[linux-help] Re: Help with GIMP

[Jonathan Hall <jonhall@xxxxxxxxxxxx>]

If you're creating a transparant gif for a web page, for instance, and the
background is a solid color, the simplest way to do that is with transgif
(or is it called giftrans?)

Basically, you tell transgif what color should be the transparant background
(using the color index in the GIF file), and it dumps the modified gif to
stdout IIRC.

transgif -t 1 <input>.gif > <output>.gif

I think that's right... man transgif or just run it without any options and
it shows help, I think.

I usually use the eye-dropper tool (whatever it's technical name is) in GIMP
or some other graphics viewer/editor to determine the index value of the
color to make it transparant.

I believe GIMP has the ability to save directly as a transparant GIF... but
I'm not sure how, or it hasn't worked when i've tried.
