Render MHTML to SWF within C++ Applications
Convert MHTML to SWF within your C++ Applications without using Microsoft® PowerPoint
Why to Convert MHTML to SWF?
If you are a C++ developer looking to add a feature to your applications that allows for the conversion of MHTML to SWF, then you have come to the right place. MHTML is a web page archive format that is used to store web pages and their associated resources. SWF is a vector-based file format used for multimedia, vector graphics, and ActionScript. Converting MHTML to SWF can be useful for creating interactive multimedia presentations, animations, and other interactive content.

Aspose.Total for C++ is a comprehensive suite of APIs that can help you with your MHTML to SWF conversion needs. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to export MHTML to PPTX and then convert PPTX to SWF. To export MHTML to PPTX, you can use Aspose.PDF for C++. This API allows you to convert MHTML to PPTX with just a few lines of code. Once you have the PPTX file, you can use Aspose.Slides for C++ to convert it to SWF. This API provides a wide range of features that can help you create high-quality SWF files from PPTX. With Aspose.Total for C++, you can easily and quickly convert MHTML to SWF.
C++ API to Export MHTML to SWF
- Open MHTML file using Document class reference
- Convert MHTML to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to SWF format using
Save
member function and set
Swfas SaveFormat
Get Started with C++ File Automation 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 MHTML file with an instance of Document class
auto doc = MakeObject<Document>(u"template.mhtml");
// save MHTML as PPTX format
doc->Save(u"PptxOutput.pptx", SaveFormat::Pptx);
// instantiate a Presentation object that represents a PPTX file
SharedPtr<Presentation> prs = MakeObject<Presentation>(u"PptxOutput.pptx");
// save the presentation as Swf format
prs->Save(u"output.swf", Aspose::Slides::Export::SaveFormat::Swf);
Change Password of MHTML Document via C++
In the process of rendering MHTML to SWF, you can open a password protected MHTML and also change its password. In order to change the password of a MHTML file, you must know the owner password of that document. You can load password protected PDF document with Aspose.PDF for C++ by specifying its owner password and use ChangePasswords method to change the password.
// load an existing MHTML Document
auto doc = MakeObject<Document>(L"input.mhtml", L"owner");
// change password of MHTML Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Add Images From Web in SWF File via C++
After converting MHTML to SWF, you can also add images from web to your output document. Aspose.Slides for C++ supports operations with images in these popular formats: JPEG, PNG, BMP, GIF, and others. You can add one or several images on your computer onto a slide in a presentation. This sample code in C++ shows you how to add an image to a SWF file
// instantiate a Presentation object that represents a SWF file
auto pres = System::MakeObject<Presentation>("output.swf");
// get slide
auto slide = pres->get_Slides()->idx_get(0);
// initialize Web Client
auto webClient = System::MakeObject<WebClient>();
// get image data
auto imageData = webClient->DownloadData(System::MakeObject<Uri>(u"[REPLACE WITH URL]"));
// add image
auto image = pres->get_Images()->AddImage(imageData);
// add picture frame
slide->get_Shapes()->AddPictureFrame(ShapeType::Rectangle, 10.0f, 10.0f, 100.0f, 100.0f, image);
// save updated file
pres->Save(u"updated.swf", SaveFormat::Swf);

What is MHTML File Format?
MHTML, short for MIME HTML, is a file format that combines HTML code and its associated resources into a single file. It stands for Multipurpose Internet Mail Extension HTML. MHTML files are commonly used for saving web pages, including all their content such as images, CSS stylesheets, and JavaScript, into a single file.
MHTML files are often created by web browsers when users save web pages for offline viewing or archiving purposes. By bundling all the necessary resources into one file, MHTML ensures that the web page can be viewed and rendered accurately, even without an internet connection or access to the original server.
The MHTML format follows the MIME standard, which is used for encoding and exchanging various types of data over the internet. It uses multipart MIME encoding to package the HTML code and associated resources into a single file. The file typically has a .mht or .mhtml file extension.
MHTML files can be opened and viewed by web browsers that support the format, such as Internet Explorer, Microsoft Edge, and Opera. Some text editors and specialized software also provide the ability to open and edit MHTML files.
The MHTML format offers advantages in terms of portability and convenience, as it allows users to save and share web pages as a single file, ensuring the preservation of the page’s layout, formatting, and linked resources. However, it’s worth noting that MHTML is not as widely used as other web formats like HTML or PDF, and compatibility may vary across different software and platforms.
What is SWF File Format?
The SWF (Shockwave Flash) file format is a popular multimedia format primarily used for delivering interactive and animated content on the web. Developed by Macromedia (now owned by Adobe Systems), SWF files are widely supported by web browsers and plug-ins, making them an integral part of web design and online entertainment.
SWF files are primarily composed of vector graphics, animation, audio, and video elements. They are created using software such as Adobe Animate (formerly known as Flash Professional) or other SWF authoring tools. The format supports interactivity through scripting languages like ActionScript, allowing developers to create interactive buttons, menus, and games within SWF files.
One of the key advantages of SWF files is their compact size. They are highly compressed, resulting in small file sizes that can be quickly downloaded and streamed over the internet. This makes SWF files ideal for delivering multimedia content efficiently, even on slower internet connections.
SWF files are often embedded into web pages, providing a seamless and engaging user experience. They can be played directly within web browsers using Adobe Flash Player or other SWF players. Additionally, SWF files can be standalone applications or screensavers, providing versatile usage beyond the web.
Over the years, the SWF format has evolved to support advanced features like 3D graphics, hardware acceleration, and multimedia streaming. However, it’s important to note that the usage of SWF files has declined in recent years due to the rise of alternative web technologies, such as HTML5 and CSS3, which offer similar capabilities without the need for additional plug-ins or proprietary software.
