SmoothEdgesCommand Class

Summary

Smoothes the rough edges in the image.

Syntax
C#
VB
Java
Objective-C
C++
public class SmoothEdgesCommand : RasterCommand 
Public Class SmoothEdgesCommand  
   Inherits RasterCommand 
@interface LTSmoothEdgesCommand : LTRasterCommand 
public class SmoothEdgesCommand extends RasterCommand 
public ref class SmoothEdgesCommand : public RasterCommand   

Remarks
  • This command performs edge detection, then smoothes those edges that are found. The other points of the image are unchanged.
  • 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.

Example

Run the SmoothEdgesCommand on an image.

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   SmoothEdgesCommand command = new SmoothEdgesCommand(); 
   command.Amount = 75; 
   command.Threshold = 0; 
   // Apply the Smooth Edge effect to the image. 
   command.Run(image);
