C++ API to Convert EML to PDF

  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 PDF format using Save method and set Pdf 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 Pdf as save format
doc->Save(u"convertedFile.Pdf");

Parse EML File via C++

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

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

What is EML File Format?

The EML file format, standing for Electronic Mail, is a widely used file format for storing email messages. It is primarily associated with email clients such as Microsoft Outlook, Mozilla Thunderbird, and Windows Mail. EML files contain the entire contents of an email message, including the sender and recipient information, subject, date, attachments, and the message body.

EML files are formatted in plain text and adhere to the Multipurpose Internet Mail Extensions (MIME) standard, which allows for the inclusion of various types of content within an email message, such as text, images, and attachments. This makes EML files highly versatile and compatible with different email clients and platforms.

The EML format is commonly used for archiving or transferring individual email messages. It provides a convenient way to store emails as separate files, making it easier to organize and retrieve specific messages when needed. EML files can be opened and viewed in compatible email clients, allowing users to read and interact with the contents of the email message.

Furthermore, EML files can be easily shared via email or other file transfer methods. They preserve the original formatting, ensuring that the recipient sees the email exactly as it was sent, including any attachments or embedded images.

In addition to being used for individual email messages, EML files are also used in email migration and backup processes. They allow for the transfer of email messages between different email clients or the creation of backups to safeguard important communications.

What is PDF File Format?

PDF, or Portable Document Format, is a file format designed for presenting documents in a manner that remains consistent across various software applications, hardware devices, and operating systems. Each PDF file contains a comprehensive description of a fixed-layout document, encompassing text, fonts, graphics, and other necessary information for accurate display. Initially developed by Adobe Systems in the early 1990s, PDF served as a means to share computer documents while preserving text formatting and inline images.

PDF files are typically generated using software like Adobe Acrobat or similar PDF creation tools. Presently, PDF has become an open standard governed by the International Organization for Standardization (ISO). This standardization ensures compatibility and interoperability across different platforms and systems. To view PDF files, users can utilize free software such as Adobe Reader or other PDF viewers available.

One of the significant advantages of PDF is its platform independence, allowing seamless viewing and printing on a wide range of devices and operating systems. Regardless of the hardware or software used, the document’s layout and content will remain intact. This universal accessibility has contributed to the popularity of PDF as a preferred format for sharing and distributing documents across diverse platforms and systems.

PDF’s capability to encapsulate a complete document, including text, fonts, graphics, and formatting, makes it a reliable choice for various applications. Whether it’s sharing important reports, publishing e-books, distributing forms, or delivering professional presentations, PDF ensures consistent document rendering and reliable preservation of content across different environments.
