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

For more information, refer to Introduction to Image Processing With LEADTOOLS.

This example will convert an image to a thumbnail size before saving it to disk.
