记录一下图片格式转换 CogImage8Grey 转CMvdImage，ICogImage转CMvdImage同理

        //图像转换工具
        public class ImageConvetor 
        {
            public CMvdImage toMvdImage(CogImage8Grey cogImage)

                    cogImage8Root.GetRawPixelMemory(CogImageDataModeConstants.Read, 0, 0, cogImage.Width, cogImage.Height, out cogImage8PixelMemory);

                    int width = cogImage.Width;
                    int height = cogImage.Height;

                    Marshal.Copy(cogImage8PixelMemory.Scan0, SrcData, 0, (int)SrcData.Length);
                    CMvdImage tempImage = new CMvdImage();

                    tempImage.InitImage((uint)width, (uint)height, VisionDesigner.MVD_PIXEL_FORMAT.MVD_PIXEL_MONO_08, stData);
