Member	Description
asymmetry	Parameter used for generating the asymmetry curve. A smaller value indicates more obvious luminance stretching in the dark region. Value range: [1, 30]
second_pole	Parameter used for generating the asymmetry curve. A smaller value indicates stronger luminance suppression in the bright region and better retention of highlighted details. Value range: [150, 210]
stretch	Parameter used for generating the asymmetry curve. A smaller value indicates brighter overall luminance. Value range: [30, 60]
compress	Parameter used for generating the asymmetry curve. A smaller value indicates brighter overall luminance. Value range: [100, 200]
