Thanks for the template file.
After an initial test, I am able to observe the issue as you mentioned by re-saving his template XLSX file format. I found that embedded drawing objects becomes too narrow in the output file when re-saving the XLSX file via Aspose.Cells APIs:
Workbook wb = new Workbook("e:\\test2\\Original.xlsx"); wb.Save("e:\\test2\\out1.xlsx");
