Render EPUB to POTX within C++ Applications
Convert EPUB to POTX within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
If you are a C++ developer looking to add the ability to convert EPUB to POTX inside your C++ applications, then you need to use a reliable and efficient solution. This is because EPUB and POTX are two different file formats and require a conversion process to be able to use them together.
How Aspose.Total Helps for EPUB to POTX Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that allows developers to easily integrate document conversion features into their C++ applications. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to convert EPUB to POTX in two simple steps. First, you can use Aspose.PDF for C++ to export EPUB to PPTX. Then, you can use Aspose.Slides for C++ to convert PPTX to POTX. Both APIs are included in the Aspose.Total for C++ package, making it easy to access and use them.
C++ API to Export EPUB to POTX
- 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 POTX format using
Save
member function and set
Potxas 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 Potx format
prs->Save(u"output.potx", Aspose::Slides::Export::SaveFormat::Potx);
Change Password of EPUB Document via C++
In the process of rendering EPUB to POTX, 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 POTX File via C++
After converting EPUB to POTX, 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 POTX file
// instantiate a Presentation object that represents a POTX file
auto pres = System::MakeObject<Presentation>("output.potx");
// 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.potx", SaveFormat::Potx);
