// Load the document containing barcodes using the Parser class
using (Parser parser = new Parser("input.pdf")) {

    // Verify that the file supports barcode extraction
    if (!parser.Features.Barcodes) {
        Console.WriteLine("Barcode extraction is not supported");
        return;
    }

    // Retrieve and process the extracted barcodes
    IEnumerable<PageBarcodeArea> barcodes = parser.GetBarcodes();

    foreach (PageBarcodeArea barcode in barcodes) {
        Console.WriteLine("Page: " + barcode.Page.Index.ToString());
        Console.WriteLine("Value: " + barcode.Value);

How to extract barcodes from a PDF using barcode options

This example demonstrates how to extract barcodes from a PDF file using specific barcode extraction options.

C#

//  Load the PDF file with the Parser class
using (Parser parser = new Parser("input.pdf"))
{
    // Confirm barcode extraction is supported
    if (!parser.Features.Barcodes)
    {
        return;
    }

    // Use barcode options to filter results
    BarcodeOptions options = new BarcodeOptions(QualityMode.Low, QualityMode.Low, "QR");

    // Retrieve barcode data from the document
    IEnumerable<PageBarcodeArea> barcodes = parser.GetBarcodes(options);

    // Process the list of extracted barcodes
    foreach (PageBarcodeArea barcode in barcodes)
    {
        Console.WriteLine("Page: " + barcode.Page.Index.ToString());
