Remarks

DocumentBarcodes manages the global barcodes settings of the document. It can be accessed through the Barcodes property of LEADDocument.

DocumentBarcodes contains the following:

BarcodeEngine: The engine to use when reading barcdoes.

The DocumentPage.ReadBarcodes method is used to read the barcodes of a page. The document will check if the value in BarcodeEngine is not null, if so, it will try to read the barcodes based on options set in BarcodeReader.

For more information, refer to Barcode processing with the Document Library.

   using (var document = DocumentFactory.LoadFromFile(Path.Combine(LEAD_VARS.ImagesDir, "Barcode1.tif"), options)) 
   { 
      // Setup a barcode reader object 
      var barcodeEngine = new BarcodeEngine(); 
      // Optionally, setup the reader option. Here we instruct the barcode reader to read all types of barcodes 
      barcodeEngine.Reader.ImageType = BarcodeImageType.Unknown; 
      // Set this engine to be used with the document 
      // DocumentBarcodes reference

      // Read all the barcodes in the first page 
      var page = document.Pages[0];
