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.
