(keitai-l) Re: SVG == Scaleable Vector Graphics

I think the cool interactive stuff that is done with SVG is all done
in JavaScript at the moment, so you would need JavaScript to
run on the phones as well. Or some other scripting language.
The SVG interactive animations do many things by having the Javascript
directly manipulate the parsed SVG XML structure (i.e., the DOM tree), which
is strange and counter-intuitive but very powerful. It's like the old-fashioned
vector displays on computers which used a display-list to refresh the display.

I don't full SVG is practical in a phone yet. Maybe some lightweight Java 
API  interface
to an SVG subset? I know several different people or companies who
  are writing  lightweight SVG-like libraries for
sending vector animations to the iAppli or
MIDP platform (including myself :-) ).

There is a standard gnu-zip format for compressing SVG files, but I dont
know if that is as optimal as some kind of binary standard (which would
kind of defeat one of the selling points of SVG, it's easy to debug as
XML text).
