GdPicture.NET.14
GdPicture14 Namespace / GdPictureSegmenter Class / RunSegmentation Method / RunSegmentation(String) Method
A unique result identifier of the executed segmentation process, that is used to identify the segmentation result. You can define your preferable value. If you leave this parameter null or empty, a new identifier is automatically generated.
Example





In This Topic
RunSegmentation(String) Method
In This Topic
Runs the segmentation process on the image previously set by the GdPictureSegmenter.SetImage method within the current GdPictureSegmenter object. You are allowed to set the custom result identifier you prefer using this method. The result of this process, identifiable by this custom ID, is internally attached to the current GdPictureSegmenter object as well.
Syntax
'Declaration
 

Public Overloads Function RunSegmentation( _
   ByVal SegmentationResuldID As String _
) As String
public string RunSegmentation( 
   string SegmentationResuldID
)
public function RunSegmentation( 
    SegmentationResuldID: String
): String; 
public function RunSegmentation( 
   SegmentationResuldID : String
) : String;
public: string* RunSegmentation( 
   string* SegmentationResuldID
) 
public:
String^ RunSegmentation( 
   String^ SegmentationResuldID
)

Parameters

SegmentationResuldID
A unique result identifier of the executed segmentation process, that is used to identify the segmentation result. You can define your preferable value. If you leave this parameter null or empty, a new identifier is automatically generated.

Return Value

A unique result identifier of the executed segmentation process. If the method has been successfully followed, then the custom identifier passed as a parameter is returned, if it is properly defined.

The GdPictureSegmenter.GetStat method can be subsequently used 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.

Please ensure that you have set the required image before you start the new segmentation process. This method uses the image object previously set by GdPictureSegmenter.SetImage method. Setting up an image is a mandatory step before running any segmentation process.

Also be aware, that you can only reuse the result ID if you first release it using the GdPictureSegmenter.ReleaseSegmentationResult method before the next use. Releasing already used segmentation results can improve the memory management if you run more segmentation processes in a row.
