浅谈Visual C#进行图像处理（读取、保存以及对像素的访问）

                        Data[i, j] = (byte)temp;
                    }
                    ptr += bmpData.Stride - Width * 3;//指针加上填充的空白空间
                }
            }
            bmp.UnlockBits(bmpData);
        }
        public GrayBitmapData(string path)
            : this(new Bitmap(path))

            Bitmap bmp=new Bitmap(Width,Height,PixelFormat.Format24bppRgb);
            BitmapData bmpData=bmp.LockBits(new Rectangle(0,0,Width,Height),ImageLockMode.WriteOnly,PixelFormat.Format24bppRgb);
            unsafe
            {
                byte* ptr=(byte*)bmpData.Scan0.ToPointer();
