SVG Linking
by NAGY Endre 23 Nov '04

23 Nov '04

Greeetings I attempted to invoke the example in S17.1 of the SVG 1.1 specification in inkscape. This deals with "Linking out" of SVG content.The relevent part of this is <a xlink:href="http://www.w3.org"> <ellipse cx="2.5" cy="1.5" rx="2" ry="1" fill="red" /> </a> When invoking the example in InternetExplorer, the affect of clicking on the ellipse is to bring up W3's web page. I have not found a way of achieving this in inkscape. The relevent parts of the spec are 1. "SVG 1.0 only requires that user agents support XLink's notion of simple links." 2. "By activating these links (by clicking with the mouse, through keyboard input, voice commands, etc.), users may visit these resources." 3. "If the above SVG file is viewed by a user agent that supports both SVG and HTML, then clicking on the ellipse will cause the current window or frame to be replaced by the W3C home page." WRT 1, does inkscape meet this requirement WRT 2, MouseClicking events in inkscape are trapped for the puposes of the selector tool (I dont know how to turn of all tools). How can I activate the link WRT 3, My purposes are not the rendering of HTML but rather the invocation of a program. Does inkscape support this and how.

Feature Freeze for Inkscape 0.40 Release
by Bryce Harrington 22 Nov '04

22 Nov '04

It's time to start making the final push towards getting the release out the door. Here's the plan: Feature Freeze Phase: * Starts at End of the Day, Sunday, 11/21 * All feature development work ceases * Last pass through bug tracker for show stopper bugs * Last chance to submit tutorials and translations Hard Freeze Day: * All codebase activity stops for one day * Conduct final QA testing * Unless a show stopper is found, establish Release Branch * If show stoppers are found by end of day, go back to Feature Freeze Release Branch: * Verify AUTHORS, version number, release notes, etc. * Only intended for last minute cleanup * Remember to merge bug fixes back to main branch too * Announce Inkscape-0.40 final tarball to packagers * Create packages and post to SourceForge Release PR: * Update Freshmeat page * Post announcement of release to news sites, blogs, etc. http://inkscape.org/cgi-bin/wiki.pl?AnnouncingReleases * Notify distro vendors of new release availability How's that sound?

Some of it is going to have to be built independently. Sodipodi has a lot of deep architectural issues that need fixing; I don't think you would find it a good choice. Inkscape, in turn, inherited the same deficiencies and we're far from getting them all fixed yet. It also uses C++ and has some additional dependencies that might be undesirable for a more general library. I think the biggest thing Inkscape can bring to the table up front is architectural "lessons learned". If you want dynamic HTML (by which I assume you mean DOM), my feeling is you'll need to do something similar to what Sodipodi and Inkscape do: we have a pre-chewed "semantic" layer a bit like librsvg's, and then a raw XML/CSS abstract syntax tree underneath it, with protocols for synchronizing changes between the two. I hate reinventing wheels, though. What I hope is that we can take designs prototyped and tested in Inkscape, contribute them to cairo/f.d.o as components of more portable C libraries, and adopt those libraries ourselves to the extent practical. Sort of peeling layers off the bottom as we go, I guess. > I'd like to see a good "standard" retained-mode API built on top of > cairo.

My impression from lurking on Rosegarden lists and those of other KDE projects is that the state of the generic QT canvas isn't much better. You know, actually, it's almost like there's a curse on general-purpose canvas libraries... It might be helpful to examine why such projects seem to keep failing. I have a feeling mistakes in that area are easy to repeat. > As for making this portable, (ie. for Gnome and KDE), I don't know if > it should talk to one of the existing event-loop integration projects, > or if it should export its own hooks for plugging in an event loop, > (ie. perhaps libevent compatible or something). Someone who better > knows the toolkits and integration projects should be consulted there. Based on my experiences with Inkscape and Sodipodi, trying to treat every node in the display graph as a "mini-widget" with event dispatching is a mistake for broad and deep graphs like those that would correspond to many complex SVG documents. The important primitives to have in a retained-mode graphics API for graphical interactivity seem to be: * find the first descendant of a specified node matching a predicate (given as a closure), maybe with a choice of traversal strategies * primitives for determining whether a node overlaps with a given shape, maybe with optimized versions for testing against a point+tolerance radius, and against a bounding rectangle And then you can readily build "mini-widgets" on top of that if need be (potentially as a higher-level library), but you aren't forced to deal with the whole display graph that way. > In the meantime, has anyone played with cairo-based rendering for > inkscape? It shouldn't be too hard to get going, (for example, the > Scribus guys said they got something working in just one weekend last > week). Me, kind of. I've been experimenting with it a bit offline, and plan to work on it more earnestly during the 0.41 development cycle. One of the big hurdles is that it would need to work on Win32. As far as I know there is no Win32 GDI surface type, and it's not obvious how to get at the in-memory buffer of a Cairo image surface. Maybe some of the Win32 Inkscape developers could help with that, though (anyone interested?). -mental

fake small caps
by David Christian Berg 21 Nov '04

21 Nov '04

When a font doesn't have real small caps, they are the normal capitals scaled to 70% of the original hight or the such. Now this way they are too thin and don't look all that good. I wonder what the result would be like, if you trace a letter with an outline that varies it's thickness with the slope of the outline. Ranging from 0 thicknes for horizontal to 100% thickness (how many pts that are is adjustable) for vertical lines. I have no clue, it that works, but I think it might look quite OK. It's properbly not svg complient at all :( I'll propose this to the scribus list as well. David

NEW: changes keyboard selection commands
by bulia byak 20 Nov '04

20 Nov '04

I don't really know how the keyboard selection commands should best behave with respect to layers/lockedness/hiddenness, so I decided to make this configurable. Now there's a "Selecting" tab in Preferences which has three checkboxes that affect "Select all" (Ctrl+Shift+A) as well as selecting by Tab/Shift+Tab: - select only in current layer - ignore hidden objects - ignore locked objects By default all three are on, which is the most natural setting, but it's different from the behavior in the past and may not be the most convenient. Experiement and report which works best for you. Now only the Find dialog remains to be made layer/lock/hide-aware.

Layers dialog
by Bryce Harrington 20 Nov '04

20 Nov '04

Mental, I've got most of the layer rename dialog thingee set up. Could you put the code needed to rename a layer into the apply() routine in layer-properties.cpp? Bryce
