public class ConvertUnsignedToSignedCommand : RasterCommand 
public sealed class ConvertUnsignedToSignedCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand   
@interface LTConvertUnsignedToSignedCommand : LTRasterCommand 
public class ConvertUnsignedToSignedCommand extends RasterCommand 
function Leadtools.ImageProcessing.Core.ConvertUnsignedToSignedCommand() 

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.
