Why to Convert
As a C++ developer, you may need to add email conversion features inside your applications. Email conversion is a process of transforming an email file format to another format. For example, you may need to convert an EMAIL file format to HTML.
How Aspose.Total helps for email to jpeg conversion
Aspose.Total for C++ is a comprehensive package of APIs that provides you with the ability to convert EMAIL file format to HTML. It includes two APIs, Aspose.Email for C++ and Aspose.Words for C++. Aspose.Email for C++ API allows you to convert EMAIL file format to HTML. After that, you can use Aspose.Words for C++ API to export HTML to JPEG. Both APIs come under Aspose.Total for C++ package. This package provides you with the ability to convert EMAIL file format to HTML and then export HTML to JPEG.
C++ API to Convert EMAIL to JPEG
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 Jpeg as save format doc->Save(u"convertedFile.Jpeg");
Parse EMAIL File via C++
Not only you can convert your EMAIL to JPEG, 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 JPEG File Format Editing
You can also add document protection features in your app while exporting the document from EMAIL to JPEG. 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.Jpeg");

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 JPEG File Format?
JPEG, short for Joint Photographic Experts Group, is a widely adopted standard for compressing photographic images. Developed by the International Organization for Standardization (ISO), JPEG employs a lossy compression algorithm to reduce the file size of images. During compression, certain image data is discarded, allowing for smaller file sizes. The extent of data loss can be adjusted, enabling users to balance file size and image quality according to their requirements.
As a highly popular format, JPEG finds extensive usage in storing and sharing photos. It is widely supported by various image editing software and web publishing platforms. Its compatibility makes it easy for users to work with JPEG files across different applications and platforms.
One of the key advantages of JPEG is its ability to significantly reduce file sizes while maintaining acceptable image quality. This makes it ideal for web-based image sharing, where smaller file sizes enable faster uploading and downloading. JPEG compression achieves higher levels of compression by eliminating redundant image information and exploiting the limitations of human visual perception. While this results in a loss of some image details, the trade-off between file size and image quality can be adjusted to suit specific needs.
