If you have images that contain barcodes, you can add barcode scanning using the LEADTOOLS toolkit (https://www.leadtools.com/sdk/barcode). The Barcode SDK can detect, read, and write 1D and 2D barcodes in images. It is also integrated with the library's HTML5/JavaScript Document library which you can use in your ASP.NET project. The code to recognize barcodes in a document looks like this: function barcodesExample() { // Load a new document var url = "https://demo.leadtools.com/images/tiff/barcode.tif" ; console.log( "Loading document ..." ); var loadDocumentOptions = new lt.Documents.LoadDocumentOptions(); lt.Documents.DocumentFactory.loadFromUri(url, loadDocumentOptions) .done( function (doc) { console.log( "Done. Reading barcodes ..." ); // Read all the barcodes in the first page var docPage = doc.pages.item(0); docPage.readBarcodes(lt.LeadRectD.empty, 0, null ) .done( function (barcodes) { console.log( "Number of barcodes read " + barcodes.length); for ( var i = 0; i var barcodeData = barcodes[i]; console.log( " Symbology:" + barcodeData.symbology); console.log( " Bounds:" + barcodeData.bounds.x + "," + barcodeData.bounds.y + "," + barcodeData.bounds.width + "," + barcodeData.bounds.height); console.log( " Value:" + barcodeData.value); } }) .fail( function (jqXHR, statusText, errorThrown) { showServiceError(jqXHR, statusText, errorThrown); }); }) .fail( function (jqXHR, statusText, errorThrown) { showServiceError(jqXHR, statusText, errorThrown); }); }

Scan barcode from Images is fairly simple with Free Spire.Barcode library, you can get it from NuGet and then use this line of code to read barcode data: string [] data = Spire.Barcode.BarcodeScanner.Scan( "QRCode.png" , Spire.Barcode.BarCodeType.QRCode); Check the tutorial here for more information: https://www.e-iceblue.com/Tutorials/Spire.Barcode/Spire.Barcode-Program-Guide/How-to-Scan-Barcode-in-C.html
