Is not importing the text as > text via Poppler a bug or what we should expect? Please post a link to an example (any PDF somewhere on the web) and describe the region you are talking about. PDFs have a broad spectrum of how text is encoded and without seeing the example we can't be sure where the issue is. These PDFs all look the same on the screen, but... The best case encodes each letter as its own glyph, and the encoding matches up with unicode. These are searchable with text strings in PDF viewers. Not quite so good, the PDF merges pairs of letters like "fi" into one glyph. This looks good as a graphic but causes hiccups when it hits any text processing code. These are mostly searchable, but (in this example) "file" would not be found, even when the word is staring the user in the face on the screen. Compensating is possible in special cases if there is a table of the common instances of this, and the import code splits out the merged glyphs. Really bad, PDF embeds glyphs and assigns arbitrary codes for each glyph, so that there is no correspondence whatsoever between the encoding and UTF or ASCII. These cannot be searched and will be imported as gibberish. Miserable to straighten out, but in theory it can be done by first searching each embeded glyph from the PDF against the corresponding font (assuming that can be identified), to make a table that back translates to unicode. Impossible - PDF converts text to graphic draws and there are no explicit glyphs whatsoever. This normally only shows up if the exporting program has told the program generating the PDF to do this. It might happen without the user being aware of it if the export code passes through a stage where it is forced to bitmap text in order to satisfy some special effect the program uses that cannot be represented in PDF (or in some cases in Postscript, if the PDF driver goes through the usual Windows Postscript driver.) For instance, if the transparency of the text is 0.001 (instead of 0.0) many postscript drivers are going to bitmap that text to satisfy the required transparency. The end user may not be aware that transparency is not 0, since on screen the two cases are indistinguishable. Regards, David Mathog mathog@...1176...

patch: merge pdf import via poppler-cairo into native importer
by the Adib 17 Jun '14

17 Jun '14

Hello, as already discussed here is a patch that moves the pdf poppler-cairo importer into the native pdf importer. Thus it obsoletes the current pdf-input-cairo importer and removes from the source three. If nobody complains I will go ahead and commit within the next days. Regards, Adib. --

by Jabiertxo Arraiza Cenoz 15 Jun '14

15 Jun '14

Hi to all! I finish my first "a bit producced" video [1] about SpiroLive feature in inkscape. I want to do the same whith all others features i develop... For the moment in the video page i put a share of all sources i use to develop the video. Thanks to Martin, Gez and Gabo for his gratefoul offer to make off-voice, maybe in futures videos i ask to them but while(is enought easy) i could work whith videos and youtube notes... The music is far away from the video, like usual and want. Thanks for your 5 minutes of your live. Jabier. [1] https://www.youtube.com/watch?v=bFakiI5f0-Y

Google Summer of Code Reunion 2014
by Josh Andler 14 Jun '14

14 Jun '14

Hey All, This email concerns current and past participants of Summer of Code who have worked with Inkscape. If you have been or currently are a mentor, admin, or student with the Inkscape project for GSoC (and did not "fail") you are eligible to attend this year's Google Summer of Code Reunion at Google HQ in Mountain View, CA, USA this October. If you have successfully participated with us for GSoC in any of those three roles and you have an interest in attending, please read more here: https://sites.google.com/site/gsocmentorsummitstudentreunion/home As usual, Google will be providing funding (up to $1100 per person) for two people from our project to attend. They will also be having a lottery for other people to be able to attend (no guarantees that anyone who enters from our project will be selected), however, they will not be providing any funding for those attendees. The board is currently working on figuring out to what extent we would be interested in funding this ourselves, if any. If you are interested in attending, please respond right away as we need to solidify plans much earlier this year than in the past. If you have any questions, please don't hesitate to ask. Cheers, Josh

