Method Detail

• 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)

  Used to add frame handler that will be called on each next frame

• removeFrameHandler

   abstract Unit removeFrameHandler(FrameHandler frameHandler)

  Unregisters FrameHandler.

  Parameters:

  frameHandler - handler to unregister.

• 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.

  <p> This is asynchronous process, so results are reported via {@link PictureCallback} added in {@link #addPictureCallback(PictureCallback)}. If snapping process is still going all subsequent calls to {@link #takePicture(boolean)} are ignored. <p> After picture is taken, camera preview is stopped. If you wish it continue, use {@link #startPreview()} <p> If view is paused, this call is ignored.

  Parameters:

  acquireFocus - {@code true} to perform auto-focus before shooting.

• addPictureCallback

   abstract Unit addPictureCallback(BasePictureCallback pictureCallback)

  Adds callback which will be notified when picture will be taken. Callbacks are invoked on a worker thread, so you can safely perform "heavy" operations here.

  Parameters:

  pictureCallback - callback to register.

• removePictureCallback

   abstract Unit removePictureCallback(BasePictureCallback pictureCallback)

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

  Parameters:

  pictureCallback - callback to unregister.

• setCameraOpenCallback

   abstract Unit setCameraOpenCallback(CameraOpenCallback cameraOpenCallback)

  Callback which will be invoked when camera will be opened

  Parameters:

  cameraOpenCallback - callback

• addCameraStateCallback

   abstract Unit addCameraStateCallback(CameraStateCallback cameraStateCallback)

  Adds callback which will be notified about camera state changes. Callbacks are invoked on a main thread.

  Parameters:

  cameraStateCallback - 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

• setOpticalZoomLevel

   abstract Unit setOpticalZoomLevel(Float zoomLevel)

  Sets current zoom by a linear zoom value ranging from 0f to 1.0f. Zoom Level 0f represents the minimum zoom while Zoom Level 1.0f represents the maximum zoom. Default value is 0f.

  Parameters:

  zoomLevel - Target zoom level

• setOpticalZoomRange

   abstract Unit setOpticalZoomRange(ZoomRange zoomRange)

  Set custom zoom range. Default value is ZoomRange(0f, 1f).

  Parameters:

  zoomRange - Target zoom range

• setCameraModule

   abstract Unit setCameraModule(CameraModule cameraModule)

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

  Parameters:

  cameraModule - CameraModule to use.

• 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.
