Render XSLFO to OTP within C++ Applications
Convert XSLFO to OTP within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
Are you a C++ developer looking to add the ability to convert XSLFO to OTP inside your C++ applications? XSLFO (XSL Formatting Objects) is a markup language for XML document formatting which is most commonly used to generate PDF documents. OTP (OpenDocument Presentation) is an open standard for electronic documents which is used for presentations. Converting XSLFO to OTP can be useful for creating presentations from XML documents.
How Aspose.Total Helps for XSLFO to OTP Conversion
Aspose.Total for C++ is a comprehensive package of APIs which can be used to create, manipulate and convert various file formats. It includes Aspose.PDF for C++ and Aspose.Slides for C++ which can be used to convert XSLFO to OTP. To convert XSLFO to OTP, you can export XSLFO to PPTX by using Aspose.PDF for C++ and then convert PPTX to OTP by using Aspose.Slides for C++. Both APIs come under Aspose.Total for C++ package.
C++ API to Export XSLFO to OTP
- Open XSLFO file using Document class reference
- Convert XSLFO to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to OTP format using
Save
member function and set
Otpas 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 XSLFO file with an instance of Document class
auto doc = MakeObject<Document>(u"template.xslfo");
// save XSLFO 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 Otp format
prs->Save(u"output.otp", Aspose::Slides::Export::SaveFormat::Otp);
Change Password of XSLFO Document via C++
In the process of rendering XSLFO to OTP, you can open a password protected XSLFO and also change its password. In order to change the password of a XSLFO 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 XSLFO Document
auto doc = MakeObject<Document>(L"input.xslfo", L"owner");
// change password of XSLFO Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Add Images From Web in OTP File via C++
After converting XSLFO to OTP, 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 OTP file
// instantiate a Presentation object that represents a OTP file
auto pres = System::MakeObject<Presentation>("output.otp");
// 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.otp", SaveFormat::Otp);
