I would recommend merging the white layers together and then  
performing an Alpha To Selection on the resulting layer (hide or  
delete the merged layer afterwards). Then add a layermask to your  
background layer, initialized to the Selection with the "Invert Mask"  
option checked.

[Gimp-user] using Alpha Layers to change white to transparent

2009-03-04 Thread Brenton
This picture shows what I have now:

I made the mistake of creating the image to fade to white. Now I want to use
alpha transparency to have it fade to transparent, for use on non-white
backgrounds. I know there must be a way to change those faded white layers
into fading transparencies.

I have played with the alpha layer thing a lot, but I don't know what
settings to use, and it seems not to do anything anyway. 

Thanks in advance.
