You will need to use a programming SDK that supports both: loading images and reading QR barcodes features. For these purposes, you could try using LEADTOOLS .NET UWP features to support reading QR codes from images in your application. For example, the following lines of code load an image, try reading the QR barcodes and then reports the recognition results: private void _aboutToolStripMenuItem_Click( object sender, EventArgs e) { //using (AboutDialog aboutDialog = new AboutDialog("Barcode", ProgrammingInterface.CS)) // aboutDialog.ShowDialog(this); Leadtools.Barcode.BarcodeEngine engine = new Leadtools.Barcode.BarcodeEngine(); string imageFileName = @ "Add the location of the image that contains barcodes here." ; using (Leadtools.Codecs.RasterCodecs codecs = new Leadtools.Codecs.RasterCodecs()) { using (Leadtools.RasterImage image = codecs.Load(imageFileName)) { // Read all the QR barcodes ReadBarcodes(engine.Reader, image); } } } private void ReadBarcodes(BarcodeReader reader, RasterImage image) { // Setup read options QRBarcodeReadOptions options = new QRBarcodeReadOptions(); options.EnableDoublePass = false ; Console.WriteLine( "Reading QR barcodes" ); BarcodeData[] barcodes = reader.ReadBarcodes(image, LeadRect.Empty, 0, new BarcodeSymbology[] { BarcodeSymbology.QR }, new BarcodeReadOptions[] { options }); Console.WriteLine( "{0} barcodes found:" , barcodes.Length); foreach (QRBarcodeData barcode in barcodes) { string value = BarcodeData.ParseECIData(barcode.GetData()); if ( string .IsNullOrEmpty(value)) value = barcode.Value; Console.WriteLine( " At {0}, symbol model: {1} and data: {2}" , barcode.Bounds, barcode.SymbolModel, value); } } You can find more information here: https://www.leadtools.com/help/leadtools/v20/dh/ba/barcodereader.html
