| class CCamera::CCameraAdvancedSettings : public CBase |
CCamera advanced settings class exposes an API for controlling individually digital camera advanced settings. These settings directly relate to the image acquisition phase both for still images and video.
This class is not intended for sub-classing and used to standardise existing varieties of implementations.
If the class methods leave, the output type parameter value is not guaranteed to be valid.

| IMPORT_C | CCameraAdvancedSettings | ( | CCamera & | aOwner | ) | [private] |
CCameraAdvancedSettings Constructor.
| CCamera & aOwner | a reference to a CCamera object providing the settings. |
| IMPORT_C TInt | Aperture | ( | ) | const |
Get current aperture value. The default aperture value is ECAM implementation specific and could be either auto aperture or any other supported value.
| IMPORT_C TBool | ApertureExposureLockOn | ( | ) | const |
Gets the current state for aperture and exposure lock.
| IMPORT_C TAutoFocusArea | AutoFocusArea | ( | ) | const |
Gets current chosen auto focus area on the camera.

| IMPORT_C TBool | AutomaticSizeSelectionChangeOn | ( | ) | const |
Retrieves the state for automatic size selection option. Default value is EFalse.
| IMPORT_C TInt | BurstImages | ( | ) | const |
: due to memory or image size limitations the actual number may be less.
| IMPORT_C TInt | CameraIndex | ( | ) | const |
Gets current camera index. The index uniquely identifies the camera on the device.
| IMPORT_C TCameraType | CameraType | ( | TInt | aCameraIndex | ) |
Get the type of a specific camera denoted by its index. A pluggable camera may not necessarily be physically present. The type denotes whether the slot allocated to that index is for pluggable or onboard camera. TCameraType
| TInt aCameraIndex | An integer in the range of [0: CCamera::CamerasAvailable()-1]. |
| IMPORT_C void | ConstructL | ( | ) | [private] |
CCameraAdvancedSettings second phase constructor.
Function used to initialise internal state of the object. Uses reference to the camera to retrieve Camera advanced settings interface pointer.
| IMPORT_C TInt | ContinuousAutoFocusTimeout | ( | ) | const |
Gets the current value for continuous autofocus timeout. Timeouts are in microseconds.
| IMPORT_C void | CreateContinuousZoomL | ( | MContinuousZoomObserver & | aObserver, |
| TContinuousZoomType | aContinuousZoomType, | |||
| CCameraContinuousZoom *& | aContinuousZoom | |||
| ) | ||||
Creates an instance of a CCameraContinuousZoom object and returns it to the client. Ownership of the object is passed to the client.
Client must not delete the continuous zoom object if CCameraContinuousZoom::StartContinuousZoomL() has been called as MContinuousZoomObserver callbacks are still expected by the implementation. Clients should therefore only delete the object once the MContinuousZoomObserver::ContinuousZoomCompleted() callback has been received or has explicitly stopped the continuous zoom via StopContinuousZoom().
| MContinuousZoomObserver & aObserver | Reference to a continuous zoom observer which will be used to issue callbacks to the client. |
| TContinuousZoomType aContinuousZoomType | The continuous zoom type with which the continuous zoom object will be initialised. |

| void | DisableCameraStateSavingL | ( | RWriteStream & | aCustomCameraState | ) | [private] |
Instructs the implementation to stop saving the custom state in the RWriteStream& as given by SaveCameraStateL(RWriteStream& aCustomCameraState).
| RWriteStream & aCustomCameraState |
| void | DisableStateSavingL | ( | ) | [private] |
Instructs the implementation to stop saving the current state in the RWriteStream& as given by EnableStateSavingL(RWriteStream& aLatestCameraState).
| void | EnableStateSavingL | ( | RWriteStream & | aLatestCameraState | ) | [private] |
Instructs the implementation to continuously save the current state before releasing the camera or being overtaken.
The RWriteStream gives the implementation the facility to seek and overwrite any incorrectly updated state (in the event of power failure, for example). Given stream sink shall support repositioning.
The ECam client should be careful not to use the saved state for a particular camera in order to restore a different camera later on. Though the implementation will be expected to take care of such things since the content of the files are only meaningful for the implementation.
The RWriteStream reference is not valid across the process.
| RWriteStream & aLatestCameraState | A RWriteStream reference which will be used by the implementation to continuously save the latest camera state. |

| TPerformanceLevel & | aLowMemoryConsumptionLevel, | |||
| TPerformanceLevel & | aLowPowerConsumptionLevel | |||
| ) | const | |||

| IMPORT_C TInt | ExposureCompensation | ( | ) | const |
Use TInt GetExposureCompensation(TInt& aExposureCompensation);
Get the current exposure compensation steps. Positive values increase exposure times, negative reduce exposure times. The change is not cumulative i.e. the change is stateless. Each call assumes no previous compensation has been performed i.e. that there is a zero compensation.
if returned value is 2 (compensation steps) and the current exposure compensation step is 0.3 EV, then the actual compensation effect will be 0.6 EV.
| IMPORT_C TInt | ExposureCompensationStep | ( | ) | const |

