Decoding barcodes from PDF by pages - C#

BarCode Reader SDK sample in C# demonstrating ‘Decoding barcodes from PDF by pages’

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

            Console.WriteLine("Press any key to continue.");
