xcmsdb --
Xlib screen color characterization data utility
Syntax
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 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
The 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.
Environment variables
DISPLAY-
