   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

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

Remarks

This command takes an image and divides it into many blocks, and then examines each block to determine if it is background and if it is in-focus or out-of-focus.
This command supports 8,12, 16-bit grayscale images and 24, 32-bit colored images.
