rep_reverse_engineer_color_curves

Arguments:

  • _array_size>0

Description:

Automatically reverse engineer color curves. All images after [0] will be converted into color curve map while [0] is the reference image.

(equivalent to shortcut command rep_recc).


_array_size is used to define the depth of gradient map, if you're using float, then you need to scale image to something higher than 256. If array size is not inserted, then this filter will automatically find the array size.

Default values:

_array_size=n/a
