Regarding my prototype site,
http://tunderhill.members.winisp.net/inkml2svg, I've tested it on Chrome
and Safari on Mac and the top five browsers on Windows.  It was just bad
luck that when you tried to go there, my ISP was down.   Its back up now!

of SVG is that it support variable width strokes.   InkML that is encoded
with pen or touch pressure should render with wider or narrow strokes.
In my prototype, I tried drawing separate line segments with variable
widths, but in all browsers doing so defeats the nice antialiasing of the

The SVG files I attached before had a problem: there's a bug in Visio
where arrow heads on lines don't output correctly.   The problem is that

Great, thanks very much!  (You know me too well, providing the SVG files
as well...)

I couldn't get that to load (I'm on a Mac, so I didn't boot into Windows
yet).  I'm getting an HTTP Error 503: The service is unavailable.

Have you seen my inkml2svg script?
