Detailed Description

Plugin API for the observer of CImgProcessor. When the CImgProcessor is set to EOptionNone, which means effects, geometric operations and rendering are applied asynchronously. After certain operations such as initialization or rendering finished, or after each iteration of operation, the certain function will be called, so that user can perform corresponding response.

Member Function Documentation

ImageProcessingComplete ( CImgProcessor &, TInt )

void	ImageProcessingComplete	(	CImgProcessor &	aImageProcessor,
			TInt	aError
		)	[pure virtual]

The derived class must provide an implementation to perform actions after ImageProcessor complete its action of image processing

Parameter	Description
aImageProcessor	The CImgProcessor which has finished the rendering
aError	any error happened in the CImgProcessor rendering process

ImageProcessorEvent ( CImgProcessor &, TInt, TUid, TInt )

void	ImageProcessorEvent	(	CImgProcessor &	aImageProcessor,
			TInt	aEventId,
			TUid	aUid,
			TInt	aId
		)	[pure virtual]

During image processing, after each iteration, this function will be notified and the derived class must provide an implementation to perform actions (optional) such as showing messages to response.

Parameter	Description
aImageProcessor	The current CImgProcessor
aEventId	the event id of the current iteration, which is defined in imageprocessor.h as TEvent enumeration, could be EEventInitializing, EEventProcessing, EEventRendering, EEventPreviewInitializing or EEventPreviewRendering,
aUid	The value depends on aEventId, and reserved for future purpose
aId	The value depends on aEventId, for example, if aEventId is EEventPreviewRendering, aId will be the id of the preview.

ImageProcessorInitializingComplete ( CImgProcessor &, TInt )

void	ImageProcessorInitializingComplete	(	CImgProcessor &	aImageProcessor,
			TInt	aError
		)	[pure virtual]

The derived class must provide an implementation to perform actions after ImageProcessor complete its initialization

Parameter	Description
aImageProcessor	The CImgProcessor which has finished the initialization
aError	any error happened in the CImgProcessor initialize process

ImageProcessorPreviewInitializingComplete ( CImgProcessor &, TInt, TInt )

void	ImageProcessorPreviewInitializingComplete	(	CImgProcessor &	aImageProcessor,
			TInt	aPreviewId,
			TInt	aError
		)	[pure virtual]

The derived class must provide an implementation to perform actions after the preview of ImageProcessor complete its initialization

Parameter	Description
aImageProcessor	The CImgProcessor which has finished the initialization of its prview
aPreviewId	the id of the preview which has finished the initialization
aError	any error happened in the CImgProcessor preview initialize process

ImageProcessorPreviewRenderingComplete ( CImgProcessor &, TInt, TInt )

void	ImageProcessorPreviewRenderingComplete	(	CImgProcessor &	aImageProcessor,
			TInt	aPreviewId,
			TInt	aError
		)	[pure virtual]

The derived class must provide an implementation to perform actions after the preview of ImageProcessor complete its rendering process

Parameter	Description
aImageProcessor	The CImgProcessor which has finished the rendering of its prview
aPreviewId	the id of the preview which has finished the rendering
aError	any error happened in the CImgProcessor preview rendering process
