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

'Declaration

Public Class MinMaxBitsCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As MinMaxBitsCommand

public sealed class MinMaxBitsCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTMinMaxBitsCommand : LTRasterCommand

public class MinMaxBitsCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.MinMaxBitsCommand()

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

The minimum and maximum bit values can be used to specify the range of useful bits and to create a lookup table, for use in the WindowLevelCommand class.
This command supports 12 and 16-bit grayscale images. Support for 12 and 16-bit grayscale images is available only in the Document/Medical toolkits.
This command does not support 32-bit grayscale images.
LEADTOOLS supports two types of LUTs for 10-16-bit grayscale images (8-bit LUT and 16-bit LUT). Typical grayscale image display and processing is done using an 8-bit LUT. But, you can also use a 16-bit LUT, which offers more precision. Some special video cards and monitors also support display of grayscale images using a 16-bit LUT.

For more information, refer to Introduction to Image Processing With LEADTOOLS.
For more information, refer to Grayscale Images.

In Silverlight versions of LEADTOOLS, this image processing command will fail if the image data for the RasterImage object is stored internally using a Silverlight WriteableBitmap object. For more information, refer to Image Processing Command Limitations in Silverlight.

Run the MinMaxBitsCommand on an image and gets the minimum and maximum bits for an image.
