Coding conventions
by unknown＠example.com 22 Dec '03

22 Dec '03

Greetings, So, what sort of coding conventions do people want to adopt? I'm not really a C++ coder so I wont offer up too many suggestions, but I do intend on doing what I can to 'help' developers follow the decided upon conventions by creating Emacs and Vim modelines for the source files...unless someone has a good argument against doing that. At any rate, the only thing that I think is important is 'no tabs'...anyone care to suggest/discuss/argue-without-starting-a-war other conventions (this would include filename schemes for C++ as mentioned in the booleans thread)? *g* -Tom

PathEstimation
by Info Sylvax 22 Dec '03

22 Dec '03

hello, as a graphic designer, I am used to work with Adobe Illustrator and the PathEstimation features built in are very important for me. but I work under Linux now... When will the PathEstimation feature be available in Inkscape? For me, it is the most important feature (for the design of logotypes, arabesques... ) thanks a lot, sylvain

Re: [Inkscape-devel] spiral???

>The argument was made on Jabber that this was a pretty useless tool. We >couldn't recall instances that it had been used or heard from users that >were using it for anything more than curiousity. It probably would have >been good to mention this on the mailing list before removing the >feature; I suppose the thinking was that probably nobody cared one way >or the other. It is very strange reasoning!!! I STRONGLY DISAGREE. Sorry guys but we represent a very small share of the program's users, and even smaller of its potential users, both quantitatively (in number) and qualitatively (in not being professional designers). We should not take any serious feature decisions without as wide discussion as possible, and especially when we REMOVE something. Jabber is fine for quickly discussing small things, but this is a serious change which requires a balanced, slow, thorough discission. Jabber is not suited for this kind of discussions. Lauris did not invent this tool too; he copied it from other vector editors. Why do you think you better understand the needs of artists than, for example, creators of Macromedia Freehand (among others) which has the spiral tool??? >Does anyone use the spiral shape for anything? Hell YES, if only to amuse my 5 y.o. daughter! She will be BITTERLY disappointer by your decision. And seriously, I once spent an hour in Xara drawing a spiral by hand for one of my designs (Xara does not have a spiral tool), and it turned out to be so difficult that I quit, launched Freehand, created a spiral there, exported into EPS and then imported into Xara. So for me, the Inkscape's spiral tool is one of its very real advantages over Xara. I even mentioned it as such just a couple days ago to my wife, when she asked what was that new drawing tool I'm spending my time with recently! Even all that aside, how do you feel killing a feature which has almost 1000 lines of code, is well thought out, complete and convenient? There's simply no limitations to the kinds of spirals it can create - don't you appreciate that? Yes it has a bug, but show me a tool which has none! Were you seriously planning to add to the release notes, for example, "Answering many requests from impatient users, we finally managed to remove one the biggest Sodipodi's annoyances, the spiral tool?" Come on! It's just beyond me what kind of reasoning might lead to a decision like that. >Perhaps since we're not too crowded for space yet, and since the bug now >has a solution, that it would be prudent to let the spiral tool remain >until Nathan has a replacement for it? Yes, and only if that replacement is a strict superset. Sorry for sounding harsh, but this desicion really appalled me. I hope I convinced you to revert this decision, and moreover I hope you don't take decisions that suddenly kill almost a thousand lines of good code without a serious reason and a good discussion. _________________________________________________________________ STOP MORE SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=dept/bcomm&pgmarket=en-ca&RU=http%3a%2f%2fjoin.ms…

Hi, I tested your dnd patch but I don't seem to be able to make it work. If I type in some SVG in your test program and drag it into inkscape, no object appears on the canvas, but there is a new empty <g> in the XML editor. If I type <text>abc</text>, after dragging it becomed <g id="123">abc</g>. _________________________________________________________________ Add photos to your messages with MSN 8.

[Fwd: [Scribus] Inkscape, vector graphics]

22 Dec '03

-----Forwarded Message----- From: Magic Page <magicpage91@...127...> To: Scirbus List <scribus@...119...> Subject: [Scribus] Inkscape, vector graphics Date: Sun, 21 Dec 2003 20:00:16 -0500 Hi all, Not sure if many here are aware of the new program available for creating and handling SVG graphics. Inkscape is branching off from Sodipodi with a clear road map and I believe, a brighter future for a vectors grapic program for Linux. It already is impressive with the user interface and, I think, much easier and nicer to use because of that fact alone. Peter, of Scribus fame, turned me onto it just recently. I decided after compiling it, that I should make a real rpm available to other SuSE 9.0 users. I have created a RPM for SuSE 9.0 and passed it along to the Inkspace developers to include on their download site. The src.rpm is there also, so other linux distro users might be able to alter the spec file enough to use on their systems. SuSE is now putting all their Gnome programs in /opt/gnome, in an effort to more closely adhere to the LSB. I don't think Gnome is located in the same location for other distros. Anyway, give it a look and see if you don't like the changes as much as I did. It still gives you all the Sodipodi features, plus a few more and expect many more after the new year!

