[Lib2geom-devel] New HLineSegment/VLineSegment classes and path.h splitting
by Marco 28 May '08

28 May '08

I splitted path.h in the following files: curve.h (abstract class Curve) sbasis-curve.h bezier-curve.h elliptical-arc.h path.h (class Path and iterators ) and path.cpp in curve-helpers.cpp (CurveHelpers::root_winding) path.cpp (all the previous methods) finally I added a curves.h file so defined: #include curve.h #include sbasis-curve.h #include bezier-curve.h #include elliptical-arc.h #include hvlinesegment.h path.h includes curves.h so existent code should have no problem. The HLineSegment and VLineSegment classes will be useful to represent directly "H" and "V" curves found in the svg path element. I committed all changes both to 2geom and Inkscape. Btw I needed to do a make clean before succeeding in building inkscape correctly, because at beginning CurveHelpers::root_winding was seen as defined more than once.

inkscape community site
by Frank Karlitschek 27 May '08

27 May '08

Hi guys, I'm running openDesktop.org, KDE-Look.org, GNOME-Look.org and other websites for Free software. I´m also a longtime inkscape user. I created lots of icons for KDE with inkscape. :-) I noticed that there is no real community site where Inkscape users and developers can share drawing, templates, scripts, fonts, screenshots, new ideas and other stuff. I know there is open clipart, but it lacks the social networking functionality and other stuff. So I created www.inkscapestuff.org . It is part of the openDesktop.org network. So if you have an account on GNOME-Look.org on any other website you can login. There is also a public api if you want to fetch and integrate the stuff into other websites or Inkscape. http://api.inkscapestuff.org I hope this is helpfull for you and the Inkscape users. What do you think? I you have ideas or suggestions how to improve the site please send me a mail. Cheers Frank -- Frank Karlitschek frank@...1981...

UI proposal: workspaces (art, chart, technical, kids)
by Valerie 27 May '08

27 May '08

Inkscape doesn't need this as much as some other graphics programs probably do (I'm mostly trying to push it for Krita), but since Inkscape is going to add technical drawing capabilities, it's as good a time to start considering this as ever: Workspaces would basically be a divide and conquer approach against excessive UI bloat. Basically, 1 workspace = one saved set of settings (including toolbox items and tool option settings). UI: in the top menu, you add a Workspace drop-down with the following possible entries: - General - Icons/logos - Art - Charts - Technical - Kids - anything else you can think of (comics, maps, whatever) Click on any entry to switch from one to another. Art for example will emphasize the Calligraphy tool (with eventually several settings possible and separate entries toolbox entries for the tweak tools, so you don't have to dig them up all the time). I'd also like to see a separate workspace for Composition when composition tools are created (the workspace would basically give you composition tools and a few basic drawing tools). In workspaces such as Charts, tool option settings will automatically switch to properties such as "disable scale stroke width." You could also implement hybrids of the shape and text tools so that when you click on the centre of a shape (say... rectangle), you can start typing and editing text directly, and the text will automatically align itself with the centre of the shape, and/or the shape automatically expands when necessary (options available). Normally, such a feature would add bloat to the UI, but within a specific workspace it'd Really save time since the user would no longer be forced to align all the time. Really, this could cut down chart drawing time by half. Technical drawing will emphasize technical tools while pushing back all the non-technical items. It may also have default grids and snap settings. Within each workspace, you can still add another of the existing tools. This could be done either via a "configure toolbox" button or within a "Configure workspace" entry in the workspace drop-down. There, you just tick the tools you want in your toolbox. Workspaces could also make one's life simpler when the following start to get implemented: - animation (I Really doubt most people want the animation features taking up screen real-estate most of the time) - collaborative online work environments and such? The difficulty, of course, lies in whether Inkscape has the architectural options necessary to save and switch settings in such a way. If possible though, it will decrease UI bloat while allowing easier access to certain tools depending on the task (like the sub-modes of the Tweak tool), and could eventually allow some workspaces to have features that would otherwise be bloat in others (timeline bar for animation, maybe mini-icon galleries for if those are needed, and the shape/text hybrids I've mentioned for a chart workspace).

