Re: FLASH: How do you make Gifs with clear sections?

Since PNGs with an Alpha channel can be up to twice as large as a bitmap

without the an alpha channel using GIFs can result in substantual file

size savings. GIFs don't use an alpha channel but use one (or more) of

the pallette colors to be transparent. Unfortunately, Flash only

recognizes the Gif 89a transparency if it is set for Index Zero, so you

must set the color you want to be transparent as the Zero Index color

(upper left color on the palette) before you export the GIF for use in

Flash.
