C++ API to Export EML to RTF
Transform EML to RTF within C++ application without requiring Microsoft Word or Outlook
Why to Convert
As a C++ developer, you may need to add email conversion features inside your applications. Email conversion is the process of transforming emails from one format to another. This is often done to make the emails more compatible with different email clients or to make them easier to read.
How Aspose.Total Helps for EML to RTF Conversion
Aspose.Total for C++ is a suite of APIs that provides developers with the tools they need to create, edit, and convert documents. It includes two APIs specifically designed for email conversion: Aspose.Email for C++ and Aspose.Words for C++.
Using Aspose.Email for C++, you can convert EML file format to HTML. After that, by using Aspose.Words for C++ API, you can export HTML to RTF. Both APIs come under Aspose.Total for C++ package. This makes it easy to convert emails from one format to another without having to use multiple APIs.
Aspose.Total for C++ also provides a number of other features that make it a great choice for developers. It supports a wide range of file formats, including Microsoft Office, OpenOffice, PDF, and more. It also provides a number of features for manipulating documents, such as text extraction, document comparison, and more.
Overall, Aspose.Total for C++ is an excellent choice for developers who need to add email conversion features to their applications. It provides a comprehensive suite of APIs that make it easy to convert emails from one format to another.
C++ API to Convert EML to RTF
- Open EML file using MailMessage class reference
- Convert EML to HTML by using Save member function
- Load HTML by using Document class
- Save the document to RTF format using Save method and set Rtf as SaveFormat
Get Started with C++ File Format 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 the EML file to be converted
System::SharedPtr<MailMessage> msg = MailMessage::Load(u"sourceFile.eml");
// save EML as a HTML
msg->Save(u"HtmlOutput.html", SaveOptions::get_DefaultHtml());
// load HTML with an instance of Document
System::SharedPtr<Document> doc = System::MakeObject<Document>(u"HtmlOutput.html");
// call save method while passing Rtf as save format
doc->Save(u"convertedFile.Rtf");
Parse EML File via C++
Not only you can convert your EML to RTF, but you can read, manipulate, and parse EML document. You can get subject, address, body, recipients information of the email by using MapiMessage class of Aspose.Email for C++ API. For example, you can check for a specific sender email for the conversion by using get_SenderEmailAddress() property.
// create an instance of MapiMessage from file
System::SharedPtr<MapiMessage> msg = MapiMessage::FromFile(dataDir + L"message.eml");
// get subject
System::Console::WriteLine(System::String(L"Subject:") + msg->get_Subject());
// get from address
System::Console::WriteLine(System::String(L"From:") + msg->get_SenderEmailAddress());
// get body
System::Console::WriteLine(System::String(L"Body") + msg->get_Body());
// get recipients information
System::Console::WriteLine(System::String(L"Recipient: ") + msg->get_Recipients());
C++ API to Restrict RTF File Format Editing
You can also add document protection features in your app while exporting the document from EML to RTF. Adding protection to your document is a simple process, as all you need to do is apply the protection method to your document. You can set protection type to ReadOnly to restrict the user to edit the document.
// create a new document and protect it with a password.
auto doc = System::MakeObject<Document>();
// apply Document Protection.
doc->Protect(ProtectionType::ReadOnly, u"password");
// save the document.
doc->Save(u"DocumentProtection.PasswordProtection.Rtf");
