'Declaration

Public Class SizeCommand 
   Inherits RasterCommand
   Implements IRasterCommand

'Usage

Dim instance As SizeCommand

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.
