nativescript-dynamsoft-barcode-reader

Nativescript plugin for Dynamsoft Barcode Reader.

We can use it read barcodes from sources like the camera frames or static images.

Installation

npm install nativescript-dynamsoft-barcode-reader

Usage

Initialization

this.dbr = new BarcodeReader();
this.dbr.initLicense("DLS2eyJoYW5kc2hha2VDb2RlIjoiMjAwMDAxLTE2NDk4Mjk3OTI2MzUiLCJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSIsInNlc3Npb25QYXNzd29yZCI6IndTcGR6Vm05WDJrcEQ5YUoifQ=="); //1-day public trial.

Decoding

1. Decode from a camera frame

   let results = this.dbr.decodeFrame(this.dce.captureFrame()); //get a camera frame from Dynamsoft Camera Enhancer

2. Start live scanning with Dynamsoft Camera Enhancer.

   //bind Dynamsoft Camera Enhancer to Dynamsoft Barcode Reader
   this.dbr.setCameraEnhancer(this.dce.getCameraEnhancer()); 
   //set the text result listener
   this.dbr.setTextResultListener(function (textResults:TextResult[]) {
     console.log(textResults);
   })
   //start scanning from the camera
   this.dbr.startScanning();
