Color Manager Functions

Managing Colors

pascal long Color2Index(const RGBColor *myColor); 
pascal void Index2Color(long index, 
RGBColor *aColor); 
pascal void InvertColor(RGBColor *myColor); 
pascal Boolean RealColor(const RGBColor *color); 
pascal void GetSubTable(CTabHandle myColors, 
short iTabRes, 
CTabHandle targetTbl); 
pascal void MakeITable (CTabHandle cTabH, 
ITabHandle iTabH, 
short res); 

Managing Color Tables

pascal long GetCTSeed(void); 
pascal void ProtectEntry(short index, 
Boolean protect); 
pascal void ReserveEntry(short index, 
Boolean reserve); 
pascal void SetEntries(short start, 
short count, 
CSpecArray aTable); 
pascal void SaveEntries(CTabHandle srcTable, 
CTabHandle resultTable, 
ReqListRec*selection); 
pascal void RestoreEntries (CTabHandle srcTable, 
CTabHandle dstTable, 
ReqListRec *selection); 

Operations on Search and Complement Functions

pascal void AddSearch(ColorSearchProcPtr searchProc); 
pascal void AddComp(ColorComplementProcPtr compProc); 
pascal void DelSearch(ColorSearchProcPtr searchProc); 
pascal void DelComp(ColorComplementProcPtr compProc); 
pascal void SetClientID(short id); 

Application-Defined Functions

pascal Boolean MySearchProc(RGBColor *rgb,
long *position);
pascal void MyCompProc	(RGBColor *rgb);
