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

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 Documents Library.
