qr-code

I was wondering if there is a good library for python for decoding QR code. Basically what I would like is to give library image with QR code on it and the library would output contents saved in image. I've looked before with no success. Two problems are that native c code can't be compiled and you can't get access to the file system. pyqrcode didn't work out and neither did zxing. Have you already looked at : http://pyqrcode.sourceforge.net/ If code compiling does not work for you, then there is also pure python implementation at : http://github.com/hcvst/pyqr If you're still looking for

Is there a BlackBerry library/component (open source or commercial) for integration in my own application that acts as QR code reader? I'd like to fully integrate it in my application. Or alternatively: is there a way to use the open source ZXing library in combination with the camera, ideally with live detection of the code? If you're targeting BlackBerry 6, RIM has now included the ZXing library as part of the OS: http://devblog.blackberry.com/2010/10/barcode-api/ For pre-6.0.0 applications, the webpage for the zxing project mentions JavaME and RIM-specific modules: http://code.google.com/p

Has anyone heard of this before ? Extract the QR Codes (all the QR Codes must be in same Width and Height {square}) and get the data from each QR Code , and combine them. Then get the every pixel value from each QR Code and change them to hexadecimal . You will give #FFFFFFFF , #FF000000 , #00000000 (white,black, transparent) and the like (but for black and white QR Code , it would only 2 of them). Then for each value from each QR Code, by creating a new colour QR Code which the colour is according to the value from each hexadecimal and the content of the new colour QR Code will have the

The following code works perfectly and fast if I am scanning a QR code with an URL. However, if I am decoding a QR code with a simple string or number sequence (which is what I would like to do), it randomly works sometimes, but 99% of the time it keeps failing with a ChecksumException. if (webcam.isOpen()) { if ((image = webcam.getImage()) == null) { continue; } LuminanceSource source = new BufferedImageLuminanceSource(image); BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source)); try { result = new QRCodeReader().decode(bitmap); } catch (NotFoundException e) { //exception

I run a simple demo to use cordova-plugin-qrscanner, it can scan qrcode but no camera preview. qrscannerDemo on Github Related code blow: import { Component } from '@angular/core'; import { NavController } from 'ionic-angular'; import { AndroidPermissions } from '@ionic-native/android-permissions'; import { QRScanner, QRScannerStatus } from '@ionic-native/qr-scanner'; @Component({ selector: 'page-home', templateUrl: 'home.html' }) export class HomePage { constructor(public navCtrl: NavController, public androidPermissions: AndroidPermissions, public qrScanner: QRScanner) { } qrscanner() { //

I have downloaded from git latest zBar QR Code Scanner (SDK 0.2). I am trying to implement it in my application. I work on Android Studio. What have I done: I have copied zBar.jar to libs folder of my Project. I have created *.jar files from "amerabi", "amerabi-v7a", "x86" by zip'ing them and changing their format to *.jar. I have copied amerabi.jar, amerabi-v7a.jar and x86.jar to libs folder of my Project. There is no need to change anything in gradle because it is already configured to import every jar file from libs projects. See below: dependencies { compile 'com.android.support:support-v4

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
