The PDF417BarcodeReadOptions class is used to control the options when reading PDF417 barcodes using LEADTOOLS. Set the options in two ways:

The BarcodeReader class contains default options for each barcode symbology (or group of common symbologies). These options can be retrieved using the BarcodeReader.GetDefaultOptions method passing BarcodeSymbology.PDF417. Then change the members of the returned PDF417BarcodeReadOptions by casting it from BarcodeReadOptions to PDF417BarcodeReadOptions.

You can also create an instance of the PDF417BarcodeReadOptions class and use it directly in the BarcodeReader.ReadBarcode and BarcodeReader.ReadBarcodes methods that accept a single or array of options as an input parameter.

The base BarcodeReadOptions contains the following members and features:

Member Description

Controls the barcode foreground color (color of the bars or symbols) to use when reading a barcode from a colored image.


Controls the barcode background color (color of the spaces) to use when reading a barcode from a colored image.

BarcodeReadOptions.Load and BarcodeReadOptions.Save

Can be used to save or load the options to/from an XML file or stream.


This class overrides the base class method to return an array containing the following symbologies: BarcodeSymbology.PDF417
