C++ API to Export EML to PNG
Transform EML to PNG 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 a process of transforming emails from one format to another. For example, you may need to convert emails from EML file format to HTML.
How Aspose.Total helps for EML to PNG Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that enables developers to create, manipulate, convert, and render various file formats. 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 export HTML to PNG respectively.
Aspose.Email for C++ is a powerful API that enables developers to create, read, and manipulate emails in various formats. It supports a wide range of email formats such as EML, MSG, MHTML, and more. It also provides features to convert emails from one format to another. For example, you can use this API to convert EML file format to HTML.
Aspose.Words for C++ is a powerful API that enables developers to create, manipulate, and convert documents in various formats. It supports a wide range of document formats such as DOC, DOCX, ODT, HTML, and more. It also provides features to export HTML to PNG. For example, you can use this API to export HTML to PNG.
Both APIs come under Aspose.Total for C++ package. This package provides a comprehensive set of APIs that enables developers to create, manipulate, convert, and render various file formats. It includes APIs for working with emails, documents, images, and more. With Aspose.Total for C++, you can easily convert EML file format to HTML and export HTML to PNG.
C++ API to Convert EML to PNG
- 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 PNG format using Save method and set Png 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 Png as save format
doc->Save(u"convertedFile.Png");
Parse EML File via C++
Not only you can convert your EML to PNG, 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 PNG File Format Editing
You can also add document protection features in your app while exporting the document from EML to PNG. 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.Png");
