nativescript-dynamsoft-barcode-reader

Nativescript 插件，用于 Dynamsoft Barcode Reader.

我们可以用它从摄像头帧或静态图像等来源读取条形码。

安装

npm install nativescript-dynamsoft-barcode-reader

使用

初始化

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

解码

1. 从摄像头帧解码

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

2. 使用 Dynamsoft Camera Enhancer 开始实时扫描。

   //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();
