title: Use .NET to extract cell range from xlsx file as image
body: <p>I'm looking for a way to extract cell range from a spreadsheet document as an image file without any user action.</p>
  
  <p>I able generating spreadsheet documents using OpenXML SDK.
  I want to define a cell range and use .NET to render these cells as Image.
  This function exists in Excel, I think it's possible to manage it using macro : <a href="https://stackoverflow.com/questions/8852656/export-bitmap-image-from-excel-cells">Export bitmap image from Excel cells</a>
  However I don't know if it exists a way to execute a macro with OpenXML SDK.</p>
  
  <p>Can someone help me ? Thank you.</p>
