Decrypt Property

Summary

Provides options for loading any encrypted file.

Syntax

Objective-C

C++/CLI

Java

Python

public CodecsDecryptOptions Decrypt { get; }

@property (nonatomic, assign) LTCodecsDecryptOptions Decrypt

public CodecsDecryptOptions getDecrypt()

public: 
property CodecsDecryptOptions Decrypt { 
   bool get(); 
}

Decrypt # get  (CodecsLoadOptions)

Property Value

Class containing password values used to decrypt files.

Remarks

Provide the password for decrypting files using this property or through the RasterCodecs.DecryptPassword event.

The RasterCodecs.Pdf.Load.Password property can also be used for loading encrypted PDF files.

The difference is that RasterCodecs.Decrypt.Password can be used for decrypting any files, whereas RasterCodecs.Pdf.Load.Password can be used to only decrypt PDF files.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
 
using Leadtools.ImageProcessing.Core; 
using Leadtools.Pdf; 
 
public void CodecsLoadOptionsDecrypt_Example() 
{ 
   /* This sample loads Encrypted.docx, which is encrypted with the password 'MyPassword' */ 
   using (RasterCodecs codecs = new RasterCodecs()) 
   { 
      string srcFile = @"Encrypted.docx"; 
 
      codecs.Options.Load.Decrypt.Password = "MyPassword"; 
      codecs.Options.Load.AllPages = true; 
 
      using (RasterImage image = codecs.Load(srcFile)) 
      { 
         codecs.Save(image, srcFile + ".tif", RasterImageFormat.TifLzw, 0); 
      } 
   } 
}
