 function Leadtools.Barcode.BarcodeReader.GetAllDefaultOptions()

public:
array<BarcodeReadOptions^>^ GetAllDefaultOptions();

Return Value

An array of BarcodeReadOptions derived types that contain all the default read options currently set in this BarcodeReader.

The BarcodeReader object contains an array of all the default read options used by the ReadBarcode and ReadBarcodes methods when no explicit options are passed by the user.

Refer to the BarcodeReadOptions class for a list of the symbologies and the type of the derived BarcodeReadOptions used by LEADTOOLS.

To get the options for a specific symbology, refer to GetDefaultOptions
