How to Read Barcodes and QR Codes Using OCR in C#

// This code sample demonstrates the process of installing and using Iron OCR to read barcodes and QR codes from PDFs in C#.

// First, install Iron OCR via NuGet Package Manager:
// Use the Package Manager Console and run the following command:
// Install-Package IronOcr

// Import the IronOCR namespace
using IronOcr;

class Program
{
    static void Main()
    {
        // Set the license key for Iron OCR
        var Ocr = new IronTesseract();

        // Initialize the OCR engine
        // Setting the language to English
        Ocr.Language = OcrLanguage.English;

        // Load a PDF document and automatically recognize all barcodes and QR codes
        using (var input = new OcrInput())
        {
            // Load the PDF with the path to the document containing barcodes
            input.AddPdf("path_to_barcode_pdf.pdf");

            // Extract barcode content
            var results = Ocr.Read(input);

            // Print all recognized barcode and QR code data
            foreach (var barcode in results.Barcodes)
            {
                Console.WriteLine($"Type: {barcode.Type}, Value: {barcode.Value}");
            }
        }

        // Similarly, to extract QR codes from another PDF document, perform the following:
        using (var qrInput = new OcrInput())
        {
            // Load the PDF with the path to the document containing QR codes
            qrInput.AddPdf("path_to_qr_pdf.pdf");

            // Extract QR code content
            var qrResults = Ocr.Read(qrInput);

            // Print all recognized QR code data
            foreach (var qr in qrResults.Barcodes)
            {
                Console.WriteLine($"Type: {qr.Type}, Value: {qr.Value}");
            }
        }
    }
}
