NPOI 2.0.6, XSSF namespace
- create a blank sheet in Excel (or enter a number)
- go to page setup, edit the header
- insert an image to the right side of the header
- save as xlsx
- open and save in npoi (do not change anything)
- open with Excel 2013 - it will crash on startup (it will not crash Office 2011 mac, however, the image will not be visible
The cause is an incorrectly written xl/drawings/vmldrawing.vml - replacing it with the original will bring the document back to life. I have not yet tracked down the root cause.
