public EdgeDetectorCommand( 
   int threshold,
   EdgeDetectorCommandType filter
)

'Declaration
 
Public Function New( _
   ByVal threshold As Integer, _
   ByVal filter As EdgeDetectorCommandType _
)

'Usage
 
Dim threshold As Integer
Dim filter As EdgeDetectorCommandType
 
Dim instance As New EdgeDetectorCommand(threshold, filter)

public EdgeDetectorCommand( 
   int threshold,
   EdgeDetectorCommandType filter
)

function EdgeDetectorCommand( 
   threshold ,
   filter 
)

public:
EdgeDetectorCommand( 
   int threshold,
   EdgeDetectorCommandType filter
)

Parameters

threshold: Threshold value used to determine which pixels are edge pixels. If the difference determined for a pixel is greater than this value, the pixel is an edge pixel. This parameter only accepts positive values.
filter: Flag that indicates which edge detection filter to apply.
