Finally figured out the K adjustment and applied. Remaining is making it bitexact to add a FATE test, and add >8bit support. [...] For the record, the original formula I was using was: f(v,a) = clip(-a, -v, 1-v) . R and taking k into account, it is now: f(v,a,k) = clip((-1-a).k - a, -v, 1-v) . R With: f adjustment function a user component adjust (normed to [-1;1]) v component value (normed to [-1;1]) k user K adjust R adjust range -- Clément B.
