Public Interface IBarcodeReadOptions  
   Inherits Leadtools.Barcode.IBarcodeOptions

public interface IBarcodeReadOptions : Leadtools.Barcode.IBarcodeOptions

function Leadtools.Barcode.IBarcodeReadOptions() Leadtools.Barcode.IBarcodeOptions

public interface class IBarcodeReadOptions : public Leadtools.Barcode.IBarcodeOptions

Remarks

Note: In LEADTOOLS for .NET, the equivalent to this interface is the BarcodeReadOptions class.

The BarcodeReader class contains multiple methods to read a single or multiple barcodes from an image ( Refer to the BarcodeReader.ReadBarcode and BarcodeReader.ReadBarcodes methods). For each barcode found, BarcodeReader will return an instance of BarcodeData populated with the data found in the barcode.

The clases that implements IBarcodeReadOptions interface is used to control the options used when reading a barcode using LEADTOOLS. You can 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 the symbology of interest. You can then change the members of the returned IBarcodeReadOptions (or after casting it to the appropriate derived class).

You can also create an instance of one of the derived IBarcodeReadOptions classes and use it directly in the BarcodeReader.ReadBarcode and BarcodeReader.ReadBarcodes methods that accepts a single or array of options as an input parameter.

The IBarcodeReadOptions contains the following members and features:

Member	Description
IBarcodeReadOptions.ForeColor	Controls the barcode foreground color (color of the bars or symbols) to use when reading a barcode from a colored image.
IBarcodeReadOptions.BackColor	Controls the barcode background color (color of the spaces) to use when reading a barcode from a colored image.

IBarcodeReadOptions is an interface and cannot be created directly, instead create one of these classes that implements it:

Read options class	Descriptions
OneDBarcodeReadOptions	Standard 1D linear barcode options. Used when reading any of the following symbologies: EAN13, EAN8, UPCA, UPCE, Code3Of9, Code128, CodeInterleaved2Of5, Codabar, UCCEAN128, Code93, EANEXT5, EANEXT2, MSI, Code11, CodeStandard2Of5, GS1Databar, GS1DatabarLimited or GS1DatabarExpanded
GS1DatabarStackedBarcodeReadOptions	GS1 Databar stacked barcode options. Used when reading GS1DatabarStacked or GS1DatabarExpandedStacked symbologies
FourStateBarcodeReadOptions	4-State barcode options. Used when reading AustralianPost4State, RoyalMail4State or USPS4State symbologies
