Barcode Reading Quality

 
  Question
 

Is it possible to receive a the quality or confidence with which a 2 dimensional barcode was decoded by CVB Barcode?

  Answer
 

In principle yes. PDF417 and DataMatrix codes both have built-in error-correction information. In the CVC_BC_Info Structure there is a corresponding entry called used_ecc, that tells you the percentage of this error-correction information that had to be used to properly read the code. The lower this value is, the easier the code was to read.

For 1D-codes there is no corresponding method.
