Render SVG to SWF within C++ Applications
Convert SVG to SWF within your C++ Applications without using Microsoft® PowerPoint
Why to Convert SVG to SWF
C++ developers often need to integrate SVG to SWF conversion feature inside their applications. SVG (Scalable Vector Graphics) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. SWF (Small Web Format) is a vector file format used for multimedia, vector graphics and ActionScript. It is an Adobe Flash file format used for displaying animated vector graphics on the web. Converting SVG to SWF is a great way to make your graphics more interactive and engaging.
How Aspose.Total Helps for SVG to SWF Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that enables developers to create, manipulate and convert a wide range of file formats. It includes APIs for PDF, Slides, Words, Cells, Barcode, OCR, Imaging, Email, and many more. It also includes two APIs that can be used to convert SVG to SWF.
The first API is Aspose.PDF for C++. It can be used to export SVG to PPTX. It provides a set of features to create, read, edit, and convert PDF documents. It also supports the conversion of SVG to PPTX.
The second API is Aspose.Slides for C++. It can be used to convert PPTX to SWF. It provides a set of features to create, read, edit, and convert presentations. It also supports the conversion of PPTX to SWF.
Both APIs come under the Aspose.Total for C++ package. This makes it easy for developers to integrate SVG to SWF conversion feature inside their C++ applications in two simple steps.
C++ API to Export SVG to SWF
- Open SVG file using Document class reference
- Convert SVG 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 SVG file with an instance of Document class
auto doc = MakeObject<Document>(u"template.svg");
// save SVG 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 SVG Document via C++
In the process of rendering SVG to SWF, you can open a password protected SVG and also change its password. In order to change the password of a SVG 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 SVG Document
auto doc = MakeObject<Document>(L"input.svg", L"owner");
// change password of SVG 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 SVG 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 SVG File Format?
SVG (Scalable Vector Graphics) is a versatile and increasingly popular image format that offers several benefits for web designers and developers. Unlike other image formats, SVG uses mathematical equations instead of pixels to create smooth and scalable graphics, making it ideal for creating images that need to be displayed at different sizes and resolutions without losing quality.
One of the key advantages of SVG is that it is lightweight and fast loading, which is important for web-based applications that need to deliver a fast and seamless user experience. Since SVG files are vector-based, they are much smaller in size compared to other image formats, which means that they load faster and consume less bandwidth. This makes SVG particularly suitable for mobile devices and situations where bandwidth is limited.
Additionally, SVG offers a high level of interactivity and animation, making it ideal for creating dynamic user interfaces and engaging web experiences. SVG files can be easily animated using CSS or JavaScript, enabling designers and developers to create interactive graphics that respond to user input and system events. This is particularly useful for creating immersive web experiences, such as games, data visualizations, and e-learning applications.
Moreover, SVG files are editable using various software tools, allowing designers to modify and customize the graphics as needed. This flexibility enables quick iterations and easy collaboration between designers and developers.
Furthermore, SVG is compatible with all modern web browsers, making it widely supported across different platforms and devices. It also integrates well with other web technologies, such as HTML and CSS, enabling seamless integration with existing web projects.
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.
