.SH DESCRIPTION
|
|
The
|
|
.ZN 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
|
|
.ZN XcmsCIEXYZFormat ,
|
|
.ZN XcmsCIEuvYFormat ,
|
|
.ZN XcmsCIExyYFormat ,
|
|
or
|
|
.ZN XcmsUndefinedFormat .
|
|
If \fIcolor\fP is NULL, this function sets the format component of the
|
|
Client White Point specification to
|
|
.ZN XcmsUndefinedFormat ,
|
|
indicating that the Client White Point is assumed to be the same as the
|
|
Screen White Point.
|
|
.LP
|
|
The
|
|
.ZN 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.
