GetParagraphCount Method (GdPictureSegmenter)

In This Topic
Returns the number of paragraphs within the segmentation result specified by its index.
Syntax
'Declaration
 

Public Function GetParagraphCount( _
   ByVal SegmentationResultID As String _
) As Integer
public int GetParagraphCount( 
   string SegmentationResultID
)
public function GetParagraphCount( 
    SegmentationResultID: String
): Integer; 
public function GetParagraphCount( 
   SegmentationResultID : String
) : int;
public: int GetParagraphCount( 
   string* SegmentationResultID
) 
public:
int GetParagraphCount( 
   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 paragraphs. Please always use the GdPictureSegmenter.GetStat method to determine if this method has been successful.
Remarks
It is recommend to use the GdPictureSegmenter.GetStat method to identify the specific reason for the method's failure, if any.
