- -o [profile.icc]
-
Create fast matrix/shaper profile [different filename to outfile.icc]
- -O "description"
-
Fast ICC Profile Description string (Default "outfile")
- -u

- -q [vlmh]
-
Quality - Very Low, Low, Medium (def), High
- -p
-
Use telephoto mode (ie. for a projector) (if available)
- -t [temp]
-
White Daylight locus target, optional target temperaturee in deg. K (deflt.)
- -T [temp]

White Black Body locus target, optional target temperaturee in deg. K
- -w x,y
-
Set the target white point as chromaticity coordinates
- -b bright
-
Set the target white brightness in cd/m^2

-
Set the target response curve advertised gamma (Def. 2.4)
Use "-gl" for L*a*b* curve
Use "-gs" for sRGB curve
Use "-g709" for REC 709 curve (should use -a as well!)
Use "-g240" for SMPTE 240M curve (should use -a as well!)
Use "-G2.4 -f0" for BT.1886

- -e [n]
-
Run n verify passes on final curves
- -z
-
Run only verify pass on installed calibration curves
- -P ho,vo,ss[,vs]
-
Position test window and scale it
ho,vi: 0.0 = left/top, 0.5 = center, 1.0 = right/bottom etc.
