Hi
All,
Here is my feedback
on the Style attributes document:
I can't speak for
other implementers, but exposing all those attributes in a DOM interface or
declarative animation is a lot of work. Why not try and narrow down the list? So
far, I just don't see how a good number of the attributes help us achieve our
list of requirements. I think some examples would help me a lot. Now this
is just off the top of my head, but I think that a number of suggested
animatable styles require a lot of development work (for our viewer). In the
table below, I list my own preference:

Isn't changing the pattern/hatch enough?
Just a
note. In my own personal opinion; I think I would dedicated resources to
transparency and animation along a path as oppose to the Style
attributes.
Feedback would be
appreciated.
Regards,
Benoit
