SmoothEdgesCommand Class

Summary

Smoothes the rough edges in the image.

Syntax

Objective-C

C++/CLI

Java

Python

public class SmoothEdgesCommand : RasterCommand

@interface LTSmoothEdgesCommand : LTRasterCommand

public class SmoothEdgesCommand 
    extends RasterCommand

public ref class SmoothEdgesCommand : public RasterCommand

class SmoothEdgesCommand(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.

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void SmoothEdgesCommandExample()

   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   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);
