Aspose.Total for C++ consists of powerful file automation APIs that allows to automate TXT to POWERPOINT conversion while using two of it’s APIs. Load your TXT using Aspose.Words for C++ and convert it to HTML, then load the HTML via PowerPoint manipulation C++ API Aspose.Slides for C++ to create a new presentation, and save it as POWERPOINT.
TXT to POWERPOINT Conversion on C++
- Open TXT file using Document class reference
- Convert TXT to HTML by using Save member function
- Initialize a new Presentation object
- Add an AutoShape in your slide, and add AddTextFrame in it
- Load the HTML content and write it in your Presentation file
- Save the document to PPTX format using Save method and set Pptx as SaveFormat
Get Started with C++ File Format APIs
Install from command line as
nuget install Aspose.Total.Cpp or via Package Manager Console of Visual Studio with
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load TXT file with an instance of Document Document document = new Document("template.txt"); System::SharedPtr<Document> doc = System::MakeObject<Document>(u"sourceFile.txt"); // 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 Pptx pres->Save(output.pptx, Aspose::Slides::Export::SaveFormat::Pptx);
Load Password Protected TXT 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 TXT 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.txt", options);
Add Comments in POWERPOINT Document via C++
While saving TXT as POWERPOINT, you can also use Aspose.Slides for C++ to add further features in your POWERPOINT 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 Pptx pres->Save(output.pptx, Aspose::Slides::Export::SaveFormat::Pptx);

TXT What is TXT File Format?
A file with .TXT extension represents a text document that contains plain text in the form of lines. Paragraphs in a text document are recognized by carriage returns and are used for better arrangement of file contents.
