Render TEX to POTX within C++ Applications
Convert TEX to POTX within your C++ Applications without using Microsoft® PowerPoint
Are you a C++ developer looking to add to integrate TEX to POTX conversion feature inside your C++ applications? You can do it in two simple steps. You can export TEX to PPTX by using Aspose.PDF for C++ . Secondly, by using Aspose.Slides for C++ , you can convert PPTX to POTX. Both APIs come under Aspose.Total for C++ package.
C++ API to Export TEX to POTX
- Open TEX file using Document class reference
- Convert TEX to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to POTX format using
Save
member function and set
Potxas SaveFormat
Get Started with C++ File Automation 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 TEX file with an instance of Document class
auto doc = MakeObject<Document>(u"template.tex");
// save TEX as PPTX format
doc->Save(u"PptxOutput.pptx", SaveFormat::Pptx);
// instantiate a Presentation object that represents a PPTX file
SharedPtr<Presentation> prs = MakeObject<Presentation>(u"PptxOutput.pptx");
// save the presentation as Potx format
prs->Save(u"output.potx", Aspose::Slides::Export::SaveFormat::Potx);
Change Password of TEX Document via C++
In the process of rendering TEX to POTX, you can open a password protected TEX and also change its password. In order to change the password of a TEX file, you must know the owner password of that document. You can load password protected PDF document with Aspose.PDF for C++ by specifying its owner password and use ChangePasswords method to change the password.
// load an existing TEX Document
auto doc = MakeObject<Document>(L"input.tex", L"owner");
// change password of TEX Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Add Images From Web in POTX File via C++
After converting TEX to POTX, you can also add images from web to your output document. Aspose.Slides for C++ supports operations with images in these popular formats: JPEG, PNG, BMP, GIF, and others. You can add one or several images on your computer onto a slide in a presentation. This sample code in C++ shows you how to add an image to a POTX file
// instantiate a Presentation object that represents a POTX file
auto pres = System::MakeObject<Presentation>("output.potx");
// get slide
auto slide = pres->get_Slides()->idx_get(0);
// initialize Web Client
auto webClient = System::MakeObject<WebClient>();
// get image data
auto imageData = webClient->DownloadData(System::MakeObject<Uri>(u"[REPLACE WITH URL]"));
// add image
auto image = pres->get_Images()->AddImage(imageData);
// add picture frame
slide->get_Shapes()->AddPictureFrame(ShapeType::Rectangle, 10.0f, 10.0f, 100.0f, 100.0f, image);
// save updated file
pres->Save(u"updated.potx", SaveFormat::Potx);

What is TEX File Format?
A TEX file is a plain text file that contains the source code of a LaTeX document. LaTeX is a typesetting system used to create professional-looking documents. It is most commonly used to create papers for academic journals and to typeset books.TEX files are saved in the same directory as the LaTeX document and have a .tex file extension. They can be opened and edited with any text editor, but are typically viewed and compiled using a LaTeX editor, such as TeXnicCenter or Texmaker. When a TEX file is compiled, it is converted into a PDF or DVI file, which can be viewed with a PDF viewer, such as Adobe Reader, or a DVI viewer, such as Yap.

A POTX file is a PowerPoint Open XML Template file. It is a ZIP compressed XML file used by Microsoft PowerPoint to store slide designs. The POTX file format is used to save slide masters and layouts.POTX files can be opened by Microsoft PowerPoint and other presentation software that supports the PowerPoint Open XML format. They can also be opened by text editors such as Microsoft Word and Notepad++.Microsoft PowerPoint templates are pre-designed slide layouts that you can use to create presentations. Templates can contain slide masters, layouts, theme colors, theme fonts, theme effects, background styles, and slide design elements. You can use templates to create both new presentations and to modify existing presentations. When you open a template, it is copied to your hard drive and opened as a new, untitled presentation. The template file is not changed. You can save the new presentation as either a PowerPoint presentation (PPTX) or a PowerPoint template (POTX).
