Leadtools.ImageProcessing.Core Namespace : MinMaxBitsCommand Class



Gets the low and high bits of the values present in a 12 or 16-bit grayscale or a 48 or 64-bit color image. This class is available in the Medical Toolkits. Supported in Silverlight, Windows Phone 7

Object Model

MinMaxBitsCommand Class

Syntax

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

Example

Run the Leadtools.ImageProcessing.Core.MinMaxBitsCommand on an image and gets the minimum and maximum bits for an image.

Public Sub MinMaxBitsCommandExample()
   Dim codecs As New RasterCodecs()
   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ImageProcessingDemo\Beauty16.jpg"))

   ' Prepare the command
   Dim command As MinMaxBitsCommand = New MinMaxBitsCommand
   Dim MinimumBit As Integer   'the minimum value.
   Dim MaximumBit As Integer   'the maximum value.

   MinimumBit = 0

   'Get min/max bits.
   command.Run(leadImage)
   MinimumBit = command.MinimumBit
   MaximumBit = command.MaximumBit
   MessageBox.Show("The Minuimum Bit is : " + MinimumBit.ToString() + ", The Maximum Bit is : " + MaximumBit.ToString())

SilverlightVBCopy Code

   ' Prepare the command
   Dim command As MinMaxBitsCommand = New MinMaxBitsCommand()
   Dim MinimumBit As Integer = 0 'the low bit variable.
   Dim MaximumBit As Integer = 0 'the high bit variable.
   'Get min/max bits.

   image.Dispose()
End Sub

Remarks

  • The minimum and maximum bit values can be used to specify the range of useful bits and to create a lookup table, for use in the WindowLevelCommand class.
  • This command 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.
