with color block, each occurrence need to add (m-1) * (n-1), this calculation I did not find a more ideal algorithm, I am flexible, only calculate the most chance of the small rectangle,2Then say generate Bitmap, bitmap. Since there are only 2 colors, a bitmap with 1 bit will not be large without compression. One thing to note here is that the layout of the bitmap is the last line to write first, then up, and the total number of bytes per row, must be a multiple of 4, such as a version3
