Barcode Capture Settings

Defined under the namespace Scandit.Datacapture.Barcode

class BarcodeCaptureSettings

Added in version 6.13.0

Holds all the barcode recognition related settings, such as enabled symbologies and location selection. For the settings to take effect, they must be applied to a barcode capture instance using BarcodeCapture.applySettings().

By default, all types of barcodes (symbologies) are disabled. To scan barcodes, you need to manually enable all the symbologies you want to scan in your application.

The following lines of code show how to enable Symbology.Code128 and apply the settings to barcode capture.

const settings = new SDCBarcode.BarcodeCaptureSettings();
settings.enableSymbology(SDCBarcode.Symbology.Code128, true);

Added in version 6.13.0

Creates new default settings instance. Recognition is setup for recognizing codes in the full image. Symbologies are all disabled. Before passing the settings to the BarcodeCapture instance, make sure to enable the symbologies required by your application.

settingsForSymbology(symbology: Symbology): SymbologySettings

Added in version 6.13.0

Get SymbologySettings specific for the given Symbology.

Note that modifying the returned object doesn’t automatically apply the changes to BarcodeCapture. After you made changes to the symbology settings, call BarcodeCapture.applySettings() with these BarcodeCaptureSettings to apply them.

setProperty(name, value)
setProperty(name: string,
        value: any): void

Added in version 6.13.0

Sets a property to the provided value. Use this method to set properties that are not yet part of a stable API. Properties set through this method may or may not be used or change in a future release.

getProperty(name: string): any

Added in version 6.13.0

Retrieves the value of a previously set property. In case the property does not exist, -1 is returned.

codeDuplicateFilter: number

Added in version 6.13.0

Determines the time interval in which codes with the same symbology/data are filtered out as duplicates. By default, when the same code (data, symbology) is scanned in consecutive frames, it is reported again as a new scan. Use this property to change the interval or completely turn off duplicate filtering:

  • Setting this property to value smaller than zero, means that the same code will not be reported again until the scanning has been stopped.

  • Setting this property to a value of zero means that the same code will be reported every time it is found.

  • Setting this property to a value larger than zero indicates the time that must pass between the same code to be reported again.

The filtering is reset any time the capture mode is disabled (DataCaptureMode.setEnabled() called with False) as this is when the session is cleaned and restarts from zero.

get enabledSymbologies(): Symbology[]

Added in version 6.13.0

Returns the set of enabled symbologies.

enableSymbology(symbology, enabled)
enableSymbology(symbology: Symbology,
        enabled: boolean): void

Added in version 6.13.0

Provides a convenient shortcut to enable/disable decoding of a particular symbology without having to go through SymbologySettings.

Some 1d barcode symbologies allow you to encode variable-length data. By default, the Scandit Data Capture SDK only scans barcodes in a certain length range.

If your application requires scanning of one of these symbologies, and the length is falling outside the default range, you may need to adjust the active symbol counts for the symbology in addition to enabling it.

enableSymbologies(symbologies: Symbology[]): void

Added in version 6.13.0

Provides a convenient shortcut to enable decoding of particular symbologies without having to go through SymbologySettings. By default, all symbologies are turned off and symbologies need to be explicitly enabled.

enableSymbologiesForCompositeTypes(compositeTypes: CompositeType[]): void

Added in version 6.13.0

Enables all symbologies needed for the given composite types. To enable composite codes scanning it is also needed to enable the composite types through enabledCompositeTypes. By default, all symbologies are turned off and symbologies need to be explicitly enabled.

enabledCompositeTypes: CompositeType[]

Added in version 6.13.0

The enabled composite types. To enable composite codes scanning it is also needed to enable the symbologies that make up the specific type of composite code through enableSymbologiesForCompositeTypes().

locationSelection: LocationSelection | null

Added in version 6.13.0

Defines the strategy with which to select one out of many visible barcodes. See Location Selection Guide. By default, this property is null and code selection is disabled.

scanIntention?: ScanIntention

Added in version 6.24.0

The scan intention algorithm to use with BarcodeCapture. Defaults to ScanIntention.Manual, ensuring the standard performance with no smart algorithms. Set to ScanIntention.Smart to enable the automatic algorithm that intelligently identifies and then scans the barcode that the user intends to capture, reducing errors.
