Hello.

Environment
 - VB .Net 2005
 - LeadTool V15 ( 15.0.1.3)

I have a problem about GrayscaleMode(RasterImage Class)
I Load TIF File(16bit) and run ApplyLinearVOILut Command.

At First, grayscalemode property of the image was "OrderedNormal"
After run ApplyLinearVoiLut Command , grayscalemode property change into "NotOrdered" or "OrderedInverse"

I make this code under MouseMoveEvent
this is code __________________________________
                    Dim VoiCmd As ApplyLinearVoiLookupTableCommand = New ApplyLinearVoiLookupTableCommand()

                    Debug.Print("Image Grayscale Order : " + Image.GrayscaleMode.ToString)
                    If _IsReverse Then   'Check inverted
                        VoiCmd.Flags = VoiLookupTableCommandFlags.ReverseOrder
                    Else
                        VoiCmd.Flags = VoiLookupTableCommandFlags.UpdateMinMax
                    End If

                    VoiCmd.Center = _Level
                    VoiCmd.Width = _Width
                    VoiCmd.Run(Image)


I want to keep grayscalemode of the image.
Please help me.

To keep the GrayscaleMode of the image, you need to use the GrayscaleCommand after calling the ApplyLinearVoiLookupTableCommand:
+-----+
Dim gr As New Leadtools.ImageProcessing.GrayscaleCommand(16)
gr.Run(RasterImageViewer1.Image)
+-----+
