I have a web project where I'm using @zxing/library for a qr scanner/ reader feature. I'm using decodeOnceFromVideoDevice method, that they are exposing, but when i scan a qr code it somehow enter the same method twice instead of just ones. because of this i have duplicate entries in my database. Techologies: React , C# web api for the backend, entity framework and sqllite as db.
..."qrscan" () dart library to do the same in app extremely well, but every node library I've found is having no luck. The problem looks to be that the browser is using a much lower quality camera stream. I'd like to use "react-qr-reader" () as it's well maintained and easy to integrate, but I've also tried the ever popular ZXing library with no better luck. An example component would be: <QrReader className="scanner__camera-frame" onResult={(result, error) => (result)} constraints={{ facingMode: 'environment' }} /> and I've tried using various constraints, such as: constraints={{ facingMode: 'environment', focusMode: "continuous", zoom: 4.0 }} The camera in the browser app ...

...of filter. There may already be such filters built into the library Im not aware of, I think there is luminescence and histogram functions that may be tapped into. *Important! This barcode scanner uses the rear camera of any smartphone. You must have a smartphone to use this web app, and test with it. Here is a similar version of the web app I need enhanced, you need to visit this URL ( ) with your phone, select the rear camera from the dropdown, and then click start to activate the scanner. Then you need to scan the barcode I have attached to this project description, and add the first 12 characters of the data that comes up from scanning this barcode into your bid. This tells me 3 things: -you read the description completely before
I need help to read PDF417 barcodes in Xamarin Forms and decode the data. I tried with a popular library in Nuget (ZXing) but for a strang reason doesn't read this type of barcode but is included in the official documentation The expected file: An example app in Xamarin forms with the reader to implement into my app. I attached the specific type of PDF417 barcode that I need read.
I'm currently using python zxing to read barcodes from images (via pip3 install zxing) under Linux environment. However, the barcode has to be extremely clear and free from skew for zxing to detect the barcode (even in try-harder mode) I need a new solution/library or some kind of image pre-processing to greatly improve the detection rate of barcode. Please check the attachment for barcodes not being detected by zxing. I will only award project if you already found a solution to my problem, I will create milestone and you will share with me the solution.

Needed is code to detect and decode Aztec codes from a smartphone camera image. It must be able to detect codes reliably and fast. Even if they are - big (contain a lot of data) - tilted - rotated (See sample Images) The implementation available in the open source ZXing library does provide code to decode Aztec patterns, but does not meet our requirements as it cannot cope even with the slightest distortion when decoding big codes. The solution should have comparable performance and robustness reading Aztec codes as this "NeoReader QR & Barcode Scanner" app: Nonfunctional requirements The code will be used in a Application. So the solution should ideally be implemented as a C# Xamarin project (Alternatively
Hi! I need a working solution for a Barcode scanner developed for html5 and that can use the rear camera in both Android + iPhone. This solution will be applied in an existing site already in a https hosting.
Project Scope: Add new barcode decoding engine (ML Kit) to existing Android Studio project. History: Our existing application are using the zxing PDF417 barcode decoding API we need to add a secondary barcode decoder API to our project as the ML Kit can decode higher density barcodes (PDF417). Work needed: Add a secondary barcode engine to the project see with example source available on App workflow: (1) User click on button [SCAN] to open and display a new UI (2) User scan barcode (3) Decode barcode through ML Kit API and count the number of characters if it is a certain length long return to main to be encoded and submitted to our backend server.

I need a client side js solution for scanning code128 format barcodes with my i-phone camera. I have used a few SDK's I found on github, and they work, but terribly slow. I need one that can scan Code128 1D barcodes, fast. Must work on my iPhone 7 running IOS 13. I want to be able to live scan the barcode - not upload a picture of a barcode - must be able to live scan. Needs to scan within a couple seconds, not take forever to get lined up and read. If I use this sample on my iphone it works fine, but it is webpacked and I am unable to extract the example into something that actually works for me. I have a form, I want to press a button, have a scan screen come up, scan barcode, and then return value into input field. Fast and accurate.

When the app scans the QR code it sends a Restful to the server with the QRcode and App code (serial number) I have a wire frame design (attached) to shows the UI. I have the app mostly completed but for some reason the QR reader is not scanning. Some other items might need attention also because I cannot test it until the QR works. a) it must use ZBar not Zxing b) This project Android Gradle from Github works very well. If the scanning and zoom part of that can be built as a library jar and then linked into the Xamarin (which I read is possible) that would work well I think. Needed in about 2 days pl...

Hi, I need help integrating a qrcode/2d barcode(zxing) reader into an esp32/arduino sketch.
We require similar functionality as shown at the website: for QR codes. We would like to scan barcodes (mainly PDF417) with the same real-time capability (compared with old method: take photo, crop, upload for barcode data to be "read" required). ZXing has the PDF417 capability, but not real-time capability. For examples of PDF417, take a look at:

This is a simple QR code scanner project that should be developed for Android and iOS with Visual Studio and Xamarin. The screenshots are showing how the app should look and feel as well as all differents steps/screens the user will see while using it. The App will be able to - scan QR codes - there won’t be any user warning if the QR codes are redirected to our webs...as well as for the “flash light” icon. We’ll request to have all source files send to us once the project validated and ready to publish files for Google play and iTunes. NOTE: the look and feel is strongly taken from the already existing free app for Android “privacy-friendly-qr-scanner” (you can google it) and using the zxing library
...Android devices (Samsung Galaxy s7, Samsung Galaxy s7 edge etc). The main reason is that we need to use Front camera to detect QR code. Android devices support only Fixed mode for front camera, not supporting AUTO_FOCUS and camera resolution is also poor than rear camera. So the qr image from camera frame is out of focus and blurred. So we do deblurred and defocused using OpenCV and then use Zxing for QR detection. deblurred and defocused module is working on iPhone, but not working on Android. Samsung's front camera has better quality than iPhone6, but The deblurred and defocused module is working well on iPhone6 but not working on Samsung's android devices. It can be related with camera aperture, as you can see in below list, Samsung's device : f/1.7, iPhone...

I need to build an Android App capable of scanning all bar codes in a product label, including 2D, and 1D high density bar codes. Probably using the Zxing library. The scanned information has to be entered into a relational database and also stored in memory.
I need an Android application which can read barcode (you can use 3rdparty, ZXing is mainly recommended, but other reader can be good also [with commercial use license]), and communicate with local (needs RELATION DB, SQLite recommended) and remote (cloud) databases (through php requests). However I need an view (table) which can show the actually local DB items. Some details: I need one view which has live camera stream and show an barcode reader line (and can read barcode if there is one). This view has some input text area, where the user can write data. And has 2 button (no barcode, and add/remove toggle switch). The add and remove function is different, but very similar. This views layout is in the view_1 attached image. The other view looks like a table, which is filled with ...

I am developing a barcode reader integrated desktop application using C#. I tried ZXing for barcode reading but it fails to detect barcodes for attached images. So I'm searching out help from experienced developers. Actually you don't need any coding for this job. I want you to find A FREE BARCODE SDK which can read the attached images. So if you have experience in barcode readers, you can only test your past works for the attached images. Or if you have an idea to read them successfully using ZXing (maybe using some filters), that will be better for me. Thanks.
