The docs have info on dropping out the 1-bit transparent pixels of a

GIF-like file. If you're instead talking about gradual transparency, then

you've presumably got an alpha channel, and the documentation describes PNG

as the format, then.


Tip: Photoshop uses "premultiplied" alpha, and so you might see some white

halos on gradual transparency of some images. If you use Fireworks to

create your 32-bit PNG then you'll have nice, "straight" alpha and won't

usually need to pay attention to matting colors.


Be advised, though, that a 32-bit PNG contains about four times as much

data as an 8-bit GIF. Both are subject to interpolation when resized. I

generally use bitmaps for texturing, myself. (There are certainly sites

that have thought through bitmaps and used them successfully, though.)
