C++ API to Export MHTML to RTF
Render MHTML to RTF within C++ applications without requiring any third party application
Why to Convert MHTML to RTF?
MHTML (MIME HTML) is a web page archive format used to save web pages for offline viewing. It is a combination of HTML code and resources such as images, audio, and video. It is widely used for archiving web pages and email messages. However, MHTML is not suitable for editing or printing. Therefore, it is necessary to convert MHTML to RTF (Rich Text Format) for editing and printing purposes.

Firstly, you can use Aspose.PDF for C++ API to convert MHTML file format to DOC. Secondly, by using advanced Word Document Processing API Aspose.Words for C++, you can export DOC to RTF. Aspose.Total for C++ is a comprehensive suite of file format APIs that helps developers to create, manipulate, convert, and print documents without using any external applications. It supports a wide range of file formats, including PDF, Word, Excel, PowerPoint, Outlook, and more. Aspose.Total for C++ is a reliable and cost-effective solution for developers to automate their document processing tasks.
C++ API to Render MHTML to RTF
Get Started with C++ File Automation APIs
Install from command line as nuget install Aspose.Total.Cpp or via Package Manager Console of Visual Studio with Install-Package Aspose.Total.Cpp.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load MHTML file with an instance of Document class reference
auto doc = MakeObject<Document>(u"sourceFile.mhtml");
// save MHTML as a DOC
doc->Save(u"DocOutput.doc", SaveFormat::Doc);
// load DOC with an instance of Document
System::SharedPtr<Document> wordDoc = System::MakeObject<Document>(u"DocOutput.doc");
// save document as Rtf
wordDoc->Save(u"output.Rtf");
Change Password of MHTML Document via C++
In the process of rendering MHTML to RTF, you can open a password protected MHTML and also change its password. In order to change the password of a MHTML file, you must know the owner password of that document. You can load password protected PDF document with Aspose.PDF for C++ by specifying its owner password and use ChangePasswords method to change the password.
// load an existing MHTML Document
auto doc = MakeObject<Document>(L"input.mhtml", L"owner");
// change password of MHTML Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Restrict RTF File Editing via C++
You can also restrict RTF file editing using using Aspose.Words for C++ API. Sometimes you may need to limit the ability to edit a document and only allow certain actions with it. API enables you to control the way you restrict the content using the ProtectionType enumeration parameter. The following code example demonstrates how to restrict editing in a document so only editing in form fields is possible.
// load Doc with an instance of Document
auto doc = System::MakeObject<Document>("input.doc");
// document protection only works when document protection is turned and only editing in form fields is allowed.
doc->Protect(ProtectionType::AllowOnlyFormFields, u"password");
// save the protected document.
doc->Save(u"Protected.Rtf");
