EdgeDetectStatisticalCommand Constructor(int,int,RasterColor,RasterColor)

Summary

Initializes a new EdgeDetectStatisticalCommand class object with explicit parameters.

Syntax
C#
VB
Objective-C
C++
Java
Public Function New( _ 
   ByVal dimension As Integer, _ 
   ByVal threshold As Integer, _ 
   ByVal edgeColor As RasterColor, _ 
   ByVal backGroundColor As RasterColor _ 
) 
- (instancetype)initWithDimension:(NSUInteger)dimension 
                        threshold:(NSInteger)threshold 
                        edgeColor:(LTRasterColor*)edgeColor 
                  backgroundColor:(LTRasterColor *)backgroundColor 
public EdgeDetectStatisticalCommand( 
   int dimension,  
   int threshold,  
   RasterColor edgeColor,  
   RasterColor backGroundColor 
) 
public: 
EdgeDetectStatisticalCommand(  
   int dimension, 
   int threshold, 
   RasterColor edgeColor, 
   RasterColor backGroundColor 
) 

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.
