using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg; 
 
 
private static void DecryptPasswordExample() 
{ 
 
   /* This example loads an encrypted file using the Decrypt password event */ 
   using (RasterCodecs codecs = new RasterCodecs()) 
   { 
      string srcFile = @"Encrypted.docx"; 
 
      // Create a DecryptPassword handler  
      EventHandler<CodecsDecryptPasswordEventArgs> decryptPasswordHandler = (sender, e) => 
      { 
         /* You can also bring up a message box informing the user that the 'e.FileName' file is encrypted and needs a password */ 
         e.Password = "MyPassword"; 
         /* Or you can set 'e.Cancel = true' to cancel the load */ 
      }; 
 
      // Install the DecryptPassword event handler 
      codecs.DecryptPassword += decryptPasswordHandler; 
 
      codecs.Options.Load.AllPages = true; 
 
      using (RasterImage image = codecs.Load(srcFile)) 
      { 
         /* check that the image is not null to make sure the operation was not cancelled */ 
         if (image != null) 
            codecs.Save(image, srcFile + ".tif", RasterImageFormat.TifLzw, 0); 
      }
