Row Settings, Row Recognition, and Obtaining Recognition Results

// Row settings
		int msetline(OCRRect* pocrrect,unsigned char alinedirection);
		Input
		OCRRect*		pocrrect;		Row rectangle
		unsigned char	alinedirection;	Row direction
					HORIZONTAL_LINE.....Vertical writing
					VERTICAL_LINE.......Horizontal writing
		Return value
		0.................Normal termination
		MEMORY_SHORTAGE...Insufficient memory
        -1................An error has occurred in the target image for recognition (post-processing is possible)
		-2................The target image for recognition is too small or the tilt of the character string is too large (post-processing is not possible)
// Use mserlineuser if pocrrect is not an enclosing rectangle but contains spaces
		int msetlineuser(OCRRect* pocrrect,unsigned char alinedirection);
		Input
		OCRRect*		pocrrect;		Row rectangle
		unsigned char	alinedirection;	Row direction
					HORIZONTAL_LINE.....Vertical writing
					VERTICAL_LINE.......Horizontal writing
		Return value
		0.................Normal termination
		MEMORY_SHORTAGE...Insufficient memory
        -1................An error has occurred in the target image for recognition (post-processing is possible)
		-2................The target image for recognition is too small or the tilt of the character string is too large (post-processing is not possible)
// Row recognition
		int mrecognize(unsigned long afilter);
		Input
		unsigned long afilter;			Character type filter
			Characters other than those specified by afilter will not be included in the result
			Recognition accuracy and speed will also increase
		Return value
		0.................Normal termination
		MEMORY_SHORTAGE...Insufficient memory
// Obtaining recognition results
		int mgetresult(int& resultnum,OCRResult* pocrresult);
		Input
		int&		resultnum;		Size of OCRResult structure array
		OCRResult*	pocrresult;		OCRResult structure array
		Output
		int&		resultnum;		Number of elements in the result array
		OCRResult*	pocrresult;		OCRResult structure array
		Return value
		0...................Normal termination
		 BUFFER_OVERFLOW.....Buffer overflow
		  In this case, the actual result is not included,
		  but the number of elements required for the structure array is returned to resultnum
		※:Setting pocrresult as NULL and calling will set the number of recognition results to resultnum. 
		   When you only want to obtain the number of recognition results, set NULL as the second argument and call.
