Removing dead Inkboard code
by Krzysztof Kosiński 24 Jun '11

24 Jun '11

Hello As part of the general theme for the current development cycle, which appears to be "in-tree forks & cruft must die", I have completely removed Inkboard. Here are the reasons. 1. This code is seriously bitrotted and was disabled for a long time, with no one stepping up to put it back into shape. 2. It is behind times. A modern implementation would use something like Telepathy instead of a homegrown XMPP library. 3. Even if it worked, there is a very good chance it would have several remote execution vulnerabilities. 4. I'm not even sure Inkscape is the proper place for such functionality. It's cool, but it looks very much like feature bloat to me. People can do this much better using Google Docs drawings, which can be exported as SVG. 5. The fact that there were no loud complaints about the disappearance of Inkboard around version 0.47 indicates that few people were using it. Regards, Krzysztof

I wouldn't necessarily advocate having a new about screen and trying to create a huge media circus around such a release, I'm just keen to get this into the hands of distros sooner rather than later.

versioning scheme, take 2
by Josh Andler 22 Jun '11

22 Jun '11

Hey all, Almost two years later and there has been no consensus. It is being brought up again due to a brief discussion with JonCruz via IRC. So, does anyone want to change from the leading 0 scheme at this point? Jon mentioned potential of 4.9 as opposed to 0.49, or the year/month method as Ubuntu uses for example, if 0.49 is released in Aug/Sept it would be 11.08/11.09. Bryce had also suggested a year/current system hybrid a couple years ago when last discussed, such as 2011.0.49 (which I guess I'd rather see something like that go more like 11.49). So... thoughts on if we should do this? My vote? Yes... we need to have a solid leading number because that matters (psychologically) to a number of users. Besides, with Google & Mozilla incrementing version numbers in their software so quickly, it makes me feel less like we need to hold to a very developer oriented version numbering scheme. (come on, Thunderbird even flat out gets to skip a major digit, so that lessens the blow if we did do decimal bump for a 4.9 or whatever else imho) Cheers, Josh

Re: [Inkscape-devel] [Inkscape-user] force relative coordinates
by Jasper van de Gronde 21 Jun '11

21 Jun '11

In response to the original question (forcing Inkscape to use relative coordinates): if anyone wants to change Inkscape's behaviour, the relevant code is in src/svg/path-string.cpp, if you need help changing it, just mail me. (Otherwise, I *may* get around to adding an option myself, but it could take quite a while.) On 21-06-11 13:13, A. da Mek wrote: >>> What would be the best way of forcing the path to (always) relative >>> coordinates? > >> The current behaviour is that Inkscape minimizes the length >> of the path data. > > How can the choice of absolute or relative coordinates affect the length of > the path data? Suppose you have a line from 10,10 to 12,13 then "M 10,10 L 12,13" is longer than "m 10,10 l 2,3". When you have very complex paths this can matter quite a bit. In addition Inkscape leaves out the commands whenever it can, to save even more. It could save still more by doing things like removing white space where possible and such, but that makes the path data really a lot less "readable" and offers relatively little in terms of size reduction. > It is so that the absolute coordinates are used when the node is nearer to > the origin than to the previous node? It is actually a bit more complicated. It uses a technique called dynamic programming to decide on a GLOBALLY optimal strategy. So it can pick the longer alternative locally if that means the complete string will get smaller. > Then maybe translate the layer at least of one page width to left and page > height to top, and all coordinates should be relative. > But when I tried to test this idea, I found that the coordinates are allways > relative if the > preference"allow relative coordinates" is checked. > I thought that this behavior maybe changed in a newer version, so I upgraded > from 0.47 to 0.48.1, but still all coordinates are allways relative. I'm not entirely sure what you mean. If you think you have found a case where Inkscape makes the "wrong" decision (that is, it outputs a longer string than necessary), that would be a bug and I'd love to hear about it. If you're seeing it mostly choose relative coordinates, that is because it favors relative coordinates when all things are equal (this tends to avoid switching between the two, as relative coordinates are hardly ever worse than absolute coordinates). > (BTW, the the length of the path data would be better minimized were the > coordinates smartly rounded instead of such values as -113.000006 > or -12.99999) If you see things like that there can be a number of things going on. One problem is that Inkscape (currently) has to write out values in the decimal number system while internally it uses binary numbers (of course). This leads to a whole host of problems, not the least of which is cases like the ones you give (although generally integers aren't a big problem, so that's a bit weird). Then there is the problem that as you move things around (or even place things) Inkscape works with limited precision and errors might accumulate. When the error gets large enough you can get numbers like the ones you give. Inkscape does round the numbers it writes out though, and you can control that through the preferences. Making numbers "snap" to integers when they deviate from an integer by more than the allowed tolerance is problematic at best. Now, unfortunately you do not give the full path in which you see these numbers appearing, but if these are from relative coordinates then there is a good chance that it is a bug. Suppose that you have set Inkscape to use only 4 digits, and you have a line from 1200.2,0 to 1210.4,0. Using absolute coordinates this would be "M 1200,0 L 1210,0". Using relative coordinates this SHOULD become "m 1200,0 l 10,0", and NOT "m 1200,0 l 10.4,0", and Inkscape does have code to deal with this. So if it does not act like this, then you have found a bug and I'd love to know about it. Especially the -113.000006 has me worried a bit, is it from an actual path? If so, can you please send me the full path data? There is a chance that it is legitimate (again, Inkscape can make a locally suboptimal choice if that ultimately leads to a smaller string), but it does not happen that often, so I'd like to see what happened here.

