如何设置边框到ExcelPicture框

Question

Bitmap image = new Bitmap(pImagePath);
            OfficeOpenXml.Drawing.ExcelPicture excelImage = null;
            if (image != null)
            {
                excelImage = excelWorksheet.Drawings.AddPicture("Name", image);
                excelImage.From.Column = 0; 
                excelImage.From.Row = 6; 
                excelImage.SetSize(230, 168);

                excelImage.From.ColumnOff = 19050;
                excelImage.From.RowOff = 19050;
                image.Dispose();
            }

它将在ExcelPicture中显示完整的图像。但我必须在ExcelPicture附近设置边框。
