Why to Convert

RTF (Rich Text Format) is a document file format used to store documents with formatting information such as font, size, color, and layout. ODP (OpenDocument Presentation) is an open standard for electronic presentations, spreadsheets, and word processing documents. It is used to create presentations that can be shared across multiple platforms. Converting RTF to ODP allows users to create presentations that are compatible with multiple platforms and can be easily shared.

How Aspose.Total helps for rtf to odp conversion

Aspose.Total for C++ is a powerful file automation API that allows users to automate RTF to ODP conversion. It consists of two APIs, Aspose.Words for C++ and Aspose.Slides for C++. Aspose.Words for C++ can be used to load the RTF document and convert it to HTML. Aspose.Slides for C++ can then be used to load the HTML and create a new presentation. Finally, the presentation can be saved as an ODP file. This process allows users to quickly and easily convert RTF documents to ODP files, making them compatible with multiple platforms and easily shareable.

  4. Add an AutoShape in your slide, and add AddTextFrame in it
  5. Load the HTML content and write it in your Presentation file
  6. Save the document to ODP format using Save method and set Odp as SaveFormat

// load RTF file with an instance of Document
Document document = new Document("template.rtf");
System::SharedPtr<Document> doc = System::MakeObject<Document>(u"sourceFile.rtf");
// 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 Odp
pres->Save(output.odp, Aspose::Slides::Export::SaveFormat::Odp);

Load Password Protected RTF 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 RTF 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.rtf", options);

Add Comments in ODP Document via C++

While saving RTF as ODP, you can also use Aspose.Slides for C++ to add further features in your ODP 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 Odp
pres->Save(output.odp, Aspose::Slides::Export::SaveFormat::Odp);
