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

GetBlockRight Method (GdPictureSegmenter)

In This Topic
Returns the right x-coordinate of the bounding box of the specified block, that is a part of the segmentation result specified by its index.

This method uses a coordinate system, where the origin is in the top-left corner of the processed image and the units are pixels.

Syntax
'Declaration

 


Public Function GetBlockRight( _

   ByVal SegmentationResultID As String, _

   ByVal BlockIdx As Integer _

) As Integer
public int GetBlockRight( 

   string SegmentationResultID,

   int BlockIdx

)
public function GetBlockRight( 

    SegmentationResultID: String;

    BlockIdx: Integer

): Integer; 
public function GetBlockRight( 

   SegmentationResultID : String,

   BlockIdx : int

) : int;
public: int GetBlockRight( 

   string* SegmentationResultID,

   int BlockIdx

) 
public:

int GetBlockRight( 

   String^ SegmentationResultID,

   int BlockIdx

)

Parameters

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

Return Value

The right x-coordinate of the block's bounding box, in pixels.

The GetStat method can be subsequently used 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.

Please note, that the origin of the used coordinate system is in the top-left corner of the processed image and the used units are pixels.
