Excel Rendering to REImage in C# Overview
It is necessary to render Microsoft Excel to REImage (a self-defined image object in our program, similar to the concept of Bitmap in .NET programming) in C#.NET because our
Excel Conversion SDK for C#.NET does not allows you to directly convert Excel file to other document and image formats.
