Why to Convert
As a C++ developer, you may need to integrate EPUB to PPSM conversion feature inside your C++ applications. EPUB is a popular format for e-books, while PPSM is a Microsoft PowerPoint Show format. Converting EPUB to PPSM allows you to view the content of the e-book in a presentation format.
How Aspose.Total Helps for EPUB to PPSM Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that enables developers to create, manipulate, convert, and render documents in various formats. It includes APIs for PDF, Slides, and Words. With Aspose.Total for C++, you can easily export EPUB to PPTX and then convert PPTX to PPSM.
To export EPUB to PPTX, you can use Aspose.PDF for C++. It is a powerful PDF manipulation API that enables developers to create, read, edit, and convert PDF documents. It also supports conversion of PDF documents to other popular formats, including PPTX.
To convert PPTX to PPSM, you can use Aspose.Slides for C++. It is a powerful presentation manipulation API that enables developers to create, read, edit, and convert presentations. It also supports conversion of presentations to other popular formats, including PPSM.
Both APIs come under Aspose.Total for C++ package. With Aspose.Total for C++, you can easily export EPUB to PPTX and then convert PPTX to PPSM in two simple steps.
C++ API to Export EPUB to PPSM
- 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 PPSM format using
Save
member function and set
Ppsm
as 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 Ppsm format
prs->Save(u"output.ppsm", Aspose::Slides::Export::SaveFormat::Ppsm);
Change Password of EPUB Document via C++
In the process of rendering EPUB to PPSM, 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 PPSM File via C++
After converting EPUB to PPSM, 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 PPSM file
// instantiate a Presentation object that represents a PPSM file
auto pres = System::MakeObject<Presentation>("output.ppsm");
// 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.ppsm", SaveFormat::Ppsm);
