Why to Convert

TXT to ODP conversion is a useful process for many reasons. ODP is a presentation format used by OpenOffice and LibreOffice, and is a popular choice for creating presentations. It is also a great way to share documents with others, as it is compatible with many different programs. Additionally, ODP files are smaller in size than TXT files, making them easier to store and share.

How Aspose.Total Helps for TXT to ODP Conversion

Aspose.Total for C++ is a powerful file automation API that allows users to automate TXT 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 a TXT file and convert it to HTML. Aspose.Slides for C++ can then be used to load the HTML and create a new presentation, which can then be saved as an ODP file. This process is simple and efficient, and allows users to quickly and easily convert TXT files to ODP files.

TXT to ODP Conversion on C++

  1. Open TXT file using Document class reference
  2. Convert TXT to HTML by using Save member function
  3. Initialize a new Presentation object
  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

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 Install-Package Aspose.Total.Cpp.

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 Odp
pres->Save(output.odp, Aspose::Slides::Export::SaveFormat::Odp);

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 ODP Document via C++

While saving TXT 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);
