dimension
Dimensions of the neighborhood used to detect edges (Dimension x Dimension), in pixels. This parameter only accepts positive values.
threshold
Threshold value used to determine which pixels are edge pixels. If the difference determined by the edge detector algorithm for a pixel is greater than this value, the pixel is an edge pixel. This parameter only accepts positive values.
edgeColor
Edge color.
backGroundColor
Non edge color.
Initializes a new EdgeDetectStatisticalCommand class object with explicit parameters.

Syntax

Visual Basic (Declaration) 
Public Function New( _
   ByVal dimension As Integer, _
   ByVal threshold As Integer, _
   ByVal edgeColor As RasterColor, _
   ByVal backGroundColor As RasterColor _
)
Visual Basic (Usage)Copy Code
Dim dimension As Integer
Dim threshold As Integer
Dim edgeColor As RasterColor
Dim backGroundColor As RasterColor
 
Dim instance As EdgeDetectStatisticalCommand(dimension, threshold, edgeColor, backGroundColor)
C# 
public EdgeDetectStatisticalCommand( 
   int dimension,
   int threshold,

)
C++/CLI 
public:
EdgeDetectStatisticalCommand( 
   int dimension,
   int threshold,
   RasterColor edgeColor,

)

Parameters

dimension
Dimensions of the neighborhood used to detect edges (Dimension x Dimension), in pixels. This parameter only accepts positive values.
threshold
Threshold value used to determine which pixels are edge pixels. If the difference determined by the edge detector algorithm for a pixel is greater than this value, the pixel is an edge pixel. This parameter only accepts positive values.
edgeColor
Edge color.
backGroundColor
Non edge color.

Example

Run the EdgeDetectStatisticalCommand on an image.
