Transparency for a sprite sheet
Hi All,

New to the forum!

I have a PNG of sprites similar to this:

I want to change the background color to a transparent one. I've tried using Color to Alpha but that makes the sprites themselves partially transparent which is not what I want. My second attempt was to use the fuzzy select tool to select all of the white bits and remove them. This doesn't really work either because on a non white background each of the sprites has a few whiteish pixels around it's edge. So what I really want is a combination of the two, i.e. all of the white pixels are made completely transparent, and the whiteish pixels on the edge of each sprite are made partially transparent, but the sprites themselves remain opaque.

Any advice on how I can achieve this?
