Why to Convert

Converting DOTM to PPTX is a common requirement for many businesses. DOTM is a Microsoft Word template file that is used to create documents with a consistent look and feel. It is a great way to ensure that all documents created from the template have the same formatting and layout. However, DOTM files are not compatible with PowerPoint, so they must be converted to PPTX in order to be used in PowerPoint presentations.

Aspose.Total for C++ is a powerful file automation API that allows users to automate the conversion of DOTM to PPTX. It consists of two APIs: Aspose.Words for C++ and Aspose.Slides for C++. Aspose.Words for C++ can be used to load the DOTM file and convert it to HTML. Aspose.Slides for C++ can then be used to load the HTML and create a new presentation in PPTX format. This process is quick and easy, and it ensures that the formatting and layout of the original DOTM file is preserved in the PPTX file.

System::SharedPtr<Document> doc = System::MakeObject<Document>(u"sourceFile.dotm");
// 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 DOTM 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 DOTM 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.dotm", options);

Add Comments in PPTX Document via C++

While saving DOTM as PPTX, you can also use Aspose.Slides for C++ to add further features in your PPTX 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);
