OPTIONS --min <val> Lower bound for clamping. Default value: 0.0001 (10^-4) --max <val> Upper bound for clamping. Default value: 100000000 (10^8) --percentile, -p Treat given min and max values as a percentile. --zero, -z Set values out of clamping range to zero, instead of setting to specified maximum and minimum. --rgb Perform clamping in RGB space.
