• getAttachedFrameHandler

   abstract <T extends FrameHandler> T getAttachedFrameHandler(Class<T> clazz)

  Check whether there is same class of FrameHandler attached to the view return object of the same class if exists otherwise null

• addFrameHandler

   abstract Unit addFrameHandler(FrameHandler frameHandler)

• setPreviewMode

   abstract Unit setPreviewMode(CameraPreviewMode mode)

  Set the camera preview mode. By default - CameraPreviewMode.FILL_IN.

  Parameters:

  mode -

  • camera preview mode

• takePicture

   abstract Unit takePicture(Boolean acquireFocus)

  Takes picture.

  This is asynchronous process, so results are reported via PictureCallback added in addPictureCallback. If snapping process is still going all subsequent calls to takePicture are ignored.

  After picture is taken, camera preview is stopped. If you wish it continue, use startPreview If view is paused, this call is ignored.

  Parameters:

  acquireFocus - true to perform auto-focus before shooting.

• takePicture

   abstract Unit takePicture(Boolean acquireFocus, Boolean isCapturedAutomatically)

  Takes picture.

  This is asynchronous process, so results are reported via PictureCallback added in addPictureCallback. If snapping process is still going all subsequent calls to takePicture are ignored.

  After picture is taken, camera preview is stopped. If you wish it continue, use startPreview If view is paused, this call is ignored.

  Parameters:

  acquireFocus - true to perform auto-focus before shooting.

  isCapturedAutomatically - allows to define if the picture was taken automatically by any of AutoSnappingController.

• addPictureCallback

   abstract Unit addPictureCallback(BasePictureCallback pictureCallback)

• setCaptureCallback

   abstract Unit setCaptureCallback(CaptureCallback captureCallback)

  Sets the callback which will be notified about the moment of actual image capture.

  Parameters:

  captureCallback - callback to register

• removeCameraStateCallback

   abstract Unit removeCameraStateCallback(CameraStateCallback cameraStateCallback)

  Removes callback, so it won't receive any further notifications.

  Parameters:

  cameraStateCallback - callback to unregister.

• addTakePictureCallback

   abstract Unit addTakePictureCallback(CameraTakePictureCallback cameraTakePictureCallback)

  Adds callback which will be notified about take picture operation process. Callbacks are invoked on a main thread.

  Parameters:

  cameraTakePictureCallback - callback to register.

• removeTakePictureCallback

   abstract Unit removeTakePictureCallback(CameraTakePictureCallback cameraTakePictureCallback)

  Removes callback, so it won't receive any further notifications.

  Parameters:

  cameraTakePictureCallback - callback to unregister.

• setAutoFocusOnTouch

   abstract Unit setAutoFocusOnTouch(Boolean autoFocusOnTouch)

  Parameters:

  autoFocusOnTouch - if true - auto focus on touch will be enabled, false - otherwise.

• autoFocus

   abstract Unit autoFocus()

  Performs auto-focus.

  If there is no auto-focus capabilities on this device, does nothing.

  If view is paused, this call is ignored.

• continuousFocus

   abstract Unit continuousFocus()

  Cancels auto-focus and performs continuous-focus. Should be executed from the main thread and when camera is opened

  If there is no continuous-focus capabilities on this device, does auto-focus.

  If view is paused, this call is ignored.

• useFlash

   abstract Unit useFlash(Boolean useFlash)

  Enables or disables camera flash.

  If there is no flash on this device, does nothing.

  If view is paused, this call is ignored.

  Parameters:

  useFlash - true to enable flash.

• lockToPortrait

   abstract Unit lockToPortrait(Boolean lockPicture)

  Locks camera in portrait mode

  Parameters:

  lockPicture - if true - taken picture will ba locked to the portrait orientation, false - picture orientation depends on the device sensor.

• lockToLandscape

   abstract Unit lockToLandscape(Boolean lockPicture)

  Locks camera in landscape mode

  Parameters:

  lockPicture - if true - taken picture will ba locked to the landscape orientation, false - picture orientation depends on the device sensor.

