C# Image Convert: How to Convert Excel to Raster Images (Jpeg, Png, Bmp, & Gif)

If you want to convert Office Excel to raster image files (Jpeg, Png, Bmp and Gif) in your C# application, two aspects may be taken into consideration. One is only rendering a defined Excel sheet/page to a raster image. And the other is rendering the whole Excel file to a series of raster images. Considering that Excel document page/sheet has its own size, you need to set resolution for converted raster image.