Suggestion: Calligraphic presets - save and edit
by microUgly 26 May '08

26 May '08

Sorry if I'm raising a suggestion that has already be discussed. I've just tried out the calligraphic preset option in the May 22 Win32 snapshot. When you select a preset and make a change, instead of the preset selection jumping to "No preset" can the preset selection remain except with a "*" beside the name (i.e. Marker*)? This will make it easier to identify which preset you had been using before making a change. When you choose to save the changes, populate the "Profile name" (should that be changed to "preset name"?) with the select preset name so you can easily save over it. With these changes you could change "No preset" to "Default" and allow users to easily define their own default. In my work I'll probably create a few presets combinations such as "Slow thin" and "Fast fat" etc. But every drawing will be slightly different, and in some cases the same part of the same drawing might require tweaking of the settings. So being able to quickly tweak and save my presets would be an useful feature. -- View this message in context: http://www.nabble.com/Suggestion%3A-Calligraphic-presets---save-and-edit-tp… Sent from the Inkscape - Dev mailing list archive at Nabble.com.

SVG Fonts: current status
by Felipe Sanches 26 May '08

26 May '08

------ If you just wanted to see some SVGFonts rendering, stop reading, this is not ready yet... ------ I have been working on SVG Fonts and I have recently created a coupe of files (src/display/nr-svgfonts.{cpp,h}) to deal with cairo userfont feature (rendering). It is still incomplete code, of course. I am sending a patch attached to this email. It has several issues: * Still doesnt render at all :-P (but the cairo userfont callbacks seem to be called properly, so it is a matter of time&pacience to get it working) * The userfont callbacks are called only once for each glyph. It means cairo is caching my glyphs, which will be a problem when the user modifies them. * It deals with only one <font> declaration (should be extended to various svgfonts in a single document). * Currently I have been trying to test this code by calling cairo_set_font_face (ct, nr_svgfonts_get_user_font_face()); cairo_show_text (ct, "A!@A"); But I do not have a proper place to put this call. I have tried to call if from within nr-arena-render-glyphs.cpp, but it is probably wrong. * Our SVG fonts are not registered to the fontlister nor managed by pango yet. * We still depend on pango integration so that we can fed pango with our cairo_font_face_t* created by nr_svgfonts_get_user_font_face(). This would be integrated with the current pango code that exists in inkscape. * I also admit that I need to study a bit more about how inkscape handles units and how these are fed to cairo. Some units&coordinates in this patch are arbirary guesses. Also, this patch depends on linking inkscape to cairo development branch (git master) which has support for userfonts. That's one of the reasons why this has not been commited to svn yet. I don't want to branch, but I will do it if there's no other option. I would rather prefer to have --enable-svgfonts option in ./configure Can anybody help me with that? I have never done this kind of thing. cheers, Juca

Serious regression!
by Diederik van Lierop 26 May '08

26 May '08

Hi all, In current SVN I cannot do anything useful with paths! For example, when I draw a simple line then I notice things like this in the XML editor d = m 140,6.21105e+184 308.6,0 Similar things happen when trying to translate a node or a line. Things worked perfectly until maybe a few days ago. I just tested a previous build of may 15th, but that one works just fine. Is anyone else seeing this? Does this ring a bell for someone? BTW, I tested this at work on a XP machine. Diederik

Calligraphy Tool
by Fela Winkelmolen 25 May '08

25 May '08

Hi! I'm currently implementing a calligraphy tool, much like the one present in Inkscape, for Karbon as a Google Summer of Code project. I've heard rumors that there is a plan to rewrite the calligraphy tool of Inkscape, but I couldn't find anything in the ml archives about it. If I understood it correctly the main reason is to make it possible to edit the path in an easier way--actually making it possible to edit the path drawn instead of the final shape created by the tool. I've heard the idea seem to be to use pattern on path, but that doesn't seem to me to be very easy to get right, particularly becase in this case the "pattern" depends on the path. I would like to hear more about this, is there any concrete idea about how it would be implemented, or is it only a vague idea? Also, if you have any other kind of advice, please share! =) Thanks, - fela

memory usage
by Florian Lohoff 25 May '08

25 May '08

Hi, i am thinking of digging a bit into inkscape code concerning the memory usage. As some might know inkscape is used for rendering tiles for OpenStreetmap (Osmarender) or better InformationFreeway. I have seen inkscape regularly consuming up to 12GB (yes - twelve GIGABYTE) of memory to render a tile. Less complex tiles get away with 300-1200MByte of memory which also is a huge amount of memory. This memory issues reduces the number of machines capable of hosting the "tilesat home" client quite drastically (64bit Linux with 16GByte of ram). I have seen that there way a Memory track for the Google SOC 2006 to reduce the inkscapes memory - What has been the outcome to this? My first imagination is that probably the garbage collector does not kick in because of using inkscape in batch mode or somethin. I ran inscape with GC_LEAK set and found the GC running so its not an issue of not reclaimed memory.

