XcmsColorSpace()														  XcmsColorSpace()

Name
  XcmsColorSpace - Xcms color space structure.

Availability
  Release 5 and later.

Description
  The  XcmsColorSpace  structure contain the information necessary to convert the encoding of color specifications to other color spaces, and
  to parse a color string encoded specifically for this color space.

  The prefix member points to a string that identifies that a color strings encoding is for this particular color space.

	 <color_space>:<color_space_specific_encoding>

  For example, the prefix "cieuvy:" for the color string "CIEuvY:0.119/0.545/0.254".  Although the prefix in the color string may be  entered
  in uppercase or lowercase, all characters of the prefix specified in the XcmsColorSpace must be in lowercase.

  The  id  member  is  predefined  if  the  color  space is registered with the X Consortium; otherwise assigned at run-time (see XcmsAddCol-
  orSpace()).

  The parseString member points to the color space specific string parsing function.

  The to_CIEXYZ member is pointer to an array of functions that, when executed in sequence, will convert a XcmsColor  structure  encoded  for
  this color space to the CIEXYZ encoding.

  The  from_CIEXYZ member is pointer to an array of functions that, when executed in sequence, will convert a XcmsColor structure encoded for
  CIEXYZ to this color space's encoding.

  The inverse_flag member if set (i.e., 1) indicates that for each function in the to_CIEXYZ list,  there  is  an  inverse  function  in  the
  from_CIEXYZ  list.  Note however that the corresponding order is reversed - the inverse of the first function in to_CIEXYZ will be the last
  function in  from_CIEXYZ.

Structures
  The XcmsColorSpace structure contains:

     typedef XcmsConversionProc *XcmsFuncListPtr;

     typedef struct _XcmsColorSpace {
	 char *prefix;
	 XcmsColorFormat id;
	 XcmsParseStringProc parseString;
	 XcmsFuncListPtr to_CIEXYZ;
	 XcmsFuncListPtr from_CIEXYZ;
	 int inverse_flag;
     } XcmsColorSpace;
