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.
