TeX is a typesetting system that has been noted as one of the most sophisticated digital typographical systems. TeX files are used for typesetting different documents and books containing text, symbols, and arithmetic expressions. Furthermore, these files can generate output in PNG, JPEG, TIFF, and BMP image formats. In this article, you will learn how to convert TeX files to images using C++.

C++ API for Converting TeX Files to Images
Aspose.TeX for C++ is a C++ library for working with TeX files without installing any additional software. The API allows you to typeset TeX files and generate output in PNG, JPEG, TIFF, and BMP image formats. You can either install the API through NuGet or download it directly from the Downloads section.
PM> Install-Package Aspose.TeX.Cpp
Convert TeX Files to JPG Images using C++
The following are the steps to convert TeX files to JPG images.
- Create an instance of the TeXOptions class using the TeXOptions::ConsoleAppOptions(System::SharedPtr config) method.
- Specify the input and output working directories.
- Specify console or memory stream as an output terminal.
- Set the save options to the instance of the JpegSaveOptions class.
- Save the output JPG image using the TeX::Typeset(System::String path, System::SharedPtrPresentation::Device device, System::SharedPtr options) method with an instance of the ImageDevice class.
The following sample code shows how to convert a TeX file to a JPG image using C++.
