Leadtools.ImageProcessing.Core Namespace : ResizeInterpolateCommand Class



Applies different kinds of algorithms on images to resize them into the desired size.

Syntax

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

Example

Run the ResizeCommand on an image.

Visual BasicCopy Code
Public Sub ResizeCommandExample()
   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 ResizeInterpolateCommand = New ResizeInterpolateCommand()

   ' Resize the bitmap into 50 pixels x 50 pixels using the Bilinear algorithm.
   command.Width = 50
   command.Height = 50
   command.ResizeType = ResizeInterpolateCommandType.Bilinear
   command.Run(leadImage)

   RasterCodecs.Shutdown()
End Sub
C#Copy Code
public void ResizeCommandExample() 
{ 
   // 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 
   ResizeInterpolateCommand command = new ResizeInterpolateCommand(); 
 
   // Resize the bitmap into 50 pixels x 50 pixels using the Bilinear algorithm. 
   command.Width = 50; 
   command.Height = 50; 
   command.ResizeType = ResizeInterpolateCommandType.Bilinear; 
   command.Run(image); 
 
   RasterCodecs.Shutdown(); 
}

Remarks

  • This command keeps the same bitmap handle and resizes the bitmap that it references.
  • 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.
