NAME

       XcmsSetWhitePoint, XcmsSetWhiteAdjustProc - modifying CCC attributes

SYNTAX

       Status XcmsSetWhitePoint(XcmsCCC ccc, XcmsColor *color);

       XcmsWhiteAdjustProc  XcmsSetWhiteAdjustProc(XcmsCCC  ccc, XcmsWhiteAdjustProc white_adjust_proc, XPointer
              client_data);

ARGUMENTS

       ccc       Specifies the CCC.

       client_data
                 Specifies client data for the white point adjustment procedure or NULL.

       color     Specifies the new Client White Point.

       white_adjust_proc
                 Specifies the white point adjustment procedure.

DESCRIPTION

       The XcmsSetWhitePoint function changes the Client White Point in the specified CCC.  Note that the  pixel
       member is ignored and that the color specification is left unchanged upon return.  The format for the new
       white point must be XcmsCIEXYZFormat, XcmsCIEuvYFormat, XcmsCIExyYFormat, or XcmsUndefinedFormat.  If the
       color  argument  is NULL, this function sets the format component of the Client White Point specification
       to XcmsUndefinedFormat, indicating that the Client White Point is assumed to be the same  as  the  Screen
       White Point.

       This  function  returns  nonzero  status  if  the  format for the new white point is valid; otherwise, it
       returns zero.

       The XcmsSetWhiteAdjustProc function first sets the white point adjustment procedure and  client  data  in
       the specified CCC with the newly specified procedure and client data and then returns the old procedure.
