C++ API to Convert ODT to PPSM or Online App
Export ODT to PPSM within your C++ applications without using Microsoft Word® or PowerPoint
Why to Convert
The OpenDocument Text (ODT) format is a popular open source document format used for creating and editing text documents. It is widely used for creating documents such as letters, reports, and books. However, it is not compatible with many other applications, such as Microsoft PowerPoint. Therefore, it is necessary to convert ODT documents to a format that is compatible with PowerPoint, such as the PowerPoint Show (PPSM) format.

System::SharedPtr<Document> doc = System::MakeObject<Document>(u"sourceFile.odt");
// save the document in HTML file format
doc->Save(u"HtmlOutput.HTML");
// load the desired the presentation
SharedPtr<Presentation> pres = MakeObject<Presentation>();
// access first slide
SharedPtr<ISlide> sld = pres->get_Slides()->idx_get(0);
// add an AutoShape of Rectangle type
SharedPtr<IAutoShape> ashp = sld->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 10, 10, 700, 500);
// reset default fill color
ashp->get_FillFormat()->set_FillType(FillType::NoFill);
// add TextFrame to the Rectangle
ashp->AddTextFrame(u" ");
// access the text frame
SharedPtr<ITextFrame> txtFrame = ashp->get_TextFrame();
// get Paragraphs collection
SharedPtr<Aspose::Slides::IParagraphCollection>ParaCollection = txtFrame->get_Paragraphs();
// clear all paragraphs in added text frame
ParaCollection->Clear();
// load the HTML file using stream reader
SharedPtr<System::IO::StreamReader> tr = MakeObject<System::IO::StreamReader>(HtmlOutput.HTML);
// add text from HTML stream reader in text frame
ParaCollection->AddFromHtml(tr->ReadToEnd());
// save presentation as Ppsm
pres->Save(output.ppsm, Aspose::Slides::Export::SaveFormat::Ppsm);

Load Password Protected ODT Document via C++
Apart from document conversion, Aspose.Words for C++ API allows tons of document manipulation features for C++ developers. In case your Microsoft Word ODT file format is password protected, you can still open it using the API. In order to load the encrypted document, you can use a special constructor overload, which accepts a LoadOptions object. This object contains the Password property, which specifies the password string.
// when loading password protected document, the password is passed to the document's constructor using a LoadOptions object.
auto options = MakeObject<LoadOptions>(u"docPassword");
// load the document from the local file system by filename:
SharedPtr<Document> doc = MakeObject<Document>(u"Encrypted.odt", options);
Add Comments in PPSM Document via C++
While saving ODT as PPSM, you can also use Aspose.Slides for C++ to add further features in your PPSM document. For instance, you can add comments in your presentation. The presentation slide comment are associated with a particular author. The Presentation class holds the collection of authors in ICommentAuthorCollection that are responsible for adding slide comments. For each author, there is a collection of comments in ICommentCollection.
// instantiate Presentation class
SharedPtr<Presentation>pres = MakeObject<Presentation>();
// access first slide
SharedPtr<ILayoutSlide>layout = pres->get_LayoutSlides()->idx_get(0);
// add empty slide
pres->get_Slides()->AddEmptySlide(layout);
// adding Author
SharedPtr<ICommentAuthor> author = pres->get_CommentAuthors()->AddAuthor(u"John Doe", u"MF");
// set position of comments
System::Drawing::PointF point = System::Drawing::PointF(0.2f, 0.2f);
// add slide comment for an author on slide 1
author->get_Comments()->AddComment(u"Hello John, this is a slide comment", pres->get_Slides()->idx_get(1), point, DateTime::get_Now());
// access ISlide 1
SharedPtr<ISlide> slide = pres->get_Slides()->idx_get(0);
// save presentation as Ppsm
pres->Save(output.ppsm, Aspose::Slides::Export::SaveFormat::Ppsm);
