Example

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

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using LeadtoolsExamples.Common; 
 
public void SizeCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = Path.Combine(ImagesPath.Path, "Image1.cmp"); 
   string destFileName = Path.Combine(ImagesPath.Path, "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); 
 
   // Save the image back to disk 
   codecs.Save(image, destFileName, RasterImageFormat.Bmp, 8); 
 
   // Clean Up 
   image.Dispose(); 
   codecs.Dispose(); 
}
