XCMSDB(1)                                               XCMSDB(1)


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  conver-
       sion 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 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  proper-
               ties 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.
