BarcodeTracking#
class BarcodeTracking : DataCaptureMode

Added in version 6.2.0

Data capture mode that implements MatrixScan (barcode tracking).

Learn more on how to use barcode tracking in our Get Started With MatrixScan guide.

This capture mode uses the barcode scanning and tracking capabilities. It cannot be used together with other capture modes that require the same capabilities, e.g. BarcodeCapture.

forContext(context, settings)#
static forContext(context: DataCaptureContext | null,
        settings: BarcodeTrackingSettings): BarcodeTracking

Added in version 6.2.0

Constructs a new barcode tracking mode with the provided context and settings. When the context is not null, the capture mode is automatically added to the context.

isEnabled#
isEnabled: boolean

Added in version 6.2.0

Implemented from DataCaptureMode. See DataCaptureMode.isEnabled.

applySettings(settings)#
applySettings(settings: BarcodeTrackingSettings): Promise<void>

Added in version 6.2.0

Asynchronously applies the new settings to the barcode scanner. If the scanner is currently running, the task will complete when the next frame is processed, and will use the new settings for that frame. If the scanner is currently not running, the task will complete as soon as the settings have been stored and won’t wait until the next frame is going to be processed.

addListener(listener)#
addListener(listener: BarcodeTrackingListener): void

Added in version 6.2.0

Adds the listener to observe this barcode capture instance.

If the listener is already observing the barcode tracking instance, calling this method has no effect.

removeListener(listener)#
removeListener(listener: BarcodeTrackingListener): void

Added in version 6.2.0

Removes a previously added listener from this barcode tracking instance.

If the listener is not currently observing the barcode tracking instance, calling this method has no effect.

recommendedCameraSettings()#
static get recommendedCameraSettings(): CameraSettings

Added in version 6.2.0

Returns the recommended camera settings for use with barcode tracking.

context#
get context(): DataCaptureContext | null

Added in version 6.2.0

Implemented from DataCaptureMode. See DataCaptureMode.context.
