Object Model

ConvertUnsignedToSignedCommand Class

Syntax

Visual Basic (Declaration) 
Public Class ConvertUnsignedToSignedCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage)Copy Code
Dim instance As ConvertUnsignedToSignedCommand
C# 
public class ConvertUnsignedToSignedCommand : Leadtools.ImageProcessing.RasterCommand, IRasterCommand 
C++/CLI 
public ref class ConvertUnsignedToSignedCommand : public Leadtools.ImageProcessing.RasterCommand, IRasterCommand 

Example

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

Visual BasicCopy Code
Public Sub ConvertUnsignedToSignedCommandExample()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Master.jpg"))

   ' Prepare the command
   Dim command As ConvertUnsignedToSignedCommand = New ConvertUnsignedToSignedCommand
   command.Type = ConvertUnsignedToSignedCommandType.ProcessRangeOnly
   'convert image to signed.
   command.Run(leadImage)

End Sub

      //convert image to signed.

   ConvertUnsignedToSignedCommand command = new ConvertUnsignedToSignedCommand();

Public Sub ConvertUnsignedToSignedCommandExample(ByVal image As RasterImage)
   ' Prepare the command
   Dim command As ConvertUnsignedToSignedCommand = New ConvertUnsignedToSignedCommand()
   command.Type = ConvertUnsignedToSignedCommandType.ProcessRangeOnly
   'convert image to signed.
   command.Run(image)
   image.Dispose()
End Sub

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.
