Can anybody point me to something like the Napkin LF
(http://napkinlaf.sourceforge.net/) done with SVG? I found a site that
generates UML sequence diagrams in various formats (not SVG) that does a type
of napkin LF (http://www.websequencediagrams.com/).
Thanks.
Using your link, I get JScript runtime error: 'this.mapSVG' is null or not an
object line:73, column 1 on reload.
That is on Windows XP, IE 6, with ASVG 3.03.
Not that I know what's causing it. Just thought I'd report it since others
cannot reproduce it.
FWIW, it looks pretty good with Google

You can set the stroke-width to the inverse of the

I think that you can get the effect you are trying to

SVG is just XML, so you are looking for an XML parser for C++. Google for xml

You can use a stylesheet that can be applied to multiple files. See
http://www.w3.org/TR/SVG/styling.html for an example. There is also an example
on that page, so you can make sure that it works for your environment. You
can't reuse styles in a stylesheet, as Jerome pointed out.
Jerome,
You can pan or zoom any element or group of elements. You can use something
like this in you Up() function, which I assume is event driven, to pan the
group of objects in the y direction:
obj=SVGDoc.getElementById(to-be-updated);
obj.setAttribute('transform','translate(0,' + change + ')';
You can pan as much as you want in any direction. If you look at your code I
think that you'll see that you aren't updating the translate variable
correctly. Put in alert() functions to display the translate variable before
and after you modify it; you'll see what I mean.
There are too many elements, making it unable to display, or very slow.
I was able to display 365,000 rects in batik and deer park (mozilla nightly
build with SVG enabled). It takes a long time to display, and screen updates
were very slow. It would no be usable.
