XcmsSetWhitePoint, XcmsSetWhiteAdjustProc - modifying CCC attributes
SYNTAX
Status XcmsSetWhitePoint(XcmsCCC ccc, XcmsColor *color);
- XcmsWhiteAdjustProc XcmsSetWhiteAdjustProc(XcmsCCC ccc, XcmsWhiteAd
- justProc 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.
