Excel Sparklines don't get saved in rendered image

We have an established system that uses Aspose Cells (ver to open existing Excel workbooks and render specified worksheets from them to images. This has been working fine, but recently we tried to use it with some Excel 2010 worksheets that contained Sparkline objects and these fail to be reproduced in any way on the final rendered images.

Is this a known issues? Does version support rendering Sparkline objects?

Our code is very simple and the problem is easy to reproduce:

Workbook book = new Workbook(“TheBook.xlsx”);
Worksheet sheet = book.Worksheets[0];
Aspose.Cells.Rendering.ImageOrPrintOptions imgOptions = new Aspose.Cells.Rendering.ImageOrPrintOptions();
imgOptions.ImageFormat = System.Drawing.Imaging.ImageFormat.Bmp;
Aspose.Cells.Rendering.SheetRender sr = new Aspose.Cells.Rendering.SheetRender(sheet, imgOptions);
Image image = sr.ToImage(0);

Please advise!
