Why to Convert
C++ developers often need to add email conversion features to their applications. One of the most common conversions is from OFT file format to HTML. This conversion is necessary for applications that need to display emails in a web browser.
How Aspose.Total Helps for OFT to PNG Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that provides developers with the tools they need to add powerful features to their applications. It includes two APIs that are useful for OFT to PNG conversion: Aspose.Email for C++ and Aspose.Words for C++.
Aspose.Email for C++ is an email conversion API that enables developers to convert OFT files to HTML. It supports a wide range of file formats, including Outlook MSG, EML, MHTML, and more. It also provides features such as email attachment extraction, message extraction, and more.
Aspose.Words for C++ is a document conversion API that enables developers to export HTML to PNG. It supports a wide range of file formats, including DOC, DOCX, ODT, and more. It also provides features such as document manipulation, document comparison, and more.
By using Aspose.Total for C++, developers can easily convert OFT files to HTML and then export HTML to PNG. This makes it easy to add powerful email conversion features to their applications.
C++ API to Convert OFT to PNG
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 OFT file to be converted System::SharedPtr<MailMessage> msg = MailMessage::Load(u"sourceFile.oft"); // save OFT 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 OFT File via C++
Not only you can convert your OFT to PNG, but you can read, manipulate, and parse OFT 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.oft"); // 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 OFT 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");

What is OFT File Format?
The OFT file format is associated with Microsoft Outlook and is used for creating email message templates. OFT stands for Outlook Form Template. It is a file format that allows users to design and save pre-formatted email templates with specific layouts, formatting, and content.
OFT files are typically used when users want to create consistent and standardized email messages for repetitive tasks or common communications. They can include placeholders for variables such as recipient names or subject lines, making it easier to personalize the template for individual recipients.
When an OFT file is opened in Microsoft Outlook, it creates a new email message based on the template design. Users can then customize the content, add or remove recipients, and make any necessary modifications before sending the email.
OFT files are particularly useful for businesses or individuals who frequently send similar types of emails, such as newsletters, announcements, or responses to common inquiries. By using OFT templates, users can save time and ensure consistency in their email communications.
It’s important to note that OFT files can only be opened and used with Microsoft Outlook. Other email clients or applications may not support this file format. Additionally, when sharing OFT templates with others, it is essential to ensure that they are using Microsoft Outlook to utilize the template properly.
What is PNG File Format?
PNG (Portable Network Graphics) is a widely used raster graphics file format that was designed as a replacement for the older GIF (Graphics Interchange Format) format. Unlike GIF, which has a limited color palette and supports only indexed colors, PNG supports true color and grayscale images with a rich color depth.
The PNG format utilizes lossless compression, which means that it can reduce file size without sacrificing image quality. This makes it suitable for storing graphics that require high detail and clarity, such as photographs, illustrations, and logos. PNG files are often used on the web for images that need transparency, as PNG supports alpha channel transparency, allowing for smooth blending of images onto different backgrounds.
One of the advantages of PNG is that it supports both interlaced and non-interlaced images. Interlaced PNGs load gradually, displaying a low-resolution version of the image before progressively rendering the higher-resolution details. This feature is especially useful for large images or slow internet connections, as it provides a better user experience by showing a preview while the image loads.
PNG files can be created and edited with various graphics software, such as Adobe Photoshop, GIMP, and Paint.NET. They are widely supported by modern web browsers, image viewers, and editing tools across different operating systems.
