Detection on the Image | Cordova Barcode Scanner

Barcode Detection from Still Images​

ScanbotBarcodeSDK.detectBarcodesOnImage(successCallback, errorCallback, args) This method provides the functionality of detecting barcodes from a still image, e.g. a JPG image from a Photo Library or other source. The image must be passed as a file URI.

Arguments:

  • imageFileUri - A valid file URI of the image (e.g. file:///some/path/image-with-barcodes.jpg). Supported image formats are JPG and PNG. Please make sure your app has the read permission to access this file.

Result:

  • result.data?.barcodes - Optional List of recognized barcodes as items. Same structure as in the startBarcodeScanner result.
