EdgeDetectorCommand Constructor(Int32,EdgeDetectorCommandType)
See Also  Example
Leadtools.ImageProcessing.Effects Namespace > EdgeDetectorCommand Class > EdgeDetectorCommand Constructor : EdgeDetectorCommand Constructor(Int32,EdgeDetectorCommandType)



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.
Initializes a new Leadtools.ImageProcessing.Effects.EdgeDetectorCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7

Syntax

Visual Basic (Declaration) 
Public Function New( _
   ByVal threshold As Integer, _
   ByVal filter As EdgeDetectorCommandType _
)
Visual Basic (Usage)Copy Code
Dim threshold As Integer
Dim filter As EdgeDetectorCommandType
 
Dim instance As New EdgeDetectorCommand(threshold, filter)
C# 
public EdgeDetectorCommand( 
   int threshold,
   EdgeDetectorCommandType filter
)
C++/CLI 
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.

Example

Run the Leadtools.ImageProcessing.Effects.EdgeDetectorCommand on an image.
