Parameters

Name	Type	Description
fDecode	REAL	Decode grade
fSymbolContrast	REAL	Symbol contrast grade
fMinReflectance	REAL	Minimum reflectance grade
fMinEdgeContrast	REAL	Minimum edge contrast grade
fModulation	REAL	Modulation grade
fDefects	REAL	Defects grade
fDecodability	REAL	Decodability grade
fOverall	REAL	Overall code grade, i.e. the minimum achieved individual grade averaged over all scan lines. If different scan lines lead to different decoded data, the overall grade is 0.
