How to create equations using LaTeX and convert them to images in C# .NET Core Word?

Syncfusion® Essential® DocIO is a .NET Core Word Library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can create equations using LaTeX in a Word document and convert them to images using C#.

Steps to create equations using LaTeX and convert them to images using C#

1. Create a new C# Console application project.
2. Install the Syncfusion.DocIORenderer.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in the Program.cs file:
   C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;

4. Use the following code snippet to create equations using LaTeX in a Word document and convert them to images.
   C#

// Create a new Word document.
using (WordDocument document = new WordDocument())
{
   // Add one section and one paragraph to the document.
   document.EnsureMinimal();

   // Append an accent equation using LaTeX.
   document.LastParagraph.AppendMath(@"f\left(x\right)={a}_{0}+\sum_{n=1}^{\infty}{\left({a}_{n}\cos{\frac{n\pi{x}}{L}}+{b}_{n}\sin{\frac{n\pi{x}}{L}}\right)}");
   
   // Instantiation of DocIORenderer for Word to PDF conversion.
   DocIORenderer render = new DocIORenderer();
   // Convert the first page of the Word document into an image.
   Stream imageStream = document.RenderAsImages(0, ExportImageFormat.Jpeg);
   // Reset the stream position.
   imageStream.Position = 0;
   // Save the stream as a file.
   using (FileStream fileStreamOutput = File.Create("../../../Result.jpeg"))
   {
       imageStream.CopyTo(fileStreamOutput);
   }
   // Close the Word document.
   document.Close();
}

You can download a complete working sample of creating equations using LaTeX and converting them to images from GitHub.

By executing the program, you will get the Word document as follows:

Take a moment to peruse the documentation where you can find basic Word document processing options along with features like mail merge, merge, split, and compare Word documents, find and replace text in the Word document, protect Word documents, and most importantly, the PDF and Image conversions with code examples.
