GetWordCharacterCount Method (GdPictureSegmenter)

In This Topic
Returns the number of characters within the specified word, that is a part of the segmentation result specified by its index.
Syntax
'Declaration
 
Public Function GetWordCharacterCount( _
   ByVal SegmentationResultID As String, _
   ByVal WordIdx As Integer _
) As Integer
public int GetWordCharacterCount( 
   string SegmentationResultID,
   int WordIdx
)
public function GetWordCharacterCount( 
    SegmentationResultID: String;
    WordIdx: Integer
): Integer; 
public function GetWordCharacterCount( 
   SegmentationResultID : String,
   WordIdx : int
) : int;
public: int GetWordCharacterCount( 
   string* SegmentationResultID,
   int WordIdx
) 
public:
int GetWordCharacterCount( 
   String^ SegmentationResultID,
   int WordIdx
) 

Parameters

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

Return Value

The number of characters. Please always use the GetStat method to determine if this method has been successful.
Remarks
It is recommend to use the GetStat method to identify the specific reason for the method's failure, if any.
Example
