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.
