Thanks for your issue. This is related to #260 and #279. The actual image size may be inconsistent between different spreadsheet applications. For example, the image scale shows 100% in Microsoft Excel 2007 and 2010 but not in Microsoft Excel 2016. The reason for that was columns width and row height depend on the display device resolution, so please adjust the image scale manually to fit your priority environments. I think this issue can be closed, and merged into #260 to continue to discuss this problem.
