Convert OpenXML Microsoft native word equation to png file using C#

We are working on a small ASP.NET C# Word document parsing project where we need to convert Word content to HTML. We cannot use Word's save as HTML option. We are using OpenXML 2.5 library to parse the word document. We are able to convert everything else but equations created using Microsoft Word Equations which exist as OMathPara. We need to extract and convert OMML to png file. We are looking for C# code to perform this. A sample equation file is attached.
