Extract barcodes from document Leave feedback

GroupDocs.Parser provides the functionality to extract barcodes from documents by the GetBarcodes method:

IEnumerable<PageBarcodeArea> GetBarcodes();

This method returns a collection of PageBarcodeArea objects:

Here are the steps to extract all barcodes from the whole document:

• Instantiate Parser object for the initial document;
• Check if the document supports barcodes extraction;
• Call GetBarcodes method and obtain collection of PageBarcodeArea objects;
• Iterate through the collection and get a barcode value.

The following example shows how to extract barcodes from a document:

// Create an instance of Parser class
using (Parser parser = new Parser(Constants.SamplePdfWithBarcodes))
{
    // Check if the document supports barcodes extraction
    if (!parser.Features.Barcodes)
    {
        Console.WriteLine("Document doesn't support barcodes extraction.");
        return;
    }

    // Extract barcodes from the document.
    IEnumerable<PageBarcodeArea> barcodes = parser.GetBarcodes();

    // Iterate over barcodes
    foreach (PageBarcodeArea barcode in barcodes)
    {
        // Print the page index
        Console.WriteLine("Page: " + barcode.Page.Index.ToString());
        // Print the barcode value
        Console.WriteLine("Value: " + barcode.Value);
    }
}
