SizeCommand Class

Show in webframe
Example 







Members 
Resizes an image to a new width and height.
Object Model
Syntax
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  
Remarks

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.