Using xpath in Inkscape code?
by unknown＠example.com 19 Jun '11

19 Jun '11

I would like to be able to select nodes using XPath: https://bugs.launchpad.net/inkscape/+bug/798640 I naively assumed this would be trivial but when I dig in the code it doesn't seem like it is. In particular it is not immediately obvious how to convert between Inkscapes DOM model and libxml2:she model. The simplest way I can think about now is a workaround involving loading the file with libxml2, and find the nodes in that tree instead. I can't be the only one wanting to do things like this. I'm obviously missing something, right? -- Joakim Verona

Getting Inkscape to use the first available font in the > list will be a small step forward (right now it treats a font list as a > single font name and thus won't match anything). I'm not sure if this is completely related to this discussion, but I'd like to leave my 2 cents. Currently inkscape does a rather weird font substitution (at least I, as a user, can't tell how and when it works) and there's no clear indicator of that substitution except the warning icon in the font selector once the text element is edited. In my experience (both with libre and proprietary applications) automatic font fallback has never been completely succesful and frequently it's more problematic than helpful. Manual selection of the replacement is always annoying but at least less dangerous. To make it worse, there's no visual indication that fonts have been replaced in Inkscape, so things can look fine at a first glance when in reality they are very wrong when you sent the artwork to print, exported, etc. Automatic font fallback can be useful for document accessibility, but from a graphic designer perspective it's too dangerous to be considered as a viable option. Since I consider Inkscape a design application I'd say it's more important to actually KNOW that the original font isn't available than finding a quick replacement (which potentially could completely destroy the original design because the character set isn't complete, metrics don't match or simply its style is different). IMO the ideal solution would be the use of embeddable fonts as it was stated before, but meanwhile a safer choice would be to replace the missing fonts using the default (or yes, using some font replacement technique) but making it visually clear the the fonts used in the document aren't the originally assigned, using some highlight or visual cue of some kind. But anyway, before speaking about how fonts have to be replaced, Bug #168658 should be addressed since it's too dangerous for artwork integrity.

Show/Hide objects to export in command-line
by Thibaut Girka 17 Jun '11

17 Jun '11

Hi, I'm using inkscape for various projects, and I'm now concerned about automatically rendering graphics for my game project. However, several images are rendered from the same SVG file, with different layers/objects visibles. While --export-id (and --export-id-only) is helpful in some cases, it's not always sufficient. Therefore, I think hiding certain objects with a new command-line option such as --hide-id would be a worthy improvement. Allowing multiple --export-id might be useful too. Regards, Thibaut Girka.

Guideline snap rotation absolute/relative
by LucaDC 16 Jun '11

16 Jun '11

In rev. 10303 guidelines shift+ctrl rotation has been changed to consider the guide initial angle as base. The absolute rotation was made by purpose, it was not a bug to be fixed. Guidelines are absolute objects and it was decided to make them snap at absolute angles, regardless of their initial orientation. Also, now a relative rotation is made possible by the new math in input fields feature: just open a guide, then write a +15 in the angle field and it's done. Personally I find the "relative" option of little usefullness. Should I need it, there is already a simple way to obtain it, while I use a lot absolute snapping so I can "recycle" guides already on screen rather than throwing a lot, having to clean them one by one. More: the math needed requires trigonometric functions and this makes me think that repeatedly rotating a guide will inevitably lead to rounding errors so you could eventually end up with a guide not starting from where it was at the beginning. This is a huge problem for technical drawings and would force me to carefully avoid using this function (this means always opening the guide menu and input the desired angle or always start from a vertical or horizontal guide and make a single rotation!). I ask for reverting back to the previous behaviour, please. Or add a different modifier for the two options (but we already know that there are less modifiers than the functions involved with guides...). Regards.

