This means that with exception * of the provided DD color spaces: * RGB and RGBi * DD color spaces may have different XcmsColorFormat IDs between * clients. So, you must be careful when using XcmsColorFormat * across clients! Use the routines XcmsFormatOfPrefix() * and XcmsPrefixOfFormat() appropriately. * * RETURNS * XcmsSuccess if succeeded, otherwise XcmsFailure * * CAVEATS * Additional Screen Color Characterization Function Sets * should be added prior to any use of the routine * XcmsCreateCCC(). If not, XcmsCCC structures created * prior to the call of this routines will not have had * a chance to initialize using the added Screen Color * Characterization Function Set. */ { XcmsFunctionSet **papSCCFuncSets = _XcmsSCCFuncSets; XcmsColorSpace **papNewCSs; XcmsColorSpace *pNewCS, **paptmpCS; XcmsColorFormat lastID = 0; if (papSCCFuncSets != NULL) { if ((papNewCSs = pNewFS->DDColorSpaces) == NULL) { /* * Error, new Screen Color Characterization Function Set * missing color spaces */ return(XcmsFailure); } while ((pNewCS = *papNewCSs++) != NULL) { if ((pNewCS->id = _XcmsRegFormatOfPrefix(pNewCS->prefix)) != 0) { if (XCMS_DI_ID(pNewCS->id)) { /* This is a Device-Independent Color Space */ return(XcmsFailure); } /* * REGISTERED DD Color Space * therefore use the registered ID. */ } else { /* * UNREGISTERED DD Color Space * then see if the color space is already in * _XcmsDDColorSpaces. * a.
