# BarcodeFormatGs1CompositeConfiguration class

GS1 Composite configuration. Add to scanner configuration to scan GS1 Composite barcodes.

When not enabled, the individual parts of GS1 Composite barcodes will be returned as separate items, if the respective formats are enabled (UPC-A, Code 128, MicroPDF417, PDF417). Those barcode items will have their isGS1CompositePart field set to true. If GS1 Composite scanning is enabled, the individual parts are never returned, even if their respective formats are enabled, except when the linear component is a UPC or EAN barcode. In that case the linear component might still occasionally be returned as a separate result. If this situation needs to be avoided, remove the UPC and EAN formats from the enabled formats.

If GS1 Composite scanning is disabled, but GS1 message validation is enabled, then the parts of the composite barcode may fail validation and be rejected.

## Constructors

BarcodeFormatGs1CompositeConfiguration.new({String regexFilter = "", double minimumSizeScore = 0.0, bool addAdditionalQuietZone = false, int minimum1DQuietZoneSize = 6, Gs1Handling gs1Handling = Gs1Handling.PARSE, bool strictMode = true})

## Properties

addAdditionalQuietZone ↔ bool
  If true, we process the barcode scanning with an artificial quiet zone that we add to the input image. This flag should be used to scan sharp crops of a barcode in single-shot mode.
  getter/setter pair inherited
gs1Handling ↔ Gs1Handling
  GS1 message handling options.
  getter/setter pair
hashCode → int
  The hash code for this object.
  no setter inherited
minimum1DQuietZoneSize ↔ int
  Minimum quiet zone size on the left and right sides of a 1D barcode, measured in number of modules. The quiet zone is only for 1D barcodes with weak start/stop patterns, i.e. Iata2Of5, Industrial2Of5, Code25, Itf, Codabar, MsiPlessey and Code11.
  getter/setter pair
minimumSizeScore ↔ double
  Minimum acceptable value of a result BarcodeItem's sizeScore (between 0 and 1). Barcodes with a sizeScore less than this value will not be scanned. When set to 0, barcodes are returned no matter what their size is.
  getter/setter pair inherited
regexFilter ↔ String
  Regular expression filter for barcode text. If the barcode text does not match the regular expression, it will not be scanned. The default is an empty string (setting is turned off).
  getter/setter pair inherited
runtimeType → Type
  A representation of the runtime type of the object.
  no setter inherited
strictMode ↔ bool
  If true, the barcode scanner will only return barcodes that pass the strict validation checks according to standards to avoid false positives.
  getter/setter pair

## Methods

noSuchMethod(Invocation invocation) → dynamic
  Invoked when a nonexistent method or property is accessed.

## Operators
