Render PDF to ODP within C++ Applications
Convert PDF to ODP within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
As a C++ developer, you may need to integrate PDF to ODP conversion feature inside your C++ applications. This is because PDF and ODP files are two different formats and the content of one format cannot be used in the other. PDF files are used for sharing documents and ODP files are used for creating presentations. Therefore, if you need to use the content of a PDF file in a presentation, you need to convert it to ODP format.
How Aspose.Total helps for pdf to odp conversion
Aspose.Total for C++ is a suite of APIs that can help you to convert PDF to ODP in two simple steps. First, you can use Aspose.PDF for C++ to export PDF to PPTX. Secondly, you can use Aspose.Slides for C++ to convert PPTX to ODP. Both APIs are available in the Aspose.Total for C++ package. The APIs are easy to use and you can quickly integrate them into your C++ applications. Moreover, the APIs are highly reliable and provide accurate results.
C++ API to Export PDF to ODP
- Open PDF file using Document class reference
- Convert PDF to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to ODP format using
Save
member function and set
Odpas 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 PDF file with an instance of Document class
auto doc = MakeObject<Document>(u"template.pdf");
// save PDF 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 Odp format
prs->Save(u"output.odp", Aspose::Slides::Export::SaveFormat::Odp);
Change Password of PDF Document via C++
In the process of rendering PDF to ODP, you can open a password protected PDF and also change its password. In order to change the password of a PDF 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 PDF Document
auto doc = MakeObject<Document>(L"input.pdf", L"owner");
// change password of PDF Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Add Images From Web in ODP File via C++
After converting PDF to ODP, 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 ODP file
// instantiate a Presentation object that represents a ODP file
auto pres = System::MakeObject<Presentation>("output.odp");
// 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.odp", SaveFormat::Odp);
