And as a follow up get the source code for Batik. I think it uses a Java version of the formulas to do the Java DrawArc command so it might be exactly what you are looking for. --- In svg-developers@yahoogroups.com, "bruce" wrote: > > For #2 (and maybe #3) see: > http://www.w3.org/TR/SVG/implnote.html#ArcImplementationNotes > > > --- In svg-developers@yahoogroups.com, "tushar0711" wrote: > > > > > > Hello All, > > > > I'm developing basic SVG Viewer using .Net GDI+.

Love it! But what if there are two cars and they cross under and over a bridge at the same time? You will need an extra "car" to make sure it is over the top of the bridge.

[svg-developers] Re: highway construction
Great! I wonder if the multi speed problem can be solved by having separate animations and start one when the previous ones ends i.e. linking. Then the key times go from 0 to 1 and the durations can be speed dependent. Of course when one car passes another all bets are off...

[svg-developers] Re: fun but buggy -- gears
Here is another interesting animation in the same vein. It shows two sliding blocks, one moving horizontally and the other moving vertically. A rod is pined to the centers of the two blocks. When this is done the motion of the ends of the rod traces ellipses. The following works in IE/ASV, FF4, WebKit, and Opera but interestingly does not work in Batik. http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd"; [ ]> http://www.w3.org/2000/svg"; > - The really strange thing is an early version of this file. I thought it would be simple to replicate the code for one block and rotate it by 90 degrees to get the second block. It didn't work but rotating it 180 degrees did (in Chrome where I was testing). When I thought I was done, I checked in FF4 - same result. In Opera, I got radically different results. IE/ASV showed the same as Opera. I believe Opera and ASV have the behavior correctly as I coded it. Again Batik does not show the rod correctly but shows the blocks as ASV and Opera. Any idea why FF4 and WebKit show the same but different display? http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd"; [ ]> http://www.w3.org/2000/svg"; > --- Bruce - To unsubscribe send a message to: svg-developers-unsubscr...@yahoogroups.com -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" Yahoo!

[svg-developers] Re: normalizedPathSegList
Are you looking for:
http://www.w3.org/TR/SVG/implnote.html#ArcParameterizationAlternatives
If it is then a conversion routine written in JAVA is:
ExtendedGeneralPath.java
in the Batik source. I wrote one in JavaScript based on it.

(I work for Opera, by the way!) You'll find very good support for SVG in our browser. BTW@ a couple of typos: "fathers" and "grandfathers" need apostrophes: "Father's" and "grandfather's".

It would be really helpful if you could let me have a list of which bits of the SVG you want to use are supported badly by Opera 11, so I can try to make sure that they're addressed by the next release, if you wouldn't mind.
