| class CCamera::CCameraPreImageCaptureControl : public CBase |
CCameraPreImageCaptureControl class exposes an API for controlling image operations/settings prior to image capture.
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.
Client should not use old Capture methods present in class CCamera. Class CCameraImageCapture and class CCameraPostImageCaptureControl should be used rather.

Every MCaptureImageObserver::ImageBufferReady() will retrieve only one sub-frame. Full image will be reconstructed after receiving all the sub-frames.
The corresponding image capture call is considered to be complete only when every sub-frame has been received.
| void | EndEmbeddedStillCaptureSettingsL | ( | ) | [private] |
Marker method to mark end of providing selective settings for embedded still captures only (not to video capture)
Any feature setting issued after calling this method is treated as a normal setting operation.

Retrieves the supported spot combinations for the given focus mode.
Since maximum number of spots can go up to KMaxNumberOfFocusSpots, it can be easily known which spots are present in a particular array entry (every array entry is a bit field and every bit represents presence or absence of a particular spot). For example,if KMaxNumberOfFocusSpots is 32 and if a particular array entry is 0x07001000. This means that spot number 13,25,26 and 27 are being represented.
| CCamera::CCameraAdvancedSettings::TFocusMode aFocusMode | The focus mode for which the supported spot combinations have to be retrieved. |

The callback MPreImageCaptureControlObserver:: PrepareImageComplete() passes the ownership of the CCameraImageCapture* object to the client.
This needs to be called every time client wishes to change prepare image parameters or if the client wishes to create a new CCameraImageCapture* object.
Next PrepareImageCapture can be called only after receiving the notification KUidECamEventReadyForNextPrepare.
If drive mode is EDriveModeTimeNudgeCapture, when the client initiates image capture the total amount of images requested by the client (specified in TDriveModeDependentAttributes) will be returned to the client (via MCaptureImageObserver::ImageBufferReady()) or saved to file. No other instance of CCameraImageCapture can be created whilst using this drive mode until the first instance is destroyed.

| IMPORT_C void | SetDirectSavingTypeL | ( | TDirectSavingType | aDirectSavingType | ) |
Instructs the ECam implementation to use the desired type of direct saving option as specifed by its state.
Whether or not the direct saving option is used, client will receive the MCaptureImageObserver::ImageCaptureComplete() callback to mark the completion of the image capture operation.
If EDirectSavingNotUsed, direct saving will not be used. Images will be received in buffer MCameraImageBuffer through callback MCaptureImageObserver::ImageBufferReady().
If EDirectSavingHighResolutionFileOnly, direct saving to file option will be used. But no cut down version of the image will be saved to file. Callback to be used is MCaptureImageObserver::ImageDirectSavingCompleted().
If EDirectSavingWithLowerResolutionFile, apart from direct saving to file option for the actual image, a cut down version of the image will be saved to another specified file. Callbacks to be used are MCaptureImageObserver:: ImageDirectSavingCompleted() for actual image and MCaptureImageObserver::CutDownImageDirectSavingCompleted() for lower resolution image.
Clients need to provide the filename before capturing still images under direct saving option. Callback MCaptureImageObserver::ImageDirectSavingCompleted() may provide error KErrNotReady if filenames are not provided before images are captured for direct saving. Similarly, if cut down version of image is also to be saved to file, MCaptureImageObserver::CutDownImageDirectSavingCompleted() may provide error KErrNotReady if filenames are not provided before hand.
Direct saving to file will continue even if the client application gets closed for any reasons.

It is upto the implementation how many digits it uses for sequence number. Accordingly, padding will be done with zeroes.
