C++ API to Convert DOT to PPS or Online App
Export DOT to PPS within your C++ applications without using Microsoft Word® or PowerPoint
Why to Convert
The DOT file format is a text-based file format used to store diagrams created with the DOT language. It is used to represent directed graphs, and is often used to represent the structure of a program. However, the DOT file format is not supported by many applications, and so it is often necessary to convert DOT files to other formats. One such format is the PPS file format, which is a presentation format used by Microsoft PowerPoint.
How Aspose.Total Helps for DOT to PPS Conversion
Aspose.Total for C++ is a powerful suite of file automation APIs that allows developers to automate the conversion of DOT files to PPS files. It consists of two APIs: Aspose.Words for C++ and Aspose.Slides for C++. Using these APIs, developers can easily convert DOT files to PPS files.
The process begins by loading the DOT file using Aspose.Words for C++. This API allows developers to load and manipulate DOT files, and convert them to HTML. Once the DOT file is converted to HTML, the HTML can then be loaded using Aspose.Slides for C++. This API allows developers to manipulate PowerPoint presentations, and create new presentations from HTML. Finally, the new presentation can be saved as a PPS file.
Aspose.Total for C++ makes it easy for developers to automate the conversion of DOT files to PPS files. It provides powerful APIs that allow developers to quickly and easily convert DOT files to PPS files, without having to write complex code. This makes it an ideal solution for developers who need to automate the conversion of DOT files to PPS files.
DOT to PPS Conversion on C++
- Open DOT file using Document class reference
- Convert DOT 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 PPS format using Save method and set Pps 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 DOT file with an instance of Document
Document document = new Document("template.dot");
System::SharedPtr<Document> doc = System::MakeObject<Document>(u"sourceFile.dot");
// 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 Pps
pres->Save(output.pps, Aspose::Slides::Export::SaveFormat::Pps);

Load Password Protected DOT 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 DOT 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.dot", options);
Add Comments in PPS Document via C++
While saving DOT as PPS, you can also use Aspose.Slides for C++ to add further features in your PPS 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 Pps
pres->Save(output.pps, Aspose::Slides::Export::SaveFormat::Pps);
