virtual void MOCREngineRecognizeBlock::RecognizeBlockL ( const TInt aBitmapHandle , const TOCRLayoutBlockInfo aLayoutInfo ) [pure virtual]
This method recognizes text in a single block.
Parameters:
aBitmapHandle Handle of the image(get from CFbsBitmap::Handle()) aLayoutInfo Block information
Returns: None Leave: KErrNotSupported Image shall be in BMP format (24bit colored or 8 bit grayscale) and the size shall not exceed 1600x1200 in pixel Leave: KErrNotReady Internal object is not constructed Leave: KErrAbort Child thread does not exist or operation is aborted Leave: KErrCouldNotConnect No connection to the font and bitmap server could be made Leave: KErrUnknown No bitmap could be found with the specified handle number Leave: KErrArgument aRegionInfo is available Leave: KErrServerBusy OCR service is busy
virtual void MOCREngineRecognizeBlock::RecognizeSpecialRegionL ( const TInt aBitmapHandle , const TRegionInfo aRegionInfo ) [pure virtual]
This method recognizes text with special content in a single block.
Note that SetActiveLanguageL has to be called first and language must be set to TLanguage::ELangEnglish
Parameters:
aBitmapHandle Handle of the image(get from CFbsBitmap::Handle()) aRegionInfo Block information
