NAME
pfsclamp - Clamp color and luminance channel values to be within the specified range
SYNOPSIS
pfsclamp [--min <minimum>] [--max <maximum>] [--percentile] [--zero] [--rgb]
DESCRIPTION
Use this command to clamp values of luminance and color channels to be within the specified range. I.e. if a value in the channel is above the specified maximum or below specified minimum, set the value to either minimum or maximum. The command operates directly on XYZ channels.
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.
EXAMPLES
pfsin memorial.hdr | pfsclamp | pfsout memorial_cl.hdr Remove possible out-of-range values, for examples zeros, from memorial image. pfsin memorial.hdr | pfsclamp --max 0.95 -p | pfsout memorial_cl.hdr Remove 5% of the brightest pixels from the original image.
