   int  imageNo,
   int  mode
);

Description

Set the area value.

Example

    int Sample::MeasureProc(ProcUnit *ptrProcUnit)
    {

        double posX, posY, areaA;
        int    outputMode = 0;
        M_AREA   area;

        func_measure(&posX, &posY, &area);

        if (ptrSetupData->outputCoordinate == 1) {
                outputMode |= 0x00000001;
        }
        if (ptrSetupData->calibration == 1) {
                outputMode |= 0x00000002;
        }

        // set data

        area.Set(areaA, ptrProcUnit, 0, outputMode);

    }
