Qr-Code-Scanner- | simple QR code scanner with Room Database | QRCode Processing library

I am Working on Android App that Scan the QR using Zxing Library. I Implemented the Zxing QR Scanner using Fragment. the Main Issue I face is the Camera Always open in Landscape but In Original Project which I am following always open in Portrait mode. Here is the Tutorial that I am following Tutorial

I have added the Orientation in Manifest as well as on the Fragment.

Here is My Main Fragment

I am working on Android app which uses Zxing to Scan QR Code on fragment, For achieving that I followed this Tutorial to get the Desired result.Link I Followed to Scan QR on Fragment

The Code I used to Scan QR On **QRCodeFragment ** Fragment looks

I'm using Android studio 4.0, coding in Kotlin and I'm still really new at Android development.I need to integrate the Xzing barcode libray. I've copied some code from the tutorial at [https://tutorialwing.com/implement-android-qr-code-scanner-using-zxing-library-in-kotlin/][1]. The tutorial uses the following import statement:

I've tried testing the c# code for a QR code reader in this answer here

I just copy pasted the code into a C# script and placed it in the ARCamera prefab just like how the KDelli said but I've been getting this error:

error CS0117: 'Image' does not contain a definition for 'PIXEL_FORMAT'

from these two lines:

I created a QR/ Barcode scanner in my ionic project by using this online link https://www.freakyjolly.com/ionic-4-add-barcode-qr-code-scanner-encoder-ionic-4-native-plugin/

the qr code is working fine and generating an XML output data of qr code. below is xml out put iam getting.

Before posted I did search for this answer but didn't find what I need so would like to ask if you kindly can help me.

I have iOS Swift app that scans QR codes which is in my case calendar event then show it as alert popup. What I need is to scan QR Code (calendar event) and when scanned prompt if Event will be added into calendar, also limit scanning to event QR Codes.

Code that worked was from https://medium.com/@gayatri.hedau/qr-code-scanner-with-avcapturesession-ios-swift-5007ee498b49, but there you can just confirm that you have seen scanned info.

QR code with event info is created on https://qrcode.tec-it.com/en/Calendar

I don't know so much but I think that bellow part of code should be adjusted as this part shows alert QR code.

I am using Zbar C++ library to decode QRCode,using this tutorial: https://www.learnopencv.com/barcode-and-qr-code-scanner-using-zbar-and-opencv/

Here I have to decode only QRCode from an image however using this tutorial it decodes both QRcode and barcodes from an Image.

In tutorial it says to decode only QRCode we have to Configure Zbar Imagescanner properly.

In tutorial they are using following configuration to decode both QRCode and Barcodes ImageScanner scanner; scanner.set_config(ZBAR_NONE, ZBAR_CFG_ENABLE, 1);

So to decode only QRCode I am using following configuration: ImageScanner scanner; scanner.set_config(ZBAR_QRCODE, ZBAR_CFG_ENABLE, 1);

But using this Zbar configuration still it decodes both QRCode and barcodes data.I am getting Decoded Data type as EAN-13 and QR-Code.

How I can configure Zbar sccanner properly so it decodes only QR-Code Data type?

I have spent weeks looking for a way to turn my webcam (built into the computer) into a QR scanner using Python but nothing has worked.

In the first instance, I tried installing this software which supposedly would allow me to turn my camera into a barcode scanner, which could then use this video to decode the codes in python. I installed the scanner along with 'pywin32' which was supposedly the library I needed to use, but I couldn't get the two to communicate as my computer kept saying that pywin32 has not been installed (although it had).

Then, I moved onto using zbar/ pyzbar. I downloaded all of the modules that were recommended (I followed the instructions set out on here) but these each came with several more error messages. It was all to do with various libraries and modules not being installed - I've tried downloading PIL/pillow, pyqrcode and a number of other things that are supposed to work, but for some reason, don't.

I don't feel that I can provide any evidence of code as I haven't got any code to fix for this particular issue -- I am simply looking for anyone who may know of a way to transform an ordinary webcam into a barcode/qr scanner using python.

Assuming none of the libraries I need are installed on my computer at the moment, could someone please explain to me exactly which libraries I will need to download, where I can find them, and how I could use them to make Python communicate with my webcam?

This is for my A Level Coursework and the scanner is absolutely fundamental to the program; if anyone can provide me with a useful, understandable solution then I would be really grateful. I apologise if this question is still a little too broad - I am a complete novice to coding and after searching endlessly for hours to find a solution, I feel that this is my final resort.

I've develop a project using zxing to scan the barcode. I had followed the tutorial from here, but unfortunately I got error when I tried to run the project to device. The error that I get is

This is the build.gradle(app)
