      Rectangle getScanningRegion()
      Returns the current scanning region or null if entire image is scanned.
      ScanResultListener getScanResultListener()
      Returns the listener that will obtain the results of the scanning.
      boolean isScanningPaused()
      Returns true if scanning is paused or if scanning still has not yet started.
      protected void onActivityFlip()
      Called when activity is flipped - this event is not raised by OS so we have custom detection of that state.
      protected void onCameraPreviewStarted()  
      protected void onCameraPreviewStopped()  
      void pause()
      This method must be called from activity's onPause.

      Called inside onCreate method before creating camera manager.
      void reconfigureRecognizers​(RecognizerBundle recognizerBundle)
      Use this method to reconfigure available recognizers.
      protected boolean requireAutofocusFeature()
      If autofocus feature is required, please return true from this method.
      void resetRecognitionState()
      Resets the recognition state, i.e.
      void resetRecognitionState​(boolean hardReset)
      Resets the recognition state.
      void resume()
      This method must be called from activity's onResume.
      void resumeScanning​(boolean resetState)
      This method resumes scanning loop that was paused by calling pauseScanning().
      void setFrameRecognitionCallback​(com.microblink.documentverification.view.recognition.FrameRecognitionCallback frameRecognitionCallback)
      Sets the frame recognition callback that will be invoked for each camera frame, after the recognition has been completed.
      void setLifecycle​(androidx.lifecycle.Lifecycle lifecycle)
      Sets lifecycle that will be observed so that you don't have to manually call create(), resume() and other lifecycle methods.
      void setMetadataCallbacks​(MetadataCallbacks metadataCallbacks)
      Sets the metadata callbacks that will obtain metadata during processing.
      void setRecognizerBundle​(RecognizerBundle recognizerBundle)
      Sets the recognizer bundle containing recognizers that will perform the recognition.
      void setScanningRegion​(Rectangle scanningRegion, boolean rotateRegionWithDevice)
      Define scanning region as a rectangle.
      void setScanResultListener​(ScanResultListener scanResultListener)
      Sets the listener that will obtain the results of the scanning.
      boolean shouldRotateScanningRegion()
      Returns true if scanning region should be rotated with device.

      • create

        @UiThread
public void create()
        This method must be called from activity's onCreate. If not called, recognition will not work.
        Overrides:
        create in class CameraViewGroup
        Throws:
        java.lang.UnsatisfiedLinkError - if native library could not be loaded
        java.lang.NullPointerException - if scan result listener or camera events listener is not set
        java.lang.IllegalStateException - if recognizer settings array is null or empty

      • setLifecycle

        public void setLifecycle​(@NonNull
                         androidx.lifecycle.Lifecycle lifecycle)
        Sets lifecycle that will be observed so that you don't have to manually call create(), resume() and other lifecycle methods.
        Parameters:
        lifecycle - lifecycle that will be observed

      • prepareCameraSettings

        protected final void prepareCameraSettings​(@NonNull
                                           com.microblink.documentverification.hardware.camera.CameraSettings settings)
        Description copied from class: BaseCameraView
        Called inside onCreate method before creating camera manager. Use this method to create camera settings that are used on each startPreview event.
        Overrides:
        prepareCameraSettings in class BaseCameraView

      • start

        @MainThread
public final void start()
        This method must be called from activity's onStart. If not called, recognition will not work.
        Overrides:
        start in class BaseCameraView

      • stop

        @MainThread
public final void stop()
        This method must be called from activity's onStop. If not called, recognition will not work.
        Overrides:
        stop in class BaseCameraView

      • resume

        @MainThread
public final void resume()
        This method must be called from activity's onResume. If not called, recognition will not work.
        Overrides:
        resume in class BaseCameraView

      • resumeScanning

        @AnyThread
public final void resumeScanning​(boolean resetState)
        This method resumes scanning loop that was paused by calling pauseScanning(). If resetState is 'true', resetRecognitionState() will be called. If resetState is 'false', recognition state will not be reset, so scanning after resume may use old scan data to boost quality.

        pauseScanning() and resumeScanning(boolean) are counting calls. This means that if you called pauseScanning() twice, you will also have to call resumeScanning(boolean) twice to actually resume scanning.

        Parameters:
        resetState - should internal state be reset when resuming scanning

      • pause

        @MainThread
public final void pause()

      • resetRecognitionState

        @AnyThread
public final void resetRecognitionState​(boolean hardReset)
        Resets the recognition state. If hard reset is requested, clears the cached data and all scanning results and recognition starts from the beginning.

        True if autofocus is required, otherwise false.

      • onActivityFlip

        protected void onActivityFlip()
        Description copied from class: BaseCameraView

      • setScanningRegion

        @UiThread
public final void setScanningRegion​(@Nullable
                                    Rectangle scanningRegion,
                                    boolean rotateRegionWithDevice)
        Define scanning region as a rectangle. Also define whether scanning region will rotate when device orientation changes.

        first parameter of rectangle is x-coordinate represented as percentage of view width, second parameter is y-coordinate represented as percentage of view height, third parameter is region width represented as percentage of view width and fourth parameter is region height represented as percentage of view height

        View width and height are defined in current context, i.e. they depend on screen orientation. If you allow your ROI view to be rotated, then in portrait view width will be smaller than height, whilst in landscape orientation width will be larger than height. This complies with view designer preview. If you choose not to rotate your ROI view, then your ROI view will be laid out either in portrait or landscape, depending on setting for your camera activity in AndroidManifest.xml

        Note that scanning region only reflects to native code - it does not have any impact on user interface. You are required to create a matching user interface that will visualize the same scanning region you set here.

        Parameters:
        scanningRegion - Rectangle to define a scanning region or null to scan entire image.
        rotateRegionWithDevice - If set to true, scanning region will be rotate when device changes orientation.

      • shouldRotateScanningRegion
