How can I read ITF ticket barcode (size 44) encoded in the Interleaved pattern 2 of 5. Using some library like zxing, zbar, etc.?
I have already used the zxing and zbar libraries but do not recognize the ticket barcode.
Now try the examples:
Of all the examples I find I can read all types of bar codes (QR Code, Code 39, 93, 128, ITF, etc.) to small size ITFs. Less the boleto bancário.
Does anyone have any idea what I can do?
It is possible to read Brazilian ticket bar code with the ZBar library. What you have to do is set the video quality to high. Here is the ZBarReaderViewController configuration code snippet.
// ADD: present a barcode reader that scans from the camera feed
ZBarReaderViewController *reader = [[ZBarReaderViewController alloc] init];
reader.readerDelegate = self;
reader.supportedOrientationsMask = ZBarOrientationMaskAll;
reader.videoQuality = UIImagePickerControllerQualityTypeHigh;
ZBarImageScanner *scanner = reader.scanner;
// TODO: (optional) additional reader configuration here
[scanner setSymbology: 0
config: ZBAR_CFG_ENABLE
to: 0];
[scanner setSymbology: ZBAR_I25
config: ZBAR_CFG_ENABLE
to: 1];
Since version 7 of iOS the AVFoundation framework offers a native method for reading bar code. However, support for Interleaved Standard 2 of 5 ( AVMetadataObjectTypeInterleaved2of5Code ) was recently introduced in iOS ( 8 .
I have modified the example in this tutorial and it really works well for reading barcodes from tickets both title and covenant.
