GS1DatabarStackedBarcodeReadOptions Class

Contains the extra options to use when reading GS1 Databar Stacked barcodes.

class GS1DatabarStackedBarcodeReadOptions(BarcodeReadOptions): 

The GS1DatabarStackedBarcodeReadOptions class is used to control the options when reading GS1 Databar Stacked 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 one of the following:

Change the members of the returned GS1DatabarStackedBarcodeReadOptions by casting it from BarcodeReadOptions to GS1DatabarStackedBarcodeReadOptions.

It is also possible to create an instance of the GS1DatabarStackedBarcodeReadOptions class and use it directly in the BarcodeReader.ReadBarcode and BarcodeReader.ReadBarcodes methods that accept a single or an array of options as an input parameter.

The base BarcodeReadOptions contains the following members and features:

Member Description

Controls the barcode foreground color (color of the bars or symbols) to use when reading a barcode from a colored image.


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.


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, GS1DatabarStackedBarcodeReadOptions contains these GS1 Databar Stacked barcodes specific features:

Member Description

The direction to use when searching for barcodes (horizontal, vertical or both)


Fast barcode reading (recommended). It is suitable for most barcode qualities: either good or poor


The number of scanned lines per column to skip when reading a barcode


The error check digit is returned as part of the barcode data


This example writes a few GS1 Databar Stacked barcodes with different options to an image and then reads them back.