• unlockOrientation

   abstract Unit unlockOrientation()

  Unlocks camera orientation

• usePinchToZoom

   abstract Unit usePinchToZoom(Boolean usePinchToZoom)

  Enables/disables Pinch-to-Zoom camera functionality

  Parameters:

  usePinchToZoom - true if Pinch-to-Zoom should be enabled, false - otherwise

• setPhysicalZoomRange

   abstract Unit setPhysicalZoomRange(ZoomRange zoomRange)

  Set custom zoom range. Default value is ZoomRange(0.5f, 100f).

  Parameters:

  zoomRange - Target zoom range

• setPhysicalZoom

   abstract Unit setPhysicalZoom(Float zoomLevel)

  Allows to set camera physical zoom value, if the value out of range of real camera min and max values it chooses min or max value. Example: camera physical zoom range 1f..5f if we set 6f it will set 5f. Default value is 1f.

  Parameters:

  zoomLevel - Target zoom level

• setCameraModule

   abstract Unit setCameraModule(CameraModule cameraModule)

  Defines a camera module. By default is CameraModule.BACK.

  Parameters:

  cameraModule - CameraModule to use.

• isFlashEnabled

   abstract Boolean isFlashEnabled()

  Returns the current state of the flashlight Should be executed from the main thread and when camera is opened

• setShutterSound

   abstract Unit setShutterSound(Boolean value)

  Set camera shutter sound state. true if system sound should be played on the take picture event, false - otherwise. By default, the camera plays the system-defined camera shutter sound when takePicture() is called.

  Note that devices may not always allow disabling the camera shutter sound. If the shutter sound state cannot be set to the desired value, this method will be ignored.

• startPreview

   abstract Unit startPreview()

  Starts/resumes camera preview stream. Usually used after picture was taken.

• stopPreview

   abstract Unit stopPreview()

  Stops camera preview stream.

• restartPreview

   abstract Unit restartPreview()

  Restarts preview stream.

• lockMinFocusDistance

   abstract Unit lockMinFocusDistance(Boolean lock)

  Locks the min supported focus distance and disables continuous focus

  Parameters:

  lock - if true minimal available focus distance will be locked, false - otherwise Default is false.

• setForceMaxSnappingSize

   abstract Unit setForceMaxSnappingSize(Boolean enabled)

  Set whether camera should force maximum possible size of snapped picture or use maximum size that available with the same aspect ratio as preview by default set to false This parameter works only with ScanbotCameraXView enabled

• setForceMaxSnappingQuality

   abstract Unit setForceMaxSnappingQuality(Boolean enabled)

  Set whether camera should force maximum possible quality of snapped picture. As a result snapping speed could be significantly slower and result image could be bigger. By default set to false This parameter works only with ScanbotCameraXView enabled

• setSnappingAutoAdjustment

   abstract Unit setSnappingAutoAdjustment(Boolean enabled)

  Set whether camera should automatically adjusts the final image with the surrounding scenery. For example, the vendor library implementation might do low-light detection and switch to low-light mode or HDR to take the picture. Alternatively, the face retouch mode could be automatically applied when taking a portrait image. This delegates modes to the vendor library implementation to decide.

• getDelayAfterFocusCompleteMs

   abstract Long getDelayAfterFocusCompleteMs()

  Delay that camera will took before snap on auto focus complete called from camera core in ms. For some devices this callback could call even before real auto focus completed, so we need to take some delay before snapping. Usually you can set 500ms. By default it is set to 20ms.

• setDelayAfterFocusCompleteMs

   abstract Unit setDelayAfterFocusCompleteMs(Long delayAfterFocusCompleteMs)

  Delay that camera will took before snap on auto focus complete called from camera core in ms. For some devices this callback could call even before real auto focus completed, so we need to take some delay before snapping. Usually you can set 500ms. By default it is set to 20ms.
