ContourFilterCommand Constructor(Int32,Int32,Int32,ContourFilterCommandType)

Example 





Threshold of the gradient magnitude. Values below this will be considered as background, and will be set to 0. Values can be from 1 to 254. A lower threshold provides a better quality image. Default is 15.
Maximum angle for the thinning algorithm. Values can be from 1 to 64. Default is 35.
Maximum error for approximation algorithm. Values can be from 0 to 255. Default is 5. This parameter is only valid if the type parameter is set to ApproxColor.
Flag that controls the resulting image. This value tells the command what process to complete before returning.
Initializes a new ContourFilterCommand class object with explicit parameters. .NET support

Parameters

threshold
Threshold of the gradient magnitude. Values below this will be considered as background, and will be set to 0. Values can be from 1 to 254. A lower threshold provides a better quality image. Default is 15.
deltaDirection
Maximum angle for the thinning algorithm. Values can be from 1 to 64. Default is 35.
maximumError
Maximum error for approximation algorithm. Values can be from 0 to 255. Default is 5. This parameter is only valid if the type parameter is set to ApproxColor.
type
Flag that controls the resulting image. This value tells the command what process to complete before returning.
Example
 
Public Sub ContourFilterConstructorExample()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg"))

   ' Prepare the command
   Dim command As ContourFilterCommand
   command = New ContourFilterCommand(15, 35, 5, ContourFilterCommandType.LinkColor)
   command.Run(leadImage)
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24)

End Sub

Public NotInheritable Class LEAD_VARS
   Public Const ImagesDir As String = "C:\Users\Public\Documents\LEADTOOLS Images"
End Class
public void ContourFilterConstructorExample()
   {
      // Load an image
      RasterCodecs codecs = new RasterCodecs();
      codecs.ThrowExceptionsOnInvalidImages = true;

      RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg"), 16, CodecsLoadByteOrder.BgrOrGray, 1, 1);

      // Prepare the command
      ContourFilterCommand command = new ContourFilterCommand(15, 35, 5, ContourFilterCommandType.LinkColor);
      command.Run(image);
      codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);

   }

static class LEAD_VARS
{
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images";
}
