_x_c_m_s_d_b is used to load, query, or remove Device Color
Characterization data stored in properties on the root
window of the screen as specified in section 7, Device Color
Characterization, 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 Intensity (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 _f_u_n_c_t_i_o_n _s_e_t_s in
addition to its built-in function set for CRT color
monitors. Additional function sets may store their device
profile information in other properties in function set
specific format. This utility is unaware of these non-
standard properties.
The ASCII readable contents of _f_i_l_e_n_a_m_e (or the standard
input if no input file is given) are appropriately
transformed for storage in properties, provided the ----qqqquuuueeeerrrryyyy
or ----rrrreeeemmmmoooovvvveeee options are not specified.
OOOOPPPPTTTTIIIIOOOONNNNSSSS
_x_c_m_s_d_b program accepts the following options:
----qqqquuuueeeerrrryyyy 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.
----rrrreeeemmmmoooovvvveeee This option attempts to remove the XDCCC properties
on the screen's root window.
----ffffoooorrrrmmmmaaaatttt 33332222|11116666|8888
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.
