Program.cs:
C#
using System; using Bytescout.BarCodeReader; namespace BarcodesFromPDF { class Program { static void Main() { Reader reader = new Reader(); reader.RegistrationName = "demo"; reader.RegistrationKey = "demo"; // Limit search to 1-dimensional barcodes only (exclude 2D barcodes to speed up the processing). // Change to barcodeReader.BarcodeTypesToFind.SetAll() to scan for all supported 1D and 2D barcode types // or select specific type, e.g. barcodeReader.BarcodeTypesToFind.PDF417 = True reader.BarcodeTypesToFind.All1D = true; // Input filename string fileName = "example.pdf"; // Pages from which barcodes to be fetched int[] readFromPages = { 1, 2 }; foreach (var pageNo in readFromPages) { Console.WriteLine("\n\nReading barcodes from PDF page {0}...", pageNo); // Decoding barcodes from PDF on page-by-page basis instead of reading whole page FoundBarcode[] barcodes = reader.ReadFrom(fileName, (pageNo - 1)); // Found results foreach (FoundBarcode barcode in barcodes) { Console.WriteLine("Found Barcode, Type: '{0}', Value: '{1}', Position: {2}", barcode.Type, barcode.Value, barcode.Rect); } } // Cleanup reader.Dispose(); Console.WriteLine(); Console.WriteLine("Press any key to continue."); Console.ReadKey(); } } }
