TextCapture

class TextCapture : DataCaptureMode

Added in version 6.5.0

Deprecated since version 6.26.0.

Capture mode for reading text.

forContext(context, settings)

static forContext(context: DataCaptureContext | null,
        settings: TextCaptureSettings): TextCapture

Added in version 6.5.0

Construct a new text capture mode with the provided context and settings. Then 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: TextCaptureSettings): Promise<void>

Added in version 6.5.0

Asynchronously apply the new settings to the text capture mode. If text capture is currently running, the task will complete when the next frame is processed, and will use the new settings for that frame. If text capture 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.

feedback

feedback: TextCaptureFeedback

Added in version 6.5.0

Instance of TextCaptureFeedback that is used by text capture to notify users about Success events.

The default instance of the Feedback will have both sound and vibration enabled. A default beep sound will be used for the sound.

To change the feedback emitted, the TextCaptureFeedback can be modified as shown below, or a new one can be assigned.

const textCapture = ...;
const feedback = TextCaptureFeedback.defaultFeedback;
feedback.success = new Feedback(Vibration.defaultVibration, null);
textCapture.feedback = feedback;

addListener(listener)

addListener(listener: TextCaptureListener): void

Added in version 6.5.0

Add the listener to observe this text 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: TextCaptureListener): void

Added in version 6.5.0

Remove a previously added listener from this text capture instance.

In case the listener is not currently observing this instance, calling this method has no effect.
