Render XML to PPSM within C++ Applications
Convert XML to PPSM within your C++ Applications without using Microsoft® PowerPoint
Why to Convert XML to PPSM?
If you are a C++ developer, you may need to integrate XML to PPSM conversion feature inside your C++ applications. This is because PPSM is a file format that is used to store presentations created with Microsoft PowerPoint. It is a compressed version of the PPTX file format, which is used to store presentations created with Microsoft PowerPoint.
How Aspose.Total Helps for XML to PPSM Conversion?
Aspose.Total for C++ is a suite of APIs that can help you to easily export XML to PPTX and convert PPTX to PPSM. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++. With Aspose.PDF for C++, you can export XML to PPTX and with Aspose.Slides for C++, you can convert PPTX to PPSM. Both APIs come under the Aspose.Total for C++ package. This package provides you with a comprehensive set of APIs that can help you to easily integrate XML to PPSM conversion feature inside your C++ applications.
C++ API to Export XML to PPSM
- 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 PPSM format using
Save
member function and set
Ppsmas 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 Ppsm format
prs->Save(u"output.ppsm", Aspose::Slides::Export::SaveFormat::Ppsm);
Change Password of XML Document via C++
In the process of rendering XML to PPSM, 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 PPSM File via C++
After converting XML 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);
