Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg; 
 
 
private void Codecs_LoadSavePage(object sender, CodecsPageEventArgs e) 
{ 
	if (e.State == CodecsPageEventState.After) 
		Console.WriteLine("The image has been processed"); 
	else 
		Console.WriteLine("The image has not processed yet"); 
 
	if (e.Page > 5) 
		e.Command = CodecsPageEventCommand.Stop; 
 
	Console.WriteLine("File name is: {0}", e.FileName); 
	if (e.Image != null) 
		Console.WriteLine("The Image width and height is: {0},{1}", e.Image.Width, e.Image.Height); 
	Console.WriteLine("Page Index is: {0}", e.Page); 
	Console.WriteLine("Page Count is: {0}", e.PageCount); 
} 
		public void LoadPageExample() 
{ 
	RasterCodecs codecs = new RasterCodecs(); 
 
	codecs.LoadPage += new EventHandler<CodecsPageEventArgs>(Codecs_LoadSavePage); 
	codecs.SavePage += new EventHandler<CodecsPageEventArgs>(Codecs_LoadSavePage); 
 
	RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp")); 
	codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "loadsave.jpg"), RasterImageFormat.Jpeg, image.BitsPerPixel); 
 
	codecs.LoadPage -= new EventHandler<CodecsPageEventArgs>(Codecs_LoadSavePage); 
	codecs.SavePage -= new EventHandler<CodecsPageEventArgs>(Codecs_LoadSavePage); 
 
	// Clean up 
	codecs.Dispose(); 
	image.Dispose();
