Thanx. But I am relatively newbie. When I have selected by colour (Shift-O), 
the menu choice for inversion (Ctrl-I) is not active.

I would highly appreciate if you could explain me using teaspoons. NB it is 
MY fault, not yours.

[Gimp-user] Color - transparency

2004-06-02 Thread Egon Brinken
I have a gif-picture, with two layers. The one transparent. 

How can I subtract one specific color from the picture layer, e.g. let the 
uniform colored background be replaced by transparency? (The resulting 
picture must be saved as a gif-file, I presume. It shall be used on my 
web-pages)

Plug-ins-Colors-Color to alpha.
Copy your color of the background to the box and you have what you
wanted.
