unu quantize: Quantize values to 8, 16, or 32 bits. Input values can be fixed point (e.g. quantizing ushorts down to uchars) or floating point. Values are clamped to the min and max before they are quantized, so there is no risk of getting 255 where you expect 0 (with unsigned char output, for example). This does not do any non-linear quantization. See also "unu convert", "unu 2op x", and "unu 3op clamp". Usage: unu quantize -b <bits> [-min <value>] [-max <value>] [-i <nin>] \ [-o <nout>] -b <bits> = Number of bits to quantize down to; determines the type of the output nrrd: o "8": unsigned char o "16": unsigned short o "32": unsigned int -min <value> = Value to map to zero. Defaults to lowest value found in input nrrd. (double) -max <value> = Value to map to highest unsigned integral value. Defaults to highest value found in input nrrd. (double) -i <nin> = input nrrd -o <nout> = output nrrd (string); default: "-"
