nFactor

Value that indicates the factor to be applied in the method operation specified in the lFlag parameter. This parameter is used only if lFlags is FILLLUT_EXPONENTIAL, FILLLUT_LOGARITHMIC or FILLLUT_SIGMOID. If FILLLUT_EXPONENTIAL or FILLLUT_SIGMOID flag is selected its value can be any integer (+/-). If FILLLUT_LOGARITHMIC flag is selected its value should be >= 0. If nFactor = 0, the lookup table will be filled linearly.
