@interface LTConvertUnsignedToSignedCommand : LTRasterCommand

public class ConvertUnsignedToSignedCommand extends RasterCommand

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.
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.

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); 
 
}

{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images";
