Mark, Thanks for your reply, but I don't mean what you said.
I re-explain my test steps here: 1.1 Use Excel to new an Excel workbook 1.2 Use POI to open it and insert an image 1.3 Call HSSFPicture.resize() 1.4 Save and close it 2.1 Use Excel to new an Excel workbook 2.2 Use Excel to modify the default font size (For example, from 10 to 20) 2.3 Save and close it 2.4 Use POI to oepn it and insert the same image used in the previous test 2.5 Call HSSFPicture.resize() 2.6 Save and close it Now, use Excel to open these two workbooks, as illustated in prevous threads, you can see the same image in these workbooks do NOT have the same size! The later one stretchs horizontally! BTW, I tried the code you mentioned, but it still only works when the default font size not changed yet.
