Am I wrong or missing something. I don't figure how to rasterize or export to bitmap only the cliped or masked area of a drawing. It always export the whole drawing. rev 11761 and other devels before. ivan

Save window geometry options in preferences
by Staffan Einarsson 28 Oct '12

28 Oct '12

Hi, I have been working with Inkscape in the past on a spare-time single-user basis. Now I started to look into using it for producing graphics in a collaborative environment and I ran into some problems. I'm looking at SVG because it is a standardized and flexible format. More to the point, it is text-based, which makes it so much easier to work with in terms of version control and simultaneous editing. The following discussion concerns Inkscape 0.48 on Windows. I noticed that my window layout, among other things, is being saved by default to the Inkscape SVG file. As, this is not a good thing when collaborating with other people, because everyone will mess up each others environment, I tried to turn it off in the Preferences. Then I couldn't get the "Windows -> Remember and use last window's geometry" option to work. When I turned it on, the window layout was still being saved to (and loaded from) the SVG file. Only when I choose the "Don't save the window geometry" option was the saving omitted from the file. This seems like a bug, and I couldn't find it in the issue tracker. I would like to discuss some solutions. One alternative is of course to make the current intended behavior work. This means that the "Remember and use last window's geometry" option should only save window layout info to user preferences, not to the file. An alternative that I think makes more sense is to still save the layout along with each file (because different projects motivates different layouts), but to save them in a separate user settings file. So if I saved my foo.svg I would also get a foo.svg.user, or something similar. Actually I think all the attributes in the sodipodi:namedview tag could be moved out from the SVG to the user settings file, because they are all related to the work environment, and would differ from user to user. The benefit of having two files is that the user file can be excluded from version control and be kept locally for each user, while only committing changes to the actual SVG image. Also, at the moment when using the option to save layout to the SVG file, changes to the layout does not mark the file as dirty. If I just change the window layout and press Save, nothing will be saved. I have to modify an object to make the file save-able for the layout to be saved. What do you guys think? Kind regards, -- Staffan Einarsson

Help testing SpiroLive
by Jabiertxo Arraiza Cenoz 27 Oct '12

27 Oct '12

Hi all. I'd like to ask you something. I created a branch of Inkscape to show "Spiro" while of drawing with the "pen". I would like you to give me your test and impressions, with the intention of proposing to introduce in inkscape. The branch is here: https://code.launchpad.net/~jabiertxof/inkscape/SpiroLive Thanks in advance and excuse my English.

New branch "-" simbol
by Jabiertxo Arraiza Cenoz 27 Oct '12

27 Oct '12

Hi. Im starting whith a branch for made B-Splines in inkscape. I have a problem compiling effects-cpp whith the "-" symbol. I check another Live Effects whith the same problem but im not sure about what is better. The name of the lpe is "B-Spline" but i want to ask whats better use 2 kinds of name (ex- "B-Spline" && "B_Spline") or use another name like "B Spline" && "B_Spline" or "BSpline" && "BSpline". Its a basic cuestion but i want to start ok. Finaly the cuestion are: What is better? * BSpline * B-Spline -problem compiling * B Spline Thanks and sorry for my bad english.

Re: [Inkscape-devel] Coefficients in FeColorMatrix, Fecomposite (limits, behaviour with neg val...)

> Cairo does the job fairly fast and you can set up multithreading in Edit/Preferences/Rendering/ I set the number of threads to 8 some days ago and I was a bit disappointed to see no enhancement at reboot. Just forgot I set inkscape preferences file to be read-only. Fool. Now it's better :) > Basically, each filter primitive constitutes a very expensive copy of the image. Yes know that. By the way, is there any chart about CPU consumption of each primitive ? (say for 1px wide). I would say lighting is the more CPU intensive, am I right ? >(if you're really interested, I'd recommend searching the archives). Is there any other way to search the archives than the sourceforge web interface ? The UI is crappy and inefficient (or maybe I missed something obvious) > all these problems are non-trivial to solve. Maybe it lacks at least one trivial optimisation. It looks like Inkscape render all primitives even if they're not "connected" to output. Exemple Create new filter. Add a Fill => rendering is lightning fast. Add 50 blur stages with a 100 px radius => it should be slower or way slower or ssslllloooowwwweeerrr (depending on your hardware). Logical. Move the fill at the last stage of pipeline. Still slow. It shouldn't. It's uneccesary to compute any blur stage at all. You'll ask why the hell do you add unnecessary stages ? When I design filter I often ask myself "what will it looks like if I disconnect these block of 5 primitives " As adding primitive is very slow with the current interface (*) I don't remove the block but I only disconnect it. As time goes by there are more and more dead blocks and I sometimes forget to remove them. I'm not 100% sure but I think I saw dead blocks in filters fitting with inkscape * any news about this blueprint ? http://wiki.inkscape.org/wiki/index.php/SpecFilterEditorUI No ? So I should think about buying a new monitor. Mine (1920*1200) is too small for designing filters. lol

Compiling on Windows 7 x64
by Arshdeep Singh 27 Oct '12

27 Oct '12

Hello, Unfortunately, there is some problem with the build file or something wrong with the inkscape.exe. I have tried compiling on another machine on Windows 7 x64 only to face the same problem. The problem is: the build process completes successfully without errors but the inkscape.exe runs for a few seconds (seen in the task manager) and then quits. No windows opening, no send error report messages. Just a 'inkscape.exe' process in the task manager. Compiled by following the below page word to word: http://wiki.inkscape.org/wiki/index.php/Compiling_Inkscape_on_Windows Compiler: TDM-GCC 4.7.1 Mingw32 bit edition and not the experimental 32 cum 64 bit one. I am new to development and can't seem to debug the .exe properly using gdb.exe. Please, can someone look into this. -- Arshdeep Singh

Coefficients in FeColorMatrix, Fecomposite (limits, behaviour with neg val...)
by pennec victor 26 Oct '12

26 Oct '12

Hi, I think I'll be a little bit off topic but I don't know where to ask (my question about svg on inkscapeforum are left unanswered) Can someone point me to reference papers (or friendly forum) about coefficients in FeColorMatrix, Fecomposite ? Something that could answer the following questions : What are safe values ? For exemple inkscape UI allows x10 for k1,k2,k3,k4 in FeComposite, can I push to 255 ? 256 ? 1000000 ? I don't see anything in SVG spec about max values for those coeffs. What about neg values ? When does clipping occur ? Particularly for k4. What is the effect of a <100% opacity source or dest ? (On clipping for exemple) I try to port svg2 PorterDuff operations in svg 1 and I often get strange results (to me) with inkscape. Is there some known bugs in rendering fecomposite with neg values in inkscape ? Thx. V. Bonus question : why is inkscape so slow at rendering filters ? ;)

Setting Up in Eclipse-CDT
by Arshdeep Singh 26 Oct '12

26 Oct '12

I intend to use Eclipse-CDT for working around the source code to understand things. If anyone can help me with it ? I import it. The C/C++ Code ananlysis results in lot of errors/warnings. I was wishing I code jump b/w linked files like we do for smaller projects in IDEs similar to Eclipse. Is something of that sort possible ? -- Arshdeep Singh Third Year, Computer Engineering Delhi Technological University Ph: +91-9654115614
