'Declaration

 

Public Function GetWordSpacesBefore( _

   ByVal OCRResultID As String, _

   ByVal WordIdx As Integer _

) As Integer

public int GetWordSpacesBefore( 

   string OCRResultID,

   int WordIdx

)

public function GetWordSpacesBefore( 

    OCRResultID: String;

    WordIdx: Integer

): Integer;

public function GetWordSpacesBefore( 

   OCRResultID : String,

   WordIdx : int

) : int;

public: int GetWordSpacesBefore( 

   string* OCRResultID,

   int WordIdx

)

public:

int GetWordSpacesBefore( 

   String^ OCRResultID,

   int WordIdx

)

Parameters

OCRResultID: The unique result identifier of the executed OCR process obtained by the RunOCR method.
WordIdx: The 0-based index of the word within the specified OCR result. It must be a value between 0 and GetWordCount(OCRResultID) - 1.

Return Value

The number of recognized spaces. Please always use the GetStat method to determine if this method has been successful.

It is recommend to use the GetStat method to identify the specific reason for the method's failure, if any.

How to find out the number of spaces before the recognized word within the OCR result.
