Remarks

The BarcodeWriter class contains the BarcodeWriter.WriteBarcode method which is used to write a barcode to an image. You must create an instance of BarcodeWriter, fill its members with the barcode properties and pass it to this method.

The BarcodeWriteOptions class and its derived types is used to control the options used when writing a barcode using LEADTOOLS. You can 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 the symbology of interest. You can then change members of the returned BarcodeWriteOptions (or after casting it to the appropriate derived class).

You can also create an instance of one of the derived BarcodeWriteOptions classes and use it directly in the BarcodeWriter.WriteBarcode method which accepts the options as an input parameter.

The 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 and BarcodeWriteOptions.IsSupportedSymbology	Can be used to get all the BarcodeSymbology's supported by this BarcodeWriteOptions type or to check when a particular symbology is supported.

BarcodeWriteOptions is an abstract class and cannot be created directly, instead create one of the these derived classes:

Write options class	Descriptions
OneDBarcodeWriteOptions	Standard 1D linear barcode options. Used when writing any of the following symbologies: EAN13, EAN8, UPCA, UPCE, Code3Of9, Code128, CodeInterleaved2Of5, Codabar, UCCEAN128, Code93, EANEXT5, EANEXT2, MSI, Code11, CodeStandard2Of5, GS1Databar, GS1DatabarLimited or GS1DatabarExpanded
GS1DatabarStackedBarcodeWriteOptions	GS1 DataBar Stacked barcode options. Used when writing GS1DatabarStacked or GS1DatabarExpandedStacked symbologies
FourStateBarcodeWriteOptions	4-State barcode options. Used when writing AustralianPost4State, RoyalMail4State or USPS4State symbologies
PostNetPlanetBarcodeWriteOptions	POSTNET/Planet barcode options. Used when writing PostNet or Planet symbologies
PatchCodeBarcodeWriteOptions	Patch code barcode options. Used when writing PatchCode symbology.
DatamatrixBarcodeWriteOptions	Datamatrix barcode options. Used when writing Datamatrix symbology.
MicroPDF417BarcodeWriteOptions	Micro PDF417 barcode options. Used when writing MicroPDF417 symbology.
PDF417BarcodeWriteOptions	PDF417 barcode options. Used when writing PDF417 symbology.
QRBarcodeWriteOptions	QR barcode options. Used when writing QR symbology.
AztecBarcodeWriteOptions	Aztec barcode options. Used when writing Aztec symbology.
MaxiBarcodeWriteOptions	Maxi barcode options. Used when writing Maxi symbology.
MicroQRBarcodeWriteOptions	MicroQR barcode options. Used when writing MicroQR symbology.
PharmaCodeBarcodeWriteOptions	PharmaCode barcode options. Used when writing PharmaCode symbology.

Example

This example sets the "Use X Module" option of all supported symbologies to be "true" and then creates TIFF files of all the supported barcodes.
