class MaxiBarcodeReadOptions(BarcodeReadOptions):

Remarks

The MaxiBarcodeReadOptions class is used to control the options when reading Maxi 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.Maxi. Then change the members of the returned MaxiBarcodeReadOptions by casting it from BarcodeReadOptions to MaxiBarcodeReadOptions.

It is also possible to create an instance of the MaxiBarcodeReadOptions class and use it directly in 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.Maxi

In addition to these features and members, MaxiBarcodeReadOptions contains these Maxi barcodes specific features:

Member	Description
FriendlyName	Gets the friendly name of this class.
