Leadtools.ImageProcessing.Core Namespace : MaximumCommand Class



Erodes dark objects by the specified amount. This command is available in the Document/Medical Toolkits.

Syntax

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

Example

Run the MaximumCommand on an image with a neighborhood Dimensions = 3x3 pixels.

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

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

   ' Prepare the command
   Dim command As MaximumCommand = New MaximumCommand
   'Apply Maximum filter.
   command.Dimension = 3

   command.Run(leadImage)

   RasterCodecs.Shutdown()
End Sub
C#Copy Code
public void MaximumCommandExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg"); 
 
   // Prepare the command 
   MaximumCommand command = new MaximumCommand(); 
   //Apply Maximum filter. 
   command.Dimension = 3; 
   command.Run(image); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • This command can process the whole image or a region of the image.
  • The effect can be controlled by specifying the size of the neighborhood that is used for calculating each pixel value. For example, for 8x8, set Dimension property (or the dimension parameter of the Constructor) to 8. Each pixel is replaced with the maximum value of its neighborhood.
  • This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support 32-bit grayscale images.
