Range Parameters
Value - Input value.
Interpolation - Mode used for translation.
Input min - Minimum value of the input range.
Input max - Maximum value of the input range.
Output min - Minimum value of the output range.
Output max - Maximum value of the output range.
Levels - Number of distinct output levels. Only active when using the Steps or Posterize interpolation methods.
Clamp - Clamp the input to the input range. Interpolation modes other than Linear are always clamped.
