setCropRectanglePixels

()

method

public function setCropRectanglePixels(_x:Number, _y:Number, _w:Number, _h:Number):void

Allows you to define a rectangle for cropping the frame. iOS only. Android implementation to come. E-mails us at support [at] diadraw.com with requests to move it up our TODO list.

Parameters

	`_x:Number` — Crop rectangle left coordinate in pixels.

	`_y:Number` — Crop rectangle top coordinate in pixels.

	`_w:Number` — Crop rectangle width in pixels.

	`_h:Number` — Crop rectangle height in pixels.

setExposureMode

()

method

public function setExposureMode(_mode:Number, _pointOfInterest:Point = null):void

Sets the exposure mode. iOS only. Android implementation to come. E-mails us at support [at] diadraw.com with requests to move it up our TODO list.

Parameters

	`_mode:Number` — Use one of the CameraSettings.ExposureModeconstants

	`_pointOfInterest:Point` (default = `null`) — Optional point of interest, which is supported on some devices. (0, 0) corresponds to the top left and (1, 1) - to the bottom right of the picture area with the home button on the right - applies even if the device is in portrait mode.

setFocusMode

()

method

public function setFocusMode(_mode:Number, _pointOfInterest:Point = null):void

Sets the focus mode. iOS only. Android implementation to come. E-mails us at support [at] diadraw.com with requests to move it up our TODO list.

Parameters

	`_mode:Number` — Use one of the CameraSettings.FocusModeconstants

	`_pointOfInterest:Point` (default = `null`) — Optional point of interest, which is supported on some devices. (0, 0) corresponds to the top left and (1, 1) - to the bottom right of the picture area with the home button on the right - applies even if the device is in portrait mode.

setPointOfInterest

()

method

public function setPointOfInterest(_pointCoordinates:Point, _displaySize:Point, _stage:Stage):void

Determines a particular point of interest for which to adjust focus, exposure and white balance. Use this to allow the user to select a point by tapping on the display. iOS only. Android implementation to come. E-mails us at support [at] diadraw.com with requests to move it up our TODO list.

Parameters

	`_pointCoordinates:Point` — The coordinates of the point of interest in the image's coordinate system.

	`_displaySize:Point` — The size of the image preview.

	`_stage:Stage` — A reference to the stage.

setRotationAngle

()

method

public function setRotationAngle(_angleDegrees:Number):void

Allows you to rotate the frame by an arbitrary angle, measured in degrees. You can use this to allow finger gestures to rotate the preview. iOS only. Android implementation to come. E-mails us at support [at] diadraw.com with requests to move it up our TODO list.

Parameters

_angleDegrees:Number — The rotation angle in degrees

setTorchMode

()

method

public function setTorchMode(_mode:Number):void

Sets the torch mode, if the device has a torch. iOS only. Android implementation to come. E-mails us at support [at] diadraw.com with requests to move it up our TODO list.

Parameters

_mode:Number — Use one of the NativeCameraExtension.TorchModeconstants

setTranslationPoint

Parameters

	`_offsetX:Number` — Horizontal translation offset in pixels

	`_offsetY:Number` — Vertical translation offset in pixels

setWhiteBalanceMode

()

method

public function setWhiteBalanceMode(_mode:Number):void

Sets the white balance mode. iOS only. Android implementation to come. E-mails us at support [at] diadraw.com with requests to move it up our TODO list.

Parameters

_mode:Number — Use one of the CameraSettings.WhiteBalanceModeconstants

method

public function startCameraPreview(_stage:Stage, _settings:CameraSettings = null):Boolean

Starts the video stream and dispatches NativeCameraDriverEvent.CAMERA_STARTED is dispatched if the camera has started successfully. NativeCameraDriverEvent.FRAME_READY is dispatched, when a frame from the camera is ready to be read; you can obtain the data by reading the event's bitmapData property.

Parameters

	`_stage:Stage` — A reference to the stage.

	`_settings:CameraSettings` (default = `null`) — The settings with which the camera should be run.

Returns

Boolean — true if the settings were accepted, false otherwise. If false is returned, the native code sends a StatusEvent with a message, describing what the problem was: unsupported preset, front camera not supported, etc.
