C++ API to Convert DOT to PPSX or Online App
Export DOT to PPSX 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 PPSX format, which is a presentation format used by Microsoft PowerPoint.
How Aspose.Total Helps for DOT to PPSX Conversion
Aspose.Total for C++ is a suite of powerful file automation APIs that can be used to automate the conversion of DOT files to PPSX. The suite consists of two APIs: Aspose.Words for C++ and Aspose.Slides for C++. Aspose.Words for C++ can be used to load the DOT 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 a PPSX file. This process can be automated, allowing users to quickly and easily convert DOT files to PPSX.
DOT to PPSX 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 PPSX format using Save method and set Ppsx 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 Ppsx
pres->Save(output.ppsx, Aspose::Slides::Export::SaveFormat::Ppsx);

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 PPSX Document via C++
While saving DOT as PPSX, you can also use Aspose.Slides for C++ to add further features in your PPSX 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 Ppsx
pres->Save(output.ppsx, Aspose::Slides::Export::SaveFormat::Ppsx);