<title> and <desc>
by Stephen Silver 25 May '08

25 May '08

I'm currently working on making the title and description fields in the Object Properties dialog work (bug 171024). SPObject already had some dummy member functions to get and set titles and descriptions, so I've turned these into working functions. But I see that there are also dummy non-member functions that are supposed to do the same thing. I could easily implement these using the member functions, but it seems like pointless clutter to have both member functions and non-member functions doing the same thing, so I'm tempted just to delete them (they are not used anywhere, except in the macros SP_OBJECT_DESCRIPTION and SP_OBJECT_TITLE, which are themselves unused). Is there any reason to keep the non-member functions? -- Stephen Silver

Bezier crash in SVN
by Josh Andler 24 May '08

24 May '08

On two different linux boxes, if I compile from current svn, any use of the pen/bezier tool crashes inkscape. Unfortunately, it seems like there may be stack corruption as the backtraces don't look very useful. Both boxes in question are running Ubuntu 8.04. Would someone else on linux confirm if they're having this problem? (yes, I have two separate boxes exhibiting it, but they're the same distro). Thanks, Josh

making inkscape xembeddable
by unknown＠example.com 23 May '08

23 May '08

Hello, I tried to make inkscape xembeddable with the following in main.cpp: int socket_id=atoi("67108897");//xargv[1]); Gtk::Plug w(socket_id); printf("plug id:%d socket_id:%d\n",w.get_id(),socket_id); main_instance.run(w); that is, I just tried to pass a Gtk::Plug initialized with a gtk_socket in another process to main_instance.run(). This doesnt work. Any hints as to why? The context is that I'm working on a patch to allow applications to be xembeddable in an emacs window. This works with other apps than my patched inkscape. The goal in this case is to provide an alternate command based gui for inkscape using emacs. -- Joakim Verona

Re: [Inkscape-devel] Accessing individual nodes in a path
by Bob Jamison 22 May '08

22 May '08

If you look at the SVG-DOM spec, instead of defining the nodes, they defines the path segments: http://www.w3.org/TR/SVG11/paths.html#DOMInterfaces SVGElement implements SVGAnimatedPathData, which has getPathSegList() and its variants. And the list holds the segments, each of the subtypes of which has the node data. bob -----Original Message----- >From: Maximilian Albert <Anhalter42@...173...> >Sent: May 21, 2008 9:20 AM >To: inkscape <inkscape-devel(a)lists.sourceforge.net> >Subject: [Inkscape-devel] Accessing individual nodes in a path > >Hi, > >for a couple of applications I have in mind it would be very desirable >if one was able to access and refer to individual nodes in a path in a >way that is unaffected by future insertion/deletion of other nodes (in >much the same way as accessing the members of a linked list is >unaffected by insertion/deletion of other elements). > >How easy would it be to achieve this, especially considering the change >of path representations to 2geom?

Path intersection, union, difference code
by Frederich, Eric P21322 21 May '08

21 May '08

Hey guys, I'm writing a program that generates SVGs. I realized how big of a pain paths are. Right now I am basically just doing straight lines. The curves that I do have are radii and they're all 90 degree semi circles. Those were a pain too, luckily I stumbled upon http://www.whizkidtech.redprince.net/bezier/circle/ and I can create them in my paths. Anyway, I'm at the point where I need to start doing some more complicated things. I can do these things easily in Inkscape but I'm finding it difficult to generate the path data directly. I am wondering where in the source of Inkscape I can find the routines that do the intersection, union, and difference of paths so that I can incorporate it into my code. Thanks, ~Eric

Accessing individual nodes in a path
by Maximilian Albert 21 May '08

21 May '08

Hi, for a couple of applications I have in mind it would be very desirable if one was able to access and refer to individual nodes in a path in a way that is unaffected by future insertion/deletion of other nodes (in much the same way as accessing the members of a linked list is unaffected by insertion/deletion of other elements). How easy would it be to achieve this, especially considering the change of path representations to 2geom? What would be necessary to implement it? Can this be easily integrated into existing path representations? Max

If so, why isnt it storing an absolute path to the jpg file? Also, I guess, absolute paths in xlink:href are evil, since they often only work on the drawing author computer :-P
