sodipodi:linespacing
by mathog 19 Nov '12

How does sodipodi:linespacing determine the vertical spacing to the next line? From a bit of experimenting it looks like it starts with this: sodipodi:linespacing="125%" and then looks at the maximum font size in all of the <tspan>'s included under the following <tspan sodipodi:role="line" and multiplies those together. So if the largest is 16pt, it uses 20pt for the linespacing. Is there anything else involved, or is that the entire method? Also, if this is all inside a <text> with style="font-size:32.000000pt;font-style:normal;font-variant:normal;font-weight:400;font-stretch:Normal;line-height:125%;letter-spacing:0px;word-spacing:0px;fill:#000000;fill-opacity:1;stroke:none;text-align:start;text-anchor:start;font-family:Arial;" Changing font-size or line-height makes absolutely no difference in the display. Is that how it should be? Thanks, David Mathog mathog@...1176... Manager, Sequence Analysis Facility, Biology Division, Caltech

Inkscape 0.48+devel r11870 and Units
by Jelle 18 Nov '12

18 Nov '12

Hi Guys, Testing this recent build. Inkscape 0.48+devel r11870 So far: New stuff: - Love the Symbol manager. It will greatly inprove productivity. I wish that a similar thing could be done with first level grouped objects and using the same CTRL+select for objects within that. Ehm,.. a small note saying Use CTRL+C to copy might help though, as I tried clicking and dragging first. BTW. If it would follow the rule of always paste in place, it would be a great help in templating designs. - The new text edit docker is great! Would have liked to see a list of fonts used in the document though, so you can more easily select from the fonts already chosen, find out missing fonts etc.. Could that be added to a third tab? Old stuff: - It's the old clip an object and get to select the object rather than the clipped area bug. So my clip displays the size of the clipped object rather than the clipping area. Now really...that is something that needs fixing. BTW,.. using the create copy of clipping object to create area rather than the default. Releasing the clip doesn't recreate a copy of the clipping object on the screen, clippath is left in defs. So I guess the function has to be extended with a function to copy that node back to the correct z-order of the objects. Question: - Does Inkscape already support SVG font display (Tiny, not Full)? I know Mozilla doesn't support it and probably never will, but I really would love to use them regardless. I have several use cases in mind that are uniquely possible using SVG fonts and don't care if users will have to use "Modern" browsers like ahem.. the rest. Now we can create Glyphs, but I am not sure if it is possible to display them yet. I'll do more testing during the next few weeks, if there's anything you'd like me to pay attention to, please tell as there are a lot of things, new and old. On the Units discussion: The idea is simple Inkscape uses px as units. In the config we can set the amount of pixels per unit, so we end up with 90dpi (standard screenres in 2000) or just set it to 10px per mm or whatever. That way poor buggers like me that design in mm for print and need to get this used on screen won't have to use a calculator to convert the x,y locations with a 6 decimal precision and make these horrid choices on how to handle the half a pixel sizes. Using 3.50xxxx etc. really does my head in at times. Nowhere in the SVG specs does it implicitly say how many PPI to use, it's arbitrary. However, as it was concieved to be used as a screen format, it became pixels per Inch to follow the industry standard. The latter we can blame on Silicon Valley being the place where the early stages of IT were conducted rather than Bletchly Park or Paris. The whole zoom factor is not the issue. It's having a SVG document that has been converted from mm to Inches and then PPI. If I have a 85x55mm businesscard, I'd love to be able to read that in the SVG file as 850x550 px rather than 309.2xxxxx x 190.1xxxxx. That way I can more easily create guidelines and additional objects on screen in my web application without having to calculate every friggin measurement and ending up with those quirky estimations. Maybe Inkscape development isn't always a bliss, but I think with little effort Development using Inkscape can be made a bliss. Adding a setting for Pixels per Unit will greatly improve my sense of bliss at least. For others it may also be a handy way to solve their problems they encounter with scaling if there was an additional recalculator function added to this scaling. That would be a nice extension maybe. "Change/Convert pixels per unit"... Oh joy! I could reset tonnes of hardly usable SVG code with that..! Well,.. Cheers Jelle

Cuestion about branches test
by Jabier Arraiza 16 Nov '12

16 Nov '12

Hello. Im new to develop whith BZR. I develop a branch, and after i made a lot of changes on the branch but i want to know what version of code is better. What i do? 2 branches or update original branch whith the new code. The new code is more powerful but im not sure is ok whith the filosophy of inkscape, because made more changes to the code and change some behviors on usage. Another cuestion is about lang. I want to chage some mensagges in the GUI. IN the core i change it in english but i want to know how to prepare for inernatioalization. Is only one or two mensages in the tip bottom zone. Thanks in advance and sorry for my english. P.D. Think is beter put the mensages in my natural -spanish- lang too?