If I open "../filename.svg", the resulting "absolute" pathname will have ".." in the middle. Which is why I was asking if there exists a smart absolute path function that normalizes paths.

Proposal for New Subsystem Architecture (and Namespaces)
by Bryce Harrington 21 Dec '03

21 Dec '03

As part of the C++-ification, we need to introduce namespaces. In addition, we wish to reorganize the codebase to suit our longer term architectural plans, such as conversion to Cairo, Pango, and Gtkmm, introduction of our API and modular extension system, and provision to the community of an SVG Canvas. Here is a proposal for a new architecture that incorporates these elements. It also shows how to map from the current architecture. This is presented as a proposal to spark discussion, and will be updated with any feedback you provide. Please ask questions of anything that is unclear. Once we have a rough concensus on it, we will formalize it and can proceed with the work. I've also posted this to Wiki as "SubsystemReachitecture" if you'd prefer to comment upon or work on the document there. Bryce == Subsystems Summary == Namespace Link Audience Lib Name Directory Inkscape::Document C++ Internal libinkdoc src/document Inkscape::Extension C++ Internal libinkext src/extension Inkscape::UI C++ Internal libinkui src/ui/ Inkscape::UI::Dialogs C++ Internal libinkuidlg src/ui/dialogs Inkscape::UI::Widgets C++ Internal libinkuiwdg src/ui/widgets SVG::Canvas C/C++ Community libsvgcanvas src/svgcanvas SVG::DOM C/C++ Community libsvgdom src/svgdom Cairo C (dep) libcairo (external) Pango C (dep) libpango (external) == Descriptions of Proposed Subsystems == Inkscape::Document - This is a high level wrapper for the application's document model, and basically just subclasses SVG::DOM, adding some Inkscape-specific aspects. Inkscape::Extension - This namespace encapsulates the various mechanisms for extending the Inkscape application, including import/export mechanisms, GUI plugins, stdin/stdout programs, language bindings, etc. Inkscape::UI - Namespace for Inkscape-specific User Interface elements, including view & controller aspects. Inkscape::UI::Dialogs - dialogs for Inkscape Inkscape::UI::Widgets - widgets that are particular to Inkscape; if they seem to be of general use, they will be migrated into a separate library to share with other applications in a more general fashion. SVG::Canvas - A distinct deliverable Inkscape provides to the Open Source community for implementing an SVG-based drawing surface, for use in other applications. Initially will be made up of similar subsystems shared with Inkscape but be a separate package, but ultimately should be a packaged dependency of Inkscape. SVG::DOM - This is a Document Object Model for SVG documents. It is the key dependency for SVG::Canvas, and thus is also something Inkscape provides externally to the Open Source community. Internally, it is implemented as a C++ class hierarchy, but externally can be linked to using either C or C++ style linkage. The externally presented API would be standard DOM. Cairo - Switching to Cairo will occur late in the rearchitecturing process. We need to ensure Cairo provides the capabilities already present in libnr. Completing other areas of rearchitecting will help get the codebase organized for conversion of it to Cairo, without taking undue risk in adopting a different underlying renderer. Pango - Conversion to Pango from libnrtype may be worth doing earlier than Cairo since the existing text system lacks many needed features, however this will need to be researched in more depth to determine the feasibility and cost/benefit. Unless a clear benefit is identified to performing the change early, we should conduct the change along with the Cairoification. == Rearchitecturing Translation Map == Existing Proposed GUI Dialogs --> Inkscape::UI::Dialogs Widgets --> Inkscape::UI::Widgets, GtkDrawmm XML Editor --> Inkscape::UI::Dialogs View --> Inkscape::UI SPAction --> Inkscape::UI verbs --> Inkscape::UI shortcuts --> Inkscape::UI SVG DOM --> Inkscape::Document, libsvgdom SVG Canvas --> libvgcanvas Module --> Inkscape::Module Display --> Cairo libnr --> Cairo libnrtype --> Pango SPSVGView --> SVG::Canvas SPSVGViewWidget --> SVG::Canvas src/svg/* --> eliminate

saving views
by bulia byak 21 Dec '03

21 Dec '03

There's a sodipodi:namedview element in each SVG file saved, but it's empty. Is it right to assume that it was supposed to store the contents of the SPNamedView object of the document's desktop? If so, why it's empty - not implemented yet, or disabled? I propose to enable/implement it, and additionally, to extend SPNamedView with these fields: - zoom level and visible part of the canvas - window width/height and maximized status so that these settings could also be restored when the document is opened. Besides, the window size of the last closed document is saved into preferences, so the new empty document created next time will use them. (I'm so tired of the 400x400 default window!) Also, what about storing the absolute file name in SPDocument, as I proposed some time ago? Can anyone suggest a function for creating absolute name? _________________________________________________________________ Help STOP SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=dept/bcomm&pgmarket=en-ca&RU=http%3a%2f%2fjoin.ms…
