C++ API to Export EML to EMF

Transform EML to EMF within C++ application without requiring Microsoft Word or Outlook

 

Are you are a C++ developer looking to add email conversion features inside your applications? 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 EMF. Both APIs come under Aspose.Total for C++ package.

C++ API to Convert EML to EMF

  1. Open EML file using MailMessage class reference
  2. Convert EML to HTML by using Save member function
  3. Load HTML by using Document class
  4. Save the document to EMF format using Save method and set Emf 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 Emf as save format
doc->Save(u"convertedFile.Emf");

Parse EML File via C++

Not only you can convert your EML to EMF, 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 EMF File Format Editing

You can also add document protection features in your app while exporting the document from EML to EMF. 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.Emf");

EML What is EML File Format?

EML file format represents email messages saved using Outlook and other relevant applications. Almost all emailing clients support this file format for its compliance with RFC-822 Internet Message Format Standard. Microsoft Outlook is the default software for opening EML message types. EML files can be used for saving to disc as well as sending out to recipients using communication protocols.

EMF What is EMF File Format?

Enhanced metafile format (EMF) stores graphical images device-independently. Metafiles of EMF comprises of variable-length records in chronological order that can render the stored image after parsing on any output device. These variable-length records can be definitions of enclosed objects, commands for drawing, and graphics properties critical to render the image accurately. When a device opens an EMF metafile using its own graphics environment, the proportions, dimensions, colors and other graphic properties of original image remains same regardless of the opening device platform.
