Detailed Description

OCR (Optical Character Recognition) Engine Observer.

This set of interfaces defines the observers of the OCR engine. This is the unique set for all types of engines. User needs to implement a concrete class which is derived from this class.

virtual void MOCREngineObserver::LayoutComplete	(	TInt	aError,
		const TOCRBlockInfo *	aBlocks,
		const TInt	aBlockCount
	)	`[pure virtual]`

This interface will be called after the Full Image Layout Analysis is completed.

This calling only valid when using the EEngineLayoutRecognize type of engine

Parameters:

	aError	Error code to indicate the completion status
	aBlocks	Pointer to the text information of the recognized image block, Please note that the memory ownership belongs to the OCR engine and will not be passed to your procedure after this calling
	aBlockCount	Number of block identified

Returns:: None

virtual void MOCREngineObserver::RecognizeBlockComplete	(	TInt	aError,