VALS Semester of Code
by Alexandre Prokoudine 14 Jun '14

14 Jun '14

Hi, Someone on #krita brought this to my attention yetserday: http://osswatch.jiscinvolve.org/wp/2014/05/23/vals-semester-of-code-foss-pr… "The VALS Semester of Code is an upcoming project that will work with universities andFOSS communities to give students real-world experience working in software projects. Unlike Google Summer of Code, Semester of Code students will be participating for academic credit as part of their degree courses, and we hope that after completion of their project will go on to be effective contributors to the FOSS community. The VALS initiative is a partership of European universities and SMEs who have been working for several months to plan the pilot of Semester of Code, which will run during the next academic year. We have now reached the stage where we are signing up FOSS projects who are willing to provide mentored projects of students. We have already seen interest from smaller, single-company projects to larger software foundations, and would like to see more. If you are part of a FOSS project, large or small, that would be willing to provide one or more mentored projects, we’d love to talk to you about joining Semester of Code. In return, you’ll get an enthusiastic student providing a valuable contribution to your project. The VALS team will be on hand throughout the project to answer any questions and help unblock communication issues between mentors, students and academic supervisors." Opinions? Alex

Notes from LGM Inkscape Meeting
by unknown＠example.com 14 Jun '14

14 Jun '14

Hi all, We had a very good meeting this morning. Nine (9!) Inkscapers were present (partially thanks to the Inkscape development fund). Here is a list of those present: Martin Owen/doctormo (barcode extension, Python, C++) Joakim Verona (artwork, Inkscape with emacs, d-bus, interest in embedded Inkscape) Krzysztof Kosiński (Clipboard, Cairo renderer, boolean path operations) Gémy Cédric/pygmee (extensions, Python, documentations) Sirko Kemter (LGM Host, Inkscape trainer) Elisa de Castro Guerra (documentation, translations) Ryan Lerch (Redhat user) the Adib (translation, Cairo, interest in PDF output) Myself Here are some notes I took from the session merged with some notes from Elisa (thanks!). We covered a lot of stuff. Let me appoligize to those present if I get some details mixed up. 1. Community Development The Inkscape community appears to be quite weak compared to other projects. We discussed a variety of reasons for this and possible solutions. * The community appears to be quite fragmented due to multiple websites for code, bug-tracker, mailing lists, forums, etc. We should consolidate where possible. There could be better linkage between sites. The Inkscape website still needs to be expanded. For example, there is no page for translators (already fixed since our meeting, thanks Elisa and Martin!). Also, we need make sure that feature requests in the Inkscape forums get aggregated to the developers email list. Martin will try to find someone to volunteer to act as liaison. * There appears to be a lack of direction. The Inkscape board is, by design, limited to controlling Inkscape's donations and trademark. Having some kind of steering committee might be beneficial. * There is a lack of visible momentum in the project, exasperated by the long time between current releases. (We desperately NEED to get 0.91 out - as well as 0.48.5. People need to see progress.) More news articles are needed (with rapid translation). * Paid developer: Synfig hired a developer who is now paid month-to-month by crowd-funding. This has actually stimulated additional developer contributions. People see progress being made and are more likely to make their own code contributions. There are weekly updates by the developer where people see the progress being made. (This is in contrast to the prevailing view inside the Inkscape community where paid development might threaten further contributions by non-paid developers.) Blender uses a subscription system. Many communities use a voting process to select the direction of paid development. We do need to be careful, as Scribus had a bad experience with a paid developer disappearing without delivering promised code. http://libregraphicsworld.org/blog/entry/crowdfunding-for-sustainability-sy… * Extensions is a place where people can easily make contributions. We need a web page with links to contributed extensions (or host them ourselves). (BTW, Blender had 8 part-time developers but still has a very active community of people contributing extensions.) 2. Paid developer We discussed what we would want a developer to do if one were hired. Ideas were: * Animation (high profile, improve sense of forward momentum). * PDF Export (same as above). * Plug-in structure (make it easier to contribute). * Code clean-up and documentation (make it easier to contribute). * Release (get timely releases out). * Testing 3. Website Translations Several problems were identified with translating the website. Translated news is being shown twice, once in the translated language and once in English. Martin and Adib will look into fixing this (some python coding). Also, translators are not notified of news updates. Martin will assemble a list of translators and set up a "cron" job to monitor changes to the website and then notify translators when changes are detected. 4. Technical discussions: * 0.91 release: We need to get this out, even if there are a few remaining bugs. Adib will help with Windows builds. There is great demand for a GTK3 OSX build. It seems that the only hold-up is redoing the rulers as GTK3 dropped the ruler widget. Gimp has the same problem. * Testing: We need better automated testing in both rendering and in unit-tests. cxxtests is awkward to use (and nobody seems to look at it, their are many tests failing now). * Patch reviews: We need to be quicker in reviewing patches or we risk losing new devolopers. We might need to revisit our very easy access to code check-in rights. A person writing Python extensions might not be as proficient with C++. * PDF Export: We discussed various strategies for improving our export to PDF, especially focusing on CMYK. Krzysztof has some ideas for achieving this. After our meeting, we had further discussions with people from Scribus on this topic. This topic is also coupled into possibly supporting other rendering methods (e.g. GEGL). There are a couple possible solutions. One is to extend Cairo to handle color profiles. This might not be so hard as we could write out RGB but include a color profile to hand RGB to CMYK conversion. One problem is that Cairo doesn't support the color-depth we would like. The second is to write our own PDF exporter. While Scibus's PDF export code is tightly coupled to the rest of Scribus, it can serve as a good model of what we need to do. The current "recommended" way of getting good PDF CMYK files is to pass Inkscape's SVG through Scribus. This is problematic as SVG support in Scribus is behind Inkscape's. Filters are not supported in Scribus. Adib will look in to possible filter support in Scribus. * Export: Our export mechanisms needs to be unified, probably with a "visitor's" model. * Filters: Needs to be reworked to follow the model of other objects. (There are hacks needed now to get the rendering done correctly.) * Multipage SVG: We discussed ways to use groups (layers) to handle multipage SVGs. The layer dialog might be modified with some added Inkscape name-space attributes to have groups of layers of which selecting one will hide the others in the group. (This would make editing JessyInk presentations much easier!) Martin has volunteered to put a plan together. * Remove need for "id" attributes. (Krzysztofv has an idea on this.) * Excessive signaling. Why does dragging a gradient handle cause closed dialogs to call style handling code? * Redhat/Gnome/Fedora had a series of requests already forwarded to the mailing list. * BZR migration: BZR is no longer under development.