Hi. Thanks for setting the PPA! Is it possible to change the name of that builds from inkscape to something like "inkscape-devel" so it doesn't replace the stable build from repos? Inkscape is one of the main tools in my pipe and I give it a heavy daily use, so I cannot afford to have an unstable inkscape, but I don't want it to keep me from testing the new stuff! Being able to install both versions would solve the problem. Thanks in advance Gez.

Use of MINGW64 (minor)
by Bruno Winck 14 Jun '11

14 Jun '11

Hi Everyone, I am on the process to resume my work on Inkscape I did about css. I was using svn, now I have a new computer so I start again fresh with bazaar, so far so good. Since its running Windows 7 x64 I decided to give a try to mingw64. Compiling btool went fine, however when running it allocated 4 gig of memory and stalls. A quick look didn’t help figure out what could be the cause and now I revert to x32. Now I wonder what is the ground of using btool today. Is it still a necessity ? Other projects compile both on Windows and Linux without any specific tool. It would also help to benefit from a real incremental build. Any ideas of what was already tried around btool ? Also if there is already some ideas of having Inkscape addins let me know. I would like some ability to add attributes to svg files like scripts or rdf attributes. -Bruno Bruno Winck Email: <mailto:bwinck@...2633...> bwinck@...2632...

oops didn't send it to the list as well Campbell, Thank you for picking support for the cmake build up. Johan and I authored most of the system but I had given up on getting it to link properly and than went on hiatus from working on Inkscape. And that is where things have sit until today. > - Options from configure's --with/--without This I don't agree with. Cmake should detect all optional libs and use them by default if available. At the end of the configuration generation it should tell the developer what libs are not being used. Similar to what KDE's Calligra does currently. For Experimental features I'm find with this. Thank you again for picking this up if you need anything feel free to ask. I'm going to test this soon. Joshua L. Blocher verbalshadow

CMake update
by Campbell Barton 14 Jun '11

14 Jun '11

Hi Dev's, Over the weekend I found inkscape's cmake files were not working and took the time to update them, * What Works * - building on linux - auto-detecting libs - basic installation - generating config.h, inkscape-version.c - all source & headers listed in CMakeLists.txt * Whats needed * - Inkview target - Options from configure's --with/--without - a CMake module FindDBus.cmake, probably other libraries which are optional too. - CMake currently doesn't install translations, hicolor/icons, or man pages. Probably you already discussed this when first adding CMake but I checked on build times and IDE integration. Including all source files in the CMakeLists.txt files is important for IDE's mainly so they are aware of the headers. I double checked inkscape's source loads in QtCreator/Netbeans & Eclipse. To ensure cmake doesn't get out of sync with the source there is a script which parses the CMakeLists.txt files and makes sure file lists are value and don't miss any newly added files. ./CMakeScripts/cmake_consistency_check.py While a time test at this point is not quite fair, since cmake misses translations & linking inkview I ran one all the same :). Not including configure times and built with "time make -j6" on a 6 core system. cmake: 3min, 38sec. automake: 5min, 56sec. So writing to say the cmake files are (basically) working and if you're a developer who likes fast builds and IDE integration, this part works now. If there is some especially important thing I miss out, let me know and Ill try add it. If other devs want to add support for OSX/Windows, link inkview... etc, that'd be great too. -- - Campbell

Help regarding libcroco node-iface structure
by Abhishek Sharma 13 Jun '11

13 Jun '11

Hello everybody, I am a student selected for GSoC 2011 in inkscape and have undertaken the CSS standardization project. I am currently converting libcroco to be in sync with inkscape's version of libcroco. Now I also have to deal with the tests already provided with libcroco. Test #(1-4) went perfectly, but in test #5 I have to modify the code so that it used the new libcroco function. In that test, initially there was xmlNode and xmlDoc from where we were getting data for instance in one function we had *CRXMLNodePtr a_node = xmlDoc->children*. But libXml has been removed and we do it some other way. This is what I need help in. May anybody please throw some light as to what do we use for initializing parameters for libcroco parsing as in what are the initial values of CRNodeIface and CRXMLNodePtr. Please help. -- Regards, Abhishek Sharma
