MinMaxBitsCommand Class
See Also  Members   Example 
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.

Syntax

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

Example

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

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

   Dim leadImage As RasterImage = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "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
   MaximumBit = 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())

   RasterCodecs.Shutdown()
End Sub
C#Copy Code
public void MinMaxBitsCommandExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Beauty16.jpg"); 
 
   // Prepare the command 
   MinMaxBitsCommand command  = new MinMaxBitsCommand(); 
   int MinimumBit = 0; //the low bit variable. 
   int MaximumBit = 0; //the high bit variable. 
   //Get min/max bits. 
   command.Run(image); 
   MinimumBit = command.MinimumBit; 
   MaximumBit = command.MaximumBit; 
   MessageBox.Show("The Minuimum Bit is : " + MinimumBit.ToString() + ", The Maximum Bit is : " + MaximumBit.ToString()); 
 
   RasterCodecs.Shutdown(); 
}

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.
