对彩色图像去黑边和去装订孔时，提示出错

源码：

      //去黑边
      public void BorderRemove(RasterImage image)
      {

            BorderRemoveCommand command = new BorderRemoveCommand();
            command.Border = BorderRemoveBorderFlags.All;
            command.Flags = BorderRemoveCommandFlags.UseVariance;
            command.Percent = 20;
            command.Variance = 3;
            command.WhiteNoiseLength = 9;
            command.Run(image);

      }
      //去装订孔
      public void HolePunchRemove(RasterImage image)
      {
         HolePunchRemoveCommand command = new HolePunchRemoveCommand();
         command.Location = HolePunchRemoveCommandLocation.Left | HolePunchRemoveCommandLocation.Top;
         command.Run(image);
      }

同事们以前都是用其它插件的这两个功能，据说对彩色图像也可以做到去黑边和去装订孔，不知道咱们这边有没有解决办法
