You can use LEADTOOLS Barcode SDK technology in your application. https://www.leadtools.com/sdk/barcode You can leverage the BarcodeEngine class, to write, detect, and extract barcode information from any of the LEADTOOLS supported barcode types, including QR. Here is some sample code: // Load image with barcode using (RasterCodecs codecs = new RasterCodecs) using (RasterImage image = codecs.Load(@ "IMAGE FILE PATH" )) { // initialize BarcodeEngine and Reader BarcodeEngine barcodeEngine = new BarcodeEngine(); BarcodeReader barcodeReader = barcodeEngine.Reader; // Passing LeadRect as empty searches the entire PDF for the barcode BarcodeData data = barcodeReader.ReadBarcode(image, LeadRect.Empty, BarcodeSymbology.QR); // Output barcode data Console.WriteLine($ "Barcode Symbology: {data.Symbology}
Barcode Value: {data.Value}
Barcode Bounds: {data.Bounds}" ); }
