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 an email file format into another format. This is useful for a variety of reasons, such as archiving emails, sharing emails with other users, or for compatibility with other applications.
How Aspose.Total Helps for Email to EMF Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that provides developers with the tools they need to create powerful applications. It includes two APIs that are specifically designed for email conversion: Aspose.Email for C++ and Aspose.Words for C++.
Aspose.Email for C++ allows developers to convert EMAIL file format to HTML. Aspose.Words for C++ then allows developers to export HTML to EMF. This makes it easy to convert emails into a format that is compatible with other applications.
Aspose.Total for C++ is a great choice for developers who need to add email conversion features to their applications. It provides the tools necessary to quickly and easily convert emails into a variety of formats. With Aspose.Total for C++, developers can easily add email conversion features to their applications.
C++ API to Convert EMAIL to EMF
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
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load the EMAIL file to be converted System::SharedPtr<MailMessage> msg = MailMessage::Load(u"sourceFile.msg"); // save EMAIL 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 EMAIL File via C++
Not only you can convert your EMAIL to EMF, but you can read, manipulate, and parse EMAIL 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.msg"); // 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 EMAIL 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");

What is EMAIL File Format?
An email file adheres to a specific format that is recognized by email programs. It comprises a header section and a body section, separated by a blank line. The header contains essential information such as the sender’s email address, recipient’s email address, subject of the email, and the date and time it was sent. The body of the email contains the actual message being conveyed. Email files can exist in either plain text or HTML format. However, HTML emails have become more prevalent in recent times due to their ability to incorporate images and other formatting elements.
The header of an email file provides crucial metadata that aids in routing and organizing messages. It allows the email program to identify the sender, recipient, subject, and timestamp. The body section contains the content of the email, which may include text, images, hyperlinks, and other media elements. While plain text emails are simple and accessible across various devices and email clients, HTML emails offer more design flexibility and interactivity.
With the widespread usage of HTML emails, senders can create visually appealing and engaging messages. HTML emails allow for the inclusion of branding elements, formatting styles, and multimedia content, thereby enhancing the overall presentation and user experience.
What is EMF File Format?
The EMF file format, short for Enhanced Metafile, is a widely used vector graphics file format developed by Microsoft. EMF files are primarily used to store and exchange 2D graphical images and are supported by various applications and operating systems.
EMF files are based on the Windows Graphics Device Interface (GDI) and consist of a series of drawing commands, shapes, and text instructions that define the image. Unlike bitmap formats, EMF files store graphical elements as scalable objects rather than a grid of pixels. This allows for smooth scaling and resizing without loss of quality.
EMF files are commonly used in applications where high-quality graphics and printing are essential, such as graphic design, desktop publishing, and document processing. They can be easily inserted into other Microsoft Office applications like Word, PowerPoint, or Excel, allowing for the incorporation of complex illustrations or diagrams into documents.
One advantage of EMF files is their compact size, as they are typically smaller than equivalent bitmap images. Additionally, they can be easily edited and modified using vector graphics software, providing flexibility in terms of adjusting colors, shapes, and other graphical properties.
