C++ API to Convert DOT to POTX or Online App
Export DOT to POTX 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, which are graphs with arrows pointing from one node to another. 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 POTX file format, which is used by Microsoft PowerPoint to store presentations.
How Aspose.Total helps for dot to potx 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 POTX files. The suite consists of two APIs: Aspose.Words for C++ and Aspose.Slides for C++. Using these APIs, it is possible to load a DOT file using Aspose.Words for C++, convert it to HTML, and then load the HTML via the PowerPoint manipulation C++ API Aspose.Slides for C++ to create a new presentation and save it as a POTX file. This process is simple and efficient, and can be used to quickly and easily convert DOT files to POTX files.
DOT to POTX 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 POTX format using Save method and set Potx 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 Potx
pres->Save(output.potx, Aspose::Slides::Export::SaveFormat::Potx);

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