ZXing: Finding the bounding rectangle of Barcode

余生颓废 提交于 2019-12-06 02:34:55
问题 I was experimenting with ResultPoints which returns the points related to the barcode in the image. For a QR Code, ResultPoints returns a set of 4 points which are the coordinates of the four boxes at each corner of the QR Code. When I experimented the same with a Barcode, it returns two points which denote the width of the barcode. How do I find the bounding rectangle of the barcode? Is there any way by which I can calculate the coordinates of the top left corner and bottom right corner of

Does CIDetector For other Barcode Types

主宰稳场 提交于 2019-12-05 18:42:23
I am looking at CIDetectorTypeQRCode. How can I detect other types of barcodes? I can read other barcode types via AVMetadataObjectType, however I want to do the same with CIDetector. I am trying to achieve real time highlighting of the barcode. Trying for a sort of zoom in effect before my AVCaptureMetadataOutputObjectsDelegate achieves a full lock and read of the code. CIDetector has only following types to detect, So we can't use it to detect another type of barcodes. CIDetectorTypeFace CIDetectorTypeRectange CIDetectorTypeQRCode CIDetectorTypeText But since iOS 11 has introduced a new set

I'm trying to create a simple EAN13 image to show a barcode from a String. I tried with this code but it can only generate a code128. What can I use to generate a EAN13? class Barcode { class func fromString(string : String) -> UIImage? { let data = string.dataUsingEncoding(NSASCIIStringEncoding) let filter = CIFilter(name: "CICode128BarcodeGenerator") filter.setValue(data, forKey: "inputMessage") return UIImage(CIImage: filter.outputImage) } } let img = Barcode.fromString("1234567890123") you can try this EAN13BarcodeGenerator Usage is pretty simple: BarCodeView *barCodeView = [[BarCodeView

How do I omit the leading 0 from a 128C bar code?

旧时模样 提交于 2019-12-05 12:36:50
If I put 12345, for example, in a "text" bar code's property, the output is 012345. This "0" is the problem. How I can remove this? I'm using Delphi 2010 and FastReport 4.9.72. A Code 128C barcode needs to be an even number of digits. This is by design. There is a 1:1 mapping between the numbers and the resulting output, and the output is 2-digit aligned. In the case of 1 the Code 128C representation of this number is 01 if the value was 12 then the underlying representation would be 12 so the digits 628 can only be represented by 0628 The wikipedia article about Code 128 explains the

Is libdmtx dead, suggested replacement?

这一生的挚爱 提交于 2019-12-05 12:04:57
I've been using libdmtx in a project and looking to update to a newer version, but it seems the project hasn't been updated in well over a year. The last update/version was June, 2011. The Git repository shows that the last commit was August, 2011. Finally, the author's web site, which previously promoted libdmtx, Dragonfly Logic , is dead with a 404 Not Found error. Is there another data matrix library that can meet this criteria? Open source Platform-neutral C/C++ (i.e. can build for Windows, POSIX environments) Encodes/decodes data matrix Actively maintained Alternatively, did libdmtx move

GS1 barcode parsing

妖精的绣舞 提交于 2019-12-05 09:29:01
We need to parse the GS1 datamatrix barcode which will be provided by other party. We know they are going to use GTIN(01), lot number(10), Expiration date(17), serial number (21). The problems is that barcode reader output a string, the format is like this 01076123456789001710050310AC3453G321455777. Since there is not separator and both serial number and lot number are variable length according to GS1 standard, we have trouble to identify segments. My understanding is that it seems like the best way to parse is to embed the parser in the scanning device, not from the application. But we didn't
