another related question: is adding template info into metadata element ok or should I add a new one? I'm asking these things because it's pretty important to set it now correctly as later on it will be difficult to change anything. Regards, Jan Darowski

Move Align to Selection
by Martin Owens 12 Jul '13

12 Jul '13

I've been looking at the align-and-distribute code and want to clear it up for use with my new functionality. My idea is to move the core function into selection like this: Selection::align(Geom::OptRect bbox, AlignSide align, bool as_group); That way align-and-distribute can specify the bbox from all it's options and other functions can align selections. It should reduce repetition and allow my code to call more directly into the effective code without navigating the ui specific code. I'd like your thoughts before I spend some time on this refactor. It might also be worth moving distribute too, I have some great UI ideas for how to do distribute with knot handles too. Best Regards, Martin Owens

[Metadata GUI] Discussion about improvements
by Christoffer Holmstedt 12 Jul '13

12 Jul '13

As some of you know I'm working on improving attribution and license features in Inkscape. I've the basic functionality for the backend (modifications in the XML structure) done and have focused on learning Gtkmm the last week. I wanted to show a mockup with Gtk but I was not able to finish it today so I made a drawing of how I want it to be so the discussion can get started. Any suggestions are welcome. ### Current functionality Metadata GUI consist of two "pages" in the document properties tab/notebook view, "Metadata" and "License". ### Limitations Only one entry can be modified from the GUI. With addition of extra metadata elements as child elements for different SVG-elements there must be a way to modify multiple metadata tags. ### Goals Main goal is to give the user an overview of all the metadata included in the document open i Inkscape. ### Discussion In the attached image I've the basic structure on how I envision this GUI could look like. To the left a list view of all metadata elements available, similiar to the XML editor. The right pane include all the settings [1]. The right pane has at the top a preview "image" of the part affected with the current license/attribution information. So in the image I have made a collage of a "car" and a "sun". In the image I've selected the metadata element for the car so only the car is visible in this preview image. This makes it easier for the user to understand which part of an image is affected by the current attribution and license information. As this GUI is very heavy on forms it's hard to copy and paste the information between different objects and could be very cumbersome. Therefore I have added the two options "Copy" and "Append/Paste". This would copy the entire object's metadata to the clipboard and be available to append/paste in another object (instead of copy-pasting ~15 different fields one at a time). License information can be moved to a dropdown/EntryCompletion option instead of a separate notebook tab. (License would also need one Entry field for the URI that is not in the image). Any comments, ideas or thoughts about this are appreciated. [1] In the image I've only drawn "title" and "Creator" but the real thing would include all options available now from the "Metadata" and "License" tabs. Regards -- Christoffer Holmstedt

Regarding Correct Way to get/set SPObject Style Properties
by Arshdeep Singh 12 Jul '13

12 Jul '13

Hello , This is regarding using the functions in style.h to change the fill color of the object currently selected on canvas. I used the following code: void FillNStroke::funcRecolor() { g_printf("Fetching....\n"); SPDocument *document = sp_desktop_document(desktop); Inkscape::Selection *selection = sp_desktop_selection(desktop); GSList const *items = selection->itemList(); for (GSList const *i = items; i != NULL; i = i->next) { SPObject *obj=reinterpret_cast<SPObject *>(i->data); SPStyle *style = sp_style_new_from_object(obj); style->fill.setColor(1,0,0); g_printf("%s",obj->getId()); } } Nothing seemed to work. I found snippets like these in the code: getRepr()->setAttribute(key, NULL, false); On following these lines, I tried setting a red color to all selected objects using getRepr()->setAttribute("style-fill", "#FF0000"); Again nothing works. Could you please gimme a reference to how to use these functions in the right way ? What should be the way if I need to change a specific property of the style of the object ? An example would really be very helpful.
