ARGUMENTS¶
- display
- Specifies the connection to the X server.
- ccc
- Specifies the CCC.

Client White Point is to be assumed to be the same as the Screen White

- compression_client_data
- Specifies client data for use by the gamut compression
procedure or NULL.
- compression_proc
- Specifies the gamut compression procedure that is to be
applied when a color lies outside the screen's color gamut. If NULL is
specified and a function using this CCC must convert a color specification
to a device-dependent format and encounters a color that lies outside the
screen's color gamut, that function will return XcmsFailure.
- screen_number
- Specifies the appropriate screen number on the host
server.
- visual
- Specifies the visual type.
- white_adjust_client_data
- Specifies client data for use with the white point
adjustment procedure or NULL.
- white_adjust_proc
- Specifies the white adjustment procedure that is to be
applied when the Client White Point differs from the Screen White Point.
NULL indicates that no white point adjustment is desired.
