using Leadtools.ImageProcessing; 
 
 
public void SizeCommandExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
	string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "SizeCommand.bmp"); 
 
	// Load the source image from disk 
	RasterImage image = codecs.Load(srcFileName); 
	SizeCommand command = new SizeCommand(); 
	command.Width = 128; 
	command.Height = 128; 
	command.Flags = RasterSizeFlags.Resample; 
	command.Run(image);
