Summary

Determines whether an image is blurred.

Syntax

Java

Objective-C

WinRT C#

C++

public class BlurDetectionCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

Public Class BlurDetectionCommand  
   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

public sealed class BlurDetectionCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

@interface LTBlurDetectionCommand : LTRasterCommand

public class BlurDetectionCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.BlurDetectionCommand()

public ref class BlurDetectionCommand : public Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand, Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

Remarks

This command takes an image and determines whether it is blurred. If it is blurred it calculates the amount of blurring.
This command supports 8-bit, 12-bit, and 16-bit grayscale images and 24-bit and 32-bit colored images.
