/** 

This class is used to perform image processing operations on the camera.

These include brightness, contrast, gamma, hue, sharpness and saturation adjustments. The client is also 

able to perform simple image transformations like cropping, rotation, mirroring, scaling, noise reduction and glare reduction. .  

When an operation selection is complete, all clients are notified with the respective event UID.

As often cameras may support only a subset of discrete values of the allowed range, 

the API allows the client to retrieve those and use them explicitly.   

@note This class is not intended for sub-classing and used to standardise existing

	  varieties of implementations.

@note it is assumed that setting a new value for a transformations(transform, adjust, effect) effectively

	  activates the transformations. Whilst for effects and adjustments there is always a value, transforms 

	  may have a dependency on other parameters and 

	  crop 	- requires setting of source rectangle.

	  scale - will use setting of source rectangle, and the magnification factor is 

	  		  determined by the source rectangle and the output size. This is always magnification.

	  		  if a value is set, it is assumed to be a scaling factor multiplied by KECamFineResolutionFactor

	  		  and set to integer.

	  mirror - values of TMirror type.

	  rotation - the angle in degrees.

	  noise reduction - TNoiseReduction.

	  glare removal - TGlareReduction.

	  	Example 

		@code

		// Lets assume that an application would need to check whether gamma correction is 

		// supported on a particular platform. After obtaining a valid pointer to the interface, 

		// it would call GetSupportedTransformationsL() to obtain the list of the supported 

		// transformations and check whether KUidECamEventImageProcessingAdjustGamma

		// is in the list. If it is then call SetTranformationValue(KUidECamEventImageProcessingAdjustGamma, 200);

		// to set the new value. A notification will be generated to the client to indicate success.

		RArray<TUid> suppTransforms; // array of supported transformations

		CleanupClosePushL(suppTransforms);

		imageProcess->GetSupportedTransformationsL(suppTransfUids);

		 ...

		// if the gamma is supported 

		TInt gammaCorrection = 200; // gamma correction of 2.0

		imageProcess->SetTranformationValue(KUidECamEventImageProcessingAdjustGamma, gammaCorrection);

		...

		// pop stack to close the RArray

		@endcode

@note   If the class methods leave, the output type parameter value is not guaranteed to be valid.
