C # split the desktop screenshot, compare the image streams, and redraw the original image from different images

For desktop screenshots, divide them into 16*8 pictures of the same size, and compare the screenshots with the original ones. If they are the same, they will not be sent. If they are different, they will be sent and overwritten.
