We have problems saving Aspose.Cells .NET workbooks in .xlsx format - shapes with picture fills are empty (with incorrect solid fills), there’re no images attached to the .xlsx file as well. But everything is working well in the old Excel97To2003 format.
Bitmap image = new Bitmap(path);
ar shape = _workbook.Worksheets.Shapes.AddRectangle(0, 1, 0, 1, 1, 1);
shape.Placement = PlacementType.FreeFloating;
shape.LineFormat.IsVisible = false;
var ms = new MemoryStream();
shape.FillFormat.ImageData = ms.ToArray();
shape.FillFormat.Transparency = 0.5;
Thank you in advance for your help.
