I should also note that a BMP that is not to complicated (colors/curves)
that is traced performs great in flash as animated. But a fine line exists
between a BMP that's complicated or not. A complicated and traced BMP will
not only be a larger file than the original, a processor/video card will
require more resources to redraw it as it animates.

Things you can do that don't effect quality include reducing the number of
colors in the image. You'd be suprised that going from 256 colors to 64 or
even 32 colors perceptively changes the image none, but makes a much tidier
file for web distribution.

Animated BMPs, you know, photographic images, whether traced or not, is how
some of the coolest effects can be done in flash IMO. It's worth
experimenting with . . .

The degree in which a BMP must posterized and still look good/interesting as
well as animate well is an art unto itself.

But again . . .

There are no set rules for BMP's. Except Trial and Error.

thanks to everyone for their responses to my rotate and scale across
a tween question.

I've found that rotating to exactly 45 or 90 degrees cuts down on the
bitmap distortion (looks fine in it's rotated state). Scaling is fine
on the end frame as well (used pngs).

But the tween distorts terribly during rotation...so i've recommended
we don't rotate any of em.

cest la vie, eh?
