Remove white from around edges?

[rxsid]

Hi all,

I've greate a gif logo using Fireworks MX. It looks fine on a white background, but when it's over a colored background...there is white along the edges of the text as well as the images in the logo.
I've tried to change any white in the logo to transparent, but I'm not getting all of it. It makes it better by maybe 50%, but not completely gone. Apparently, feathering is supposed to work. I've tried a feathering setting of 10 to 200 and nothing works.

How can I remove the white around the edges?

Thanks!

You need to locate the anti-aliasing colors. I don't have Fireworks, but find a dialog with that word in it, and you'll be set

One of my websites logo's had this same problem, a strange white coating around most things in the image. What i did was, if you have photoshop, I took the gif and opened it back up, then used the Select Colour Range tool to highlight all the white and delete it, then when I saved the gif again and re-imported it (in my case, back into dreamweaver and the WWW), the white was gone and the image looked as it should.

The white halo effect your seeing is a result of anti-aliasing. As GIFs don't support any opacities other than 0 and 100 percent, the somewhat transparent parts of the image are given a level of the anti-aliasing color so it looks like it's blending into what background color you want. If the anti-aliasing color is the same color as the background you want the image to sit on, the halo will not be visible.

Of course, if you only have the GIF, you won't be able to change the anti-alias color. You'll have to do it manually like Antwan said.

Another trick is to use a mask. When you optimize and save the image of a .gif, you can choose transparent background and use a mask of a similiar background color that is on your website. Then the little white jaggies aren't noticable.

the info about the anti-aliasing colors is what helped. i did a little more looking around in Fireworks (which I'm no expert in) and was able to make the necessary changes to remove the white around the edges.

thanks for the replys!
