Comments
LPCMYK_PARAMS is a pointer to a CMYK_PARAMS structure. Where the function parameter type is LPCMYK_PARAMS, you can declare a CMYK_PARAMS variable, update the structure's fields, and pass the variable's address. Declaring a LPCMYK_PARAMS variable is necessary only if your program requires a pointer.
CMYK_PARAMS is used with the CONVERSION_PARAMS structure.
The mask value will be used only when updating the CMYK conversion using L_ClrSetConversionParams function.
The higher the GCR, the more the gray components are replaced with blackness.
