How to Read Barcodes from Multi-Page/Frame GIF and TIFF

using IronBarCode; // Import the IronBarCode library
using System; // Import the System namespace for console operations

// Read barcodes from a TIFF image file
// This reads barcodes from the specified file 'sample.tif'
BarcodeResults results = BarcodeReader.Read("sample.tif");

// Output each barcode's value to the console
// Iterate over each result in the BarcodeResults collection
foreach (BarcodeResult result in results)
{
    // Print the value of the barcode to the console
    if (result != null) // Ensure result is not null to avoid runtime errors
    {
        Console.WriteLine(result.Value);
    }
    else
    {
        Console.WriteLine("No barcode detected.");
    }
}
