XCMSDB 1 "Release 5" "X Version 11"
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:
8
-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.
8
-remove This option attempts to remove the XDCCC properties on the screen's root
window.
8
-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.
8
-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.
