The Leadtools.ImageProcessing.RasterCommand to be applied to the image.

Example

This example inverts the image and returns the inverted image into Leadtools.RasterImage object.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Web.Controls; 
using Leadtools.ImageProcessing; 
 
public void WebImageViewer_FlipCommand() 
{ 
   WebImageViewer mainWebImageViewer = new WebImageViewer(); 
   FlipCommand cmd = new FlipCommand(); 
 
   mainWebImageViewer.ImageDataChanged += new EventHandler(mainWebImageViewer_ImageDataChanged); 
   mainWebImageViewer.ApplyCommand(cmd); 
   mainWebImageViewer.ImageDataChanged -= new EventHandler(mainWebImageViewer_ImageDataChanged); 
 
   string imageUrl = mainWebImageViewer.ImageInfo.Url; 
 
   if (mainWebImageViewer.ImageInfo.CacheFileName != string.Empty) 
      imageUrl = mainWebImageViewer.ImageInfo.CacheFileName; 
 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string filePath = mainWebImageViewer.Page.MapPath(imageUrl); 
   int pageNumber = mainWebImageViewer.ImageInfo.PageIndex + 1; 
 
   RasterImage image = codecs.Load(filePath, 0, CodecsLoadByteOrder.BgrOrGray, pageNumber, pageNumber); 
} 
 
void mainWebImageViewer_ImageDataChanged(object sender, EventArgs e) 
{ 
   // "Image Data changed"... 
}
