SegmentCommand Class

Divides the image into segments where each segment's pixels have approximately the same color (homogenous color). This command is available in the Raster Pro and above toolkits. Supported in Silverlight, Windows Phone 7

Object Model

SegmentCommand Class

Syntax

Visual Basic (Declaration) 
Public Class SegmentCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage)Copy Code
Dim instance As SegmentCommand
C# 
public class SegmentCommand : Leadtools.ImageProcessing.RasterCommand, IRasterCommand  
C++/CLI 
public ref class SegmentCommand : public Leadtools.ImageProcessing.RasterCommand, IRasterCommand  

Example

Run the Leadtools.ImageProcessing.Color.SegmentCommand on an image.

Remarks

  • This command divides the images into segments according to its pixel values . The segment shapes will be arbitrary. Adjacent pixels with approximately the same values are put together into homogenous segments. The command may be performed on the RGB and YUV color spaces.
  • This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support signed data images.
  • This command does not support 32-bit grayscale images.
