Hello,
I am searching for a "easy" way to get the following :
I do some painting on an image. After this I got many areas whit black or nearly black color values.
What I want to get now is to set those "blacked" pixels to translucent.
Maybe something like
if red/green/blue-value of pixel is less 25 then set alpha to 0
Is there anything like this known?
Regards,
Spinnifex

I don't know of one off hand, but that would be very easy to implement as a subclass of AbstractFilter.
