能否给datagridview的列头设置背景图片？

Question

找了半天没有找到，貌似只能设置背景颜色？是在不行设置为渐进色也行啊。
谢谢了。

//行头，列头背景颜色渐变  
 protected override void OnCellPainting(System.Windows.Forms.DataGridViewCellPaintingEventArgs e)
       {
           Color mLinearColor1 = Color.FromArgb(51, 122, 167);
           Color mLinearColor2 = Color.FromArgb(255, 255, 255);
           Color mGridColor = Color.FromArgb(120, 147, 191);  //网格线的颜色           Rectangle Rect = new Rectangle(e.CellBounds.X - 1, e.CellBounds.Y, e.CellBounds.Width, e.CellBounds.Height - 1);
           LinearGradientBrush LinearGradientBrushs = new LinearGradientBrush(Rect, mLinearColor1, mLinearColor2, LinearGradientMode.Vertical);
           
           try
           {
                   if (e.RowIndex == -1 || e.ColumnIndex == -1)
                   {
                       e.Graphics.FillRectangle(LinearGradientBrushs, Rect);
                       e.Graphics.DrawRectangle(new Pen(mGridColor), Rect);
                       e.PaintContent(e.CellBounds);
                       e.Handled = true;
                   }
           }           catch
           { }
           finally
           {
               if (LinearGradientBrushs != null)
               {
                   LinearGradientBrushs.Dispose();
               }           }           base.OnCellPainting(e);
       }
