Deprecation warning

Please note that this is outdated documentation for an older release of the Scandit Barcode Scanner SDK.

We are deprecating the 5.x API on all platforms (except Linux). Release 5.19 in April 2021 will be our final. Applications running 5.x will continue to work, and we will continue to release critical bug fixes and security patches only, for one year. We encourage you to migrate to 6.x and take advantage of our latest / advanced features and improved performance.

You'll find the updated documentation at: Data Capture SDK Documentation for Xamarin.Android and Data Capture SDK Documentation for Xamarin.iOS

Detailed Description

Contains settings that affect the decoding of a specific symboloy.

The symbology settings class holds all settings that apply to a certain barcode symbology, such as whether the symbology is enabled, the enabled checksums etc.

Since
4.7.0

Member Function Documentation

void SetExtensionEnabled ( String  extension,
boolean  enabled 
)

Activate/Deactivate a custom extension for the symbology.

Extensions are custom features that are only supported by a small number of symbologies. For a list of supported extensions, consult the constants of this class.

Parameters
extensionName of the extension.
enabledWhether the extension should be enabled/disabled.
Since
4.7.0
boolean IsExtensionEnabled ( String  extension)

Determine whether a certain extension is enabled for the symbology.

Extensions are custom features that are only supported by a small number of symbologies. For a list of supported extensions, consult the constants of this class.

Parameters
extensionName of the extension.
Returns
True if the extension is enabled, false if not.
Since
4.7.0
short [] GetActiveSymbolCounts ( )

Control the length of barcodes to be decoded.

Change this property enable decoding of long codes which can not be decoded with the default settings, or to optimize decoder performance for codes of certain lengths. This is useful when it is known that the application only requires scanning of particular barcode lengths.

The mapping from characters to symbols is symbology-specific. For some symbologies, the start and end characters are included, others include checksums characters in the symbol counts.

The active symbol count setting is ignored for fixed-size barcodes (the EAN and UPC family of codes) as well as 2d codes. For other symbologies, see Calculating symbol counts for variable-length symbologies.

Returns
array of enabled active symbol counts.
Since
4.8.0
void SetActiveSymbolCounts ( short[]  counts)

Change the length of barcodes to be decoded.

GetActiveSymbolCounts
Parameters
countsList of new active symbol counts to use.
Since
4.8.0

Member Data Documentation

final int ChecksumNone
static

No optional checksum.

final int ChecksumMod10
static

Modulo 10 checksum.

final int ChecksumMod11
static

Modulo 11 checksum.

final int ChecksumMod47
static

Modulo 47 checksum.

final int ChecksumMod43
static

Modulo 43 checksum.

final int ChecksumMod103
static

Modulo 103 checksum.

final int ChecksumMod1010
static

Two modulo 10 checksums.

final int ChecksumMod1110
static

A modulo 11 and a modulo 10 checksum.

final String ExtensionTiny
static

Enable decoder optimizations for small data-matrix codes.

final String ExtensionFullAscii
static

Full-ASCII Code39 extension.

final String ExtensionRemoveLeadingZero
static

Remove leading zero of UPCA codes.

When enabled, the leading zero of UPCA codes is removed. When false (the default), the leading zero is returned as part of the barcode data string

boolean Enabled

Whether decoding of this symbology is enabled.

This property only enables/disables decoding of dark codes on bright background. If color- inverted (bright on dark) codes for this symbology are required, enable them through the colorInvertedEnabled property. By default decoding of all symbologies is disabled.

It is advised to only enable symbologies that are required by the application as every enabled symbology adds processing overhead.

Since
4.7.0
boolean ColorInvertedEnabled

Whether color-inverted decoding of this symbology is enabled.

This property only enables/disables decoding of bright codes on dark background. By default color-inverted decoding of all symbologies is disabled.

It is advised to only enable symbologies that are required by the application as every enabled symbology adds processing overhead.

Since
4.7.0
int Checksums

Get active optional checksums for this symbology.

This property contains the additional checksums for this symbology. When a barcode has been decoded, the checksums contained are evaluated in addition to any mandatory checksum defined by the symbology specification. If any of the checksums matches, the code is returned as recognized, otherwise it is discarded.

At the moment, only one optional checksum is supported. This might change for future versions.

Since
4.7.0
readonly int Symbology

The symbology these symbology settings apply to.
