Arguments:

  • _shift_value>0,_negate={ 0=no_negation | 1=negate },_[palette],_seed_a...

Description:

Custom mapping function with more options than default map.

_shift_value defines the shift of base values used for mapping of color. This can be either percentage of integer.
_[palette] is used to map into image.
_seed defines the seed per image. Note: If you had inserted no argument, but a comma before, then it will pick random. If there is no argument and no comma, then it will use default map method. If this is your only argument, then the seed will defines the output. Sequentive arguments will also be used as seed for output for each images.

Default values:

_shift_value=n/a,_[palette],_seed=n/a
