Barcode Tracking
Defined under the namespace Scandit.Datacapture.Barcode.Tracking
- BarcodeTracking
class BarcodeTracking : DataCaptureMode
Added in version 6.5.0
Data capture mode that implements MatrixScan (barcode tracking).
Learn more on how to use barcode tracking in our Get Started 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 6.5.0
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 6.5.0
Implemented from DataCaptureMode. See DataCaptureMode.isEnabled.
- applySettings(settings)
applySettings(settings: BarcodeTrackingSettings): Promise<
void>Added in version 6.5.0
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.
Same as applySettings() with the second argument set to null.
- addListener(listener)
addListener(listener: BarcodeTrackingListener):
voidAdded in version 6.5.0
Adds the listener to observe this barcode capture instance.
In case the same listener is already observing this instance, calling this method will not add the listener again.
- removeListener(listener)
removeListener(listener: BarcodeTrackingListener):
voidAdded in version 6.5.0
Removes a previously added listener from this barcode tracking instance.
In case the listener is not currently observing this instance, calling this method has no effect.
- recommendedCameraSettings()
static get recommendedCameraSettings(): CameraSettings
Added in version 6.5.0
Returns the recommended camera settings for use with barcode tracking.
- context
get context(): DataCaptureContext | null
Added in version 6.5.0
Implemented from DataCaptureMode. See DataCaptureMode.context.
