C++ API to Export EML to EMF
Transform EML to EMF 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 changing the format of an email message from one type to another. For example, you may need to convert an email message from EML to HTML, or from HTML to EMF.
How Aspose.Total Helps for EML to EMF Conversion
Aspose.Total for C++ is a suite of APIs that provides developers with a comprehensive set of tools for creating, editing, and converting emails. It includes two APIs, Aspose.Email for C++ and Aspose.Words for C++, which can be used to convert EML file format to HTML, and then export HTML to EMF. Aspose.Email for C++ provides a wide range of features for working with emails, such as creating, reading, and converting emails. It also supports a variety of email formats, including EML, MSG, MHTML, and HTML. Aspose.Words for C++ is a powerful API for creating, editing, and converting documents. It supports a variety of document formats, including HTML, EMF, and PDF. With Aspose.Total for C++, you can easily convert EML to HTML, and then export HTML to EMF.
C++ API to Convert EML to EMF
- 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 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");
