barcode

I would like to embed an Aztec Code reader into my app. I need control over the GUI to place some buttons around the camera view, while reading the code to be able to switch the camera on / off (to save the battery) What I found was ZXing - which is not reliable yet. Apps with an own SDK like neoreader , which do not give me the control over my GUI. Is there a solution for that problem? Maybe som libs? Proprietary libs? I found a proprietary lib from manateeworks.com They do offer a lib, which can be used to decode Aztec Codes In case anyone is looking for a more up-to-date answer to this

I'm currently working with AVCaptureSession and AVCaptureMetadataOutput . It works perfectly, but I just want to know how to indicate to scan and analyze metadata objects only on a specific region of the AVCaptureVideoPreviewLayer ? Here is a sample of code from a project I have that may help you on the right track // where 'self.session' is previously setup AVCaptureSession // setup metadata capture AVCaptureMetadataOutput *metadataOutput = [[AVCaptureMetadataOutput alloc] init]; [self.session addOutput:metadataOutput]; [metadataOutput setMetadataObjectsDelegate:self queue:dispatch_get_main

I am look at building a 13 digit EAN bar code scanner which works on the web on mobile devices and will use the devices camera to take an image of bar code to scan and decode. I'm not trying to do this through a native app as I would prefer to make this part of my native website search experience. E.g. website visitors on a mobile will be prompted to scan a bar code without having to open an app. This script works well on desktop https://github.com/EddieLa/JOB and uses the Navigator.getUserMedia property to do all this in JavaScript however support in Android is only just starting and support

I'm using zxing to generate barcodes with different types (EAN, 2of5 and DataMatrix). Generating in general works fine. The only problem I currently have is that zxing only generates a 14x14 pixel bitmap which is way too small. But only when using DataMatrix! EAN13, 2of5/ITF and QR-Codes work perfect with the same code. My code: BitMatrix bitMatrix = new DataMatrixWriter().encode(message, BarcodeFormat.DATA_MATRIX, 1080, 1080, null); int height = bitMatrix.getHeight(); //height is always 14, it doesn't matter what value I pass to the encoder As you can imagine this looks pretty shitty on a

Was anybody able to read the PDF417 barcode with use of the ZXing library on the Android OS? They are supporting this - and according to their page it is in 'alpha' stage. We are not looking for perfect solution - since the PDF417 is pretty complex and needs a very good camera with auto-focus, we can accept that it will be working only on few pre-selected high end devices. We have tried also the Barcode Scanner + available on the Android Market - it has the PDF417 option in the settings, but whatever we read it always fails. We were looking also for commercial SDK, also here on stackoverflow,

I have to generate codes with custom fields: id of field+name of field+values of the field. How long is the data I can encode inside the QRcode? I need to know how many fields\values I can insert. Should I use XML or JSON or CSV? What is most generic and efficient? XML / JSON will not qualify for a QR code's alphanumeric mode since it will include lower-case letters. You'll have to use byte mode. The max is 2,953 characters. But, the practical limit is far less -- perhaps a few hundred characters. It is far better to encode a hyperlink to data if you can. As Terence says, no reader will do
