Hi,
setting a background image using Aspose.Cells 21.9.0 does not work.
Background.jpg (128.2 KB)
var workbook = new Workbook();
var sheet = workbook.Worksheets[0];
sheet.BackgroundImage = File.ReadAllBytes("Documents/Background.jpg");
// background image is not set!
workbook.Save(Path.Combine(Environment.CurrentDirectory, "ExcelWithBackground.xlsx"));
Best regards
