'Declaration
 
Public Function GetWordCount( _
   ByVal SegmentationResultID As String _
) As Integer

public int GetWordCount( 
   string SegmentationResultID
)

public function GetWordCount( 
    SegmentationResultID: String
): Integer;

public function GetWordCount( 
   SegmentationResultID : String
) : int;

public: int GetWordCount( 
   string* SegmentationResultID
)

public:
int GetWordCount( 
   String^ SegmentationResultID
)

Parameters

SegmentationResultID: The unique result identifier of the executed segmentation process obtained by the GdPictureSegmenter.RunSegmentation method.

Return Value

The number of detected words. Please always use the GdPictureSegmenter.GetStat method to determine if this method has been successful.

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