NAME
       xcmsdb - Device Color Characterization utility for X Color Management System

SYNOPSIS
       xcmsdb [ -query ] [ -remove ] [ -format 32|16|8 ] [ -help ] [ -version ] [ filename ]

DESCRIPTION
       xcmsdb  is  used to load, query, or remove Device Color Characterization data stored in properties on the root window
       of the screen as specified in section 7, Device Color Characterization, of the ICCCM.  Device Color  Characterization
       data  (also  called the Device Profile) is an integral part of Xlib's X Color Management System (Xcms), necessary for
       proper conversion of color specification between device-independent and device-dependent forms.	Xcms uses 3x3 matri‐
       ces stored in the XDCCC_LINEAR_RGB_MATRICES property to convert color specifications between CIEXYZ and RGB Intensity
       (XcmsRGBi, also referred to as linear RGB).  Xcms then uses  display  gamma  information	 stored	 in  the  XDCCC_LIN‐
       EAR_RGB_CORRECTION property to convert color specifications between RGBi and RGB device (XcmsRGB, also referred to as
       device RGB).

       Note  that Xcms allows clients to register function sets in addition to its built-in function set for CRT color moni‐
       tors.  Additional function sets may store their device profile information in other properties in function  set	spe‐
       cific format.  This utility is unaware of these non-standard properties.

       The  ASCII  readable  contents of filename (or the standard input if no input file is given) are appropriately trans‐
       formed for storage in properties, provided the -query or -remove options are not specified.

OPTIONS
       xcmsdb program accepts the following options:

       -query  This option attempts to read the XDCCC properties off the screen's root window.	If successful, it transforms
	       the data into a more readable format, then sends the data to standard out.

       -remove This option attempts to remove the XDCCC properties on the screen's root window.

       -format 32|16|8
	       Specifies the property format (32, 16, or 8 bits per entry)  for	 the  XDCCC_LINEAR_RGB_CORRECTION  property.
	       Precision  of encoded floating point values increases with the increase in bits per entry.  The default is 32
	       bits per entry.

       -help   This option prints a summary of the available options and exits.

       -version
	       This option prints the program version and exits.