GSOC status report - Better support for SVG paints
by Tomasz Boczkowski 13 Jun '14

13 Jun '14

Hi! GSOC 2014 program started a week ago. I would like to describe, what I have done since then in my project. The branch, I'm doing my development in is lp:inkscape/~penginsbacon/ inkscape/svg-paints-support. Week 1: 1) The main objective was to refactor c-style UI widgets to c++ and gtkmm. I managed to fully port SPColorSlider. It is now called Inkscape::UI::Widget::ColorSlider. The class works with both GTK2 and GTK3 libraries. Sadly, this partial task took me longer than I expected. Understanding gobject object model was quite difficult. 2) The topic of refactoring ColorSelector and related classes is being actively discussed with Jon A. Cruz at the mailing list. He mentioned possible problems with Gtkmm widgets that I was not aware of before. 3) Simple changes to SPPattern class are in progress. They consist in: a) moving c-like functions to class methods b) getting rid of GSList c) replacing gchar* by Glib::ustring d) converting *_set fields from guint to bool e) converting giuint fields to enums.

FYI - revision 13417 eliminates routine duplication of gradients in list
by mathog 11 Jun '14

11 Jun '14

For a while now we have been working on eliminating duplications of swatches and gradients when these are imported or copy/pasted from window to window. While working on bug #1318657 I put in a change that also eliminates duplications of most gradients shown in fill/stroke when they are cut and paste in the same window. These changes were committed to trunk at revision 13417. I think the new behavior make sense but it is certainly going to look strange if you are accustomed to a huge number of gradients piling up in that list. For a better description see https://bugs.launchpad.net/inkscape/+bug/1318657/comments/12 and also post 14 there. Thanks, David Mathog mathog@...1176...
