public EdgeDetectEffectCommand( 
   int level,
   int threshold,
   EdgeDetectEffectCommandType type
)

'Declaration
 
Public Function New( _
   ByVal level As Integer, _
   ByVal threshold As Integer, _
   ByVal type As EdgeDetectEffectCommandType _
)

'Usage
 
Dim level As Integer
Dim threshold As Integer
Dim type As EdgeDetectEffectCommandType
 
Dim instance As New EdgeDetectEffectCommand(level, threshold, type)

public EdgeDetectEffectCommand( 
   int level,
   int threshold,
   EdgeDetectEffectCommandType type
)

function EdgeDetectEffectCommand( 
   level ,
   threshold ,
   type 
)

public:
EdgeDetectEffectCommand( 
   int level,
   int threshold,
   EdgeDetectEffectCommandType type
)

Parameters

level: Level value used to determine the brightness of the edges. Standard value is 50. Range between 1 and 100. Big values will produce bright edges.
threshold: Threshold value used to determine which pixels are going to be filtered. If the difference determined for a pixel is less than this value, the pixel is set to 0. If the difference is greater, the filter will be applied to the pixel. This parameter only accepts positive values.
type: Flag that indicates the type of edge to generate.
