The Offset/Power/Slope Formula¶
out = (i × s + o)p
where:
out: The color graded pixel code value.
i: The input pixel code value (0 to 1) (black to white).
s: Slope (any number 0 or greater, nominal value is 1.0).
o: Offset (any number, the nominal value is 0).
p: Power (any number greater than 0, nominal value is 1.0).
