Re: [svg-developers] open svg files in opera

My problem is that the default setting of opera when opening a file is to display only html files. Of course, one can unrole the menu of file extensions and choose SVG or all files but it's quite annoying to do it every single time. I'd suggest asking the same question in the my.opera.com forums[1]. Usually I dragdrop svg files on Opera to open them, or use directory listings and search for .svg (if you have enabled single-key shortcuts just press comma and then type what you want to search for). Do you know how to change the setting of opera for it to automatically offer the possibility of opening svg files or even all files? I don't think there's a pref setting for which file-extension filter is used by default, but I could be wrong. And I would be surprised if there wasn't a way to modify the install of Opera to change the default order by some other means, such as editing a config file manually.

[svg-developers] Re: Things I'd program if I had the time
+ An SVG viewer Java applet, which just checks whether Apache Batik [10] is available to use for displaying an SVG document, and if it isn't then it should direct the user to instructions for downloading Batik and adding its location to the class path[11]. The applet itself would be rather small. It could be used as fallback content for non SVG enabled browsers (of course, this could be added automatically by the XHTML deploy script mentioned above). One could also use the applet as the only method for presenting SVGs to the user. This way one wouldn't have to deal with browser specific limitations in SVG support. Batik would be the only implementation in which the content needs to work. Even non-standard extensions, implemented in additional classes stored on the server, could be used, but that would probably be more complicated to handle, and would therefore not be supported by the first release version of the applet. I feel like I might also suffer from this lack of time disease! ;-D Actually, I've been idle studying the possibility of creating a Batik-based applet viewer, although it's not quite there yet (both due to the applet itself and to some Batik interoperability things that need to be improved first). Of course I'll post whenever something useful is made available but, in the meantime, I'd like to share my current status regarding this. There seems to be demand for such feature [1] and supporting Java-enabled IE would surely help boosting SVG deployment. :-) Thanks for sharing, Helder Magalhães [1] http://www.w3.org/Graphics/SVG/IG/wiki/SVG_Plugin_for_IE#Use_of_the_Apache_Batik_toolkit - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

Re: [svg-developers] Re: Things I'd program if I had the time
One thing I've been curious about recently is whether Batik works on the Iced Tea JRE. This wouldn't affect the building of an applet viewer, but having the ability to bundle a JRE would be extremely important if one were to actually want to work on building a Batik-based SVG-viewer plugin.

[svg-developers] progressive drawing of path -- attempt to use clipPath
Andreas wrote: not sure I fully understand your requirement. Are you looking for a progressive drawing of a path geometry? If yes, you can do this by animating the stroke-dash of a path. Examples are provided: [1] and [2]. Yes; exactly what I was asking for. Pretty clever it is! Now I have a new question - consider the example at http://srufaculty.sru.edu/david.dailey/svg/unveilPath.svg (it uses SMIL so be sure to use a proper browser) I've simplified the basic example as much as I can, and am trying to animate the fill to follow the animation of the path. Clearly this is a kludge. However, what I did think of was the following: how about I stick a copy of the first half of the path (with its animated stroke-dash) inside a clipPath and then apply the clipPath to the original path. Then shouldn't the growth of the clipping region unveil the path as well as its fill, concurrently? Alas, it didn't work. From the spec [3] , we find that The raw geometry of each child element exclusive of rendering properties such as 'fill' http://www.w3.org/TR/SVG/painting.html#FillProperty , 'stroke' http://www.w3.org/TR/SVG/painting.html#StrokeProperty , 'stroke-width' http://www.w3.org/TR/SVG/painting.html#StrokeWidthProperty within a 'clipPath' conceptually defines a 1-bit mask (with the possible exception of anti-aliasing along the edge of the geometry) which represents the silhouette of the graphics associated with that element. This means that the animation of the rendering properties won't affect the footprint of an object inside a clipPath. Too bad. It looks like it's back to script for this. Ultimately I want to simulate the growth of a live tree (the kind with bark) and progressive drawing seemed like a useful approach. Is there a reason (other than cross-browser consistency) that the spec limits the footprint to the raw geometry? An object's silhouette as modified by stroke properties could be quite handy for exactly this purpose.

Have you looked into HTML+TIME Animation? http://msdn2.microsoft.com/en-us/library/ms533113.aspx It can also be used to animate style properties of VML elements (I've tested that), and since position, dimensions, and rotation are determined by style properties in VML this could allow some declarative animation in SVG to be converted.
