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 emails from one format to another. This is done to make the emails compatible with different email clients and applications.
How Aspose.Total helps for eml to bmp conversion
Aspose.Total for C++ is a suite of APIs that provides a comprehensive set of features for manipulating emails, documents, and images. It includes Aspose.Email for C++ and Aspose.Words for C++. Aspose.Email for C++ allows you to convert EML file format to HTML. After that, Aspose.Words for C++ API can be used to export HTML to BMP. This makes it easy to convert emails from EML to BMP format.
C++ API to Convert EML to BMP
- 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 BMP format using Save method and set Bmp 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 Bmp as save format
doc->Save(u"convertedFile.Bmp");
Parse EML File via C++
Not only you can convert your EML to BMP, 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 BMP File Format Editing
You can also add document protection features in your app while exporting the document from EML to BMP. 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.Bmp");
