Method Detail

animateQuadToDefaultPosition

@AnyThread
public void animateQuadToDefaultPosition()

Call this method to begin quadrilateral animation to its default position. It is safe to call this method from non-UI thread.

setDetectionRelativeDestination

public void setDetectionRelativeDestination(@Nullable
                                            android.graphics.RectF detectionRelativeDestination)

Sets position of the destination view in which the detection will be shown, relative to processed frame. View position is required for performing further transformation of detection coordinates in order to display detection correctly on the destination view.

Parameters:

detectionRelativeDestination - position of the destination view where detection will be shown, relative to processed frame. Set to null if no further transformation is needed in cases when destination view matches the processed part of the recognized frame.

animateQuadToDetectionPosition

@AnyThread
public void animateQuadToDetectionPosition(@NonNull
                                           DisplayableQuadDetection quadDetection)

Call this method to begin quadrilateral animation to detected quadrilateral.

Parameters:

quadDetection - detection to which quad will be animated

setAnimationDuration

public void setAnimationDuration(long durationMs)

Sets the duration in miliseconds of quadview animation.

Parameters:

durationMs - duration in miliseconds of quadview animations.

configurationChanged

@MainThread
public void configurationChanged(@NonNull
                                 RecognizerRunnerView recognizerRunnerView,
                                 @NonNull
                                 android.content.res.Configuration newConfig)

Inform quadview of configuration change event.

Parameters:

recognizerRunnerView - RecognizerRunnerView used to create the QuadView. Make sure you've called changeConfiguration on it before calling this method.

newConfig - New configuration as given by onConfigurationChanged activity callback.

isAnimationInProgress

public boolean isAnimationInProgress()

Returns true if quad view animation is currently in progress.

Returns:

true if quad view animation is currently in progress.

setAnimationListener

public void setAnimationListener(@Nullable
                                 QuadViewAnimationListener listener)

Sets a listener that will be notified when quad animation has started and finished.

setInitialHostActivityOrientation

public void setInitialHostActivityOrientation(int hostActivityOrientation)

Changes initial host activity orientation.

Parameters:

hostActivityOrientation - allowed values are:
ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE
ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT
