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
BarcodeReadOptions.ForeColor	Controls the barcode foreground color (color of the bars or symbols) to use when reading a barcode from a colored image.
BarcodeReadOptions.BackColor	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.
BarcodeReadOptions.GetSupportedSymbologies	This class overrides the base class method to return an array containing the following symbologies: BarcodeSymbology.PDF417

In addition to these features and members, the PDF417BarcodeReadOptions contains these PDF417 barcodes specific features:

Member	Description
SearchDirection	The direction to use when searching for barcodes (horizontal, vertical or both)
EnableDoublePass	Enable internal auto preprocessing of the image data if no PDF417 barcode was found
EnableFastMode	Enable or disable fast PDF417 reading mode
ReadMode	The channel mode to use when reading PDF417 barcodes.
ReturnCorruptedSymbolArea	Instruct the engine to return the area where an un-readable PDF417 symbol is located (with no data).
ReadOptionalMacroFileNameField, ReadOptionalMacroSegmentCountField, ReadOptionalMacroTimestampField, ReadOptionalMacroSenderField, ReadOptionalMacroAddresseeField, ReadOptionalMacroFileSizeField, ReadOptionalMacroChecksumField and ReadOptionalMacro79AndAZField	Retrieve an optional macro field when reading PDF417 barcodes.
