qr-code

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I have to development an QR Generator in Cocoa. but currently I was used QR Library for iPhone and ported to Cocoa by me. but just found many bugs since iPhone version in Generator Algorithm. then, Is there any QR Encoding Library in Cocoa ? I've mostly only seen Objective-C libraries that read various code types. Don't forget, though, that Objective-C is a superset of C ... http://fukuchi.org/works/qrencode

I am trying to build an application in python that would encode and decode QR codes. I am successful with the encoder, but i don't find libraries(but zbar ) for decoding in python. I am using Python 2.7 in a Windows 7 system. I am not able to install zbar in my system. I installed the dependency module required by the library and even then I end up with so many errors, whenever I try to install it - so many syntax errors in zbar.h and in zbarmodule.c. I don't understand why and clueless about what the problem is. I get the following errors while installing zbar C:\Users\vijay>easy_install zbar

I am able to scan qr code with camera without using any external libraries like ZBAR or ZXING. Now what I actually want is to let the user upload an image from photo library and get the qr code scanned from that uploaded image. I know how to use UIImagePickerController (used it before). What I want to ask is that, How can I scan qr code from an uploaded image (without using the camera) You can suggest some code (.h / .m files) that I can add in my project. Please don't suggest me any external libraries like ZBAR or ZXING. I know you might have found solution for this but i am replying to the

I use qr-image plugin for Nodejs to generate a QR code and it works pretty good. The problem is showing result image in ejs. var express = require('express'); var router = express.Router(); var qr = require('qr-image'); router.get('/', function(req, res) { var code = qr.image("text to show in qr", { type: 'png', ec_level: 'H', size: 10, margin: 0 }); res.type('png'); code.pipe(res); // res.render('index', { title: 'QR Page', qr: code }); }); When i uncomment last line, nodejs crashs. How to send code to view as a variable? Update: This code returns [object Object] in result page. var code = qr

I hope you can help me with this. Im using the Zxing Embedded Library in order to use the QR scanner, the problem is that is on Landscape mode and I would like to change it to Portrait. I have this on the dependencies of my Graddle compile 'com.journeyapps:zxing-android-embedded:2.0.1@aar' compile 'com.journeyapps:zxing-android-integration:2.0.1@aar' compile 'com.google.zxing:core:3.0.1' and I have this in my java class to activate the scanner with a button... public void scanQR(View view){ IntentIntegrator integrator = new IntentIntegrator(this); integrator.setDesiredBarcodeFormats

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 the barcode using the ResultPoints array? After a bit of research I found the class
