Tried QuaggaJS library, it reads the image fine, but the onProcessed in never called for the types of images I am trying. QuaggaJS is a barcode-scanner entirely written in JavaScript supporting real-time localization and decoding of various types of barcodes such as EAN,CODE 128, CODE 39, EAN 8, UPC-A, UPC-C, I2of5,2of5, CODE 93 and CODABAR. Can use a jQuery/JS library or something in PHP that would send the image and get the Code as output. Feature-detection of getUserMediaĮvery browser seems to differently implement the mediaDevices.getUserMediaĪPI. Looking for a BarCode scanner for a website. Hostnames need to be served via You can find more information in theĬhrome M47 WebRTC Release Notes. Important: Accessing getUserMedia requires a secure origin in mostīrowsers, meaning that can only be used on localhost. The following APIs need to be implemented in your browser: Requires the presence of the MediaDevices API. using a camera to decode the images from a live-stream. There are two modes in which Quagga operates: 1. Quagga makes use of many modern Web-APIs which are not implemented by allīrowsers yet. Invariant to scale and rotation, whereas other libraries require the barcode toīe aligned with the viewport. Is capable of finding a barcode-like pattern in an image resulting in anĮstimated bounding box including the rotation. Regardless of the plethora of features this library offers, in this article I’m going to focus on the live streaming of the device camera to read the barcode image. This implementation features a barcode locator which QuaggaJS is a javascript library project maintained by Christoph Oberhofer, that allows devices to use their cameras as barcode scanners, both in static and live images. This is not yet another port of the great zxing library, but If you want to dive deeper into this topic. The blog post ( How barcode-localization works in QuaggaJS) Locating and decoding barcodes in real-time.
Although theĬode relies on heavy image-processing even recent smartphones are capable of GetUserMedia to get direct access to the user's camera stream. Time localization and decoding of various types of barcodes such as EAN,ĬODE 128, CODE 39, EAN 8, UPC-A, UPC-C, I2of5,Ģof5, CODE 93 and CODABAR.

I can only run this app on fiori client(App deployed on SAP Portal).Ĭordova-barcode-scan-plugin-issue-on-scp-portal.jpgĢ. I don't understand why the difference in behavior when the code is same across both services. cordova is being detected on web ide (index.html run), but it is not available on Portal Service.
