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.
