BarcodeDetector()

The BarcodeDetector() constructor creates a new BarcodeDetector object which detects linear and two-dimensional barcodes in images.

var BarcodeDetector = new BarcodeDetector();

barcodeDetectorOptions Optional

An options object containing a series of BarcodeFormats to search for in the subsequent detect() calls. The options are:

• formats: An Array of barcode formats as strings. To see a full list of supported formats see the Barcode Detection API overview page.

This example creates a new barcode detector object, with specified supported formats and tests for browser compatibility.

// create new detector
var barcodeDetector = new BarcodeDetector({formats: ['code_39', 'codabar', 'ean_13']});

// check compatibility
if (barcodeDetector) {
  console.log('Barcode Detector supported!');
} else {
  console.log('Barcode Detector is not supported by this browser.');
}
