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 EdgeDetectorCommand class object with explicit parameters.

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 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 EdgeDetectorCommand on an image.

Public Sub EdgeDetectorConstructorExample()
   RasterCodecs.Startup()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg")

   ' Prepare the command
   Dim command As EdgeDetectorCommand
   command = New EdgeDetectorCommand(60, EdgeDetectorCommandType.Laplace2)
   ' find the edges of the image.
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