Gets current focus mode on the camera. The result is a valid TFocusMode value.
| IMPORT_C TFocusRange | FocusRange | ( | ) | const |
Gets current focus range on the camera.
if CCamera::New2L() or CCamera::NewDuplicate2L() is not used to create CCamera object, it is assumed that application is not prepared to receive extra added enum values. So, any extra enum value received from the implementation will be dropped and EFocusRangeAuto would be passed instead. To receive extra added enum values, application should rather use CCamera::New2L() or CCamera::NewDuplicate2L() to create camera object. In this case, application is assumed to be prepared to receive unrecognised enum values

if CCamera::New2L() or CCamera::NewDuplicate2L() is not used to create CCamera object, it is assumed that application is not prepared to receive extra added uid values (new settings added). So, any extra uid value passed from the implementation will be filtered at this point. To receive extra added uid values, application should rather use CCamera::New2L() or CCamera::NewDuplicate2L() to create camera object. In this case, application is assumed to be prepared to receive unrecognised uid values

| RArray< TInt > & aFStops | A reference to an empty array of TInt which would be populated by the implementation with the specific supported values. If the array is empty on return, the camera supports all integer values in the aperture range. Each value is multiplied by a factor of KECamFineResolutionFactor. |

Such approach allows for support for both linear and non-linear zoom steps. When camera device doesn't support this, empty array may be returned and TValueInfo may be ENotActive; corresponding getter/setters for this feature should not be used in such a case.
| RArray< TInt > & aDigitalZoomSteps | Array to hold digital zoom values multiplied by KECamFineResolutionFactor to retain precision. So that if zoom is not supported the array will return a single element of value KECamFineResolutionFactor. |

if CCamera::New2L() or CCamera::NewDuplicate2L() is not used to create CCamera object, it is assumed that application is not prepared to receive extra added uid values (new settings added). So, any extra uid value passed from the implementation will be filtered at this point. To receive extra added uid values, application should rather use CCamera::New2L() or CCamera::NewDuplicate2L() to create camera object. In this case, application is assumed to be prepared to receive unrecognised uid values
| IMPORT_C TInt | GetExposureCompensation | ( | TInt & | aExposureCompensation | ) | const |
Get the current exposure compensation steps. Positive values increase exposure times, negative reduce exposure times. The change is not cumulative i.e. the change is stateless. Each call assumes no previous compensation has been performed i.e. that there is a zero compensation.

| TValueInfo & | aInfo | |||
| ) | const | |||
Get exposure compensation steps as integers multiplied by KECamFineResolutionFactor. For example 0.3 EV is 30.
When camera device doesn't support this, empty array may be returned and TValueInfo may be ENotActive; corresponding getter/setters for this feature should not be used in such a case. When camera device is incapable of revealing the exposure compensation steps supported, it has to be assumed that camera will work only on the permanently set value. If this value is not known, empty array may be returned and TValueInfo may be ENotActive; corresponding getter/setters for this feature should not be used in such a case.

if retrieved value is 2 (compensation steps) and the current flash compensation step is 0.3 EV, then the actual compensation effect will be 0.6 EV.
Use this method in place of deprecated TInt FlashCompensation()
| TInt & aFlashCompensation | Reference to the current number of compensation steps as an integer. |
| IMPORT_C void | GetFlashCompensationRangeInSteps | ( | TInt & | aNegativeCompensation, |
| TInt & | aPositiveCompensation | |||
| ) | const | |||
This range may change if a different compensation step is selected. For example if flash compensation range is in the range -1EV 1.5EV and the selected flash compensation step is selected to be 0.3 EV, the result of this call will be aNegativeCompensation = -3 and aPositiveCompensation = 5. as there can be only three full steps for negative compensation (1/0.3) and five for flash power boost (1.5/0.3). In this way developers, having pre-selected a step value from the supported set, would need to provide just the multiplier (in steps) and the direction (the sign). Steps are always assumed integers.
| IMPORT_C TInt | GetFlashCompensationStep | ( | TInt & | aFlashCompensationStep | ) | const |
Get current flash power compensation step.
Use this method in place of deprecated TInt FlashCompensationStep()

When camera device is incapable of revealing the flash compensation steps supported, it has to be assumed that camera will work only on the parmanently set value. If this value is not known, empty array may be returned and TValueInfo may be ENotActive; corresponding getter/setters for this feature should not be used in such a case.

| TISORateType & aISORateType | A reference to the type of ISO rate set. EISONone means feature is not supported. |
| TInt & aParam | Depending on the value of aISORateType, possible values of aParam are one of the following:- A reference to the redundant parameter in case of manual type of ISO rate(EISOManual) OR A reference to the redundant parameter in case of unprioritised type of auto ISO(EISOAutoUnPrioritised) OR A reference to the highest ISO rate that may be picked up in case of ISO prioritised type of auto ISO(EISOAutoISOPrioritised) OR A reference to the slowest shutter speed that may be picked up in case of shutter speed prioritised type of auto ISO(EISOAutoShutterSpeedPrioritised) OR A reference to the minimum aperture opening that may be picked up in case of aperture prioritised type of auto ISO(EISOAutoAperturePrioritised) |
