5.2.7 Quality Information
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. The reader outputs the quality information individually if there are
multiple symbols. Quality Information is not added at Reading Error.
Output format: (QT: ddd)
ddd: Quality (000 to 100)
5.2.8 Symbol Coordinates
The positional data of the symbol in the image is output along with the decoded
data.There are two types of output information; barycentric coordinates and
rectangular coordinates.
(1) Barycentric coordinates
The origin (+0000, +0000) is the left-top edge of a field of view.
(Example output)
10000000099070(+0122,+0024)
Output format: Header + Data + (abbbb,acccc) + Terminator
a : + or -
bbbb: X coordinate of a symbol's barycenter (9999 to +9999)
cccc: Y coordinate of a symbol's barycenter (-9999 to +9999)
(2) Rectangular coordinates
The origin (+0000, +0000) is the left-top edge of a field of view.
(Example output)
10000000099070(+0269,+0011)(+0455,+0086)(+0386,+0270)(+0198,+019
