Render XML to OTP within C++ Applications
Convert XML to OTP within your C++ Applications without using Microsoft® PowerPoint
Why to Convert XML to OTP?
XML to OTP conversion is a useful feature for C++ developers who want to add extra functionality to their applications. OTP (One-Time Password) is a secure authentication method used to protect user accounts from unauthorized access. It is a unique code that is generated for a single use and expires after a certain amount of time. By converting XML to OTP, developers can ensure that their applications are secure and user accounts are protected.
How Aspose.Total Helps for XML to OTP Conversion?
Aspose.Total for C++ is a comprehensive suite of APIs that provides developers with the tools they need to create powerful applications. It includes two APIs that can be used to convert XML to OTP: Aspose.PDF for C++ and Aspose.Slides for C++. With Aspose.PDF for C++, developers can export XML to PPTX. Then, with Aspose.Slides for C++, they can convert PPTX to OTP. Both APIs are included in the Aspose.Total for C++ package, making it easy for developers to add XML to OTP conversion feature to their C++ applications.
C++ API to Export XML to OTP
- Open XML file using Document class reference
- Convert XML 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 XML file with an instance of Document class
auto doc = MakeObject<Document>(u"template.xml");
// save XML 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 XML Document via C++
In the process of rendering XML to OTP, you can open a password protected XML and also change its password. In order to change the password of a XML 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 XML Document
auto doc = MakeObject<Document>(L"input.xml", L"owner");
// change password of XML 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 XML 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);
