NAME

       xcmsdb - Device Color Characterization utility for X Color Management System

SYNOPSIS

       xcmsdb [-query] [-remove] [-format 32 | 16 | 8] [filename]

OPTIONS

       xcmsdb  program	accepts the following options: This option attempts to read the XDCCC properties off the screen's root window. If success-
       ful, it transforms the data into a more readable format, then sends the data to standard out.  This option attempts  to	remove	the  XDCCC
       properties  on  the  screen's root window.  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.

DESCRIPTION

       xcmsdb is used to load, query, or remove Device Color Characterization data stored in properties on the root window of the screen as speci-
       fied  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 function sets in addition to its built-in function set for CRT color monitors.  Additional func-
       tion 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  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.

ENVIRONMENT

       to figure out which display and screen to use.

XcmsLookupColor()														 XcmsLookupColor()

Name
  XcmsLookupColor - obtain color values from a string.

Synopsis
  Status XcmsLookupColor(display, colormap, color_string,
  color_exact_return, color_screen_return, result_format)
	Display *display;
	Colormap colormap;
	char *color_string;
	XcmsColor *color_exact_return;
	XcmsColor *color_screen_return;
	XcmsColorFormat result_format;

Arguments
  display   Specifies the connection to the X server.

  colormap  Specifies the colormap.

  color_string
	    Specifies the color string.

  color_exact_return
	    Returns  the color specification parsed from the color string or parsed from the corresponding string found in a color name data-
	    base.

  color_screen_return
	    Returns the color that can be reproduced on the Screen.

  result_format
	    Specifies the desired color format for the returned color specifications.

Returns
  Zero on failure, non-zero on success.

Availability
  Release 5 and later.

Description
  The XcmsLookupColor() function looks up the string name of a color with respect to the screen associated with the specified  colormap,  but
  does	not  store the color into any color cell in the color map.  It returns both the exact color values and the closest values provided by
  the screen with respect to the visual type of the specified colormap.  The values are returned in the format specified by result_format.

  The color string may contain a color name that appears in the client-side or X server's color database; or a numerical color	specification
  for any color management supported color spaces such that the string conforms to the uniform syntax:

	 <color_space>:<color_space_specific_encoding>

  For example:

     RGB:red/green/blue
     RGBi:R/G/B
     CIEXYZ:X/Y/Z
     CIEuvY:u/v/Y
     CIExyY:x/y/Y
     CIELab:L/a/b
     CIELuv:L/u/v
     TekHVC:H/V/C

  For  the  RGB  color space, the red, green, and blue parameters are hexadecimal strings of one to four digits.  For each of the other color
  spaces, each parameter is a floating-point number in standard string format.	In each case, each number specifies a value for  one  of  the
  parameters  of  the  color  space.   Old-style RGB color strings beginning with a "#" remain supported for backwards compatibility.  If the
  color name is not in the Host Portable Character Encoding the result is implementation-dependent.  Color names are case-insensitive.

  If format is XcmsUndefinedFormat and the color string contains a numerical color specification, the specification is returned in the format
  used in that numerical color specification.  If format is XcmsUndefinedFormat and the color string contains a color name, the specification
  is returned in the format used in the color name database entry for that color name.

  XcmsLookupColor() returns XcmsSuccess or XcmsSuccessWithCompression if the name is resolved, otherwise it returns XcmsFailure.  If XcmsSuc-
  cessWithCompression is returned, then the color specification in color_screen_return is the result of gamut compression.

Structures
  The XcmsColor and XcmsColorFormat structures are shown on the XcmsColor reference page.
