class OneDBarcodeWriteOptions(BarcodeWriteOptions):

Remarks

The OneDBarcodeWriteOptions class is used to control the options when standard 1D (linear) barcodes using LEADTOOLS. Set the options in two ways:

The BarcodeWriter class contains default options for each barcode symbology (or group of common symbologies). These options can be retrieved using the BarcodeWriter.GetDefaultOptions method passing one of the following:

. Then change the members of the returned OneDBarcodeWriteOptions by casting it from BarcodeWriteOptions to OneDBarcodeWriteOptions.

Also create an instance of one of OneDBarcodeWriteOptions class and use it directly in the BarcodeWriter.WriteBarcode method which accepts the options as an input parameter.

The base BarcodeWriteOptions contains the following members and features:

Member	Description
BarcodeWriteOptions.ForeColor	Controls the barcode foreground color (color of the bars or symbols) to use when writing a barcode to an image.
BarcodeWriteOptions.BackColor	Controls the barcode background color (color of the spaces) to use when writing a barcode to an image.
BarcodeWriteOptions.Load and BarcodeWriteOptions.Save	Can be used to save or load the options to/from an XML file or stream.
BarcodeWriteOptions.GetSupportedSymbologies	This class overrides the base class method to return an array containing the symbologies: BarcodeSymbology.EAN13, BarcodeSymbology.EAN8, BarcodeSymbology.UPCA, BarcodeSymbology.UPCE, BarcodeSymbology.Code3Of9, BarcodeSymbology.Code128, BarcodeSymbology.CodeInterleaved2Of5, BarcodeSymbology.Codabar, BarcodeSymbology.UCCEAN128, BarcodeSymbology.Code93, BarcodeSymbology.EANEXT5, BarcodeSymbology.EANEXT2, BarcodeSymbology.MSI, BarcodeSymbology.Code11, BarcodeSymbology.CodeStandard2Of5, BarcodeSymbology.GS1Databar, BarcodeSymbology.GS1DatabarLimited and BarcodeSymbology.GS1DatabarExpanded

In addition to these features and members, OneDBarcodeWriteOptions contains these standard 1D (linear) barcodes specific features:

Member	Description
TextPosition	The text position to use when the data string is written along with the barcode
EnableErrorCheck	Outputs the optional check word for validity check when writing a barcode (if supported)
UseXModule	Uses the XModule when writing barcodes of this type
XModule	The size of the smallest module when writing a barcode
SetGS1DatabarLinkageBit	Sets the linkage bit when writing GS1 Databar barcodes
WriteTruncatedGS1Databar	Writes truncated GS1 Databar symbols
Code128TableEncoding	Encoding table to use when writing Code 128 barcodes
Code11CheckDigitType	Check digit type to use when reading writing 11 (USD-8) barcodes
MSIModuloType	Check digit type to use when writing MSI (Pulse Width Modulated) barcodes
