Render EPUB to SWF within C++ Applications
Convert EPUB to SWF within your C++ Applications without using Microsoft® PowerPoint
Why to Convert EPUB to SWF?
EPUB is a popular format for digital books and publications, while SWF is a popular format for multimedia content. Converting EPUB to SWF allows developers to create interactive multimedia content from digital books and publications. This can be used to create engaging content for websites, presentations, and other applications.

Aspose.Total for C++ is a comprehensive suite of APIs that enables developers to easily integrate EPUB to SWF conversion into their C++ applications. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to export EPUB to PPTX and then convert PPTX to SWF. Both APIs are easy to use and provide a wide range of features to help developers create interactive multimedia content from digital books and publications. With Aspose.Total for C++, developers can quickly and easily add EPUB to SWF conversion to their C++ applications.
C++ API to Export EPUB to SWF
- Open EPUB file using Document class reference
- Convert EPUB 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 EPUB file with an instance of Document class
auto doc = MakeObject<Document>(u"template.epub");
// save EPUB 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 EPUB Document via C++
In the process of rendering EPUB to SWF, you can open a password protected EPUB and also change its password. In order to change the password of a EPUB 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 EPUB Document
auto doc = MakeObject<Document>(L"input.epub", L"owner");
// change password of EPUB 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 EPUB 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);
