ImageProcessing.Core.ConvertUnsignedToSignedCommand
   Public Sub ConvertUnsignedToSignedCommandExample()
      RasterCodecs.Startup()
      Dim codecs As New RasterCodecs()
      codecs.ThrowExceptionsOnInvalidImages = True

C#Copy Code
ImageProcessing.Core.ConvertUnsignedToSignedCommand 
      public void ConvertUnsignedToSignedCommandExample() 
      { 
         // Load an image 
         RasterCodecs.Startup(); 
         RasterCodecs codecs = new RasterCodecs(); 
         codecs.ThrowExceptionsOnInvalidImages = true; 
 
         RasterImage image = codecs.Load(@"C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Master.jpg");

         ConvertUnsignedToSignedCommand command = new ConvertUnsignedToSignedCommand(); 
         command.Type   = ConvertUnsignedToSignedCommandType.ProcessRangeOnly; 
         //convert image to signed. 
         command.Run(image); 
 
         RasterCodecs.Shutdown(); 
      }

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.
