#71 Aztec: Binary Data

[John Mortlock]

Hi

I am trying to encode binary data into an aztec barcode however I cannot get it to work.

The command I am using to generate the barcode is as follows
zint --binary --barcode=92 -i test.bin

I noticed that the eci mode defaults to 3, however i belive in the case of raw binary this should be 0?
zint --binary --eci=0 --barcode=92 -i test.bin

The hex that gets generated (according to http://www.onlinebarcodereader.com/)

a) c2 90 0a
b) 43 56 57 4b 4f 0a

Thanks for any help,
John

I have also attached the full data I am trying to encrypt, running this through onlinebarcodereader.com gives very different results

Further to this I have found that certain ascii characters are causing problems as well, if I try to encode a simple JSON object.

{"string": "test"}

zint --barcode=92 -i test.ascii

Reading it back

{"string172SR 8=Õ

Hi John,

Your sample data showed up not one but three bugs in my code which I hope I have now fixed. Please have a look at the latest code and let me know if this solves the problems.

openbarcodereader.com does not work with raw binary data, it tries to convert to Unicode. I suggest testing with bctester or something similar:

Sample encodes of your data are attached. Thank you for taking the time to document this problem.

Robin.

Robin,

Thanks for your prompt work in resolving these issues! I can confirm that it is correctly generating barcodes for me.

What are the chances of getting these Aztec fixes bundled into a new 2.6.2 release?

Thanks again,
John

Thanks John,

I agree that this fix is worth pushing out a new version, so the chance is 100%, but it may be a couple of weeks before this happens.

Robin.

[John Mortlock]

Awesome, a couple of weeks works well for me anyway

Thanks Again

John
