public class SizeCommand : RasterCommand, IRasterCommand

'Declaration
 
Public Class SizeCommand 
   Inherits RasterCommand
   Implements IRasterCommand

'Usage
 
Dim instance As SizeCommand

public sealed class SizeCommand : IRasterCommand

@interface LTSizeCommand : LTRasterCommand

public class SizeCommand extends RasterCommand

function Leadtools.ImageProcessing.SizeCommand()

public ref class SizeCommand : public RasterCommand, IRasterCommand

This command resizes the image passed to the RasterCommand.Run method. If you want to keep the original-size image and create a new resized version, use ResizeCommand.
