ImageProcessor::MImgProcessorObserver Class Reference

#include <imageprocessor/imageprocessorobserver.h>

class ImageProcessor::MImgProcessorObserver

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 )

voidImageProcessingComplete(CImgProcessor &aImageProcessor,
TIntaError
)[pure virtual]

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

Parameters
aImageProcessorThe CImgProcessor which has finished the rendering
aErrorany error happened in the CImgProcessor rendering process

ImageProcessorEvent ( CImgProcessor &, TInt, TUid, TInt )

voidImageProcessorEvent(CImgProcessor &aImageProcessor,
TIntaEventId,
TUidaUid,
TIntaId
)[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.

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

ImageProcessorInitializingComplete ( CImgProcessor &, TInt )

voidImageProcessorInitializingComplete(CImgProcessor &aImageProcessor,
TIntaError
)[pure virtual]

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

Parameters
aImageProcessorThe CImgProcessor which has finished the initialization
aErrorany error happened in the CImgProcessor initialize process

ImageProcessorPreviewInitializingComplete ( CImgProcessor &, TInt, TInt )

voidImageProcessorPreviewInitializingComplete(CImgProcessor &aImageProcessor,
TIntaPreviewId,
TIntaError
)[pure virtual]

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

Parameters
aImageProcessorThe CImgProcessor which has finished the initialization of its prview
aPreviewIdthe id of the preview which has finished the initialization
aErrorany error happened in the CImgProcessor preview initialize process

ImageProcessorPreviewRenderingComplete ( CImgProcessor &, TInt, TInt )

voidImageProcessorPreviewRenderingComplete(CImgProcessor &aImageProcessor,
TIntaPreviewId,
TIntaError
)[pure virtual]

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

Parameters
aImageProcessorThe CImgProcessor which has finished the rendering of its prview
aPreviewIdthe id of the preview which has finished the rendering
aErrorany error happened in the CImgProcessor preview rendering process
