FarPoint.Win.Serializer.LoadObjectXml复制SheetView副本时，提示调用的目标时发异常

复制SheetView,按照：http://blog.gcpowertools.com.cn/post/如何复制SheetView对象-.aspx：public FarPoint.Win.Spread.SheetView CopySheet(FarPoint.Win.Spread.SheetView sheet)    {        FarPoint.Win.Spread.SheetView newSheet = null;        if (sheet != null)        {            newSheet = FarPoint.Win.Serializer.LoadObjectXml(typeof(SheetView), FarPoint.Win.Serializer.GetObjectXml(sheet, "CopySheet"), "CopySheet") as SheetView;            newSheet.SheetName = "NewSheet";        }        return newSheet;    }-------------------------------------------------当其中某个单元格有背景时复制出错（出错提示在上传图片中）：TextCellType cellType = new TextCellType();cellType.BackgroundImage = new Picture(Image.FromFile(@"c:\xx.jpg"), FarPoint.Win.RenderStyle.Stretch, System.Drawing.Color.Empty, 0, FarPoint.Win.HorizontalAlignment.Left, FarPoint.Win.VerticalAlignment.Top);
this.fpSpread_Sheet1.Cells[0,0].CellType = cellType;

单元格设置背景：http://gcdn.gcpowertools.com.cn/ ... =%B1%B3%BE%B0%CD%BC

且导出Excel表时出现GDI+错误。

您好，我测试您的代码没有出现异常，可否提供一个Demo；

1.             var sheet = fpSpread1.ActiveSheet;
   
2.             TextCellType cellType = new TextCellType();
   
3.             cellType.BackgroundImage = new FarPoint.Win.Picture(Image.FromFile(@"googlelogo_color_120x44dp.png"),
   
4.                 FarPoint.Win.RenderStyle.Stretch, System.Drawing.Color.Empty, 0, FarPoint.Win.HorizontalAlignment.Left, FarPoint.Win.VerticalAlignment.Top);
   
5.             sheet.Cells[0, 0].CellType = cellType;
   
6. 
   
7. 
   
8. 
   
9.             FarPoint.Win.Spread.SheetView newSheet = null;
   
10.             newSheet = FarPoint.Win.Serializer.LoadObjectXml(typeof(SheetView), FarPoint.Win.Serializer.GetObjectXml(sheet, "CopySheet"), "CopySheet") as SheetView;
    
11.             newSheet.SheetName = "NewSheet";
    
12. 
    
13. 
    
14.             fpSpread1.Sheets.Add(newSheet);
