Relating the iPhone SDK 1.2.
My problem is the same as in discussion topic
where spadix supposed to "open a support request and provide a sample image that demonstrates your problem". I didn't find any related support request.
The same issue - I think - is asked here:
And if I understand spadix right here:
then this can be done somehow(?).
Using ZBar for some time now, up to recently we scanned 1-dimensional bar-codes and "normal" QR-codes containing some numeric or alphanumeric strings (mostly URLs).
A new requirement are QR-codes containing VCARDs - in three forms:
- as simple plain texts: no problem here, already implemented;
and these latter two mean that the QR doesn't contain readable alphanumerics, but binary data!
As an explicitely defined option by the QR Code Standardization:
where there are mentioned 4 types, numeric, alphanumeric, 8-bit bytes (binary), Kanji.
These binaries - of course - can also contain Nulls (which causes the resulting NSString (or the underlying char*) to not even contain all information.
Yes, the problem for me is, that ZBarSzmbol.data is of type NSString (delivering characters, not bytes) and I can't find anything of type NSData (containing the raw bytes).
Two examples of such QR codes are attached (can't get better ones at the moment, sorry, but these should be recognized by ZBar - if not, I could ask for better ones, later).
Hoping, that I explained it understandable.
And of course - sorry - it is urgent :-(
