bbb : Minimum value of reflectance (000 to 255)
ccc : Contrast [%] =100 x (aaa - bbb) / 255 (000 to 100)
5.2.7 Quality Information (Unused Error Correction)
The percentage of the Unused Error Correction codeword of the 2D code is
added to the decoded data.
For example, if the decoder does not use any error correction, this value would
be 100. If the symbol is not decodable, the Quality Information will not be added.
Output format: (QT: ddd) 8 bytes
ddd: Quality (000 to 100)
