marshalling - Marshal.Copy 导致暗恋

Question

我想在一个线程中翻转一张“tiff”的图片，但使用“Marshal.Copy”时可能会导致粉碎

我的代码：

public static bool ImageMirrorCv(ref int[] image, int width, int height, int mirrorNum)
    {
        try
        {
            //以X轴，垂直翻转
            if (mirrorNum == 0)
            {
                Mat mt = new Mat(height, width, MatType.CV_32F);
                if ((mt.Height * mt.Width) != image.Length)
                    return false;
                Marshal.Copy(image, 0, mt.Data, image.Count());
                Cv2.Flip(mt, mt, FlipMode.X);
                if ((mt.Height * mt.Width) != image.Length)
                    return false;
                Marshal.Copy(mt.Data, image, 0, image.Count());
            }
            //以Y轴，水平翻转
            else if (mirrorNum == 1)
            {
                Mat mt = new Mat(height, width, MatType.CV_32F);
                if ((mt.Height * mt.Width) != image.Length)
                    return false;
                Marshal.Copy(image, 0, mt.Data, image.Count());
                Cv2.Flip(mt, mt, FlipMode.Y);
                if ((mt.Height * mt.Width) != image.Length)
                    return false;
                Marshal.Copy(mt.Data, image, 0, image.Count());
            }
            //XY翻转
            else if (mirrorNum == -1)
            {
                Mat mt = new Mat(height, width, MatType.CV_32F);
                if ((mt.Height * mt.Width) != image.Length)
                    return false;
                Marshal.Copy(image, 0, mt.Data, image.Count());
                Cv2.Flip(mt, mt, FlipMode.XY);
                if ((mt.Height * mt.Width) != image.Length)
                    return false;
                Marshal.Copy(mt.Data, image, 0, image.Count());
            }
            else
            {

            }
            return true;
        }
        catch(Exception ex)
        {
            Utility.LogControl.Error(ex.ToString());
            return false;
        }
        
    }

params：image是一个arrary int[2048*2048]，高宽是2048，mirrorNum是flip的类型。通常是1，出现概率大约0.01%

事件查看器显示：
