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

SYNOPSIS
     /usr/bin/xcmsdb [ -query ] [ -remove ] [ -format 32|16|8 ] [
     filename ]

DESCRIPTION
     xcmsdb is used to load, query, or remove Device Color  Char-
     acterization data stored in properties on the root window of
     the screen as specified in section 7, Device  Color  Charac-
     terization,  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
     matrices stored in the XDCCC_LINEAR_RGB_MATRICES property to
     convert  color  specifications between CIEXYZ and RGB Inten-
     sity (XcmsRGBi, also referred to as linear RGB).  Xcms  then
     uses    display    gamma    information    stored   in   the
     XDCCC_LINEAR_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  pro-
     file   information  in  other  properties  in  function  set
     specific 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
     transformed 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

             32 bits per entry.