Cannot build Inkscape with newest Mingw, devlibs36
by mathog 15 Nov '12

15 Nov '12

XP SP3, 32 bit. I had been happily building inkscape branch lp988601 on XP using a version of mingw with gcc 4.6.2 and devlibs32. Yesterday I tried to upgrade this build environment, and while it builds to completion, the resulting inkscape does not run. Method 1. mv ming mingw_save 2. Download mingw-getinst-20120426.exe from sourceforge. Run it, install C,C++ compilers and Mingw Devel. This resulted in gcc 4.7.2 and w32api and iconv installed (the latter two had to be installed separately last time.). 5. bzr checkout --lightweight lp:inkscape-devlibs devlibs Move the folder to /c/progs/devlibs36. 6. modify mingwenv.bat in inkscape directory to use /c/progs/devlibs36. 7. g++ buildtool.cpp -o btool -fopenmp btool -version BuildTool v0.9.9multi 8. bzr revert bzr update bzr revno (11707) btool clean btool (builds to completion) inkscape\inkscape -> BOOOM! inkscape.exe has encountered a problem and needs to close. We are sorry for the inconvenience. 9. gdb file inkscape.exe inkscape.dbg run Program received signal SIGSEGV, Segmentation fault. 0x66533a06 in libglibmm-2!_ZNSs12_S_constructIPcEES0_T_S1_RKSaIcESt20forward_iterator_tag () from C:\progs\inkscape6\inkscape\libglibmm-2.4-1.dll (gdb) bt #0 0x66533a06 in libglibmm-2!_ZNSs12_S_constructIPcEES0_T_S1_RKSaIcESt20forward_iterator_tag () from C:\progs\inkscape6\inkscape\libglibmm-2.4-1.dll #1 0x664e086b in libglibmm-2!_ZN4Glib7ustringC1EPKc () from C:\progs\inkscape6\inkscape\libglibmm-2.4-1.dll #2 0x00bd9e58 in _GLOBAL__sub_I__ZN8Inkscape10FontListerC2Ev () #3 0x00d4a280 in __PRETTY_FUNCTION__.45203 () #4 0x00a5c1fc in aspell_config_retrieve () at ./common/string.hpp:79 #5 0x00000000 in ??

My understanding was that all of the dll's had to be recompiled to work with the newer compiler due to a change in the calling convention, however many of the dll's in devlibs36 have the same md5sum's as do the ones in devlibs32. libglibmm isn't one of these, but libglib is, as is aspell and aspell-import. Suggestions??? Thanks, David Mathog mathog@...1176... Manager, Sequence Analysis Facility, Biology Division, Caltech

Re: [Inkscape-devel] Testing SpiroLive
by Jabier Arraiza 15 Nov '12

15 Nov '12

Thanks for your help Sorin. In spiro paths there are "two kinds of node type" cusp node (all except SYMM node) or spyiro node (SYMM node). I think about to avoid the creation of beizer modifiers, and by default make all clicks SYMM nodes and when you press for example alt key the node is cusp. What we think about this feature? Its the mode i think to use whith the next project B-Spline. The other think can do is retain the spiro pen tool more similar to normal beizer pen, like now, but whith a little effort -work comented in code-, we can make extend the spiro redraw when dragging the last beizer modifier. Whe think is usefool? Sorin i post it to inkscape mailing list, think is not problem to you.

Inkscape .msi installer
by the Adib 12 Nov '12

12 Nov '12

Hello, as announced I want to present the first stage of creating win32 installer. The installer can be found here: inkscape.msi http://ubuntuone.com/0pHUvyQO1m7tWCk4Ydoep4 !! 90MB !! screenshot of the components http://ubuntuone.com/0S2vP6KLu891CVMFK8tmaO inkscape.wxs wix source file http://ubuntuone.com/4wei7vaqtzSEJw6H9Ay4Ef files.wxs http://ubuntuone.com/6d7WibY70E0Yx9lSpRDyNS autogenerated by files.py script http://ubuntuone.com/30QvLD8fqA53GjcNKOJO71 To create the msi I use two batch files wixenv.bat http://ubuntuone.com/4HzKeKzmMdz0yG3QA9CmcU to setup environment variables install.bat http://ubuntuone.com/0RqrCJj2d1cOOhiRrxX5fL to create and test the installer. Still there is a wide room for housekeeping and polishing but I wanted to let you know and if possible you all could provide some feedback. Currently some functions are missing: - decide user or global scope (my office laptop prevented me to install because of policy settings) - localized installer - register .svg files to open with inkscape The setup is very large compared to the NSIS setup because of loose compression. I fear I can not do something about that. As I understand the wix system works it is not possible to mixup options like localisation and shared files as examples and tutorials. So even you decide only go with english it will install translated examples and stuff. I have not tested on WIN7. However the installer registers all files and uninstall only those (but also possibly changed files) files being installed. Is it requested to have Inkscape in different versions (0.48 and 0.49) on one machine? have fun, Adib. --

Bug in PDF+LaTeX, how can I send a patch?
by M H 12 Nov '12

12 Nov '12

Dear all, I found a small bug in the PDF+LaTeX export module. In the generated tex-file that contains the object placement information for latex a few comment character at line ends are missing. This causes some funny misalignment effects if the final pdf with superimposed text is wrapped into other latex-command. Sometimes LaTeX requires to know where a line ends, otherwise undesired spacing is created. We have identified the lines with missing comment characters '%' here: http://tex.stackexchange.com/questions/82080/pictures-from-inkscapes-pdflat… and I would not mind to fix this myself, but I can not find where the PDF+LaTeX module is located in the inkscape branch. If someone could please point me in the right direction, I'd appreciate it. Regards, Martin

Windows MSI installer
by the Adib 06 Nov '12

06 Nov '12

Hello all, I just want to tell that I am the half way done for an msi installer using wix. I will post this within one week. Currently I am not so familiar with the wix syntax. For the moment localization of the installer is not supported (but can be done). Using wix some important functionalities are built in: - uninstaller - distribution on network using microsoft tools Cheers, Adib. --
