Constructor Detail

CameraControllerApi2

public CameraControllerApi2(android.content.Context context)

Instantiate the CameraControllerApi2 object.

Parameters:

context - Context.

Method Detail

setCameraDevice

public void setCameraDevice(android.hardware.camera2.CameraDevice cameraDevice)

Set the camera device with the new camera API

Parameters:

cameraDevice - CameraDevice.

setCameraId

public void setCameraId(int cameraId)

Set the camera id

Specified by:

setCameraId in class CameraController

Parameters:

cameraId - The camera id, integer.

setReadyToDecodeListener

public void setReadyToDecodeListener(OnImageReadyToBeSent listener)

Parameters:

listener - OnImageReadyToBeSent.

getCameraResolution

public android.graphics.Point getCameraResolution()

Get the actual resolution given from the camera

Specified by:

getCameraResolution in class CameraController

Returns:

Point(x,y)

configureTransform

public void configureTransform(int viewWidth,
                               int viewHeight)

Configures the necessary Matrix transformation to `mTextureView`. This method should be called after the camera preview size is determined in setUpCameraOutputs and also the size of `mTextureView` is fixed.

Parameters:

viewWidth - The width of `mTextureView`

viewHeight - The height of `mTextureView`

createCameraPreviewSession

public void createCameraPreviewSession()

Creates a new CameraCaptureSession for camera preview.

getPreviewOrientation

public int getPreviewOrientation()

Finds the angle to apply to the preview frames to get an image with natural orientation. Preview frames are delivered raw, as a byte array, according to the camera sensor physical orientation. Based on device orientation, camera (both given at class instantiation) and camera sensor orientation.

Specified by:

getPreviewOrientation in class CameraController

Returns:

int angle to apply to preview frames

message - The what field of the message to be sent.

isZoomAvailable

public boolean isZoomAvailable()

Get the information about the availability of the zoom .

Specified by:

isZoomAvailable in class CameraController

Returns:

boolean

public void setZoomCamera(int zoom)

Set the zoom of the camera.

Specified by:

setZoomCamera in class CameraController

Parameters:

zoom - Level of the zoom to set for the camera.

manualFocus

public void manualFocus(float motionX,
                        float motionY,
                        android.view.View view,
                        boolean isFocusRectangleVisible)

On double tap we switch to manual focus. We try focusing on the region were the double tap was done.

Specified by:
