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_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 pro-
file 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.
