Re: .gif export sizes

[Colin Moock]

Thanks for following up jd.

I'd be very interested to hear any guidelines you can extrapolate from

your tests. 


It may help you to know that in most of my tests I used *only* Flash to

generate the vectors and text. No imported bitmaps, no imported art

from other programs. I didn't try building the same thing from scratch

in Fireworks, I just exported the gif from Flash, then took the

exported gif and saved it out from Fireworks. I did, however, do one

test where I redid the text in Fireworks. The size didn't vary much,

but (as I said before) the antialiasing was much nicer from Fireworks.


I guess the worst part is the increase in export sizes from Flash 2 to

Flash 3.


Let us know if you find anything!
