IMPORT_C ~CImageMaskProcessorReadCodec();

Description

Destructor.

protected: IMPORT_C CImageMaskProcessorReadCodec();

Description

Default constructor.

protected: IMPORT_C void ConstructL();

Description

Second phase constructor.

protected: IMPORT_C CImageProcessor* MaskProcessor() const;

Description

Returns a pointer to the codec's CImageProcessor used when decoding the image mask.

Return value

CImageProcessor * A pointer to the codec's CImageProcessor derived object.

protected: IMPORT_C void SetMaskProcessor(CImageProcessor *aMaskProc);

Description

Replaces a codec's existing CImageProcessor with a new fully constructed instance of the same object.

Ownership of the new instance is transferred.

Parameters

CImageProcessor *aMaskProc A pointer to a full constructed CImageProcessor derived object.
