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

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

'Usage
 
Dim instance As ConvertSignedToUnsignedCommand

public sealed class ConvertSignedToUnsignedCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Core.ConvertSignedToUnsignedCommand()

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

The image may contain negative pixel values and LEADTOOLS will paint/process the image incorrectly. To use this image correctly the negative pixels should be converted, if it contains negative pixels (if Leadtools.RasterImage.Signed is True).
If the Leadtools.RasterImage.Signed is set to True, this method will shift the color values in the image according to Type property.
The method will also update the Leadtools.RasterImage.MinValue and Leadtools.RasterImage.MaxValue properties of the Leadtools.RasterImage.
.
This method 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 does not support 32-bit grayscale images.
