SYNTAX
XcmsCCC XcmsCreateCCC(Display *display, int screen_number, Visual *visual, XcmsColor *client_white_point,
XcmsCompressionProc compression_proc, XPointer compression_client_data, XcmsWhiteAdjustProc
white_adjust_proc, XPointer white_adjust_client_data);
void XcmsFreeCCC(XcmsCCC ccc);
ARGUMENTS
display Specifies the connection to the X server.
ccc Specifies the CCC.
client_white_point
Specifies the Client White Point. If NULL is specified, the Client White Point is to be
assumed to be the same as the Screen White Point. Note that the pixel member is ignored.
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.
DESCRIPTION
The XcmsCreateCCC function creates a CCC for the specified display, screen, and visual.
The XcmsFreeCCC function frees the memory used for the specified CCC. Note that default CCCs and those
currently associated with colormaps are ignored.
