xcalib

xcalib project is a tiny monitor calibration loader for XFree86 (or X.org) and MS-Windows.

Usage:

xcalib [-options] ICCPROFILE
or
xcalib [-options] -alter

where the available options are:
-display or -d
-screen or -s
-clear or -c
-noaction or -n
-verbose or -v
-printramps or -p
-loss or -l
-invert or -i
-gammacor or -gc
-brightness or -b
-contrast or -co
-red
-green
-blue
-alter or -a
-help or -h
-version

Last parameter MUST be an ICC profile containing a vcgt or mLUT tag or empty if the "-a" or "-alter" paramter is used or the LUT is to be cleared.

Use profiles gamma_1_0.icc and gamma_2_2.icc for testing. Profiles with vcg-tables can be created with most profile creation suites. An example profile with a vcg-table is inclued, named bluish.icc, which simulates a very high whitepoint (without further intentions).

Requirements:

· ICCLIB (optional)
· Little CMS (optional)
