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

'Declaration

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

'Usage

Dim instance As ConvertUnsignedToSignedCommand

public sealed class ConvertUnsignedToSignedCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTConvertUnsignedToSignedCommand : LTRasterCommand

public class ConvertUnsignedToSignedCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.ConvertUnsignedToSignedCommand()

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

This class updates the minimum and maximum values of the image with new values that consider the image's new signed values.
This class 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.

Run the ConvertUnsignedToSignedCommand on an image. The passed image must be Unsigned image.
