public ref class ConvertUnsignedToSignedCommand : public RasterCommand

Remarks

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

Example

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

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void ConvertUnsignedToSignedCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE2.dcm")); 
 
   // Prepare the command 
   ConvertUnsignedToSignedCommand command = new ConvertUnsignedToSignedCommand(); 
   command.Type = ConvertUnsignedToSignedCommandType.ProcessRangeOnly; 
   //convert image to signed. 
   command.Run(image); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS21\Resources\Images"; 
}

Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.Core 
 
Public Sub ConvertUnsignedToSignedCommandExample() 
   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE2.dcm")) 
 
   ' Prepare the command 
   Dim command As ConvertUnsignedToSignedCommand = New ConvertUnsignedToSignedCommand 
   command.Type = ConvertUnsignedToSignedCommandType.ProcessRangeOnly 
   'convert image to signed. 
   command.Run(leadImage) 
 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
   Public Const ImagesDir As String = "C:\LEADTOOLS21\Resources\Images" 
End Class
