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.
