DynamicBinaryCommand Constructor(Int32,Int32)
See Also  Example



dimension
Dimensions of the neighborhood used when evaluating each pixel (Dimension x Dimension), in pixels. This should be at least 1.
localContrast
Local contrast threshold. If the contrast of the area surrounding the pixel is less than the LocalContrast property, the pixel is converted to black or white using a global pre-calculated threshold. If the contrast of the area surrounding the pixel is higher than the LocalContrast property, the local threshold value is calculated and used. The range for the LocalContrast property is 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit.
Initializes a new DynamicBinaryCommand class object with explicit parameters.

Parameters

dimension
Dimensions of the neighborhood used when evaluating each pixel (Dimension x Dimension), in pixels. This should be at least 1.
localContrast
Local contrast threshold. If the contrast of the area surrounding the pixel is less than the LocalContrast property, the pixel is converted to black or white using a global pre-calculated threshold. If the contrast of the area surrounding the pixel is higher than the LocalContrast property, the local threshold value is calculated and used. The range for the LocalContrast property is 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit.

Example

Run the DynamicBinaryCommand on an image.

Visual BasicCopy Code
Public Sub DynamicBinaryConstructorExample()
   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 DynamicBinaryCommand = New DynamicBinaryCommand(8, 16)
   ' convert it into a black and white image without changing its bits per pixel.
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C#Copy Code
public void DynamicBinaryConstructorExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg"); 
 
   // Prepare the command 
   DynamicBinaryCommand command = new DynamicBinaryCommand(8, 16); 
   // convert it into a black and white image without changing its bits per pixel. 
   command.Run(image); 
   codecs.Save(image, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24); 
 
   RasterCodecs.Shutdown(); 
}
