Scaling factor
A power-of-two gain on the result of arithmetic operations
Definition
The Scaling factor is an exponent, not a multiplier. An arithmetic operation computes its value v at each pixel, and the result is multiplied by 2s, where s is the Scaling factor. The default, 0, changes nothing, and each step of 1 doubles or halves the result. Its job is to land the value inside the output's bit depthLoading....
A gain on the output
Powers of two, default 0
Which way the sign scales
The reference is inconsistent about the sign
Aim to fill the range
Read the histogram, then step
Arithmetic only
Not on filters or Complement image
