Text Capture#

Defined in namespace Scandit.Datacapture.Text

TextCapture#
class TextCapture : IDataCaptureMode

Added in version 6.5.0

Capture mode for reading text.

Create()#
static TextCapture Create(DataCaptureContext context, TextCaptureSettings settings)

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.

FromJson()#
static TextCapture FromJson(DataCaptureContext context, string jsonData)

Added in version 6.5.0

Construct a new text capture mode with the provided JSON serialization. See Serialization for details. The capture mode is automatically added to the context.

Enabled#
bool Enabled { get;set; }

Added in version 6.5.0

Implemented from IDataCaptureMode. See IDataCaptureMode.Enabled.

PointOfInterest#
PointWithUnit PointOfInterest { get;set; }

Added in version 6.5.0

The point of interest overwriting the point of interest of the data capture view. By default, this overwriting point of interest is not set and the one from the data capture view is used.

The overwriting point of interest is used to control the center of attention for the following subsystems:

  • Location selection. When no location selection is set, the point of interest defines the location at which the recognition optimizes for reading barcodes.

  • Rendered viewfinders.

ApplySettingsAsync()#
Task ApplySettingsAsync(TextCaptureSettings settings)

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#
TextCaptureFeedback Feedback { get;set; }

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.

TextCapture textCapture = ...;
textCapture.Feedback.Success = new Feedback(Vibration.DefaultVibration, Sound.DefaultSound);
AddListener()#
void AddListener(ITextCaptureListener listener)

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()#
void RemoveListener(ITextCaptureListener listener)

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.

RecommendedCameraSettings#
static CameraSettings RecommendedCameraSettings { get; }

Added in version 6.5.0

Returns the recommended camera settings for use with text capture.

Context#
DataCaptureContext Context { get; }

Added in version 6.5.0

Implemented from IDataCaptureMode. See IDataCaptureMode.Context.

UpdateFromJson()#
void UpdateFromJson(string jsonData)

Added in version 6.5.0
