public class StatisticsInformationCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration
 
Public Class StatisticsInformationCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As StatisticsInformationCommand

public sealed class StatisticsInformationCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Effects.StatisticsInformationCommand()

public ref class StatisticsInformationCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

This command calculates statistical information about the image.
The start and end values designate the range of colors that will be taken in consideration for producing the results. Only the values between Start and End are used for the calculation of the results. The range of each one depends on the bits per pixel of the image: in the case of 8 bits per component (RGB), the range is between 0 and 255; for 16 bits, the range is 0 through 65535;and from -32768 to 32767 for signed images; and for 12 bits, the range is 0 through 4095.
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 support signed data images.
This command does not support 32-bit grayscale images.
