NAME
xcmsdb - Xlib Screen Color Characterization Data utility
SYNOPSIS
xcmsdb [-option ...] [filename]
DESCRIPTION
xcmsdb is used to load, query, or remove Screen Color
Characterization Data stored in properties on the root
window of the screen. Screen Color Characterization Data is
an integral part of Xlib, necessary for proper conversion
between device-independent and device-dependent color
specifications. Xlib uses the XDCCC_LINEAR_RGB_MATRICES and
XDCCC_LINEAR_RGB_CORRECTION properties to store color
characterization data for color monitors. It uses
XDCCC_GRAY_SCREENWWHITEPOINT and XDCCC_GRAY_CORRECTION
properties for gray scale monitors. Because Xlib allows the
addition of Screen Color Characterization Function Sets,
added function sets may place their Screen Color
Characterization Data on other properties. This utility is
unaware of these other properties, therefore, you will need
to use a similar utility provided with the function set, or
use the xprop utility.
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.
-color This option sets the query and remove options to
only check for the XDCCC_LINEAR_RGB_MATRICES and
XDCCC_LINEAR_RGB_CORRECTION properties. If the
-color option is not set then the query and remove
options check for all the properties.
-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.
