在进行图像处理时，操作图像中的像素值就要得到图像阵列；经过处理后的图像的像素值需要存储起来；显示图像时要正确实现调色板、得到位图的尺寸信息等。结合这些问题，下面我们针对性的给出了操作灰度BMP图像时的部分函数实现代码及注释。-During image processing, the operation of the image pixel values ​ ​ will be the image array　processed image pixel values ​ ​ need to be stored　display images to correctly implement the palette to get the size of the bitmap information. With these issues, we targeted the following operation is given grayscale BMP image function when part of the implementation code and comments.
