EAN-13 bar code with an additional 2 or 5 characters

[Dr Egor]

Hi!
Please tell me how to add the ability to read the EAN-13 as 13+2 or 13+5?

ZXing supports decoding the EAN extensions.
When such an extension is found it is returned as a
ResultMetadataType.UPC_EAN_EXTENSION.
However because the extension is optional ZXing will return the base
EAN even if it fails to see the extension (which happens quite often).
If you wish to force ZXing to require an EAN extension you can supply
the DecodeHintType.ALLOWED_EAN_EXTENSIONS with an integer array
containing 2, 5 or both depending on your case.


You can even do this with Web Site Integration (although you'll need
to parse the meta data manually):

Request:
http://zxing.appspot.com/scan?SCAN_FORMATS=UPC_A,EAN_13&ALLOWED_EAN_EXTENSIONS=2&ret=http://my-site.com/{CODE}/{META}
(remember to perform an URL escape for the "ret" parameter)

Result:
http://my-site.com/4820020830281/%7BISSUE_NUMBER%3D3%2C+POSSIBLE_COUNTRY%3DUA%2C+UPC_EAN_EXTENSION%3D03%7D
The META part is URL Encoded: {ISSUE_NUMBER=3, POSSIBLE_COUNTRY=UA,
UPC_EAN_EXTENSION=03}
