For PDF417 the form is a (bcdefg) and has the following meaning:
Index Characteristic Description
a Overall quality The minimum or worst quality of all characteristics.
b Start/Stop pattern The quality of the start and stop patterns.
c Codeword yield Amount of Codewords that are decoded correctly.
d Unused error correction Measures and grades the reading safety margin
that error correction provides.
e Modulation The measure of the amplitude between two
symbols specifies how reliable they can be
distinguished.
f Decodability Describes, how far the true width of the moduls
differ from the standard of the code types.
g Defects Indicates, to what extent irregularities or
disturbances occur in individual symbol modules.
Structure of the quality result string of 2D code types borrowing from ISO/IEC TR 29158
The string with the format a (bcdefghij) indicates the determined quality which has the following meaning:
Index Characteristic Description
a Overall quality The minimum or worst quality of all characteristics.
b Cell contrast Describes the difference between the highest and the
lowest reflectance values of the gray value profile.
Calculation of this characteristic differs from
calcualation of "Contrast" of ISO/IEC 15415.
c Cell modulation The measure of the amplitude between two symbols
specifies how reliable they can be distinguished.
Calculation of this characteristic differs from
calcualation of "Modulation" of ISO/IEC 15415.
d Fixed pattern damage Measures and grades any damage to the finder pattern
and quiet zone in the symbol.
e Decode Binary characteristic of the readability. If it can be
decoded, then it will be A otherwise F. In this
implementation it will always be A.
