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

GdPicture14 Namespace / GdPictureSegmenter Class / GetCharacterRight Method

GetCharacterRight Method (GdPictureSegmenter)

In This Topic
Returns the right x-coordinate of the bounding box of the specified character, 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 GetCharacterRight( _

   ByVal SegmentationResultID As String, _

   ByVal CharacterIdx As Integer _

) As Integer
public int GetCharacterRight( 

   string SegmentationResultID,

   int CharacterIdx

)
public function GetCharacterRight( 

    SegmentationResultID: String;

    CharacterIdx: Integer

): Integer; 
public function GetCharacterRight( 

   SegmentationResultID : String,

   CharacterIdx : int

) : int;
public: int GetCharacterRight( 

   string* SegmentationResultID,

   int CharacterIdx

) 
public:

int GetCharacterRight( 

   String^ SegmentationResultID,

   int CharacterIdx

)

Parameters

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

Return Value

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

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.

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.
