class GS1DatabarStackedBarcodeWriteOptions(BarcodeWriteOptions):

Remarks

The GS1DatabarStackedBarcodeWriteOptions class is used to control the options when writing GS1 Databar Stacked 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:

. Change the members of the returned GS1DatabarStackedBarcodeWriteOptions by casting it from BarcodeWriteOptions to GS1DatabarStackedBarcodeWriteOptions.

Create an instance of GS1DatabarStackedBarcodeWriteOptions 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 following symbologies: BarcodeSymbology.GS1DatabarStacked and BarcodeSymbology.GS1DatabarExpandedStacked

In addition to these features and members, GS1DatabarStackedBarcodeWriteOptions contains these GS1 Databar Stacked barcodes specific features:

Member	Description
UseXModule	Use the XModule when writing barcodes of this type
XModule	The size of the smallest module when writing a GS1 Databar Stacked barcode
SetLinkageBit	Set the linkage bit when writing the barcode
UseStackedOmniDirectionalFormat	Use two-row in Stacked Omni-directional format when writing the barcode
ExpandedStackedRowsCount	Number of rows to write for GS1 Databar Expanded Stacked format
