Enable Color Matching Block

You pass a structure defined by the TEnableColorMatchingBlk data type to the PrGeneral function when you use the EnableColorMatchingOp opcode, described in "PrGeneral Function Operation Codes" (page 3-37). ColorSync-supportive drivers support the EnableColorMatchingOp operation code as a PrGeneral call that turns the fEnableIt flag on or off to enable or disable color matching.

struct TEnableColorMatchingBlk {
   short                iOpCode;
   short                iError;
   long                 lReserved;
   THPrint              hPrint;
   Boolean              fEnableIt;
   SInt8                filler;
};
